Good morning.
I am implementing a proxy to my application so that the user does not have to enter login/password every time he wants to enter the application.
I have the application downloaded and implemented on my local server.
I have checked that the webmap is shared with the Organization as well as the layers it has published.
I am using Xammp's Apache server and the proxy chosen was the PHP version offered by ESRI.
GitHub - Esri/resource-proxy: Proxy files for DotNet, Java and PHP.
First I configured the proxy.config:
<?xml version="1.0" encoding="utf-8" ?>
<ProxyConfig allowedReferers="*"
logFile="proxy_log.log"
mustMatch="true">
<serverUrls>
<serverUrl url="https:
username="USER"
password="PASSWORD"
matchAll="true"/>
<serverUrl url="http:
matchAll="true"/>
</serverUrls>
</ProxyConfig>
Second I configured the config.json:
"wabVersion": "2.12",
"isWebTier": false,
"httpProxy": {
"useProxy": true,
"alwaysUseProxy": false,
"url": "PHP/proxy.php?",
"rules": [{
"urlPrefix": "http://MY_ORGANIZATION.maps.arcgis.com/",
"proxyUrl": "PHP/proxy.php?"
}]
The application loads correctly without asking for username/password.
However it does not load the features.

Services that are not displayed return an error of the type:
{"error":{"code":499,"message":"Token Required","messageCode":"GWM_0003","details":["Token Required"]}}
I don't know if the mistake can come from:
1) I haven't introduced any service in the "proxy.config" so that it passes with the proxy and the features are displayed.
2) When entering username/password I have to change another parameter that I don't know what it can be.
Any idea? Thank you very much in advance
