PHP implements the method of sending template messages in WeChat applet (code)-PHP Tutorial-php.cn

The content of this article is about the method (code) of php implementing WeChat applet to send template messages. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

The WeChat address is:

https://api.weixin.qq.com/cgi-bin/message/wxopen/template/send?access_token=ACCESS_TOKEN

Copy after login

The relevant parameters are

##parameters Required illustrate touser yes The openid of the recipient (user) template_id yes The id of the template message to be delivered page no The jump page after clicking the template card is limited to pages within this mini program. Supports parameters, (example index?foo=bar). If this field is not filled in, the template will not jump. form_id yes In the form submission scenario, it is the formId brought by the submit event; in the payment scenario, it is the prepay_id of this payment data yes Template content, if not filled in, an empty template will be issued color no The color of the font of the template content. If not filled in, the default is black [Abandoned] emphasis_keyword no Keywords that need to be amplified in the template. If not filled in, the amplification will be disabled by default

The basic parameters and addresses are tested above. Some people may wonder where to get form_id, openid, tmeplate_id. Let’s briefly talk about it first.

form_id can be obtained by Provided by the front end, the front end can submit the form on each button to obtain the form_id and give it to the back end, and at the same time, the back end gets the relevant openid. What is recommended here is that the front end provides as much as possible to the back end, that is, each button provides an id to the back end. The form_id is valid for 7 days. Regardless of whether the operator uses it or not, it is better to have more than less.

template_id is the template id, which can be obtained from the template message by logging into the WeChat applet background.

After we know these parameters, the developer will definitely want to test it immediately, and then let the front end provide the form_id. Here are the next two pitfalls

First Pitfall: The form_id obtained by the computer cannot be used

The second pitfall: the form_id needs to be obtained from the real phone, but the real phone must also be online. For projects on, if the local test is not launched online, you will be prompted to verify the form_id. WeChat does not explain this point of attention, that is, it needs to be tested online after the review is successfully released.

Next let’s talk about the back-end code

curl_get($url); $res = json_decode($res,1); return $res['access_token']; } //获取模板消息内容主体 //因为是测试所以写死，大家可以通过传参的方式获取 public function getMsg($openid,$template_id,$form_id,$emphasis_keyword='keyword1'){ $data['data']= ['keyword1'=>['value'=>'test1','color'=>''],'keyword2'=>['value'=>'test2','color'=>''],'keyword3'=>['value'=>'test1','color'=>'']];//内容主体 $data['touser'] = $openid;//用户的openid $data['template_id'] = $template_id;//从微信后台获取的模板id $data['form_id'] = $form_id;//前端提供给后端的form_id $data['page'] = 'pages/index/index';//小程序跳转页面 $data['emphasis_keyword'] = $emphasis_keyword;//选择放大的字体 return $data; } public function send($appid,secret,$openid,$template_id,$form_id){ $access_token = $this->getAccessToken($appid,secret); $send_url = 'https://api.weixin.qq.com/cgi-bin/message/wxopen/template/send? access_token=' . $access_token; $data = $this->getMsg($openid,$template_id,$form_id); $str = $this->curl_post($send_url,json_encode($data)); $str = json_decode($str,1); return $str; } public function curl_post($url, $fields, $data_type='text') { $cl = curl_init(); if(stripos($url, 'https://') !== FALSE) { curl_setopt($cl, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($cl, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($cl, CURLOPT_SSLVERSION, 1); } curl_setopt($cl, CURLOPT_URL, $url); curl_setopt($cl, CURLOPT_RETURNTRANSFER, 1 ); curl_setopt($cl, CURLOPT_POST, true); curl_setopt($cl, CURLOPT_POSTFIELDS, $fields); $content = curl_exec($cl); $status = curl_getinfo($cl); curl_close($cl); if (isset($status['http_code']) && $status['http_code'] == 200) { if ($data_type == 'json') { $content = json_decode($content); } return $content; } else { return FALSE; } } public function curl_get($url, $data_type='text') { $cl = curl_init(); if(stripos($url, 'https://') !== FALSE) { curl_setopt($cl, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($cl, CURLOPT_SSL_VERIFYHOST, FALSE); curl_setopt($cl, CURLOPT_SSLVERSION, 1); } curl_setopt($cl, CURLOPT_URL, $url); curl_setopt($cl, CURLOPT_RETURNTRANSFER, 1 ); $content = curl_exec($cl); $status = curl_getinfo($cl); curl_close($cl); if (isset($status['http_code']) && $status['http_code'] == 200) { if ($data_type == 'json') { $content = json_decode($content); } return $content; } else { return FALSE; } } punblic function index(){ $appid = 'xxx';//小程序appid $openid = 'xxx';//接收用户的openid $template_id = 'xxx';//从微信后台获取的模板id $form_id = 'xxx';//七天内的formid $data = $this->send($appid,secret,$openid,$template_id,$form_id); var_dump($data);//打印测试结果 }
