申请公众平台 和 公众号 各种参数填写完成！！！ 我这里主要讲的是代码
第一步：前端代码
//这里的代码 对应下面的 html 代码
public function index()
{
$id = $this->request->request('id');
$userinfo = Db::name('user')->field('id,wx_nickname,wx_head_image,openid')->where('id',$id)->find();
if($userinfo){
if($userinfo['openid'] == ''){
// 未授权
$userinfo['is'] = 0;
}else{
//已授权
$userinfo['is'] = 1;
}
$this->view->assign("userinfo", $userinfo);
session('user_info_id',$userinfo['id']);
return $this->view->fetch();
}else{
echo '信息错误';exit;
}
}

{/if}
</div>
{if $userinfo['is'] == 0}

{if $userinfo['is'] == 1}
<div class="authorization" onclick="authorization()">

{/if}
<input type="hidden" value="{$userinfo['id']|htmlentities}" id="user_id" name="id">
</div>
<script src="__CDN__/assets/js/jquery/jquery3.3.1.js"></script>
<script>
function authorization()
{
var appid = '这里写你的appID';
//这里写你的回调地址 也就是获取到code 后台换取 openID 的接口 不要加任何参数
//这里文档中有交代 授权后重定向的回调链接地址， 请使用 urlEncode 对链接进行处理
//原本地址 http://www.baidu.com/api/index/getOpenId
//要改成 http%3A%2F%2Fbaidu.com%2Fapi%2Findex%2FgetOpenId 切记
var redirect_uri = 'http%3A%2F%2Fbaidu.com%2Fapi%2Findex%2FgetOpenId';//示例
window.location.href=`https://open.weixin.qq.com/connect/oauth2/authorize?appid=${appid}&redirect_uri=${redirect_uri}&response_type=code&scope=snsapi_userinfo&state=STATE#wechat_redirect`;
}
</script>
</body>
</html>
第二步。
后端 获取 openID的方法
public function getOpenId()
{
$code = $this->request->get('code');
//第一 根据code 获取openid
$url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=$this->business_appid&secret=$this->business_secret&code=$code&grant_type=authorization_code";
$data = file_get_contents($url);
$arr = json_decode($data, true);
if (isset($arr['openid'])) {
$access_token = $arr['access_token'];
$openid = $arr['openid'];
//获取用户信息
$getUserInfoUrl ="https://api.weixin.qq.com/sns/userinfo?access_token=$access_token&openid=$openid&lang=zh_CN";
$userInfoData = file_get_contents($getUserInfoUrl);
$userInfoArr = json_decode($userInfoData, true);
if(session('user_info_id')){
$isUser = Db::name('user')->where(['openid'=>$userInfoArr['openid'],'id'=>session('user_info_id')])->find();
if($isUser){
$this->error(__('No rows were updated'));
}
Db::startTrans();
try{
$user = Db::name('user')->where('id',session('user_info_id'))->update([
'openid' => $userInfoArr['openid'],
'wx_nickname' => $userInfoArr['nickname'],
'wx_head_image' => $userInfoArr['headimgurl'],
'openid' => $userInfoArr['openid'],
'updatetime' => time()
]);
Db::commit();
}catch(Exception $e){
Db::rollback();
$this->error(__($e->getMessage()));
}
if ($user) {
$this->success();
} else {
$this->error(__('No rows were updated'));
}
}
} else {
$this->error(__('No rows were updated'));
}
}
到这里 就授权成功了
第三发送模版消息
我是用的EasyWeChat.模版消息
模板ID xxxxxxxxxx
开发者调用模板消息接口时需提供模板ID
标题
xxxxx标题
详细内容
{{first.DATA}}.
{{keyword1.DATA}}
{{keyword2.DATA}}
{{remark.DATA}}
在发送时，需要将内容中的参数（{{.DATA}}内为参数）赋值替换为需要的信息
use EasyWeChat\Factory;
public function send()
{
$openid = '这是用户的openid';
$template_id = '这是申请的模版ID';
$data = [
'first'=> '你好，您有一个运输订单取消了，请及时确认！',
'keyword1'=> 'keyword1',
'keyword2'=> 'keyword2',
'remark'=> '订单已取消，请知悉！'//备注
];
$res = $this->template($openid,$template_id,$data);
print_r($res);
}
//发送微信模版消息
public function template($openid,$template_id,$data,$url='',$miniprogram=['appid'=>'','pagepath'=>''])
{
$config = [
'app_id' => '',
'secret' => '',
// 指定 API 调用返回结果的类型：array(default)/collection/object/raw/自定义类名
'response_type' => 'array',
];
$app = Factory::officialAccount($config);
return $app->template_message->send([
'touser' => $openid,
'template_id' => $template_id,
'url' => $url,
'miniprogram' => $miniprogram,
'data' => $data,
]);
}
到这 就完成了
