百度api短信开发

公司原来有一个短信发送的功能，是调用第三方的，但是很不稳定，时不时就收不到短信，但是钱已经扣了。对于这样的事，谁都忍受不了的。于是想找一个稳定短信发送平台，第一想到的是阿里云，百度。在这两个平台上公司都有认证了，于是省了很多事。现在开始吧。

找到百度开放云登录窗口，然后登录，进入控制中心，然后在产品服务中找到，如下图

简单消息服务SMS。前提是账号已经认证了。

点击它跳转到

首先是短信签名申请，这个可以根据他们提供的文档一一操作，盖章，拍照上传，等待他们审核（大概两个星期吧）。审核成功，然后是短信模版申请，然后审核（大概一两天）

数量没有限制。

这个时候其实我们可以根据他们文档进行开发了，只要签名和短信模板审核已通过我们就可以测试了。

他们有Java等，

SDK，但是没有.net的,因此我只能调用他们的API实现。首先要认证。

这个我是偷了一回懒。由于有同事做好了这个，他之前实现了一个百度api发送邮箱的功能。我只要把他那部分认证的代码搬过来就是了。如果愿意看，也是可以实现的。我把认证的代码搬来。

这个方法实现。

代码测试，发送的内容是自己根据自定义的模板来的，组成标准的格式就可以了。

 Dim SMSinfo As SMSInfo = New SMSInfo()

   SMSinfo.TemplateId = "申请的短信模板"

   SMSinfo.Receiver = "[""手机号码""]"

   SMSinfo.ContentVar = "{\""短信内容参数一\"":\""zhangsan \"",\""短信内容参数二\"":\""888888 \"",\""短信内容参数三\"":\""我是测试内容，我是测试内容 \""}"

  Protected Sub btntest_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btntest.Click

     Dim bdsms As BaiduSMSTest = New BaiduSMSTest(SMSinfo)

     Dim result As String = bdsms.SendSMSWEBAPI()

 End Sub

其实也可以在百度平台上测试

这样就算完成整个短信开发了。

下面这个是C#版本的

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

namespace PictureTest.BaiduSMS

{

    public class SMSInfo

    {

        //模板

        public string TemplateId { get; set; }

        //接受者

        public string Receiver { get; set; }

        //内容

        public string ContentVar { get; set; }

    }

}
