Not found because of proxy error: Error: socket hang up #94

Closed jromerob closed 6 years ago

jromerob commented 6 years ago

I'm trying to get indications of a walk route quering the Cartociudad service. The service url is ok and responds with a JSON with all the indications.

Testing the service URL in my navigator the result is ok but in my Angular app when i try http.get("http://127.0.0.1:8123/http://www.cartociudad.es/services/api/route?orig=40.44184877149766,-3.5748567877248845&dest=41.36999441400242,2.1469160601647803&locale=es&vehicle=WALK") the result is a 404 NOT FOUND. Response._body is "Not found because of proxy error: Error: socket hang up"

Trying with other proxy the result is OK. Any ideas ?

Thanks.

Current proxy.js var host = process.env.PORT ? '0.0.0.0' : '127.0.0.1'; var port = process.env.PORT || 8123;

var cors_proxy = require('cors-anywhere'); cors_proxy.createServer({ originWhitelist: [], // permite todos los orígenes requireHeader: [], removeHeaders: ['cookie', 'cookie2'], setHeaders : { "x-powered-by": "CORS Anywhere" } }).listen(port, host, function() { console.log('Ejecutando proxy en ' + host + ':' + port); });

Trying with other proxy the result is OK.

Is this proxy also running on localhost?

jromerob commented 6 years ago

Yes, the proxy is on localhost (127.0.0.1:8123).

This is the Chrome console output:

Rob--W commented 6 years ago

Not CORS Anywhere, the other proxy that is working according to you. I am asking in order to determine whether the issue is specific to CORS Anywhere, or specific to your local setup (e.g. your IP is blocked by that other site, or your firewall has blocked outbound connections).

jromerob commented 6 years ago

Oh, sorry !. No, the other proxy isn't on localhost. But CORS Anywhere is working ok in other request in the same app. the error occurs only in that request.

This is a right request made by the same app throught CORS anywhere running at localhost image

Rob--W commented 6 years ago

When you use another program to send the request to the destination, with the same request headers (e.g. curl), does the request succeed?

jromerob commented 6 years ago

Curl works right:

curl "http://127.0.0.1:8123/http://www.cartociudad.es/services/api/route?orig=40.44184877149766,-3.5748567877248845&dest=41.36999441400242,2.1469160601647803&locale=es&vehicle=WALK"

Hi i think i found the problem:

I'm loading the app on localhost and the proxy on 127.0.0.1, in this case fails the request image

if load the app over 127.0.0.1 the request works !! image

Is localhost resolving to 127.0.0.1 ?

Curl works right:

Can you use exactly the same curl command as the browser (in the devtools you can right-click on a request row and click to copy as a curl command). Then repeatedly issue the request and remove headers at each step until you found which request header results in a difference of how a request is handled.
