PHP Get token implementation code (WeChat)

This article brings you the content is about PHP to obtain token code implementation (), there is a certain reference value, the need for friends can refer to, I hope to help you.

Interface Invocation Request Description

{"Access_token": "Access_token", "expires_in": 7200}

Parameter description

Parameters	Description
Access_token	The credential that gets to
Expires_in	Voucher valid time, unit: seconds

The above is the public number to obtain Access_token documentation, this chapter simply describes how PHP gets tokens and places to be aware

1. The prepared parameters need the public number of the AppID and secret the 2 information, but also note that the secret changes you save also need to change, so do not suggest changes, save OK.

2. Need to set the white list, can be based on the server's IP address to obtain, if you do not know, it does not matter, because you can according to the error of the interface to know your IP and then set it in.

3.access_token the number of times a day is valid, remember the word is 2K times a day, but a token of the validity of 2 hours, so we must cache a token for 2 hours, so that it does not exceed the number of calls to the interface.

<?php Public Function Getaccesstoken ($appid, $secret) {$url = "https://api.weixin.qq.com/cgi-bin/token?grant_t        ype=client_credential&appid={$appid}&secret={$secret} ";        $res = $this->curl_get ($url);        $res = Json_decode ($res, 1);        if ($res [' Errcode ']!=0) throw new Exception ($res [' errmsg ']);    return $res [' Access_token ']; The Public Function Curl_get ($url) {$headers = Array (' user-agent:mozilla/5.0 (Windows NT 6.1; Win64;        x64) applewebkit/537.36 (khtml, like Gecko) chrome/58.0.3029.81 safari/537.36 ');        $oCurl = Curl_init ();            if (Stripos ($url, "https://")!==false) {curl_setopt ($oCurl, Curlopt_ssl_verifypeer, FALSE);            curl_setopt ($oCurl, Curlopt_ssl_verifyhost, FALSE); curl_setopt ($oCurl, curlopt_sslversion, 1);        CURL_SSLVERSION_TLSV1} curl_setopt ($oCurl, Curlopt_timeout, 20);        curl_setopt ($oCurl, Curlopt_url, $url);   curl_setopt ($oCurl, Curlopt_httpheader, $headers);     curl_setopt ($oCurl, Curlopt_returntransfer, 1);        $sContent = curl_exec ($oCurl);        $aStatus = Curl_getinfo ($oCurl);        Curl_close ($oCurl);        if (Intval ($aStatus ["Http_code"]) {return $sContent; ==200)        }else{return false; }    }

The above is the code for PHP to get tokens, relatively difficult than the lower.
