无法从瓶

Question

得到JSON网络令牌我有app.py下面的代码：

from flask import Flask 
from flask_jwt import JWT, jwt_required, current_identity 
from werkzeug.security import safe_str_cmp 

class User(object): 
    def __init__(self, id, username, password): 
     self.id = id 
     self.username = username 
     self.password = password 

    def __str__(self): 
     return "User(id='%s')" % self.id 

users = [ 
    User(1, 'user1', 'abcxyz'), 
    User(2, 'user2', 'abcxyz'), 
] 

username_table = {u.username: u for u in users} 
userid_table = {u.id: u for u in users} 

def authenticate(username, password): 
    user = username_table.get(username, None) 
    if user and safe_str_cmp(user.password.encode('utf-8'), password.encode('utf-8')): 
     return user 

def identity(payload): 
    user_id = payload['identity'] 
    return userid_table.get(user_id, None) 

app = Flask(__name__) 
app.debug = True 
app.config['SECRET_KEY'] = 'super-secret' 

jwt = JWT(app, authenticate, identity) 

@app.route('/protected') 
@jwt_required() 
def protected(): 
    return '%s' % current_identity 

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

当我尝试做一个POST请求，以获得从邮差的身份验证令牌： http://127.0.0.1:5000/auth

{ “用户名”：“乔”， “密码”：“通” }

我得到一个特殊的错误，我不能够解决：

我完全不知道发生了什么问题。有人可以帮助我吗？

Answer 1

查看https://github.com/vimalloc/flask-jwt-extended或https://github.com/vimalloc/flask-jwt-simple作为Flask-JWT的替代品。他们设计得更好，最新，并且仍然保持着（我是作者，所以我当然有偏见）。

Answer 2

确保选中已设置正确的头

内容类型：应用程序/ JSON

尝试卷曲的交叉检查

$ curl -H "Content-Type: application/json" -X POST -d '{ "username": "joe", "password": "pass" }' http://localhost:5000/auth
