微信公众平台消息接口(PHP)-官方的Demo有问题,下面个人进行了处理,事例代码也跑不通,我研究了一番,终于搞定.

首先:在你的服务器上上传好一个接口文件,如http://www.phpfensi.com/weixin.php 内容如下:

1. <?php
2. define("TOKEN", "weixin");
3. define("MESS","输入点啥吧");
4. $wechatObj = new wechatCallbackapiTest();
5. $wechatObj->valid();
6. //$wechatObj->responseMsg();
7. class wechatCallbackapiTest
8. {
9. public function valid()
10. {
11. $echoStr = $_GET["echostr"];
12. if($this->checkSignature()){
13. echo $echoStr;
14. exit;
15. }
16. }
17. public function responseMsg()
18. {
19. $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
20. if (!emptyempty($postStr)){
21. $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
22. $fromUsername = $postObj->FromUserName;
23. $toUsername = $postObj->ToUserName;
24. $keyword = trim($postObj->Content);
25. $time = time();
26. $textTpl = "<xml>
27. <ToUserName><![CDATA[%s]]></ToUserName>
28. <FromUserName><![CDATA[%s]]></FromUserName>
29. <CreateTime>%s</CreateTime>
30. <MsgType><![CDATA[%s]]></MsgType>
31. <Content><![CDATA[%s]]></Content>
32. <FuncFlag>0<FuncFlag>
33. </xml>";
34. if(!emptyempty( $keyword ))
35. {
36. $msgType = "text";
37. $contentStr = MESS;
38. $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
39. echo $resultStr;
40. }else{
41. echo MESS;
42. }
43. }else {
44. echo MESS;
45. exit;
46. }
47. }
48. private function checkSignature()
49. {
50. $signature = $_GET["signature"];
51. $timestamp = $_GET["timestamp"];
52. $nonce = $_GET["nonce"];
53. $token =TOKEN;
54. $tmpArr = array($token, $timestamp, $nonce);
55. sort($tmpArr);
56. $tmpStr = implode( $tmpArr );
57. $tmpStr = sha1( $tmpStr );
58. if( $tmpStr == $signature ){
59. return true;
60. }else{
61. return false;
62. }
63. }
64. }
65. ?>

然后:设置回复接口,填好URL和Token(必须跟上面定义的Token一致),这个接口先要验证,成功之后再注释掉$wechatObj->valid(); 这行,同时去掉//$wechatObj->responseMsg();这行的注释.

消息接口就可以使用了,发个消息试试看吧？
