如何发送回令牌使用火力地堡验证

问题描述：

我正在开发Android应用程序，它使用火力地堡和我自己的服务器上运行的Django到Android。我打算做的是，我想首先使用android应用程序将用户身份验证到django服务器，该服务器随后生成Firebase文档中指定的自定义令牌。然后我想将生成的自定义令牌发回给android。如何发送回令牌使用火力地堡验证

我的问题是如何将自定义令牌发回给android？我试图发送为JSON对象。但它说JWT不是JSON可序列化的。

我从Android应用程序为JSON对象传递的用户名和密码，并用我的Django的服务器进行身份验证。

这里是我最小的Django代码：

import firebase_admin 
from firebase_admin import credentials 
from firebase_admin import auth 

cred = credentials.Certificate("firebase-admin.json") 
default_app = firebase_admin.initialize_app(cred) 

def validateuser(request): 
    json_data=json.loads(request.body.decode('utf-8')) 

    try: 
     // I verify the username and password and extract the uid 
     uid = 'some-uid' 
     custom_token = auth.create_custom_token(uid) 

     result={'TAG_SUCCESS': 1, 'CUSTOM_TOKEN': custom_token } 
    except: 
     result={'TAG_SUCCESS': 0, 'CUSTOM_TOKEN': '0'} 


    return HttpResponse(json.dumps(result), content_type='application/json')

但它说，自定义标记不是JSON序列化。这是不是这样做的方式？我如何将自定义令牌发送回android应用程序？

这是错误：

答

我想你使用python3版本。我发现问题是什么。

的auth.create_custom_token（UID）方法返回一个字节文字和字节字面不JSON序列化的。这就是你遇到错误的原因。您可以看到b'盈方的jwt令牌。

所以，你只是需要用下面的代码转换文本字符串的字节。

custom_token = (auth.create_custom_token(uid)).decode()
