2、客户端例子：

/**
* 客户端调用API
* site http://bbs.it-home.org
*/
header('Content-Type:text/html;charset=utf-8'); //避免输出乱码
function httpPost($url, $parms) {
$url = $url . $parms;
if (($ch = curl_init($url)) == false) {
throw new Exception(sprintf("curl_init error for url %s.", $url));
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 600);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
if (is_array($parms)) {
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data;'));
}
$postResult = @curl_exec($ch);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($postResult === false || $http_code != 200 || curl_errno($ch)) {
$error = curl_error($ch);
curl_close($ch);
throw new Exception("HTTP POST FAILED:$error");
} else {
// $postResult=str_replace("\xEF\xBB\xBF", '', $postResult);
switch (curl_getinfo($ch, CURLINFO_CONTENT_TYPE)) {
case 'application/json':
$postResult = json_decode($postResult);
break;
}
curl_close($ch);
return $postResult;
}
}
$postUrl = "http://pujia.test.com/api/server.php";
$p=$_GET['p'];
if ($p =="selectuserinfo") {
$username = $_GET['username'];
$parms = "?action=selectuserinfo&username=" . $username . "";
} elseif ($p =="adduserinfo") {
$username = $_GET['username'];
$userpassword = $_GET['userpassword'];
$parms = "?action=adduserinfo&username=" . $username . "&userpassword=" . $userpassword . "";
} elseif ($p =="userlogin") {
$username = $_GET['username'];
$userpassword = $_GET['userpassword'];
$parms = "?action=userlogin&username=" . $username . "&userpassword=" . $userpassword . "";
}
$res = httpPost($postUrl, $parms); //$parms
$res = json_decode($res);
print_r(urldecode(json_encode($res)));
?>
