Question

我使用HttpURLConnection从Java命中服务器。

URL: http://clicks.pureleads.com/c/E1oTzCqNzcgtN8YfNs5wg25lxQ7X8*PEqjqks**E|l9gsgSg6ZyKU7FdR0WkUDvIZ2jgG9hhb1qfSlUJpaojsCMystWBEfw6EacQ4K)zd6CtREq0PA68Uj4rPqLEsBgQdK6pgV88epNw3LF7S3X4erNQmaF26N)47Eb8H9O58bmMrEwGTBJ*avyzVCGxuyuaAoqBkOBafBru3i44S*oP74Wu4toNaTW3onZrpV9qsIqsMb3kC9J2s4RDStFqTAzH0VPlO)ZI0SWtJAchAt76suO2vTJdu6WVynplETGZD4I6DvNiQ1CSnQtSE0G2ing((

对于对网址进行编码，请使用URLEncoder.encode(url, "UTF-8");

Encoded URL:
http://clicks.pureleads.com/c/E1oTzCqNzcgtN8YfNs5wg25lxQ7X8*PEqjqks**E%7Cl9gsgSg6ZyKU7FdR0WkUDvIZ2jgG9hhb1qfSlUJpaojsCMystWBEfw6EacQ4K)zd6CtREq0PA68Uj4rPqLEsBgQdK6pgV88epNw3LF7S3X4erNQmaF26N)47Eb8H9O58bmMrEwGTBJ*avyzVCGxuyuaAoqBkOBafBru3i44S*oP74Wu4toNaTW3onZrpV9qsIqsMb3kC9J2s4RDStFqTAzH0VPlO)ZI0SWtJAchAt76suO2vTJdu6WVynplETGZD4I6DvNiQ1CSnQtSE0G2ing((

当我尝试在浏览器中打开上述网址时，响应代码为OK(200)。从Java，服务器返回response code 400。

代码段：

URI uri = new URI("http", "clicks.pureleads.com","/c/E1oTzCqNzcgtN8YfNs5wg25lxQ7X8*PEqjqks**E|l9gsgSg6ZyKU7FdR0WkUDvIZ2jgG9hhb1qfSlUJpaojsCMystWBEfw6EacQ4K)zd6CtREq0PA68Uj4rPqLEsBgQdK6pgV88epNw3LF7S3X4erNQmaF26N)47Eb8H9O58bmMrEwGTBJ*avyzVCGxuyuaAoqBkOBafBru3i44S*oP74Wu4toNaTW3onZrpV9qsIqsMb3kC9J2s4RDStFqTAzH0VPlO)ZI0SWtJAchAt76suO2vTJdu6WVynplETGZD4I6DvNiQ1CSnQtSE0G2ing((",null);
String url = uri.toString();
serverAddress = new URL(url);
connection = (HttpURLConnection) serverAddress.openConnection();
connection.setConnectTimeout(2000);
connection.setReadTimeout(2000);
connection.connect();

还尝试使用URLEncoder.encode(url,"UTF-8")对网址进行编码。

先谢谢。

适合我：

URI uri = new URI("http", "clicks.pureleads.com","/c/E1oTzCqNzcgtN8YfNs5wg25lxQ7X8*PEqjqks**E|l9gsgSg6ZyKU7FdR0WkUDvIZ2jgG9hhb1qfSlUJpaojsCMystWBEfw6EacQ4K)zd6CtREq0PA68Uj4rPqLEsBgQdK6pgV88epNw3LF7S3X4erNQmaF26N)47Eb8H9O58bmMrEwGTBJ*avyzVCGxuyuaAoqBkOBafBru3i44S*oP74Wu4toNaTW3onZrpV9qsIqsMb3kC9J2s4RDStFqTAzH0VPlO)ZI0SWtJAchAt76suO2vTJdu6WVynplETGZD4I6DvNiQ1CSnQtSE0G2ing((",null);
    String url = uri.toString();
    URL serverAddress = new URL(url);
    HttpURLConnection connection = (HttpURLConnection) serverAddress.openConnection();
    connection.setConnectTimeout(2000);
    connection.setReadTimeout(2000);
    connection.connect();

    InputStream inputStream = connection.getInputStream();

    String output = IOUtils.toString(inputStream);

字符串输出包含以下内容：

           //The user has hit back button
           if (document.getElementById('final').value == 1) {
              document.getElementById('final').value = 0;
              //The ad opened in new window
              if (document.getElementById('hist').value == 0) {
                 self.location.replace(back_url);
              }

           }
           else {
              //IE doesn't send referrer when used with replace
              var created_link = document.createElement("a");
              created_link.href = dest_url;
              document.body.appendChild(created_link);
              //set the back button variable and new window variable
              created_link.click(document.getElementById('final').value = 1,     document.getElementById('hist').value = history.length);
           }
        }
        else {
            if (document.images) {
                self.location.replace(dest_url);
            }

我从执行代码得到200响应，也许你是代理或类似的？

HttpURLConnection：获取响应代码400
