Senparc.Weixin.MP SDK 微信公衆平臺開發教程(十一):高級接口說明

 這裏所說的高級接口是指面向經過認證的服務號開通的高級功能。php

    高級功能大體能夠分類爲:html

  • 用戶接口
  • 分組接口
  • 客服接口(有別於以前介紹的多客服
  • 羣發接口
  • 多媒體接口
  • 二維碼接口
  • 模板消息接口(不是全部帳號均可開通)
  • OAuth2.0(相對比較複雜,後面會有專門介紹)

  以上全部的接口都包含在Senparc.Weixin.MP.AdvancedAPIs命名空間下。api

一些共同的操做

  幾乎全部的高級接口都須要用到AccessToken來通信(注意,下面若是沒有特殊說明的接口都須要這個AccessToken,但並不是全部),所以多數會有一個AccessToken參數傳入,有關AccessToken獲取和操做的方式見Senparc.Weixin.MP SDK 微信公衆平臺開發教程(八):通用接口說明數組

客服接口

  說明一下,這裏的客服接口和以前的「多客服」是有差異的,以前介紹的多客服是把用戶對話狀態切換到多客服客,消息發送到專門的多客服戶端,這個對話是由用戶主動發起的。而這裏的「客服」其實是指在任意時間,主動推送消息給指定過的用戶(用戶在48小時內有過互動),對話不須要由用戶主動發起。微信公衆平臺

二維碼接口

  使用二維碼接口能夠方便地建立和驗證二維碼。所建立的二維碼用於讓用戶關注或識別掃描的場景。

  源文件文件夾:Senparc.Weixin.MP/AdvancedAPIs/QrCode

  源代碼中相關方法以下:

模板消息接口

  模板消息相似於短信通知,它遵循必定的模板格式(和圖文信息等不同),不是每一個經過驗證的服務號均可以獲取。

  源文件文件夾:Senparc.Weixin.MP/AdvancedAPIs/TemplateMessage

  源代碼中相關方法以下:

複製代碼
namespace Senparc.Weixin.MP.AdvancedAPIs
{
    /// <summary>
    /// 模板消息接口
    /// </summary>
    public static class Template
    {
        public static WxJsonResult SendTemplateMessage<T>(string accessToken, string openId, string templateId, string topcolor, T data)
        {
            const string urlFormat = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token={0}";
            var msgData = new TempleteModel()
            {
                template_id = templateId,
                topcolor = topcolor,
                touser = openId,
                data = data
            };
            return CommonJsonSend.Send<WxJsonResult>(accessToken, urlFormat, msgData);
        }
    }

OAuth2.0接口

  OAuth接口用於安全驗證使用微信內嵌瀏覽器訪問的用戶的身份(例如獲取OpenId)

  源文件文件夾:Senparc.Weixin.MP/AdvancedAPIs/OAuth

  相比其餘接口OAuth2.0略微複雜,相關內容將在下一篇專門進行介紹:《Senparc.Weixin.MP SDK 微信公衆平臺開發教程(十二):OAuth2.0說明
