Question

实际上，当我将json导入POSTMAN应用程序并发送请求时，一切运行正常。但是，当我尝试使用ajax调用或直接点击api进行POST时，就会出现问题

我曾尝试删除api密钥，但未做出任何授权

这是我的API-https://ym4j4pt5mf.execute-api.us-east-1.amazonaws.com/Beta 我正在尝试将其发布为原始正文：-

{
  "DestinationBot": "iSearchBot",
  "SenderID": "12345",
  "botAlias": "iSearchBotBeta",
  "message": {
    "text": "hi"
  }
}

这是我通过POSTMAN从api网关导入api时收到的响应

                    },
                    {
                        "text": "No",
                        "value": "No"
                    }
                ]
            }
        ]
    }
}

在此先感谢您的帮助

好的，我不确定您的设置，但我会为您指明方向。问题是请求需要以其原始主体完成，并键入application / json。此处的关键是“ Content-Type”和有效负载JSON。如果您没有完全使用此lib，那么我敢肯定其他人也会有类似的选择。

import http.client

conn = http.client.HTTPConnection("ym4j4pt5mf,execute-api,us-east-1,amazonaws,com")

payload = "{\n  \"DestinationBot\": \"iSearchBot\",\n  \"SenderID\": \"12345\",\n  \"botAlias\": \"iSearchBotBeta\",\n  \"message\": {\n    \"text\": \"hi\"\n  }\n}"

headers = {
  'Content-Type': "application/json",
  'cache-control': "no-cache",
  'Postman-Token': "0de52364-daf7-4977-8b82-55d5258a4046"
  }

conn.request("POST", "Beta", payload, headers)

res = conn.getresponse()
data = res.read()

print(data.decode("utf-8"))

或者，如果您使用请求：

import requests

url = "https://ym4j4pt5mf.execute-api.us-east-1.amazonaws.com/Beta"

payload = "{\n  \"DestinationBot\": \"iSearchBot\",\n  \"SenderID\": \"12345\",\n  \"botAlias\": \"iSearchBotBeta\",\n  \"message\": {\n    \"text\": \"hi\"\n  }\n}"
headers = {
    'Content-Type': "application/json",
    'cache-control': "no-cache",
    'Postman-Token': "245fea6e-5604-47dd-96ec-745ae2b6cde0"
    }

response = requests.request("POST", url, data=payload, headers=headers)

print(response.text)

好了，这可以解决您的问题，我想问题出在json字符串化上，它很容易工作

<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function(){

var value={ 
  'DestinationBot': "iSearchBot",
  'SenderID': "12345",
  'botAlias': "iSearchBotBeta",
  'message': {
    'text': "hi"
  }
};
value = JSON.stringify(value);
$.ajax({
  url:'https://ym4j4pt5mf.execute-api.us-east-1.amazonaws.com/Beta/',
  headers:{  
    'Content-Type': "application/json",   
  },
  crossDomain: true,
  method:'POST',
  dataType:'json',
  data:value,
  success:function(msg){
    console.log(msg)
  }
});
});

</script>
</head>
<body>

<input type="text"></input>

</body>
</html>

我无法将json发布到我的api lambda函数。我收到{“ message”：“ Missing Authentication Token”}
