4.7 - I need to add "http://localhost:44300" into CORS policy for debug my project.

TubaKumbara — Mon, 14 May 2018 06:18:09 GMT

Hello.

I'm developing sceneView application and i can't see basemaps when i debugging my project on localhost (pressing F5). Because CORS policy blocking my localhost. But i see no error when i published my project.

I tried to add

esriConfig.request.corsDetection = false;

But doesn't worked.

AccessTo image at "https://myproxyserver/resource-proxy/proxy.ashx?http://myserver.com/myservice/3/5/1.jpg" from origin "https://localhost:44300" has been blocked by CORS policy: No "Access-Contol-Allow-Origin" header is present on the requested ressource. Origin "https://localhost:44300" is therefore not allowed access

Thanks inadvance.

Tuba,

You really need to get out of the habit of using localhost. You should use your machine name instead and then make sure you have added your machine name to the proxy.config serverUrls.

thanks for the answer.

ye you're right.

I tried to add below codes into my javascript file

urlUtils.addProxyRule ({ urlPrefix: "https://mymachinename", proxyUrl: "https:proxrserver/proxy.ashx"});

and into proxy.config file

<serverUrl url="https://mymachinename" matchAll="true" />

and i changed to Project URL from VB.NET Project Properties with "https://mymachinename"

doesn't worked. same error.

Tuba,

You have to add the port number to the url or else it is seen as a different server. https://mymachinename:44300 needs to be added to the proxy rule and proxy.config

Hi Robert,

i've defined 44300 port as https from IIS manager. mymachinename is my local IIS name not different server.

JS file

urlUtils.addProxyRule ({ urlPrefix: "https://mymachinename:44300", proxyUrl: "https:proxrserver/proxy.ashx"});

proxy.config file

<serverUrl url="https://mymachinename:44300" matchAll="true" />

still getting same error. I just seeing empty globe in sceneview.

RobertScheitlin__GISP — Tue, 15 May 2018 12:45:15 GMT

Tuba,

Can you post the error again now that you have made these changes? I just can not understand how you would be getting the same exact error now.

Hello,

I'm getting this error on program startup (with sceneview). I'm seeing only white sceneview. "MyCustomTileMap" is my basemap and i can access from MapView without error. This error occurs when i switch to 3D.

Access to image at "http://myproxyserver/mydir/proxy.ashx?http://mymapserver/Maps/MyCustomTileMap/1/2/3.jpg" from Origin "http://mymachinename" has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin "http://mymachinename" is therefore not allowed access.

Thanks inadvance.

Tuba,

Notice that the error is using the http protocol not https you added to the proxy. Also the error does not show a port number.

TubaKumbara — Tue, 15 May 2018 13:49:11 GMT

sorry my bad. all adresses started with https not http. just written wrong here. I tried to run my application with 44300 portnumber and added into proxy.config with port. Still getting same error.

RobertScheitlin__GISP — Tue, 15 May 2018 13:56:09 GMT

Tuba,

So are you also forgetting to add the port number when you are editing the error message to post here?.. You should add the serverURL with http and https and the port and without the port for testing in the proxy.config and proxy rules.

Re: 4.7 - I need to add "http://localhost:44300" into CORS policy for debug my project.

TubaKumbara — Tue, 15 May 2018 14:08:08 GMT

Yes Exactly

My machine name is "goldone".

proxy.config

<serverUrl URL="http://goldone" matchAll="true" />
<serverUrl URL="http://goldone:44300" matchAll="true" />
<serverUrl URL="https://goldone" matchAll="true" />
<serverUrl URL="https://goldone:44300" matchAll="true" />

JS file

urlUtils.addProxyRule ({ urlPrefix: "http://goldone", proxyUrl: "https://proxrserver/proxy.ashx"});
urlUtils.addProxyRule ({ urlPrefix: "http://goldone:44300", proxyUrl: "https://proxrserver/proxy.ashx"});
urlUtils.addProxyRule ({ urlPrefix: "https://goldone", proxyUrl: "https://proxrserver/proxy.ashx"});
urlUtils.addProxyRule ({ urlPrefix: "https://goldone:44300", proxyUrl: "https://proxrserver/proxy.ashx"});

have i do something another this

My application running from VB.NET (with F5) starting as "https://goldone:44300"

RobertScheitlin__GISP — Tue, 15 May 2018 14:12:02 GMT

Tuba, that looks good for the proxy rules now in the proxy.config you need to do the same for the serverURLs

TubaKumbara — Tue, 15 May 2018 14:15:10 GMT

Robert,

This is my proxy.config file which in same directory with proxy.ashx

<serverUrl url="http://goldone" matchAll="true" />
<serverUrl url="http://goldone:44300" matchAll="true" />
<serverUrl url="https://goldone" matchAll="true" />
<serverUrl url="https://goldone:44300" matchAll="true" />

RobertScheitlin__GISP — Tue, 15 May 2018 14:18:12 GMT

Then there should be no reason for you getting that error then. I am not sure what to tell you.

TubaKumbara — Tue, 15 May 2018 14:21:15 GMT

Robert, Thanks for your interests. I know you want to help but i can't to say anything else. I can't debug my codes,

Same sceneview running good when i publish my application to another server. But this is hard to debug from developer console.

I personally do not use Visual Studio for development. I use Atom.io for my js development IDE and just do my debugging in Google Chrome.

Thank you again for all help.
