第三方平台开发流程

image.png

整个流程是第三方平台 提供一个授权的页面供公众号|小程序管理员进行授权, 授权后第三方平台将获得 授权方(公众号|小程序)的以下信息

authorization_info //授权信息
authorizer_appid  //授权方appid
authorizer_access_token   //access_token
expires_in
authorizer_refresh_token
func_info  // 授权的权限列表

然后用获取的 authorizer_appid 及authorizer_access_token 代授权方调用相应的接口

按开放平台的文档上说, 公众号授权第三方平台管理后,微信服务器会将粉丝发给公众号的消息，以及微信服务器发给公众号的事件推送（如自定义菜单点击事件、粉丝取消关注通知等），发给开发者服务器（会发送到公众号消息与事件接收URL，详见申请资料说明页）上 . 也就是说第三方平台会接管消息接口 ,

关键参数

1. component_verify_ticket
   第三方平台创建审核通过后, 微信服务器每10分钟推送给第三方平台

<xml>
<AppId> </AppId>
<CreateTime>1413192605 </CreateTime>
<InfoType> </InfoType>
<ComponentVerifyTicket> </ComponentVerifyTicket>
</xml>

2. component_access_token
   第三方平台的所有接口都需要此token调用, 生成方式:

url:https://api.weixin.qq.com/cgi-bin/component/api_component_token
post:
{
    "component_appid": "appid_value",
    "component_appsecret": "appsecret_value",
    "component_verify_ticket": "ticket_value"
}
return:
{
    "component_access_token": "61W3mEpU66027wgNZ_MhGHNQDHnFATkDa9-2llqrMBjUwxRSNPbVsMmyD-yq8wZETSoE5NQgecigDrSHkPtIYA",
    "expires_in": 7200
}

3. pre_auth_code
   预授权码, 授权时的参数, 生成方式:

url:
https://api.weixin.qq.com/cgi-bin/component/api_create_preauthcode?component_access_token=xxx
post:
{
    "component_appid": "appid_value"
}

return:
{
    "pre_auth_code": "Cx_Dk6qiBE0Dmx4EmlT3oRfArPvwSQ-oa3NL_fwHM7VI08r52wazoZX2Rhpz1dEw",
    "expires_in": 600
}

4. auth_code
   授权回调参数, 生成方式

url:
 https://mp.weixin.qq.com/safe/bindcomponent?action=bindcomponent&auth_type=3&no_scan=1&component_appid=xxxx&pre_auth_code=xxxxx&redirect_uri=xxxx&auth_type=xxx&biz_appid=xxxx#wechat_redirect

return :
https://redirect_url/?auth_code=xxx&expires_in=600

5. authorizer_appid , authorizer_access_token..
   用户授权后 通过回调的 auth_code ,expires_in 获取授权方的appid , access_token 用于代授权方公众号|小程序调用接口

url:
https://api.weixin.qq.com/cgi-bin/component/api_query_auth?component_access_token=xxxx
post:
{
    "component_appid": "appid_value",
    "authorization_code": "auth_code"
}

return :
{
    "authorization_info": {
        "authorizer_appid": "wxf8b4f85f3a794e77",
        "authorizer_access_token": "QXjUqNqfYVH0yBE1iI_7vuN_9gQbpjfK7hYwJ3P7xOa88a89-Aga5x1NMYJyB8G2yKt1KCl0nPC3W9GJzw0Zzq_dBxc8pxIGUNi_bFes0qM",
        "expires_in": 7200,
        "authorizer_refresh_token": "dTo-YCXPL4llX-u1W1pPpnp8Hgm4wpJtlR6iV0doKdY",
        "func_info": [
            {
                "funcscope_category": {
                    "id": 1
                }
            },
            {
                "funcscope_category": {
                    "id": 2
                }
            },
            {
                "funcscope_category": {
                    "id": 3
                }
            }
        ]
    }
}

6. 刷新 authorizer_access_token

url:
https:// api.weixin.qq.com /cgi-bin/component/api_authorizer_token?component_access_token=xxxxx

post:
{
    "component_appid": "appid_value",
    "authorizer_appid": "auth_appid_value",
    "authorizer_refresh_token": "refresh_token_value"
}
reutrn :
{
    "authorizer_access_token": "aaUl5s6kAByLwgV0BhXNuIFFUqfrR8vTATsoSHukcIGqJgrc4KmMJ-JlKoC_-NKCLBvuU1cWPv4vDcLN8Z0pn5I45mpATruU0b51hzeT1f8",
    "expires_in": 7200,
    "authorizer_refresh_token": "BstnRqgTJBXb9N2aJq6L5hzfJwP406tpfahQeLNxX0w"

"option_name": "option_name_value",
"option_value":"option_value_value"
}
return:
{
"errcode":0,
"errmsg":"ok"
}

10. 授权通知
    公众号|小程序在授权页进行操作时, 微信服务器将事件推送给第三方平台设定的url

• . 授权成功

<xml>
<AppId>第三方平台appid</AppId>
<CreateTime>1413192760</CreateTime>
<InfoType>authorized</InfoType>
<AuthorizerAppid>公众号appid</AuthorizerAppid>
<AuthorizationCode>授权码（code）</AuthorizationCode>
<AuthorizationCodeExpiredTime>过期时间</AuthorizationCodeExpiredTime>
<PreAuthCode>预授权码</PreAuthCode>

<xml>

• . 取消授权

<xml>
<AppId>第三方平台appid</AppId>
<CreateTime>1413192760</CreateTime>
<InfoType>unauthorized</InfoType>
<AuthorizerAppid>公众号appid</AuthorizerAppid>

</xml>

• . 更新授权

12. 拉取当前所有已授权的帐号基本信息

url:
https://api.weixin.qq.com/cgi-bin/component/api_get_authorizer_list?component_access_token=COMPONENT_ACCESS_TOKEN
post:
{
    "component_appid": "appid_value",
    "offset": 0,
    "count": 100
}

return:
{
    "total_count": 33,
    "list": [
        {
            "authorizer_appid": "authorizer_appid_1",
            "refresh_token": "refresh_token_1",
            "auth_time": "auth_time_1"
        },
        {
            "authorizer_appid": "authorizer_appid_2",
            "refresh_token": "refresh_token_2",
            "auth_time": "auth_time_2"
        }
    ]
}
