java - 使用 JAVA 从 url 下载二进制文件给出 403 错误但 PHP 工作正常

Question

我写了一些 java 代码用于从一个网站下载 mp3。它给出了 403 状态码。我在谷歌上搜索了一下，发现我需要设置 User-Agent 和 Referrer(因为他们需要) .我设置了这两个仍然没有用。所以我捕获了我发送到我得到的网站的请求，我需要发送的内容和所有内容。我设置了所有必需的 header ，但我得到了相同的 403。我对此做了一些小研究，我使用了 php 和 windows curl (来自 curl.haxx.se 的 curl.exe)并且工作正常。

这是我写的代码

Java 使用 Apache HttpClient(给出 403)

HttpClient httpClient = new HttpClient();       
GetMethod get = new GetMethod("http://redu.su/download_file.php?id=7745333&filename=k-j-yesudas-mavapanisa-silpa.mp3&ts=130944042611814004&hash=b825427b3a63b28c8a4ba3b2a34294fb");
get.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
get.setRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.80 Safari/537.36");
get.setRequestHeader("Referrer", "http://redmp3.cc/7745324/k-j-yesudas-sreeragamo.html");
httpClient.executeMethod(get); 
System.out.println(get.getStatusCode());

Java 使用 URL 和 URLConnection(给出 403)

URL u = new URL("http://redu.su/download_file.php?id=7745333&filename=k-j-yesudas-mavapanisa-silpa.mp3&ts=130944042611814004&hash=b825427b3a63b28c8a4ba3b2a34294fb");
HttpURLConnection  uc = (HttpURLConnection) u.openConnection(); // Without type cast to HttpURLConnection , URLConnection also not working
uc.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.80 Safari/537.36");
uc.addRequestProperty("Referrer", "http://redmp3.cc/7745324/k-j-yesudas-sreeragamo.html");
uc.connect();
System.out.println(uc.getResponseMessage());// Forbidden output

PHP 使用 curl(获取输出)

<?php
  $curl = curl_init();
  curl_setopt ($curl, CURLOPT_URL, "http://redu.su/download_file.php?id=7745333&filename=k-j-yesudas-mavapanisa-silpa.mp3&ts=130944042611814004&hash=b825427b3a63b28c8a4ba3b2a34294fb");
  curl_setopt ($curl, CURLOPT_REFERER, "http://redmp3.cc/7745324/k-j-yesudas-sreeragamo.html");
  curl_setopt ($curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.80 Safari/537.36");
  $contents = curl_exec($curl);
  echo $contents;
  exit;
?>

Windows curl(获取输出)

curl "http://redu.su/download_file.php?id=7745333&filename=k-j-yesudas-mavapanisa-silpa.mp3&ts=130944042611814004&hash=b825427b3a63b28c8a4ba3b2a34294fb" -H "User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.80 Safari/537.36" -H "Referer: http://redmp3.cc/7745324/k-j-yesudas-sreeragamo.html" --compressed

我在这里犯了什么错误？为什么我在使用 Java 时无法获得 200 响应？

提前致谢。

Answer 1

虽然我自己现在遇到 404 错误，但我非常有信心您有一个多余的 R。

是Referer 不是Referrer

我的代码，基于 HttpClient 4.5:

        HttpClient httpClient = HttpClients.createDefault();    

        HttpGet get = new HttpGet("http://redu.su/download_file.php?id=7745333&filename=k-j-yesudas-mavapanisa-silpa.mp3&ts=130944042611814004&hash=b825427b3a63b28c8a4ba3b2a34294fb");
        get.setHeader(HttpHeaders.USER_AGENT, "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.80 Safari/537.36");
        get.setHeader(HttpHeaders.REFERER, "http://redmp3.cc/7745324/k-j-yesudas-sreeragamo.html");

        HttpResponse res = httpClient.execute(get); 
        System.out.println(res.getStatusLine());
