介绍

在做微信开放平台第三方应用开发的时候，每次都要登录到微信开放平台中操作，如果多了的话，很不方便，所以想到集成到自己后台操作，这样就可以同时管理n个开放平台里面的n个第三方应用了。

犹豫代码涉及逻辑会比较复杂，所以只提取了相关部分。

步骤

获取cookie和token

在操作第三方之前，需要获取token和cookie，获取方式如下代码：

<?php

use App\Models\WxOpen;
use EasyWeChat\Factory;
use Illuminate\Support\Facades\Cache;

    public function __construct()

        // 首先要获取open对象
        $this->openApp = $this->getOpenApp();

使用方式

调用 $appList = WxOpenUtils::getInstance()->appList();来获取token和cookie.

后面请求中要带上token和cookie，第三方操作中全部大写的代表参数，用到的几个变量分别如下，

$appList = WxOpenUtils::getInstance()->appList();

COOKIE:$appList['cookie'] . ';__CURRENT_TOKEN__=' . $appList['token'];

TOKEN:$appList['token']

APPID: POST添加应用返回该应用的APPID

第三方操作

拿到token和cookie后，接下来的工作就比较简单啦，这里只提供接口和参数，自己去实现吧。

POST添加应用

地址:

 https://open.weixin.qq.com/cgi-bin/component_acct?action=create_component&token=TOKEN

请求头：

referer:https://open.weixin.qq.com/wxaopen/createThirdAccount?token=TOKEN&lang=;
origin:https://open.weixin.qq.com;

数据包:

{
    "name":"应用名称",
    "desc":"描述",
    "icon_url":"图片地址",
    "official_site_url":"首页(随机编个域名吧)",
    "industry_tag_id_list":[
        2001
    ],
    "type":0
}

添加应用成功会返回该应用的APPID,把它取出来后面要用。

GET获取第三方详情

地址:

https://open.weixin.qq.com/cgi-bin/component_acct?action=detail&t=manage/plugin_detail&token=TOKEN&appid=APPID&f=json';

POST修改ip和公众号

地址:

https://open.weixin.qq.com/cgi-bin/component_acct?action=detail&t=manage/plugin_detail&token=TOKEN&appid=APPID;

请求头：

referer:https://open.weixin.qq.com/wxaopen/serviceprovider/APPID?token=TOKEN;
origin:https://open.weixin.qq.com;

数据包:

{
    "token":TOKEN,
    "action":"direct_modify",
    "white_acct":"公众号原始id",
    "white_ip":"ip白名单",
}

POST修改权限集(这一步就是添加公众号网页授权)

地址:

https://open.weixin.qq.com/cgi-bin/component_acct?action=modify_funcscopecategory&category_list=4

请求头：

referer: https://open.weixin.qq.com/wxaopen/authoritylist/APPID?token=TOKEN&lang=zh_CN';
origin:https://open.weixin.qq.com;

数据包:

category_list=4&appid=APPID&token=TOKEN

POST修改开发资料

地址:

https://open.weixin.qq.com/cgi-bin/component_acct?action=modify_dev_info&token=TOKEN&appid=APPID

请求头：

referer: https://open.weixin.qq.com/wxaopen/createThirdAccount/modifyDevInfo?appId=APPID&token=TOKEN;
origin:https://open.weixin.qq.com;

数据包:

{
    "token":"这个token是消息加解密token",
    "auth_domain":"授权发起域名",
    "allow_container_domain":false,
    "ticket_url":"授权事件接收URL",
    "msg_url":"消息与事件接收URL",
    "white_ip":"白名单IP",
    "white_acct":[
        "公众号ID"
    ],
    "symmetric_key":"消息加解密Key",
    "sns_domain":"我们用的分享域名;号分割",
    "wxa_server_domain":"",
    "jump_h5_domain":"",
    "ticket_url_qbase":{
        "enable":false,
        "container":{
            "env":"",
            "path":"",
            "service":""
        },
        "function":{
            "env":"",
            "function_name":""
        }
    },
    "msg_url_qbase":{
        "enable":false,
        "container":{
            "env":"",
            "path":"",
            "service":""

            "env":"",
            "function_name":""
        }
    }
}

POST删除第三方

地址:

https://open.weixin.qq.com/cgi-bin/component_acct?action=del_component;

请求头：

referer:  https://open.weixin.qq.com/cgi-bin/applist?t=manage/list&page=0&num=20&openapptype=2048&token=TOKEN;
