完美利用Yii2微信后台开发的系列总结
网上有很多关于YII2.0微信开发教程，但是太过复杂凌乱，所以今天在这里给大家整理总结利用Yii2微信后台开发的系列了，给需要的小伙伴们参考。
一：接入微信
Yii2后台配置
1.在app/config/params.php中配置token参数
return [
//微信接入
'wechat' =>[
'token' => 'your token',
],
];
2.在app/config/main.php中配置路由
因为接口模块使用的RESTful API，所以需要定义路由规则。
'urlManager' => [
'enablePrettyUrl' => true,
'enableStrictParsing' => true,
'showScriptName' => false,
'rules' => [
[
'class' => 'yii\rest\UrlRule',
'controller' => 'wechat',
'extraPatterns' => [
'GET valid' => 'valid',
],
],
],
],
3.在app/controllers中新建WechatController
<?php
namespace api\controllers;
use Yii;
use yii\rest\ActiveController;
class WechatController extends ActiveController
{
public $modelClass = '';
public function actionValid()
{
$echoStr = $_GET["echostr"];
$signature = $_GET["signature"];
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
//valid signature , option
if($this->checkSignature($signature,$timestamp,$nonce)){
echo $echoStr;
}
}
private function checkSignature($signature,$timestamp,$nonce)
{
// you must define TOKEN by yourself
$token = Yii::$app->params['wechat']['token'];
if (!$token) {
echo 'TOKEN is not defined!';
} else {
$tmpArr = array($token, $timestamp, $nonce);
// use SORT_STRING rule
sort($tmpArr, SORT_STRING);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
}
}
微信公众号后台配置
在微信公众号后台配置URL和Token，然后提交验证即可。
URL:http://app.demo.com/wechats/valid
Token:your token
二：获取用户信息
用户表设计
https://api.weixin.qq.com/cgi-bin/ticket/getticket?type=jsapi&access_token=".$accessToken;
$res = json_decode(self::curlGet($url));
$ticket = $res->ticket;
if ($ticket) {
$redis->set('wechat:jsapi_ticket', $ticket);
$redis->expire('wechat:jsapi_ticket', 7000);
}
}
return $ticket;
}
public static function getAccessToken() {
//使用Redis缓存 access_token
$redis = Yii::$app->redis;
$redis_token = $redis->get('wechat:access_token');
if ($redis_token) {
$access_token = $redis_token;
} else {
$appid = Yii::$app->params['wechat']['appid'];
$appsecret = Yii::$app->params['wechat']['appsecret'];
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appid."&secret=".$appsecret;
$res = json_decode(self::curlGet($url));
$access_token = $res->access_token;
if ($access_token) {
$redis->set('wechat:access_token', $access_token);
$redis->expire('wechat:access_token', 7000);
}
}
return $access_token;
}
public static function curlGet($url = '', $options = array()){
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
if (!empty($options)) {
curl_setopt_array($ch, $options);
}
//https请求 不验证证书和host
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
public static function curlPost($url = '', $postData = '', $options = array()){
if (is_array($postData)) {
$postData = http_build_query($postData);
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch, CURLOPT_TIMEOUT, 30); //设置cURL允许执行的最长秒数
if (!empty($options)) {
curl_setopt_array($ch, $options);
}
//https请求 不验证证书和host
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
public static function createNonceStr($length = 16){
$chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
$str = '';
for ($i = 0; $i<$length; $i++){
$str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);
}
return $str;
}
}
2.获取config参数接口
public function actionConfig(){
if (isset($_REQUEST['url'])) {
$url = $_REQUEST['url'];
//微信支付参数
$appid = Yii::$app->params['wechat']['appid'];
$mchid = Yii::$app->params['wechat']['mchid'];
$key = Yii::$app->params['wechat']['key'];
$wx_pay = new WechatPay($mchid, $appid, $key);
$package = $wx_pay->getSignPackage($url);
$result['error'] = 0;
$result['msg'] = '获取成功';
$result['config'] = $package;
} else {
$result['error'] = 1;
$result['msg'] = '参数错误';
}
return $result;
}
以上就是利用Yii2微信后台开发全部过程及示例代码，希望本文对大家基于php的微信公众平台开发有所帮助。
