android 应用中 PUT 请求的错误响应

Question

我正在开发一个 Android 应用程序，它应该向本地服务器发送 PUT 请求，当我使用 curl 尝试相同的请求时，我得到了成功响应，但是从 Android 应用程序我收到 PUT 请求的错误，这是来自移动应用程序和 curl 的请求，我使用 netcat[= 在我的 PC 上收听了这两个请求14=]

user@Laptop:~$ nc -l 192.168.1.104 55555
PUT /api/relay/0 HTTP/1.1
Host: 192.168.1.104:55555
User-Agent: curl/7.58.0
Accept: application/json
Content-Length: 31
Content-Type: application/x-www-form-urlencoded

这是我的androidjava请求

public void jsonRequestVolley(int method, String url, String requestBody) {         
        RequestQueue queue = Volley.newRequestQueue(context); 

        JsonObjectRequest jsonRequest = new JsonObjectRequest(   
                method,                           
                url,                                            
                requestBody,
                successResponse(),  
                errorResponse()   
        )  
        {

            /**
             * Passing some request headers
             * */
            @Override
            public Map<String, String> getHeaders() {
                HashMap<String, String> headers = new HashMap<String, String>();
                headers.put("Accept", "application/json");
                return headers;
            }

        };

        queue.add(jsonRequest);
    }

有效的 curl 命令是

curl -X PUT -H "Accept: application/json" http://192.168.1.105:55555/api/relay/0 --data "apikey=2E5DE48567FB10F2&value=1"```

由于本地服务器要求，我修复了 header，现在可以正常工作了，看起来像

PUT /api/relay/0 HTTP/1.1
Accept: application/json
Content-Type: application/x-www-form-urlencoded
User-Agent: Dalvik/2.1.0 (Linux; U; Android 9; HRY-LX1MEB Build/HONORHRY-LX1MEB)
Host: 192.168.1.104:55555
Connection: Keep-Alive
Accept-Encoding: gzip
Content-Length: 31

我在 Android 代码中添加了以下内容

@Override
            public Map<String, String> getHeaders() {
                HashMap<String, String> headers = new HashMap<String, String>();

                headers.put("Accept", "application/json");
                return headers;
            }

@Override
            public String getBodyContentType() {
                return "application/x-www-form-urlencoded";
            }

全部在请求代码中。
