cURL发布到HTTPCLient C#

Question

我想将File发布到PushBullet API服务

在API的信息站点中显示了一个示例

curl -i https://api.pushbullet.com/api/pushes \
-u API_KEY:
-F device_iden=u1qSJddxeKwOGuGW
-F type=file
-F file=@test.txt

而我正试图用C#中的HttpClient来做

我知道如何使用Httpclient发布文件,使用MultipartFormDataContent,但是如何将device_iden和类型信息添加到客户端？

我正在使用它

using (var content = new MultipartFormDataContent())
            {
                try
                {
                    content.Add(new StreamContent(new FileStream(pathFile, FileMode.Open, FileAccess.Read)));
                    var resp = wc.PostAsync(new Uri(baseUri, "api/pushes"), content);

                }
                catch (Exception)
                {

                    throw;
                }
            }

使用CURL和fiddler这将是POST

在尝试使用fiddler后,最终可以发布帖子:

第一:

public static void PushFile(string pathFile, string iddev)
        {         
            string name = Path.GetFileName(pathFile);
            using (var wc = GetClient())
            {
                using (var multiPartCont = new MultipartFormDataContent())
                {
                    multiPartCont.Add(addStringContent("device_iden", iddev));
                    multiPartCont.Add(addStringContent("type","file"));
                    multiPartCont.Add(addStreamContent(new FileStream(pathFile,FileMode.Open),name ));

                    try
                    {
                        var resp = wc.PostAsync(new Uri(baseUri, "api/pushes"), multiPartCont);
                        Task<string> result = resp.Result.Content.ReadAsStringAsync();
                        //string resultado = result.Result;
                    }
                    catch (Exception)
                    {
                        throw;
                    }
                }
            }            
        }

然后创建字符串内容和流内容的方法

private static StreamContent addStreamContent(Stream stream, string filename )
    {
        var fileContent = new StreamContent(stream);
        fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
        {
            Name = "\"file\"",
            FileName = "\""+filename+"\""
        };
        fileContent.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
        return fileContent;
    }
private static StringContent addStringContent(string name, string content)
{
    var fileContent = new StringContent(content);
    fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
    {
        Name = "\"" + name + "\""
    };
    return fileContent;
}
