problem with setting up proxy

Mariagomez1 — Fri, 22 Apr 2016 13:20:10 GMT

I just want to load a map service using proxy. I read all of instructions for setting up proxy and proxy set up problems that are asked but I could not solve my problem.

I did following steps:

1- I downloaded the proxy files for .Net. They are proxy.ashx and proxy.config that I put them in a folder named proxy on

my server under inetpub/wwwroot.

2- I edited proxy.config file to contain the paths to my local services.

<?xml version="1.0" encoding="utf-8" ?>

<ProxyConfig allowedReferers="*"

mustMatch="true">

<serverUrl url="http://localhost:6080.com"

matchAll="true"/>

</serverUrls>

</ProxyConfig>

First question: I changed url="http://services.arcgisonline.com" to url="http://localhost:6080.com". is it right?

3- I went into IIS Manager and create an application from proxy folder.

My index html code in inetpub/wwwroot:

<!DOCTYPE html>

<html>

<head>

<title>Create Map and add a dynamic layer</title>

<style>

html, body, #mapDiv{

padding: 0;

margin: 0;

height: 100%;

}

</style>

var map;

require([

"esri/map",

"esri/config",

"esri/layers/ArcGISDynamicMapServiceLayer",

"esri/geometry/Extent",

"esri/layers/ImageParameters",

], function (

Map,esriConfig, ArcGISDynamicMapServiceLayer,Extent, ImageParameters) {

esriConfig.defaults.io.proxyUrl = "./proxy/proxy.ashx";

esriConfig.defaults.io.alwaysUseProxy = true;

var bounds = new Extent({

"xmin":817962,

"ymin":-187036,

"xmax":1566109,

"ymax":785554,

"spatialReference":{"wkid":32640}

});

map = new Map("mapDiv", {

extent: bounds

});

var dynamicMapServiceLayer = new ArcGISDynamicMapServiceLayer("http://localhost:6080/arcgis/rest/services /sdeMXD/MapServer", {

"opacity" : 0.5

});

map.addLayer(dynamicMapServiceLayer);

});

</script>

</head>

<body>

</body>

</html>

This is the error in firebug:

GET http://localhost:6080/arcgis/rest/info?f=json

200 OK

51ms

init.js (line 152)

SyntaxError: expected expression, got '<' proxy.a...allback (line 1)

<%@ WebHandler Language="C#" class="proxy" %>

init.js (line 1488)

I spend long time but i could not find out what is wrong with it. I really appreciate it if anybody help me.Thanks in advance

Maria,

To start, No

<serverUrl url="http://localhost:6080.com"

matchAll="true"/>

Is not correct. It needs to be:

<serverUrl url="http://localhost:6080"

matchAll="true"/>

In step 3 did you make sure you paid attention to this note

Make sure the "Application pool" is at least 4.0.

Did you test your proxy using http://localhost/proxy/proxy.ashx?ping

This line in your code

esriConfig.defaults.io.proxyUrl = "./proxy/proxy.ashx";

Would mean that this html doc is in some folder inside of the inetpub/wwwroot folder (because ./ means go up to the parent folder).

Thanks Robert for your quick answer.

1- I changed url="http://localhost:6080.com" to url="http://localhost:6080"

2- I set application pool as ASP.NET V4.0 - is it right?

3- I did not know how to test proxy (http://localhost/proxy/proxy.ashx?ping)

I just copy the url in browser and it gave me following answer:

{ "Proxy Version": "1.1.0", "Configuration File": "OK", "Log File": "Not Exist/Readable"}

Is proxy working correctly?

4- yes my html file ( index.html) is in inetpub/wwwroot so its directory is inetpub/wwwroot /index.html

and proxy directory is inetpub/wwwroot /proxy/proxy.ashx

Still I have the mentioned errors.. although I corrected step 1..

Maria,

Good
Yes that is correct
Yes it is working correct
There is an issue here still. Change you code to esriConfig.defaults.io.proxyUrl = "proxy/proxy.ashx";

Dear Robert , I changed esriConfig.defaults.io.proxyUrl = "./proxy/proxy.ashx"; to

esriConfig.defaults.io.proxyUrl = "proxy/proxy.ashx"; but still I have the mentioned errors. What is wrong with it?

Maria,

When I switch your code to the esri hosted JS API (not your local one) and point to a map service on my machine your code runs fine. So it could be that you are having issue with your Local copy of the API. It is really hard for me to tell.

I changed my JS API from local to esri hosted one but still I have the mentioned errors in firefox but

in chrome browser i face with this error:

proxy.ashx?http://localhost:6080/arcgis/rest/services/sdeMXD/MapServer?f=json&dpi=96&transparent=tr…:1

Uncaught SyntaxError: Unexpected token <

Maria,

That tells me that you have a syntax error in your proxy.config. Can you attach your proxy.config?

Re: problem with setting up proxy

Mariagomez1 — Sat, 23 Apr 2016 14:45:31 GMT

I could not find attachment of files so i took a picture from it, and also i pasted its codes here :

<?xml version="1.0" encoding="utf-8" ?>

<ProxyConfig allowedReferers="*"

mustMatch="true">

<serverUrl url="http://localhost:6080"

matchAll="true"/>

</serverUrls>

</ProxyConfig>

Maria,

To attach files in GeoNet you need to click the "Use advanced editor" link in the upper right corner of the reply window. This option is not available from inside the inbox so you will have to open the thread and then you will see this option. Once you click the "Use advanced editor" then in the lower right corner of the reply window there will be an attach link.

Nothing jumps out as wrong with your proxy.config. but try replacing with this one anyway.

When you are trying to bring up your page you are using

http://localhost/index.html

Right? Not http://localhost:6080/index.html?

Re: problem with setting up proxy

Mariagomez1 — Sat, 23 Apr 2016 20:16:05 GMT

work fine with http://localhost/index.html .. thanks clever Robert.
