Dart POST JSON to Google App Engine via EndPoints

Question

Does anyone know why I keep getting Error 400 Parse Error when POST to App Engine? My JSON is fine. I have JSON.encoded it. Anyone run into these issues before???

This is my HTTPRequest code.

sendData = JSON.encode(data);

_httpRequest = new HttpRequest()
        ..open(method, url)
        ..setRequestHeader("Authorization", "Bearer " + tokenKey)
        ..onLoadEnd.listen((e) => _loadEnd(_httpRequest))
        ..send(sendData);

Have you checked the comments on http://stackoverflow.com/questions/19261862/this-api-does-not-support-parsing-form-encoded-input — Günter Zöchbauer, Dec 05 '13 at 06:24

Don't forget to specify the headers as Content-type: application/json as without it the data is text/html. Silly mistake.

Updated POST here:

sendData = JSON.encode(data);

_httpRequest = new HttpRequest() ..open(method, url) ..setRequestHeader("Authorization", "Bearer " + tokenKey) ..setRequestHeader("Content-type", "application/json") ..onLoadEnd.listen((e) => _loadEnd(_httpRequest)) ..overrideMimeType("application/json") ..send(sendData);
