We started to use ASP.NET CORE with the latest Esri Javascript fw (4.x) to build custom apps .

This means the current implementation of the proxy page as request handler which is no more supported in ASP.NET CORE and replaced by middleware, won't work .

Did you guys think about the change in Microsoft space ( classic vs CORE) and come up with a newer version of the proxy that works as a middleware ? If so when do you think that you can provide customers with a version that works on the ASP.NET CORE framework ?

Thanks,

Using Federated Portal 10.3 with DotNet proxy on application authentication, we are getting an error code 498 when trying to access a secure map service that was created with the same account as the registered app. I verified that the clientId and clientSecret (appId and appSecret) are valid. ArcGIS and Portal are on the same server. In case it is a factor, the web adapter was changed from "arcgis" to "portal", so logging in to Portal and the oAuth path start with https://myservername/portal rather than https://myservername/arcgis, but the map services still reference https://myservername/arcgis.

Error: dojo.io.script.jsonp_dojoIoScript1._jsonpCallback({"error":{"code":498,"message":"Invalid Token","details":[]}});

proxy.config: <?xml version="1.0" encoding="utf-8" ?><br/><ProxyConfig allowedReferers="*"<br/>             mustMatch="true"><br/>    <serverUrls><br/>        <serverUrl url="https://myservername"<br/>            clientId="xxx"<br/>            clientSecret="xxx"<br/>            oauth2Endpoint="https://myservername/portal/sharing/rest/oauth2/"<br/>            matchAll="true"/><br/>    </serverUrls><br/></ProxyConfig>

Is there a way to enable detailed logging or debugging? I'm not familiar with ASP (it's the only ESRI proxy format I can use on our server). The logFile option doesn't provide detailed logging.

Considering the growth of node.js and pervasiveness of javascript, what about to build a proxy page that executes in node.js?

This would remove the requirement for a php, or java, or .net server engine for a full-stack javascript programmer.

Downloaded the ZIP, copied PHP folder the Apache web server folder, made sure read/write permissions were set where appropriate. Following steps in PHP README.md file where it states to test the proxy was installed correctly by typing in

http://[yourmachine]/PHP/proxy.php?http://services.arcgisonline.com/ArcGIS/rest/services/?f=pjson

results in an error "{"error":{"code":412,"details":["Detected malformed 'logFile' in configuration. Make sure this app has write permissions to specified log file in configuration. The server does not meet one of the preconditions that the requester put on the request."],"message":"Proxy failed due to configuration error."}}"

The error goes away as soon as I manually create the proxy_log.log file.

I know that proxy should only work with token-based arcgis server, but is there any way to allow the url for arcgis server that is not set for token based but window authentication only

This came about when trying to use the most recent PHP proxy against the basic directions Javascript sample. Swapping out the proxy file with the PHP one on my machine (OSX Mavericks, and then Yosemite) and adding my credentials to the config file. When running the same everytime i would get an "Undefined token error" and after checking the response back from the route service via the proxy, it was always truncated, "dojo.io.script.jsonp_dojoIoScript1._jsonpCallback({"currentVersion":10.3,"layerName":"Route_World","layerType":"esriNAServerRouteLayer","impedance":"TravelTime","restrictions":["Avoid Unpaved Roads","Avoid "

Notice that the full JSON callback is cut off. To narrow down if it was machine specific, I configured a clean Apache instance on my personal Macbook running Yosemite (older hardware model, via 2012) and got the same exact error message when trying to run this sample.

Spoke to @phpmaps and he had an idea what was going on. Created this issue so that the fix he implemented in an updated PHP could be merged into this repo.

I'm seeing a problem whereby passing a query to the Esri Geoportal Server's REST API, via the Esri Resource Proxy, is causing users to be logged out of the Geoportal.

I can reproduce the problem like this:

• install the Esri Geoportal Server on Windows using IIS
• install the Esri Resource Proxy on the same machine
• log in to the Geoportal (eg http://localhost:8080/geoportal/catalog/identity/login.page)
• in a new tab in the same browser, send a query to the Geoportal REST API via the Esri proxy (eg http://localhost/PHP/proxy.php?http://localhost:8080/geoportal/rest/find/document?f=pjson)
• switch back to the Geoportal tab, refresh the page, and note that the user is now logged out

This error does not occur for me using the sandbox Geoportal at http://gptogc.esri.com/geoportal/catalog/main/home.page (you can test it at http://stephenlead.com/esri-proxy/PHP/proxy.php?http://gptogc.esri.com/geoportal/rest/find/document?&max=10&rid=local&f=pjson)

Do you know why this is occurring? Is the problem occurring because the proxy is on the same machine as the Geoportal Server? Are there any known workarounds?

Thanks, Steve

(ping @mhogeweg)

(“https://github.com/Esri/resource-proxy”   link to download the proxy). Once we setup up the proxy and pass the first url http://localhostDotNet/proxy.ashx?ping for test we get the following message which shows the configuration is ok.

In the second step we need to pass the url through the proxy so we pass the following url

This error message shows the proxy has not been setup properly because of where the url is not able to pass through the proxy file.

Thus far I have been able to configure the proxy.php system so it works on its own. Like testing the configuration at  http://freshsoftware.net/usps/eddm/sample_api/proxy/proxy-verification.php.

I can also test the argis json response by running http://freshsoftware.net/usps/eddm/sample_api/proxy/proxy.php?http://services.arcgisonline.com/ArcGIS/rest/services/?f=pjson.

But I have not been able to get the SAMPLE API to work with the the PHP Proxy. I even tried editing geoprocessing.js by editing the line 41 so it says esriConfig.defaults.io.proxyUrl = "/proxy/proxy.php"; But the sample_api still does not work. Try it your self at http://freshsoftware.net/usps/eddm/sample_api/?secret_key=MTI1ZjVyN3JBNTY2dDJlcjE1d2tyNTQ0dWprNDhraklXUzZuJXdrZGprSkg=.

How do I get the SAMPLE API to work with PROXY.PHP?

DotNet proxy client return GET methods in IE only but in other browsers POST is there, for IE V11 I keep getting SCRIPT1002: Syntax error, any one can help please

Any idea what's going on here?

When I ping the proxy URL, it displays OK But in practice when I try to visit https://mydomain.com/proxy/proxy.php?https://orgurl.maps.arcgis.com/sharing/rest/portals/self?f=json it returns a 500 error.

I'm a novice at Linux admin issues so I could use some advice on how to install the PHP version of the proxy on an AWS EC2 (Amazon Linux 2) machine.

This is possibly related to https://github.com/Esri/resource-proxy/issues/372 (?)

• I've configured a new EC2 instance and installed LAMP
• I've verified that PHP is working
• I installed the esri-resource-proxy using git clone into /var/www/html/resource-proxy/ and am working in the PHP directory
• the proxy verification script shows that everything should be OK (except that the config file is visible)
• but the proxy fails so presumably there's something else going wrong

I note that the proxy_log.log file is never created although the directory is writeable. Here is the directory listing (these files are unchanged after the git clone):

I added the following to /etc/httpd/conf/httpd.conf:

<IfModule php5_module>
    AddType application/x-httpd-php .php
    AddType application/x-httpd-php-source .phps

    <IfModule dir_module>
        DirectoryIndex index.html index.php
    </IfModule>
</IfModule>

Thanks for any advice as to why the PHP proxy isn't working correctly.

Hi,

I try ..../proxy.ashx?https://SERVER/arcgis/rest/services/WMTS/orthophoto_2019/MapServer?request=GetCapabilities&service=WMTS&version=1.0.0 but I have this error :

What the problem ? {"error": {"code": 500,"message":"La demande a été abandonnée : Impossible de créer un canal sécurisé SSL/TLS. https://SERVER/arcgis/rest/services/WMTS/orthophoto_2019/MapServer?request=GetCapabilities&service=WMTS&version=1.0.0"}}

Thanks for your help

We have an application that is configured to use the .net proxy. We are seeing some of the preliminary calls fail to use the proxy, which results in them giving an error. We are using the proxy for authentication, but also to map to an internal server from a public load balancer. There are two calls that are not using the proxy, and when on an external server they return failures. How can we ensure that these calls utilize the proxy correctly?

This PR supersedes https://github.com/Esri/resource-proxy/pull/556. It includes updates to place the repository in deprecation mode.

Browser and web server technology has advanced since this repo was originally created, and there are significantly better ways to manage secure geospatial services today. Some examples are documented in the README, such as CORS, API keys, as well as the ability provide fine-grained access management and secure services through ArcGIS Online and ArcGIS Enterprise.
