带有 JSON 的 Http 415 不支持的媒体类型错误

all

我正在使用 JSON 请求调用 REST 服务,它以HTTP 415 "Unsupported Media Type"错误响应。

请求内容类型设置为("Content-Type", "application/json; charset=utf8")

如果我不在请求中包含 JSON 对象,它工作正常。我正在使用google-gson-2.2.4JSON 库。

我尝试使用几个不同的库,但没有任何区别。

有人可以帮我解决这个问题吗?

这是我的代码:

public static void main(String[] args) throws Exception
{

    JsonObject requestJson = new JsonObject();
    String url = "xxx";

    //method call for generating json

    requestJson = generateJSON();
    URL myurl = new URL(url);
    HttpURLConnection con = (HttpURLConnection)myurl.openConnection();
    con.setDoOutput(true);
    con.setDoInput(true);

    con.setRequestProperty("Content-Type", "application/json; charset=utf8");
    con.setRequestProperty("Accept", "application/json");
    con.setRequestProperty("Method", "POST");
    OutputStream os = con.getOutputStream();
    os.write(requestJson.toString().getBytes("UTF-8"));
    os.close();


    StringBuilder sb = new StringBuilder();  
    int HttpResult =con.getResponseCode();
    if(HttpResult ==HttpURLConnection.HTTP_OK){
    BufferedReader br = new BufferedReader(new   InputStreamReader(con.getInputStream(),"utf-8"));

        String line = null;
        while ((line = br.readLine()) != null) {  
        sb.append(line + "\n");  
        }
         br.close(); 
         System.out.println(""+sb.toString());

    }else{
        System.out.println(con.getResponseCode());
        System.out.println(con.getResponseMessage());  
    }

}
public static JsonObject generateJSON () throws MalformedURLException

{
   String s = "http://www.example.com";
        s.replaceAll("/", "\\/");
    JsonObject reqparam=new JsonObject();
    reqparam.addProperty("type", "arl");
    reqparam.addProperty("action", "remove");
    reqparam.addProperty("domain", "staging");
    reqparam.addProperty("objects", s);
    return reqparam;

}
}

的值为requestJson.toString()

{"type":"arl","action":"remove","domain":"staging","objects":"http://www.example.com"}

不确定原因,但删除行charset=utf8解决 con.setRequestProperty("Content-Type", "application/json; charset=utf8")了问题。
