Mailgun使用RestSharp发送附件-Java 学习之路

我正在使用RestSharp尝试使用Mailgun API发送附件 . 我尝试使用硬编码路径从系统中的文件附加，也使用 varbinary(MAX) （SQL Server）属性上的 ToArray() 方法从数据库中存储的二进制文件附加，但都没有成功 .

附件在技术上发送，但当电子邮件到达我的收件箱时，文件大小总是大约302字节，并且总是损坏 . 我尝试了3个不同的文件，每次都遇到同样的问题 .

电子邮件的其余部分发送，传递和显示正常 . 这只是被打破的附件 .

代码细分：

// Doesnt work(Data property is varbinary(MAX)
request.AddFileBytes("attachment",databaseModel.Data.ToArray(),databaseModel.Filename, "multipart/form-data");

// Also doesnt work(Data property is varbinary(MAX)
request.AddFile("attachment",databaseModel.Data.ToArray(),databaseModel.Filename, "multipart/form-data");

// Also doesnt work        
var path = @"D:\Template.pdf";
request.AddFile("attachment",path,"multipart/form-data");

我想到了..

不应该在request.AddFile（）上添加“multipart / form-data”;

删除此功能可以解决问题 .

此代码有效：

public static void Main(string[] args)
{
    Console.WriteLine(SendSimpleMessage().Content.ToString());
    Console.ReadLine();
}

public static IRestResponse SendSimpleMessage()
{
    var path1 = @"C:\Users\User\Pictures\website preview";
    var fileName = "Learn.png";
    RestClient client = new RestClient();
    client.BaseUrl = new Uri("https://api.mailgun.net/v3");
    client.Authenticator =
        new HttpBasicAuthenticator("api",
                                    "key-934345306fead7de0296ec2fb96a143");
    RestRequest request = new RestRequest();
    request.AddParameter("domain", "mydomain.info", ParameterType.UrlSegment);
    request.Resource = "{domain}/messages";
    request.AddParameter("from", "Excited User <example@mydomain.info>");
    request.AddParameter("to", "peter.cech@gmail.com");        
    request.AddParameter("subject", "Hello");
    request.AddParameter("text", "Testing some Mailgun awesomness! This is all about the text only. Just testing the text of this email.";
    request.AddFile("attachment", Path.Combine(path1,fileName));
    request.Method = Method.POST;
    return client.Execute(request);
}
