java - 如何在java中使用以下curl post命令？

Question

我已经研究了堆栈溢出的不同线程并做了一些研究，在建立 http 连接后我无法在 java 中运行此代码。相同的命令在命令行中运行得很好

curl -X POST --header "Content-Type: application/json" --header "Accept: */*" -d "data" "http://a url"

我需要上面的curl命令的java代码，我还无法想出任何有值(value)的东西

对于仍在寻找的人

{String urly = "your url";
URL obj = new URL(urly);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();

con.setRequestMethod("POST");
con.setRequestProperty("Content-Type","application/json");


con.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(con.getOutputStream());
wr.writeBytes(the data string);
wr.flush();
wr.close();

int responseCode = con.getResponseCode();
System.out.println("Response Code : " + responseCode);

BufferedReader iny = new BufferedReader(
new InputStreamReader(con.getInputStream()));
  String output;
  StringBuffer response = new StringBuffer();

  while ((output = iny.readLine()) != null) {
   response.append(output);
  }
  iny.close();

  //printing result from response
  System.out.println(response.toString());
 }
