一.调用第三方接口的方法

function https_request($url,$type='get',$res='json',$data = ''){ //1.初始化curl $curl = curl_init(); //2.设置curl的参数 curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST,2); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); if ($type == "post"){ curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); } //3.采集 $output = curl_exec($curl); //4.关闭 curl_close($curl); if ($res == 'json') { return json_decode($output,true); } }

二.获取用户的openid

function getBaseInfo(){ $appid = "我的ID"; $redirect_uri = urlencode("http://www.XXXXXXX.com/XXXXX/XXXXXX.php/Index/getUserOpenId"); $url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=".$appid."&redirect_uri=".$redirect_uri."&response_type=code&scope=snsapi_base&state=614#wechat_redirect"; header('location:'.$url); }

三.获取用户的access_token

function getUserOpenId(){ $appid = "我的ID"; $appsecret = "我的secret"; $code=$_GET['code']; //2.获取到网页授权的access_token $url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=".$appid."&secret=".$appsecret."&code=".$code."&grant_type=authorization_cod"; //3.拉取用户的opendi $res = $this->https_request($url); var_dump($code); var_dump("
"); var_dump($url); var_dump("
"); dump($res); }

获取不到网页授权接口的code,打印三个值结果如下:

NULL string(5) " " string(149) "https://api.weixin.qq.com/sns/oauth2/access_token?appid=我的ID &secret=我的secret&code=&grant_type=authorization_cod" string(5) " " array(2) { ["errcode"]=> int(41008) ["errmsg"]=> string(47) "missing code, hints: [ req_id: 3MmDtA0251s113 ]" }

问题已经找到，相信很多人和我一样没发现问题在哪。如下所示，应该是code。从官网拷贝的链接，不知道咋弄的，少了一个字母...然而这里不需要拼装参数，所以一直没发现...
