POST request with application/json body

[HalfdanJ]

Am I just missing it, or does the postRequest object not support post request where i supply the raw body instead of through a form? I see the PUT request has a setPutBuffer that seems to be what I need, but that is not implemented in POST.

Ha, I'm literally working on that right this moment. I'll ping back here in a second ...

[HalfdanJ]

Convenient 👍 well, learned a lot of POCO on the way :)

[bakercp]

Good. I'm pushing it to develop momentarily ...

[bakercp]

I just build a nice client for Google Cloud Vision (authentication was the hardest part, but I got JSON Web tokens and oauth2 in ofxHTTP now) and a few other services with it, which I'll also push to develop.

[bakercp]

OK, check out the develop branch. You may need to make sure you're using the develop branch of the dependencies. Once you get it, check out the JSON example.

[HalfdanJ]

Heh, Cloud Vision was also the thing I was working on :) Thanks for the push! Ill take a look at it

[HalfdanJ]

I'm using your post example, trying to post JSON to https://vision.googleapis.com/v1/images:annotate?key=<KEY>

isSuccess() returns false, but no error is printed. I beleive maybe its because i miss Content-Type: application/json in the header?

[bakercp]

Yeah, the post example won't work -- you have to use the json example -- which uses an ofxHTTP::JSONRequest, rather than an ofxHTTP::PostRequest underneath.

[HalfdanJ]

Sorry, also what i meant.. I use the code from the link

[bakercp]

Hm ... let me take a look.

[HalfdanJ]

I dont know if its beacuse im missing a commit in a dependency. I couldn't find any develop branch on the other repos.

[bakercp]

Can you ignore the issuccess and see what data is printed back to you? Also, check the response for error codes ... and also make sure you clean your project :)

[HalfdanJ]

Found it , invalid argument.. Will look at it (tomorrow)

[bakercp]

Cool! Keep me posted and maybe I'll have my ofxCloudPlatform public tomorrow ...

[bakercp]

Hey, found your bug and fixed it here: 9a4a90ae0421098f4300da96acd1aa21dd5191e2

[HalfdanJ]

Worked, thanks!

[bakercp]

By the way @HalfdanJ, you can check out a working example here https://github.com/bakercp/ofxCloudPlatform.

Hey @bakercp I am trying to make a POST with a binary file on the body, like @HalfdanJ says. (like PUT's method has) I want to upload files to Firebase Storage from OF. The working post format I used in POSTMAN is working:

[moebiussurfing]

nice! solved. :) it worked like that:

std::string url = "https://firebasestorage.googleapis.com/v0/b/xxxxxx.appspot.com/o?uploadType=media&name=myFolder/myPictureObjectName";

ofx::HTTP::Client client;
ofx::HTTP::Context context;
ofx::HTTP::PostRequest postRequest(url, Poco::Net::HTTPMessage::HTTP_1_1);

postRequest.setContentType("image/png");
postRequest.addFormFile("", "filename.png");
try
{
auto response = client.execute(context, postRequest);
...
}

[moebiussurfing]

hmm.... sorry @bakercp for still bothering you with this, but I think sometimes it's useful to have some of your PUT methods (setPutFile, setPutBuffer...) on a POST request. Now I am trying to make a POST to the Firebase database to create a new object like this:

Saving Lists of Data

To generate a unique, timestamp-based key for every child added to a Firebase database reference we can send a POST request. For our users path, it made sense to define our own keys since each user has a unique username. But when users add blog posts to the app, we'll use a POST request to auto-generate a key for each blog post:

curl -X POST -d '{ "author": "alanisawesome", "title": "The Turing Machine" }' 'https://docs-examples.firebaseio.com/rest/saving-data/fireblog/posts.json' Our posts path now has the following data:

{ "posts": { "-JSOpn9ZC54A4P4RoqVa": { "author": "alanisawesome", "title": "The Turing Machine" } } } Notice that the key -JSOpn9ZC54A4P4RoqVa was automatically generated for us because we used a POST request. A successful request will be indicated by a 200 OK HTTP status code, and the response will contain the key of the new data that was added:

{"name":"-JSOpn9ZC54A4P4RoqVa"}

I am trying like this, but I am getting a 400 Bad Request (uncomplete message) reply:

std::string url = "https://xxxxxx.firebaseio.com/seeds.json";
ofx::HTTP::Client client;
ofx::HTTP::Context context;
ofx::HTTP::PostRequest postRequest(url, Poco::Net::HTTPMessage::HTTP_1_1);

postRequest.setContentType("text/javascript");
postRequest.addFormFile("", "file.json");
...
