WeChat development obtains access_token

Method 1 to obtain Access Token:

You can modify it manually here:

https://api.weixin .qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET

The appid and secret we want to use here can be obtained in the test, as shown in the figure below :

Then modify it manually:

https://api.weixin.qq.com/cgi-bin/token? grant_type=client_credential&appid=wxed89d8f74fa6fc51&secret=d4624c36b6795d1d99dcf0547af5443d

Then ask the question, you can see that he returns a json format data

{"access_token":"fNNeJ5DpjmpE8SkZnyeByVP4x pqnZRMRkwlhZ7HZemT_WiULJ2YnpsNr4UgTG4zoJo5uMeOA2hFy2rlzOg-U9hnSpHuUuZMZRgI4ZhDK6KN_OIbNxHvfvdl4_wbW775oWKIdAAAIWU","expires_in": 7200}

Method 2 to obtain Access Token:

Call the program get_token.php, and then upload the file to your own WeChat server and browse By calling get_token.php in the server, you can also get the value of the access token.

get_token.php The code is as follows:

<?php     //原理，就是使用curl函数，发出http请求，获取access_token
    $appid = &#39;wxed89d8f74fa6fc51&#39;;
    $appsecret = &#39;d4624c36b6795d1d99dcf0547af5443d&#39;;
    $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={$appid}&secret={$appsecret}";
    
    //我们使用curl函数
    //初始化
    $ch = curl_init();
    //设置变量
    curl_setopt($ch, CURLOPT_URL,$url); //这意思是，设置好发送的url地址发送到那
    //curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,$url); 这样的意思是对方要不要验证，如果不用则按照下面的即可
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,FALSE); //如果不用验证，这样即可
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,FALSE); //如果不用验证HOST主机这样即可
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); //将curl_exec()获取的信息以文件流的形式返回，而不是直接输出
    //执行
    $output = curl_exec($ch); //返回来的值是一个json格式的值
    //对返回的json结果要将他转为一个数组
    $jsoninfo = json_decode($output,true);
    //测试以下，看下是否拿到返的回数组
    //var_dump($jsoninfo); 
    
    $access_token = $jsoninfo[&#39;access_token&#39;];
