Flask RESTful POST JSON失败 [英] Flask RESTful POST JSON fails

问题描述

我有一个问题发布JSON通过curl从cmd（Windows7）到Flask RESTful。
这是我发布的：

I have a problem posting JSON via curl from cmd (Windows7) to Flask RESTful. This is what I post:

curl.exe -i -H "Content-Type: application/json" \
 -H "Accept: application/json" -X POST \
 -d '{"Hello":"Karl"}' http://example.net:5000/

这会导致一个错误的请求，我也不知道如何调试这个，通常我打印出信息到控制台，但这不工作。如何调试wsgi应用程序？看起来像一个绝望的任务...

It results in a bad request, also I don't know how to debug this, normally I would print out information to console, but this doesn't work. How do you debug wsgi apps? Seems like a hopeless task...

这是我在网上看到的简单的测试应用程序：

This is my simple test app as seen on the net:

from flask import Flask, request
from flask.ext.restful import Resource, Api

app = Flask(__name__)
api = Api(app)

class Test(Resource):
    def post(self):
        #printing request.data works
        json_data = request.get_json(force=True) # this issues Bad request
        # request.json also does not work
        return {}

api.add_resource(Test, '/')

if __name__ == '__main__':
    app.run(debug=True)

推荐答案

-d'{Hello：Karl}'

-d "{\"Hello\":\"Karl\"}"
