connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");

Integer.toString(urlParameters.getBytes().length));
connection.setRequestProperty("Content-Language", "en-US");
connection.setUseCaches (false);
connection.setDoInput(true);

//Send request
DataOutputStream wr = new DataOutputStream (

wr.writeBytes (urlParameters);

wr.close ();
//Get Response
InputStream is = connection.getInputStream();
BufferedReader rd = new BufferedReader(new InputStreamReader(is));
String line;
StringBuffer response = new StringBuffer();
while((line = rd.readLine()) != null) {
response.append(line);
response.append('\r');
}
rd.close();
System.out.println("message="+response.toString());

我正在尝试使用HTTP POST方法发送JSON对象.上面是代码,但是我得到了
I am trying to send a JSON Object using the HTTP POST method. Above is the code but I am getting
java.io.IOException: Server returned HTTP response code: 415 for URL: ....
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)
at TestingPost.main(TestingPost.java:38)"
我的代码有什么问题?
推荐答案
您获得的HTTP响应代码为
The HTTP response code you get is
415 Unsupported Media Type
这意味着服务器无法处理您发送给它的格式.您的HTTP请求设置了此标头:
This means that the server can not handle the format you sent to it. Your HTTP request sets this header:
Content-Type: application/x-www-form-urlencoded
这是提交表单时浏览器发送的内容类型.如果要发送JSON,请使用以下标头:
This is the content type sent by a browser if a form is submitted. If you want to send JSON, use this header:
Content-Type: application/json
