Problems with defined proxy page. What am I doing wrong?

ChrisSergent — Fri, 21 Nov 2014 21:18:34 GMT

I am trying to add proxy information to my site and my JavaScript, but it's returning errors. I don't need these urls to be secure. The following is my code for my application and my proxy.config file for the application published at: maps.decaturil.gov/decaturPrint

App Code:

<!DOCTYPE html>

<html>

<head>

<title>Create a Map</title>

<style>

html, body, #mapDiv

{

padding:0;

margin:0;

height:100%;

width:100%;

}

#feedback

{

background: #fff;

border: 2px solid #666;

border-radius: 5px;

bottom: 20px;

color: #666;

font-family: arial;

height: auto;

left: 20px;

margin: 5px;

padding: 10px;

position: absolute;

width: 300px;

z-index: 40;

}

#feedback a

{

border-bottom: 1px solid #888;

color: #666;

text-decoration: none;

}

#feedback a:hover, #feedback a:active, #feedback a:visited {

border: none;

color: #666;

text-decoration: none;

}

#note

{

padding: 0 0 10px 0;

}

#info

{

padding: 10px 0 0 0;

}

</style>

var map;

require(["esri/map", "esri/config",

"esri/arcgis/utils",

"esri/dijit/Print",

"esri/geometry/Extent",

"esri/layers/ArcGISDynamicMapServiceLayer",

"esri/layers/ArcGISTiledMapServiceLayer",

"esri/layers/FeatureLayer",

"esri/tasks/GeometryService",

"dojo/_base/array",

"dojo/dom",

"dojo/on",

"dojo/parser",

"dijit/layout/BorderContainer",

"dojo/domReady!"], function (Map, esriConfig, arcgisutils, Print, Extent,

ArcGISDynamicMapServiceLayer, ArcGISTiledMapServiceLayer,

FeatureLayer, GeometryService, PrintTemplate, arrayUtils, dom, on, parser

) {

/* The proxy comes before all references to web services */

/* Files required for security are proxy.config, web.config and proxy.ashx

- set security in Manager to Private, available to selected users and select Allow access to all users who are logged in

(Roles are not required)

The proxy section is defined on the ESRI sample. I have included it as

part of the documentation reads that the measuring will not work.

I thought that might be important.

// Proxy Definition Begin

//identify proxy page to use if the toJson payload to the geometry service is greater than 2000 characters.

//If this null or not available the project and lengths operation will not work.

// Otherwise it will do a http post to the proxy.

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

esriConfig.defaults.io.alwaysUseProxy = true;

// Proxy Definition End

// set custom extent

var initialExtent = new Extent({

"xmin": 777229.03,

"ymin": 1133467.92,

"xmax": 848340.14,

"ymax": 1185634.58,

"spatialReference": {

"wkid": 3435

}

});

// create map and set slider style to small

var map = new arcgisutils.createMap("mapDiv", {

showAttribution: false,

sliderStyle: "small",

extent: initialExtent

});

// add imagery

var tiled = new ArcGISTiledMapServiceLayer("http://maps.decaturil.gov/arcgis/rest/services/Aerial_2014_Tiled/MapServer");

map.addLayer(tiled);

// set operational layers

var operationalLayer = new ArcGISDynamicMapServiceLayer("http://maps.decaturil.gov/arcgis/rest/services/Public/InternetVector/MapServer", { "opacity": 0.5 });

// add operational layers

map.addLayer(operationalLayer);

// declare geometry service

esriConfig.defaults.geometryService = new GeometryService("http://maps.decaturil.gov/arcgis/rest/services/Utilities/Geometry/GeometryServer");

}

);

</script>

</head>

</body>

</html>

proxy.config file

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

<ProxyConfig allowedReferers="*"

mustMatch="false">

<!-- 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

password stored in web.config file's appSettings section.

-->

<serverUrl url="http://maps.decaturil.gov/arcgis/rest/services"

</serverUrls>

</ProxyConfig>

Hi Chris,

If the proxy.ashx file is within the same folder as your application, your proxy should work. If it's not, you will need to update the path to the proxy.ashx file. For example:

esriConfig.defaults.io.proxyUrl = "http://<server name>/proxy/proxy.ashx";

In the above, I'm specifying to read the proxy.ashx in a folder called 'proxy' on a web server.

I believe you are receiving errors because you are trying to construct a map using the esri.arcgis.utils class, but you are not working with a web map. Try using the Map class. Ex:

My proxy was right. The error was the esri.arcgis.utils. Thanks.
