問題描述

我有 curl 命令:

I have curl command:

curl -i -u guest:guest -H "content-type:application/json"
-XPUT  http://localhost:15672/api/traces/%2f/my-trace 
-d'{"format":"text","pattern":"#"}'

我想在 Java API 中創建 HTTP 請求，它會做同樣的事情.這個 curl 命令可以在這個 README 中找到.它用于在 RabbitMQ 上開始記錄日志.回應并不重要.

And I want to create HTTP Request in Java API which will do the same thing. This curl command can be found in this README. It is used to start recording log on RabbitMQ. Response is not important.

現在我創建了這樣的東西(我已經刪除了不太重要的行，即捕獲異常等)，但不幸的是它不起作用:

For now I created something like this (I've deleted less important lines i.e. with catching exception etc.), but unfortunately it doesn't work:

url = new URL("http://localhost:15672/api/traces/%2f/my-trace");
uc = url.openConnection();

uc.setRequestProperty("Content-Type", "application/json");
uc.setRequestProperty("format","json");
uc.setRequestProperty("pattern","#")
String userpass = "guest:guest";
String basicAuth = "Basic " + javax.xml.bind.DatatypeConverter.printBase64Binary(userpass.getBytes());
uc.setRequestProperty ("Authorization", basicAuth);

整個代碼

這是最終解決方案:

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.Proxy;
import java.net.InetSocketAddress;
import java.io.OutputStreamWriter;

public class Curl {

  public static void main(String[] args) {

    try {

    String url = "http://127.0.0.1:15672/api/traces/%2f/trololo";

    URL obj = new URL(url);
    HttpURLConnection conn = (HttpURLConnection) obj.openConnection();

    conn.setRequestProperty("Content-Type", "application/json");
    conn.setDoOutput(true);

    conn.setRequestMethod("PUT");

    String userpass = "user" + ":" + "pass";
    String basicAuth = "Basic " + javax.xml.bind.DatatypeConverter.printBase64Binary(userpass.getBytes("UTF-8"));
    conn.setRequestProperty ("Authorization", basicAuth);

    String data =  "{"format":"json","pattern":"#"}";
    OutputStreamWriter out = new OutputStreamWriter(conn.getOutputStream());
    out.write(data);
    out.close();

    new InputStreamReader(conn.getInputStream());   

    } catch (Exception e) {
    e.printStackTrace();
    }

  }

}
