How do you reference the proxy.ashx page?

MatthewGerbrandt

Hello there. I've got some secured ArcGIS Services that require a token. I've got my proxy.ashx and proxy.config pages in place and configured.

The last thing I need to do is figure out how to get my JS/HTML pages to reference those proxy pages and pass the token to the services.

If someone could please post some code or point me to an example, I'd be tremendously grateful. The info at http://resources.esri.com/help/9.3/arcgisserver/apis/javascript/arcgis/help/jshelp_start.htm#jshelp/ags_proxy.htm wasn't helpful because my pages don't have a code-behind page for the C# code.

Thanks a million in advance!!

Hello, if you are using a proxy page and the JSAPI . In your JS code, sometime prior to making a request from a service you would set esri.config.defaults.io.proxyUrl to the url of your ashx page.

All the examples from your link are for use inside your JS code, They just demonstrate how you would call your proxy page based on your server side implementation

In side your ashx page would reside the secured urls and the token generated from the getToken rest endpoint that can access those service(s), no need to pass the token to your services as the proxy will do the authentication on your behalf

Thank you very much for your answer. I've added the following code to my web page:

esri.config.defaults.io.proxyUrl = "proxy.ashx"; // that is the correct path

And I'm getting the following error:

Webpage error details

Message: 'esri.config.defaults' is null or not an object

Looks like I need to add a reference somewhere. Can anyone point me in the right direction?

HaroldBostic

Hello, an example is here:

http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples/routetask_directions.html

is your call inside a dojo.addOnLoad call like dojo.addOnLoad(init);? If not the esri namespace may not be loaded yet and it could be a timing issue.

Hope that helps.

MatthewGerbrandt

Thank you very much, Harold. I think I'm closer to getting there but my code still isn't retrieving a token from the proxy page.

Here's the JavaScript code:

<script type="text/javascript">
    dojo.require("esri.map");
    dojo.require("dijit.layout.ContentPane");
    dojo.require("dijit.layout.BorderContainer");
    var map;
    function Init() {

        esri.config.defaults.io.proxyUrl = "../proxy.ashx"; 
        dojo.style(dojo.byId("map"), { width: dojo.contentBox("map").w + "px", height: (esri.documentBox.h - dojo.contentBox("navTable").h - 40) + "px" });
        map = new esri.Map("map");
        
        var CountyDataLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://servername/ArcGIS/rest/services/Counties/MapServer");
        map.addLayer(CountyDataLayer);

// the following service requires a token:
        var RestrictedLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://servername/ArcGIS/rest/services/Cadaster/CadasterLayerHalfTransparent/MapServer");

        map.addLayer(RestrictedLayer);
        
        
        var resizeTimer;
        dojo.connect(map, 'onLoad', function(theMap) {
            dojo.connect(dijit.byId('map'), 'resize', function() {
                clearTimeout(resizeTimer);
                resizeTimer = setTimeout(function() {
                    map.resize();
                    map.reposition();
                }, 500);
            });
        });
    }
    dojo.addOnLoad(Init);
</script>

and here's the code from the proxy.ashx page:

<?xml version="1.0" encoding="utf-8" ?>
<!-- Proxy config is used to set the ArcGIS Server services that the proxy will forward to.
        
        mustMatch: true to only proxy to sites listed, false to proxy to any site -->
<ProxyConfig mustMatch="true">
  <serverUrls>
    <!-- serverUrl options:
            url = location of the ArcGIS Server, either specific URL or stem
            matchAll = true to forward any request beginning with the url
            token = (optional) token to include for secured service
            dynamicToken = if true, gets token dynamically with username and
              password stored in this file.
            userName = the secured user's username
            password = the password for the username
            host = the machine name that is hosting the map service
    -->
    <serverUrl url="http://servername/ArcGIS/rest/services/Cadaster/CadasterLayerHalfTransparent/MapServer"
               matchAll="true"
               dynamicToken="true"
               host="servername"
               userName="UserName"
               password="ValidPassword"></serverUrl>
    <serverUrl url="http://www.google.com"
               matchAll="true"></serverUrl>
  </serverUrls>
  
</ProxyConfig>

I get no errors now. I'm still not getting the service that requires a token though....

Any ideas?

HaroldBostic

Hello,

what happens when you go to this url:

http://PathToYourProxy/prox.ashx?http://servername/ArcGIS/rest/services/Cadaster/CadasterLayerHalfTransparent/MapServer

and

hhttp://PathToYourProxy/prox.ashx?http://google.com

MatthewGerbrandt

Thanks again, Harold. Both of the links you suggested give me a blank web page. Going into �??View Source�?� gives the following code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META content="text/html; charset=windows-1252" http-equiv=Content-Type></HEAD>
<BODY></BODY></HTML>

No errors �?? no content.

MatthewGerbrandt

I just tried those links using FireFox and got the following error on the Google site:

XML Parsing Error: no element found
Location: http://servername/proxy.ashx?http://google.com
Line Number 1, Column 1:

I'm also getting an error in my proxy.config file when it's opened in Visual Studio. The error is:

The ProxyConfig element is not declared

SaurabhGupta

What is the version of VS and .Net framework you are working with ?
Where have you deployed your proxy files ? Do you have read/execute permissions to that folder ?

HaroldBostic

What happens when you go to:

http://PathToYourProxy/prox.ashx?http://www.google.com

I forgot the www in my last reply

MatthewGerbrandt

Harold - If I add the www, it works. I get the Google web site.

If I substitute www.google.com with my service's URL, I get

XML Parsing Error: no element found
Location: http://servername/proxy.ashx?http://Server.Name.com/ArcGIS/rest/services/cadaster/ServiceName/MapServer
Line Number 1, Column 1:

Is the problem that the server running the ArcGIS service has a domain name with more dot's in it than is usually expected?

For example, the domain name is: Server.Name.com
Instead of : ServerName.com

saur5784 - I'm running ASP.NET version 4.0.3xxxxxx

Thanks for your help and persistence, guys. I appreciate your help beyond words.

HaroldBostic

the domain name should not matter as my domain name has multiple dots.

do you have an unsecured service on that same server that you can test your proxy page with? If not, can you turn off ArcGISServer security and test that you can access your services?

After that, turn back on security and....

Can you go to your token url generator and ensure that the uname and pwd you are using can in fact generate a token for that service?

You can verify this by browsing to:
http://Server.Name.com/ArcGIS/rest/services/cadaster/ServiceName/MapServer?token=YourTokenGoesHere

if successful.....
The next step would to remove the dynamic token generation from your proxy config, and use the static one and try to access your service through your browser using the proxy as you did before.

Let me know if you need more clarification for any of the steps above.

MatthewGerbrandt

Alrighty... Thanks again, Harold!!

This code works:

<script type="text/javascript">
    dojo.require("esri.map");
    dojo.require("dijit.layout.ContentPane");
    dojo.require("dijit.layout.BorderContainer");
    var map;
    function Init() {

        esri.config.defaults.io.proxyUrl = "../proxy.ashx"; 
        dojo.style(dojo.byId("map"), { width: dojo.contentBox("map").w + "px", height: (esri.documentBox.h - dojo.contentBox("navTable").h - 40) + "px" });
        map = new esri.Map("map");
        
        var CountyDataLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://Server.Name2.com/ArcGIS/rest/services/Counties/MapServer");
        map.addLayer(CountyDataLayer);

        var RestrictedLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://Server.Name2.com/ArcGIS/rest/services/cadaster/ServiceName/MapServer?token=ZwBeUJKkl5L6bSitvEGgRy7hy52NmqBF8GIFCnB-7Lg.");
        map.addLayer(RestrictedLayer);
        
        
        var resizeTimer;
        dojo.connect(map, 'onLoad', function(theMap) {
            dojo.connect(dijit.byId('map'), 'resize', function() {
                clearTimeout(resizeTimer);
                resizeTimer = setTimeout(function() {
                    map.resize();
                    map.reposition();
                }, 500);
            });
        });
    }
    dojo.addOnLoad(Init);
</script>

Taking the token out of the JavaScript and putting it in the proxy.config file does not work:

<?xml version="1.0" encoding="utf-8" ?>
<ProxyConfig mustMatch="true">
  <serverUrls>
    <serverUrl url="http://Server.Name2.com/ArcGIS/rest/services/cadaster/ServiceName/MapServer"
               matchAll="true"
               token="ZwBeUJKkl5L6bSitvEGgRy7hy52NmqBF8GIFCnB-7Lg."></serverUrl>
  </serverUrls>
  
</ProxyConfig>

Any ideas?

SaurabhGupta

        esri.config.defaults.io.proxyUrl = "../proxy.ashx"; 
Change the URL to a complete server URL : http://servername/proxy.ashx
    <serverUrl url="http://Server.Name2.com/ArcGIS/rest/services/cadaster/ServiceName/MapServer"
  </serverUrls>  
Change the URL above to http://ServerName/ArcGIS/rest

See if above helps.

HaroldBostic

In that case you must generate the token using the ip address of the server in which the proxy resides rather than the url. i.e. the ip is the referer that should be used.

The new token should work inside the proxy

MatthewGerbrandt

Thanks again for your persistence, fellas! I've made the following changes but still, no luck...

<script type="text/javascript">
    dojo.require("esri.map");
    dojo.require("dijit.layout.ContentPane");
    dojo.require("dijit.layout.BorderContainer");
    var map;
    function Init() {

        esri.config.defaults.io.proxyUrl = "http://gisweb/proxy.ashx"; 
        dojo.style(dojo.byId("map"), { width: dojo.contentBox("map").w + "px", height: (esri.documentBox.h - dojo.contentBox("navTable").h - 40) + "px" });
        map = new esri.Map("map");
        
        var CountyDataLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://Server.Name2.com/ArcGIS/rest/services/Counties/MapServer");
        map.addLayer(CountyDataLayer);

        var RestrictedLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://Server.Name2.com/ArcGIS/rest/services/cadaster/AboriginalUseArea/MapServer");

        map.addLayer(RestrictedLayer);
        
    }
    dojo.addOnLoad(Init);
</script>

<?xml version="1.0" encoding="utf-8" ?>
<ProxyConfig mustMatch="true">
  <serverUrls>
    <serverUrl url="http://Server.Name2.com/ArcGIS/rest/"
               matchAll="true"
               host="10.10.10.51"
              token="ZwBeUJKkl5L6bSitvEGgRzZquMaWltg0GZY_xbGzVIA."></serverUrl>

  <serverUrl url="http://www.google.com"
               matchAll="true"></serverUrl>
  </serverUrls>
  
</ProxyConfig>

As far as the proxy.config file goes, I have also tried:

serverUrl url="http://Server.Name2.com/ArcGIS/rest/services"
serverUrl url="http://Server.Name2.com/ArcGIS/rest/services/cadaster"
serverUrl url="http://Server.Name2.com/ArcGIS/rest/services/cadaster/AboriginalUseArea"
serverUrl url="http://Server.Name2.com/ArcGIS/rest/services/cadaster/AboriginalUseArea/MapServer"
serverUrl url="http://10.10.10.51/ArcGIS/rest/services/AboriginalUseArea/"

Hello,

When you go to

http://Server.Name/ArcGIS/tokens/gettoken.html

And you get the screen like the attached, do you create the token using the ip address of Server.Name?

ArcGIS Token Service.png

HaroldBostic

Also, is this an externally facing server? If so, do you have a reverse proxy set up?

MatthewGerbrandt

Hello,

When you go to

http://Server.Name/ArcGIS/tokens/gettoken.html

And you get the screen like the attached, do you create the token using the ip address of Server.Name?

I use the server name, not the IP address. I also get the following error message:

Secure connection (SSL) required.

I do not have access to an SSL certificate. Is that a requirement? Sorry if that's a dumb question.

HaroldBostic

I have only gotten my proxy to work when I use the ip address of the server that the proxy resides I never gotten the proxy page to work with the server name

a potential resource
http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Configuring_the_Token_Service/00040000002w000000/GUID-BFE40BF6-0654-4334-9203-E62C4DD5B8F3/

How were you generating your token previously?

you can check out this link, where it shows you how to set the RequireSSL flag, you would set yours to false after reading about how this is only recommended in a dev environment

http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Configuring_the_Token_Service/00040000002w000000/GUID-BFE40BF6-0654-4334-9203-E62C4DD5B8F3/

MatthewGerbrandt

Also, is this an externally facing server? If so, do you have a reverse proxy set up?

Yes to both of those.

Disabled the requirement for SSL, by the way. I can now generate a token that's supposed to be good for 10 days. The problem is that the tokens being generated that way don't work. They're very long tokens and maybe that's the problem(?).

The only tokens that work are the ones generated the following way:
1) I go to the URL of one of the restricted services (http://Server.Name2.com/ArcGIS/rest/services/cadaster/AboriginalUseArea/MapServer).
2) I click on the link for viewing the ArcGIS JavaScript map.
3) I go to "View Source" and find the token that gets generated.

MatthewGerbrandt

Saurabh -

Is there any chance that you or someone at ESRI could check out this problem with your remote desktop tools? I've experimented with every possible combination of proxy.config settings using server names and IP addresses. The manually generated tokens and the proxy pages are not working.

I'm completely stumped and I really need the ability to display secured services in web maps. If there's anything you can do to help me, I'd sure appreciate it. Thanks a lot!

Thank you, Doug. I already have an open ticket for this issue. Saurabh has been working on it.

HaroldBostic

Hello, please ensure you are using the ip address that you get when ping'ing from outside your internal network. Ping your Server.Name.com url from outside your network.

If you try that and it still does not work, and ESRI does not help, let me know and I'll contact you offline.

Good Luck

MatthewGerbrandt

With help from Thang at ESRI, I was able to solve this problem. The first thing I had to do was to add a line of code to my web page:

<script type="text/javascript">
    dojo.require("esri.map");
    dojo.require("dijit.layout.ContentPane");
    dojo.require("dijit.layout.BorderContainer");
    var map;
    function Init() {

        esri.config.defaults.io.alwaysUseProxy = true;
        esri.config.defaults.io.proxyUrl = "http://WebServerName/proxy.ashx"; 
        dojo.style(dojo.byId("map"), { width: dojo.contentBox("map").w + "px", height: (esri.documentBox.h - dojo.contentBox("navTable").h - 40) + "px" });
        map = new esri.Map("map");
        
        var CountyDataLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://Server.Name/ArcGIS/rest/services/Counties/MapServer");
        map.addLayer(CountyDataLayer);

        var RestrictedLayer = new esri.layers.ArcGISDynamicMapServiceLayer("http://Server.Name/ArcGIS/rest/services/cadaster/ServiceName/MapServer");
        map.addLayer(RestrictedLayer);
        
        
        var resizeTimer;
        dojo.connect(map, 'onLoad', function(theMap) {
            dojo.connect(dijit.byId('map'), 'resize', function() {
                clearTimeout(resizeTimer);
                resizeTimer = setTimeout(function() {
                    map.resize();
                    map.reposition();
                }, 500);
            });
        });
    }
    dojo.addOnLoad(Init);
</script>

... and I used the following code in my proxy.config file:

<?xml version="1.0" encoding="utf-8" ?>
<!-- Proxy config is used to set the ArcGIS Server services that the proxy will forward to.        
        mustMatch: true to only proxy to sites listed, false to proxy to any site -->
<ProxyConfig mustMatch="true">
 <serverItems>
  
  <serverItem url="http://Server.Name"
     matchAll="true" tokenUrl="http://Server.Name/ArcGIS/tokens"
     username="MyUserName" password="MyPassword"
     timeout="5" />

 </serverItems>
</ProxyConfig>
