2、客户端例子：

2. /**
3. * 客户端调用API
4. * site http://bbs.it-home.org
5. */
6. header('Content-Type:text/html;charset=utf-8'); //避免输出乱码
8. function httpPost($url, $parms) {
9. $url = $url . $parms;
10. if (($ch = curl_init($url)) == false) {
11. throw new Exception(sprintf("curl_init error for url %s.", $url));
12. }
13. curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
14. curl_setopt($ch, CURLOPT_HEADER, 0);
15. curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 600);
16. curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
17. if (is_array($parms)) {
18. curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data;'));
19. }
20. $postResult = @curl_exec($ch);
21. $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
22. if ($postResult === false || $http_code != 200 || curl_errno($ch)) {
23. $error = curl_error($ch);
24. curl_close($ch);
25. throw new Exception("HTTP POST FAILED:$error");
26. } else {
27. // $postResult=str_replace("\xEF\xBB\xBF", '', $postResult);
28. switch (curl_getinfo($ch, CURLINFO_CONTENT_TYPE)) {
29. case 'application/json':
30. $postResult = json_decode($postResult);
31. break;
32. }
33. curl_close($ch);
34. return $postResult;
35. }
36. }
38. $postUrl = "http://pujia.test.com/api/server.php";
40. $p=$_GET['p'];
41. if ($p =="selectuserinfo") {
43. $username = $_GET['username'];
44. $parms = "?action=selectuserinfo&username=" . $username . "";
46. } elseif ($p =="adduserinfo") {
48. $username = $_GET['username'];
49. $userpassword = $_GET['userpassword'];
