HttpURLConnection：獲取響應代碼400

Question

我正在使用HttpURLConnection從Java打服務器。

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

對於URL編碼，請使用URLEncoder.encode(url, "UTF-8");

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

當我嘗試在瀏覽器中打開上述URL時，響應代碼為OK(200) 。 服務器從Java返回response code 400 。

代碼段：

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();

還嘗試了URLEncoder.encode(url,"UTF-8")對URL進行編碼。

提前致謝。

為我工作：

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);

字符串輸出包含以下內容：

我從執行您的代碼中得到200的響應，也許您在代理或類似的支持下？
