<code>class Wechat_base_api{ private $appid='wx5d4b7d2e8bfd5793'; private $appsecret='4379ef7213c36eae5dc2ab91f9f6aced'; //构造函数 public function __construct($appid,$appsecret) { $this->appid = $appid; $this->appsecret = $appsecret; } //获取access_token(支持自动更新凭证) public function get_access_token() { $this->last_time = 1408851194; $access_token = "jIGpovtFGZDXCB_K2vqDPTA05zP7VWZaKIHXC_qZDqEiSGONWfCzQ45fI9aksl2L188yhtPpNB61iOBS4TTtgw"; if(time() > ($this->last_time + 7200)) { //GET请求的地址 $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={$this->appid}&secret={$this->appsecret}"; $access_token_Arr = $this->https_request($url); $this->last_time = time(); return $access_token_Arr['access_token']; } return $access_token; }</code>

1.没有语法错误
2.这是谁家的id和secret...
过期时间写死,会导致不停请求微信接口,可能会达到接口请求上限
access_token也是写死,当达到接口请求上限后,返回都是过期错误的access_token
说到底,access_token没有缓存起来。
下面这个是根据微信提供的示例代码更改改过的:
<code><?php /** * Created by PhpStorm. * User: T.H * Date: 12/9/2015 * Time: 9:59 AM */ class WxApi { /** * 填你的AppId * @var string */ private $appId = ''; /** * 填你的Secret * @var string */ private $appSecret = ''; /** * 填你的 access_token 缓存文件存存放的位置 * @var string */ private $file_path = '/var/wx/AccessToken.json'; /** * WxAccessToken constructor. * @param string $appId * @param string $appSecret * @param string $file_path */ public function __construct($appId = '', $appSecret = '', $file_path = '') { //初始化 $this->appId = $appId ? $appId : $this->appId; $this->appSecret = $appSecret ? $appSecret : $this->appSecret; $this->file_path = $file_path ? $file_path : $this->file_path; } /** * 获取微信AccessToken * @return mixed */ private function getAccessToken() { $data = json_decode(file_get_contents($this->file_path)); if ($data->expire_time appId&corpsecret=$this->appSecret"; // 其它类型公众号使用这个URL获取access_token $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=$this->appId&secret=$this->appSecret"; //访问微信接口,拉取access_token等信息 $res = json_decode($this->httpGet($url)); //提取出access_token $access_token = $res->access_token; //判断access_token是否存在,存在保存到本地文件中 if ($access_token) { $data->expire_time = time() + 7190; $data->access_token = $access_token; $fp = fopen($this->file_path, "w"); fwrite($fp, json_encode($data)); fclose($fp); } } else { //本地存储的access_token没有过期 $access_token = $data->access_token; } //返回 return $access_token; } /** * 拉取数据 * @param $url * @return mixed|string */ private function httpGet($url) { //本地请求,则跳过请求 if('127.0.0.1' == $_SERVER['SERVER_ADDR']){ return ''; } $curl = curl_init(); curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); curl_setopt($curl, CURLOPT_TIMEOUT, 500); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($curl, CURLOPT_URL, $url); $res = curl_exec($curl); curl_close($curl); return $res; } }</code>
微信官方文档中的 PHP 代码,感觉坑比较多,自己一个个接口试过去太耗时了(别问我是怎么知道的…)。
因为我们项目中用的是 CI 框架,在 GitHub 中这个项目:https://github.com/dodgepudding/wechat-php-sdk 的基础上稍加改动,就完成了微信的集成。
看这份代码比看官方文档要快,我是这么觉得的…
哥们 你们家的appid 跟appsecret 暴露了!!!
另外 access_token 是有次数限制的
记得缓存下来,不然请求次数过多,会出错的
