通过Flask测试客户端请求传递Cookie标头 [英] Pass cookie header with Flask test client request

问题描述

我无法让Flask测试客户端通过Cookie.这段代码曾经可以正常工作，并且我认为环境中的某些内容已更改，这打破了这一点.我最近创建了一个新的Python 3.7 virtualenv并安装了Flask 1.0.2.

 从flask导入Flask，jsonify，请求app = Flask(__ name__)@ app.route('/cookie_echo')def cookie_echo():返回jsonify(request.cookies)使用app.test_client()作为客户端:响应= client.get("/cookie_echo"，标头= {"Cookie":"abc = 123; def = 456"})打印(response.get_data(as_text = True)) 

运行示例将打印 {} ，但是我希望它可以打印 {"abc":"123"，"def":"456"} .

如果我通过 flask run 运行我的应用程序，则发送带有curl的标头:

 <代码> $ curl -H"Cookie:abc = 123; def = 456" http://localhost:5000/cookie_echo{"abc":"123"，"def":"456"} 

解决方案

Client 管理cookie，您不应在 headers = {} 中手动传递它们.由于Werkzeug 0.15中的更改，因此不希望手动传递 Cookie 标头，该标头不再起作用.使用 client.set_cookie 设置cookie，或在响应中设置cookie，它将与下一个请求一起发送.

  c = app.test_client()c.set_cookie('localhost'，'abc'，'123')c.set_cookie('localhost'，'def'，'456')c.get('/cookie_echo') 

I am having trouble getting the Flask test client to pass cookies. This code used to work and I presume something in my environment changed, which breaks this. I recently created a new Python 3.7 virtualenv and installed Flask 1.0.2.

from flask import Flask, jsonify, request

app = Flask(__name__)


@app.route('/cookie_echo')
def cookie_echo():
    return jsonify(request.cookies)


with app.test_client() as client:
    response = client.get("/cookie_echo", headers={"Cookie": "abc=123; def=456"})
    print(response.get_data(as_text=True))

Running the example prints {}, but I expect it to print {"abc":"123","def":"456"}.

If I run my app via flask run, sending headers with curl works:

$ curl -H "Cookie: abc=123; def=456" http://localhost:5000/cookie_echo
{"abc":"123","def":"456"}

解决方案

The Client manages cookies, you should not pass them manually in headers={}. Due to changes in Werkzeug 0.15, passing a Cookie header manually, which was not intended, no longer works. Use client.set_cookie to set a cookie, or set the cookie in a response and it will be sent with the next request.

c = app.test_client()
c.set_cookie('localhost', 'abc', '123')
c.set_cookie('localhost', 'def', '456')
c.get('/cookie_echo')
