C# 钉钉接口-给用户发钉盘文件消息/钉盘文件上传
钉钉接口 给用户发钉盘文件消息
步骤概括：
- 创建一个用于企业内部开发的H5微应用。将文件发送给指定用户，用户将收到以次应用名义发送的一条文件消息
- 服务端调用“单步上传文件”接口，上传文件获取mediaId
- 服务端调用“发送钉盘文件给指定用户”接口，把钉盘文件当做消息内容发送给用户
这里省略创建微应用的步骤。
步骤1：获取access_token (GET)
请求地址：https://oapi.dingtalk.com/gettoken?appkey=key&appsecret=secret
返回说明
{ "errcode": 0, "errmsg": "ok", "access_token": "fw8ef8we8f76e6f7s8df8s" }
步骤2：调用“单步上传文件”接口，上传文件获取mediaId (POST)
文件大小 取字节；
返回说明
{ "media_id": "xxxxxxxx", "errcode":0, "errmsg":"ok" }
步骤3：发送钉盘文件给指定用户(POST)
media_id 和file_name需要转成urlEncode格式，{"errcode":40007,"errmsg":"不合法的媒体文件id"}除了media_id 不存在、为空，还有一个原因是因为没有转格式
引用 System.Web.HttpUtility;
HttpUtility.UrlEncode(" 内容 ");
返回结果
{ "errcode":0, "errmsg":"ok" }
