Hi everyone

I’ve searched the forum but can’t find anything similar with an answer so thought I’d try a new post.

I’ve set up DF 2.12 and a remote HTTP service to Stripe. This works perfectly when I call the DF service endpoint via Postman or via Curl on the command line, e.g.

```
curl -X GET \
  'https://api.mydfserver.com/api/v2/stripesandbox/accounts?_dc=1524129954370&offset=1&start=0&limit=25' \
  -H 'X-DreamFactory-API-Key: myDFkey'

```

Then it correctly returns accounts from Stripe in JSON format.

If I try the same GET using Ajax (plain XMLHttpRequest or JQuery) then I see the request fire in Chrome Tools, it returns 200 OK, but the response is empty / blank.

CORS are set to \* - no errors at all. I’ve tried from localhost and also from a web server. Curl on the web server works fine too.

I should say that normal calls to DF work fine from Ajax e.g. I can access my MySQL table through \_table endpoint without issues, it’s just when I try and use the HTTP service.

Any ideas if this is a bug or if there is some other restriction with HTTP service?

Thanks

Doing some digging about I can see that if I intercept the “return $response” in /opt/bitnami/apps/dreamfactory/htdocs/vendor/dreamfactory/df-rws/src/Services/RemoteWeb.php processRequest method e.g. print\_r($response); exit; instead of returning, then I see the output in the Chrome console for the Ajax request.

Seems like something along the way is deleting the response body.

Will do some more digging

Hi Tim,

This is most curious. Can you enable debugging in the .env file (found in the htdocs folder) and change the APP\_LEVEL\_LOG=debug and then look at the logs and see if you see anything weird when you hit the endpoint via AJAX? If you hit the endpoint in the admin interface in the API Docs tab, is it rendering a 200 with the proper JSON?

Thanks,

Erik

Hi Erik

Thanks for getting back to me. After enabling APP\_LOG\_LEVEL=debug I see the following in dreamfactory.log when I trigger the AJAX request (Chrome tools shows 200 OK on the GET):

> [2018-04-20 12:13:33] local.INFO: [REQUEST] {“API Version”:“2.0”,“Method”:“GET”,“Service”:“stripesandbox”,“Resource”:“accounts”,“Requestor”:1}

> [2018-04-20 12:13:34] local.INFO: [RESPONSE] {“Status Code”:200,“Content-Type”:“application/json”}

I go to API Docs and select the service, it says “The service ‘stripesandbox’ has no API docs.”

Thanks  
Tim

Thanks Tim for the logs!

With regard to the API Docs, I had not had enough coffee. There wouldn’t be anything that showed up as there is not a native Swagger 3.0 service definition attached to the stripe service.

Can you try this:

[https://api.mydfserver.com/test\_rest.html](https://api.mydfserver.com/test_rest.html)

Then use your basic auth creds (your login to your df instance) and see if you can see the output when you access the service? This is a lightweight, stripped down version of your df instance (no angular front end) that works like Postman or Insomnia.

Thanks,

Erik

OK now this is interesting. I get the following JSON error response when using test\_rest (standalone Postman still works fine), and the response to indicate a 400 error from Stripe due to invalid parameters, but I am not sure where these are coming from. I am not including any params in my original GET:

```

OK I added \_ to the exclude list and now I just get an empty “Output” response from test\_rest, which is the same as I get when calling the endpoint via Ajax in the browser ☹ At least it is consistent 🙂

</div>

If I edit ./htdocs/vendor/dreamfactory/df-rws/src/Services/RemoteWeb.php and add a print\_r around line 421 e.g.

```
 Log::debug('Outbound HTTP request: ' . $this->action . ': ' . $url);
        Curl::setDecodeToArray(true);
        $result = Curl::request($this->action, $url, $data, $options);
        $resultHeaders = Curl::getLastResponseHeaders();
print_r($result);
exit;

```

then I can see the response from the Stripe endpoint in test-rest output section, so the code path to call Stripe is working. It’s just getting eaten up somewhere along the way from DF back to the browser. The response is valid JSON.

Thanks, I appreciate that. Is there another way I could wrap the Stripe API, perhaps using custom script and curl ?

I believe [this problem](https://community.dreamfactory.com/t/prevent-dreamfactory-from-double-encoding-url-parameters/4835) because I tried the service with postman simple url (not encoded) ,it works but when i paste the url that is made by ajax call …bhammm it does not work.
