How to send requests with JSONs in unit tests
提问by Sepehr Nazari
I have code within a Flask application that uses JSONs in the request, and I can get the JSON object like so:
我在 Flask 应用程序中有代码，它在请求中使用 JSON，我可以像这样获取 JSON 对象：
Request = request.get_json()
This has been working fine, however I am trying to create unit tests using Python's unittest module and I'm having difficulty finding a way to send a JSON with the request.
这一直工作正常，但是我正在尝试使用 Python 的 unittest 模块创建单元测试，但我很难找到一种方法来发送带有请求的 JSON。
response=self.app.post('/test_function',
data=json.dumps(dict(foo = 'bar')))
This gives me:
这给了我：
>>> request.get_data()
'{"foo": "bar"}'
>>> request.get_json()
None
Flask seems to have a JSON argument where you can set json=dict(foo='bar') within the post request, but I don't know how to do that with the unittest module.
Flask 似乎有一个 JSON 参数，你可以在 post 请求中设置 json=dict(foo='bar') ，但我不知道如何使用 unittest 模块来做到这一点。

Changing the post to
将帖子更改为
response=self.app.post('/test_function',
data=json.dumps(dict(foo='bar')),
content_type='application/json')
fixed it.
修复。

UPDATE:Since Flask 1.0 released flask.testing.FlaskClientmethods accepts jsonargument and Response.get_jsonmethod added, see example.
更新：由于 Flask 1.0 发布的flask.testing.FlaskClient方法接受添加的json参数和Response.get_json方法，请参见示例。
for Flask 0.x you may use receipt below:
对于 Flask 0.x，您可以使用以下收据：
from flask import Flask, Response as BaseResponse, json
from flask.testing import FlaskClient
from werkzeug.utils import cached_property
class Response(BaseResponse):
@cached_property
def json(self):
return json.loads(self.data)
class TestClient(FlaskClient):
def open(self, *args, **kwargs):
if 'json' in kwargs:
kwargs['data'] = json.dumps(kwargs.pop('json'))
kwargs['content_type'] = 'application/json'
return super(TestClient, self).open(*args, **kwargs)
app = Flask(__name__)
app.response_class = Response
app.test_client_class = TestClient
app.testing = True
