Share an experience in PHP WeChat development. Sometimes when a project or project needs to be shared on WeChat and then do a series of events, then we need to get the WeChat sharing action, which means we already know that the current thing has been has been shared, then it is obviously not possible to use WeChat's default sharing. We need to configure WeChat sharing ourselves. When users share, they follow our predetermined procedures, so we can easily achieve what they do after sharing.

On the page side, there is mainly a js as follows:

<script type="text/javascript" src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
 
<script>
wx.config({
   debug: false, // 開啟調(diào)試模式,調(diào)用的所有api的返回值會(huì)在客戶端alert出來，若要查看傳入的參數(shù)，可以在pc端打開，參數(shù)信息會(huì)通過log打出，僅在pc端時(shí)才會(huì)打印。
   appId: &#39;{$appid}&#39;, // 必填，公眾號(hào)的唯一標(biāo)識(shí)
   timestamp:{$timestamp} , // 必填，生成簽名的時(shí)間戳
   nonceStr: &#39;{$nonceStr}&#39;, // 必填，生成簽名的隨機(jī)串
   signature: &#39;{$signature}&#39;,// 必填，簽名，見附錄1
   jsApiList: [&#39;onMenuShareAppMessage&#39;,&#39;onMenuShareTimeline&#39;] // 必填，需要使用的JS接口列表，所有JS接口列表見附錄2
 });
 
 wx.ready(function(){
  //分享給朋友
  wx.onMenuShareAppMessage({
    title: {$title}, // 分享標(biāo)題 此處$title可在控制器端傳遞也可在頁(yè)面?zhèn)鬟f 頁(yè)面?zhèn)鬟f講解在下面哦
    desc: {$desc}, //分享描述
    link: {$link}, // 分享鏈接
    imgUrl: {$imgurl}, // 分享圖標(biāo)
    type: &#39;&#39;, // 分享類型,music、video或link，不填默認(rèn)為link
    dataUrl: &#39;&#39;, // 如果type是music或video，則要提供數(shù)據(jù)鏈接，默認(rèn)為空
    success: function () {
       alert(&#39;分享成功&#39;);
    },
    cancel: function () {
      // 用戶取消分享后執(zhí)行的回調(diào)函數(shù)
      // alert(&#39;取消分享&#39;);
    }
  });
  //分享到朋友圈
   wx.onMenuShareTimeline({
    title: {$title}, // 分享標(biāo)題
    desc: {$desc}, // 分享描述
    link: {$link}, // 分享鏈接
    imgUrl: {$imgurl}, // 分享圖標(biāo)
    success: function () {
      // 用戶確認(rèn)分享后執(zhí)行的回調(diào)函數(shù)
    },
    cancel: function () {
      // 用戶取消分享后執(zhí)行的回調(diào)函數(shù)
    }
  });
 });
 
</script>

When wx.config is configured, the program will proceed to the following sharing. For debugging here, you can change false to true if configured properly. Then if the normal pop-up ok and other information are not configured, changing this to true will not have any pop-up effect

wx.config requires four parameters from the controller, namely appId, timestamp, nonceStr, and signature; control The device code is as follows:

<？php
 
$jssdk = new \Home\Util\JSSDK(C(&#39;APPID&#39;), C(&#39;SECRET&#39;));//此處C里面的東西為你所使用的公眾號(hào)的appid和secret，這倆個(gè)東西可在微信公眾平臺(tái)獲取到 不詳細(xì)解釋 找不到追加評(píng)論（講解） JSSDK文件代碼在下
$signPackage = $jssdk->GetSignPackage();
 
$this->assign(&#39;appid&#39;,$signPackage["appId"]);
$this->assign(&#39;timestamp&#39;,$signPackage["timestamp"]);
$this->assign(&#39;nonceStr&#39;,$signPackage["nonceStr"]);
 $this->assign(&#39;signature&#39;,$signPackage["signature"]);

Wx.config is configured here, and you can also pass in title and other information. Here is an example

$this->assign('title', $title);

JSSDK file code:

<?php
namespace Home\Util;
use Think\Controller;
class JSSDK{
 private $appId;
 private $appSecret;
 public function __construct($appId, $appSecret) {
  $this->appId = $appId;

  $url = "$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

At this point, WeChat sharing comes to an end, but there are flaws. What if we want to dynamically pass parameters? That is to say, when the page information wx. After config is configured, what should we do if we suddenly want to reassign variable information such as $title?

We can write sharing in a method as follows (rough code):

<script>
var zl= function (title,link,imgurl,desc){
 wx.ready(function(){
  //分享給朋友
  wx.onMenuShareAppMessage({
    title: title, // 分享標(biāo)題
    desc: desc, //分享描述
    link: link, // 分享鏈接
    imgUrl: imgurl, // 分享圖標(biāo)
    type: &#39;&#39;, // 分享類型,music、video或link，不填默認(rèn)為link
    dataUrl: &#39;&#39;, // 如果type是music或video，則要提供數(shù)據(jù)鏈接，默認(rèn)為空
    success: function () {
       alert(&#39;分享成功&#39;);
    },
    cancel: function () {
      // 用戶取消分享后執(zhí)行的回調(diào)函數(shù)
      // alert(&#39;取消分享&#39;);
    }
  });
  //分享到朋友圈
   wx.onMenuShareTimeline({
    title: title, // 分享標(biāo)題
    desc: desc, // 分享描述
    link: link, // 分享鏈接
    imgUrl: imgurl, // 分享圖標(biāo)
    success: function () {
      // 用戶確認(rèn)分享后執(zhí)行的回調(diào)函數(shù)
    },
    cancel: function () {
      // 用戶取消分享后執(zhí)行的回調(diào)函數(shù)
      // alert(&#39;已取消分享&#39;);
    }
  });
 });
};
</script>

Explain that the title and other information in the share have been configured when entering the page from the controller. Then configure After that, I want to give the title value again on the page, so this is the method. The page copy code is as follows

<script>
zl(title,link,imgurl,desc);
</script>

easy. If you want to know more about this and other functions on WeChat, you can Reference Manual

The above is the entire content of this article. I hope it will be helpful to everyone's learning, and I also hope that everyone will support the PHP Chinese website.
