我试图在java中编写以下php代码部分。我将提供php代码和java代码。我想要帮助的是a）我是否在正确的轨道上和b）与＆＃34的关系;请在这里帮助＆＃34;评论，我不确定如何在java中这样做。这一行是header("Location: ".$strCitiRedirectURL.$content."");
提前谢谢。
php代码：
$req =& new HTTP_Request($strCitiLoginURL);
$req->setMethod(HTTP_REQUEST_METHOD_POST);
$req->addPostData("instusername", $strInstUsername);
$req->addPostData("institution", $strInstitution);
$req->addPostData("key", $strInstitutionKey);
$req->addPostData("type", "returning");
$response = $req->sendRequest();
if(isset($_GET['showDebug'])){
print $req->_buildRequest();
}
if (PEAR::isError($response)) {
$content = $response->getMessage();
} else {
$content = $req->getResponseBody();
}
/* Check for 44 Character UUID */
if (preg_match($pattern,$content)){
print 'Success';
ob_start();
header("Location: ".$strCitiRedirectURL.$content."");
ob_flush();
/* No UUID. Login to CITI failed. We may need a new user */
}elseif ($content == "- error: learner not affiliated with institution, add learner or provide username and password"){
// Resubmit as a new user
/* Package data up to post to CITI */
$req =& new HTTP_Request($strCitiLoginURL);
$req->setMethod(HTTP_REQUEST_METHOD_POST);
$req->addPostData("instusername", $strInstUsername);
$req->addPostData("institution", $strInstitution);
$req->addPostData("key", $strInstitutionKey);
$req->addPostData("type", "new");
$req->addPostData("first", $strFirst);
$req->addPostData("last", $strLast);
$req->addPostData("email", $strEmail);
$response = $req->sendRequest();
if(isset($_GET['showDebug'])){
print $req->_buildRequest();

答案 0 :(得分：1)
我相信
header("Location: ".$strCitiRedirectURL.$content."");
与Java中的以下相同（使用你的wr对象）：
wr.sendRedirect("http://path.to.redirect/");
你也可以转发请求，但我觉得你只是希望客户端重定向到citirewards或者其他什么，在这种情况下sendRedirect就是解决方案。
