我正试着做一个手动请求与邮递员注册。 有一个带有标题的POST请求:

Content-Type:application/x-amz-json-1.1
X-Amz-Target:AWSCognitoIdentityProviderService.SignUp
未经加工的身体看起来是这样的:

{
    "ClientId": "xxxxxxxxx",
    "Password": "xxxxxxxx",
    "UserAttributes": [ 
                        {
                            "Name": "Name",
                            "Value": "xxxxxx@dd.com"
                        }
                    ],
    "Username": "xxxxxxx"
} 
我在回答这个错误时得到:

{"__type":"UnknownOperationException"}
有什么线索可以告诉我为什么会出现这个错误吗?

请参考

因此,json数据应该是:

{
   "DesiredDeliveryMediums": [ "string" ],
   "ForceAliasCreation": boolean,
   "MessageAction": "string",
   "TemporaryPassword": "string",
   "UserAttributes": [ 
      { 
         "Name": "string",
         "Value": "string"
      }
   ],
   "Username": "string",
   "UserPoolId": "string",
   "ValidationData": [ 
      { 
         "Name": "string",
         "Value": "string"
      }
   ]
}

没有
