微信小程序 微信小程序获取openID

//getOpenid.php文件(拼接url返回数据)

<?php

include_once 'requestion.php';

include_once 'config.php';

getOpenid($appid, $appSecret);

function getOpenid($appid, $appSecret) {

    $code = $_GET['code'];//小程序传来的code值 

    $wxUrl = 'https://api.weixin.qq.com/sns/jscode2session?appid=%s&secret=%s&js_code=%s&grant_type=authorization_code';

    $getUrl = sprintf($wxUrl, $appid, $appSecret, $code);//把appid，appsecret，code拼接到url里

    $result = curl_get($getUrl);//请求拼接好的url

    //return $result;

    $wxResult = json_decode($result, true);   

    if (empty($wxResult)) {

       echo '获取openid时异常，微信内部错误';

    } else {

        $loginFail = array_key_exists('errcode', $wxResult);

        if ($loginFail) {//请求失败

            var_dump($wxResult);

        } else {//请求成功

            $openid = $wxResult['openid'];

            $text=json_encode($wxResult);

            $myfile = fopen("hc.txt", "w") or die("Unable to open file!");

            fwrite($myfile, $text);

            fclose($myfile);

            echo $openid;

        }

    }

}

//requestion.php页面(封装了get和post请求)

<?php

//发送get请求

function curl_get($url, &$httpCode = 0) {

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    //不做证书校验,部署在linux环境下请改为true

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);

    $file_contents = curl_exec($ch);

    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

    curl_close($ch);

    return $file_contents;

}

//发送post请求

function curlPost($url,$data)

{

    $ch = curl_init();

    $params[CURLOPT_URL] = $url;    //请求url地址

    $params[CURLOPT_HEADER] = FALSE; //是否返回响应头信息

    $params[CURLOPT_SSL_VERIFYPEER] = false;

    $params[CURLOPT_SSL_VERIFYHOST] = false;

    $params[CURLOPT_RETURNTRANSFER] = true; //是否将结果返回

    $params[CURLOPT_POST] = true;

    $params[CURLOPT_POSTFIELDS] = $data;

    curl_setopt_array($ch, $params); //传入curl参数

    $content = curl_exec($ch); //执行

    curl_close($ch); //关闭连接

    return $content;

}

//config.php页面(配置文件)

<?php

 $appid = 'APPID';//小程序的appid

 $appSecret = 'SECRET';// 小程序的$appSecret
