微信小程序-發送模板消息(C#)

步驟一:獲取模板IDhtml

有兩個方法能夠獲取模版ID前端

  1. 經過模版消息管理接口獲取模版ID
  2. 在微信公衆平臺手動配置獲取模版ID

步驟二:頁面的 <form/> 組件,屬性report-submittrue時,能夠聲明爲需發模板消息,此時點擊按鈕提交表單能夠獲取formId,用於發送模板消息。或者當用戶完成支付行爲,能夠獲取prepay_id用於發送模板消息。chrome

步驟三:調用接口下發模板消息json

 

今天重要的說第三步怎麼實現,前面的步驟比較簡單就略過。api

----------------------------------------------------------------------------------------------------服務器

  1. 獲取 access_token微信



後面會在發送模板消息的時候會用到access_token

https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET

  2. 發送模板消息app

   接口地址:(ACCESS_TOKEN 需換成上文獲取到的 access_token)微信公衆平臺

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

注意說明:因爲微信如今不讓開發者直接在前端使用 https://api.weixin.qq.com 接口獲取數據,因此下面的操做都必須由服務器後臺來完成。

官方的POST參數:


{
  "touser": "OPENID",  
  "template_id": "TEMPLATE_ID", 
  "page": "index",          
  "form_id": "FORMID",         
  "data": {
      "keyword1": {
          "value": "339208499", 
          "color": "#173177"
      }, 
      "keyword2": {
          "value": "2015年01月05日 12:30", 
          "color": "#173177"
      }, 
      "keyword3": {
          "value": "粵海喜來登酒店", 
          "color": "#173177"
      } , 
      "keyword4": {
          "value": "廣州市天河區天河路208號", 
          "color": "#173177"
      } 
  },
  "emphasis_keyword": "keyword1.DATA" 
}

 

 
            var l = "https://api.weixin.qq.com/cgi-bin/message/wxopen/template/send?access_token=" + access_token;
            var tempData = new
            {
                touser = openid,
                template_id = "VErasH9Plzmyw9-PQjiggkBCa3hOU30qfvTaxD******",//這個是一、申請的模板消息id,
                page ="pages/index/index",
                form_id = formId,
                data = new
                {
                    keyword1 = new
                    {
                        value = title,
                        color = "#666666"
                    },
                    keyword2 = new
                    {
                        value = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"),
                        color = "#9b9b9b"
                    },
                    keyword3 = new
                    {
                        value = Remarks,
                        color = "#9b9b9b"
                    }
                },
                color = "#666666"
            };


            X.Component.Tools.WebClient wc = new X.Component.Tools.WebClient();
       
            var result = tempData.ToJson(); //Newtonsoft.Json.JsonConvert.SerializeObject(tempData);
       
            wc.Encoding = System.Text.Encoding.UTF8;
            var obj = wc.Post(l, result); //獲得返回的結果
 

注意 page路徑spa

最後返回的結果:

 

{
    "data": {
        "success": true
    }, 
    "statusCode": 200, 
    "header": {
        "Server": "Microsoft-IIS/7.5", 
        "Access-Control-Allow-Origin": "https://pubchem.ncbi.nlm.nih.gov", 
        "Cache-Control": "private", 
        "X-UA-Compatible": "chrome=1", 
        "Date": "Thu, 28 Sep 2017 04:46:34 GMT", 
        "X-AspNetMvc-Version": "4.0", 
        "Content-Type": "application/json; charset=utf-8", 
        "X-Powered-By": "ASP.NET", 
        "X-AspNet-Version": "4.0.30319", 
        "Content-Length": "16"
    }, 
    "errMsg": "request:ok"
}
