How to post data structure like json to flask?

Question

I have a data structure like this:

I\'m try to send it to server by $.ajax

You are sending your data encoded as query string instead of JSON. Flask is capable of processing JSON encoded data, so it makes more sense to send it like that. Here's what you need to do on the client side:

$.ajax({
    type: 'POST',
    // Provide correct Content-Type, so that Flask will know how to process it.
    contentType: 'application/json',
    // Encode your data as JSON.
    data: JSON.stringify(post_obj),
    // This is the type of data you're expecting back from the server.
    dataType: 'json',
    url: '/some/url',
    success: function (e) {
        console.log(e);
    }
});

On the server side data is accessed via request.json (already decoded):

content = request.json['content']
