我正在尝试发布API以将数据发送到API，该API调用我的内部API服务将数据发送给其他API I服务。实体包含带有文件的属性。这只将文件发送给另一个派生，但NameSender属性不随文件一起发送。
public class Email
{
public string NameSender{ get; set; }
public List<IFormFile> Files { get; set; }
}
[Consumes("multipart/form-data")]
[HttpPost]
public IActionResult SendEmail([FromForm]Entity entity)
{
try
{
string Servicesfuri = this.serviceContext.CodePackageActivationContext.ApplicationName + "/" + this.configSettings.SendNotificationServiceName;
string proxyUrl = $"http://localhost:{this.configSettings.ReverseProxyPort}/{Servicesfuri.Replace("fabric:/", "")}/api/values/Send";
//attachments
var requestContent = new MultipartFormDataContent();
foreach (var item in entity.Files)
{
StreamContent streamContent = new StreamContent(item.OpenReadStream());
var fileContent = new ByteArrayContent(streamContent.ReadAsByteArrayAsync().Result);
requestContent.Add(fileContent, item.Name, item.FileName);
}
HttpResponseMessage response = this.httpClient.PostAsync(proxyUrl, requestContent).Result;
if (response.StatusCode != System.Net.HttpStatusCode.OK)
{
return this.StatusCode((int)response.StatusCode);
}
return this.Ok(response.Content.ReadAsStringAsync().Result);
}
catch (Exception e)
{
throw e;
}
}
这个方法对我有效。你可以使用表单数据和文件
public async Task<bool> Upload(FileUploadRequest model)
{
var httpClientHandler = new HttpClientHandler()
{
Proxy = new WebProxy("proxyAddress", "proxyPort")
{
Credentials = CredentialCache.DefaultCredentials
},
PreAuthenticate = true,
UseDefaultCredentials = true
};
var fileContent = new StreamContent(model.File.OpenReadStream())
{
Headers =
{
ContentLength = model.File.Length,
ContentType = new MediaTypeHeaderValue(model.File.ContentType)
}
};
var formDataContent = new MultipartFormDataContent();
formDataContent.Add(fileContent, "File", model.File.FileName); // file
formDataContent.Add(new StringContent("Test Full Name"), "FullName"); // form input
using (var client = new HttpClient(handler: httpClientHandler, disposeHandler: true))
{
client.DefaultRequestHeaders.Add("Authorization", "Bearer " + tokenString);
using (var res = await client.PostAsync("http://filestorageurl", formDataContent))
{
return res.IsSuccessStatusCode;
}
}
}
