获取微信小程序scheme码，适用于短信、邮件、外部网页等拉起小程序的业务场景

 

这里属于HTTPS调用    贴它！

注意：access_token参数在URL中体现，其它参数写在POST请求的body中！

<?php

/**
 * 获取access_token
 * $appid:开发者ID(AppID)
 * $appsecret：开发者密码(AppSecret)
 *
 * 返回access_token、有效时间
 */
function wx_xcx_code($appid, $appsecret){

    $access_info = json_decode(file_get_contents($access_url),true);
    return $access_info;
}


/**
 * 拼接接口及请求参数  调用POST请求 返回结果
 */
function  getUrlScheme(){
    $access_token = wx_xcx_code("开发者ID-AppID", "开发者密码-AppSecret");
    $access_token = $access_token['access_token']; // 加个判断，是否获取成功
    $url = "https://api.weixin.qq.com/wxa/generatescheme?access_token=" . $access_token;
