python - 获取 Python Django 'SERVER_PROTOCOL' TypeError:'NoneType' 对象不可下标
问题描述
我编写了 PUT 请求 API 来设置用户密码。我写了这么多视图,但我没有遇到像下面的视图功能这样的问题。
视图.py
@api_view(['PUT'])
@permission_classes([])
def setForgotPasswordWithNewPassword(request):
data = request.data
print(data)
user = User.objects.get(username=data['username'])
secret_key = request.data['secretkey']
backend_secretkey = cache.get('reset_pwd_%s' % (data['username']))
if backend_secretkey:
if backend_secretkey == secret_key:
if user:
user.set_password(data['password'])
# print(user.password)
user.save()
return Response({"msg":"Your password has been successfully changed"},status=200)
else:
return Response({"error":"Username does not exist on our system"},status=403)
else:
return Response({"error": "Your not authorized to use this link"}, status=403)
else:
return Response({"error": "Your password link has been expired, please try again"}, status=403)
使用 Postman,我在命令行上没有收到任何异常。但是当我使用我的 Angular 项目访问这个 API 时,得到了以下异常,并且由于再次加载了这个异常 wsgi 服务器,所以再次加载到首页。但更改密码有效。所以我很想知道我遇到的这个错误。

使用邮递员工具调用没有像上面那样出现任何异常
我的 Angular 调用:
setForgotPassword(data):Observable<any>{
return this.http.put<any>(this._base_url+this._setForgotPassword_url,data)
}
打字稿:
setPassword(secretkey){
this.data.secretkey = secretkey
console.log(this.data)
this.usr_srv.setForgotPassword(this.data).subscribe(
res => {
console.log(res)
// let dialogRef = this.dialog.open(DialogDataExampleDialog,{
// data: {msg: 'Your password has been successfully set',color:"green"}
// });
// dialogRef.afterClosed().subscribe(result => {
// this._router.navigate(['/login'])
// });
},
err =>{
console.log(err)
// let dialogRef = this.dialog.open(DialogDataExampleDialog,{
// data: {msg: err.error.error,color:"red"}
// });
// dialogRef.afterClosed().subscribe(result => {
// this._router.navigate(['/login'])
// });
}
)
}
