邮递员响应：找到与请求匹配的多个操作

Question

我有两个同名但参数不同的方法，应该return一个HttpResponseMessage

public HttpResponseMessage ReceivedData(JObject jsonData)

和

public HttpResponseMessage ReceivedData(double longitude, double latitude)

如果我从 Postman 发出 POST 请求，第二个请求使用

http://localhost:6296/api/MyController/ReceivedData?longitude=0&latitude=0

一切正常，但第一个

http://localhost:6296/api/MyController/ReceivedData

和JSONBody{"longitude":0, "latitude":0, "otherData":"test"} 我得到

"ExceptionMessage": "Multiple actions were found that match the request

我不明白我做错了什么。

Answer 1

试试这个

[HttpPost]
public HttpResponseMessage ReceivedData(JObject jsonData)

[HttpGet]
public HttpResponseMessage ReceivedData(double longitude, double latitude)

或者如果您仍然希望两者都 post，请将第一个的操作更改为 ReceivedJsonData

[HttpPost("~/api/My/ReceivedJsonData")]
public HttpResponseMessage ReceivedData(JObject jsonData)

邮递员响应：找到与请求匹配的多个操作

Postman response: Multiple actions were found that match the request
