jquery - Accessing request.json in Flask results in an exception -


i'm using flask 0.10.1, , have flask function starts this:

@app.route('/logs', methods=['post']) def add_log():     db = get_db()      print("\ninside /logs post\n===================")     print(request.headers)      print('--------------')     print(request.form)      print('--------------')     try:         print(request.json)     except exception e:         print('something real bad happened')         print(e)      if not request.json:         print("abandon ship!")         abort(400)

i'm making ajax request location via jquery:

    $.ajax({       url: '/logs',       contenttype: 'application/json',       type: 'post',       data: {'body': 'you know use body', 'tags': 'tagggssss'},       success: function(data) {         console.log(data);       }.bind(this),       error: function(xhr, status, err) {         console.error(this.props.url, status, err.tostring());       }.bind(this)     });

it appears upon trying access request.json, flask functoin fails. here's flask server output:

inside /logs post =================== x-requested-with: xmlhttprequest accept-language: en-us,en;q=0.5 host: 127.0.0.1:5000 referer: http://127.0.0.1:5000/ connection: keep-alive content-type: application/json; charset=utf-8 pragma: no-cache content-length: 55 accept-encoding: gzip, deflate accept: */* user-agent: mozilla/5.0 (x11; linux x86_64; rv:28.0) gecko/20100101 firefox/28.0 cache-control: no-cache   -------------- immutablemultidict([]) -------------- real bad happened 400: bad request 127.0.0.1 - - [11/apr/2014 13:16:30] "post /logs http/1.1" 400 -

the flask docs state:

if mimetype application/json [request.json, if understand correctly] contain parsed json data. otherwise none.

this leads me believe parsing json somehow failing, though i'm not sure how be. how can see problem is?

you not posting json; mimetype claims are. use json.stringify():

  data: json.stringify({'body': 'you know use body', 'tags': 'tagggssss'}),
