Xamarin.Forms 使用HttpClient上传文件
在应用开发中,上传图片很多时候都是不可避免的问题;
以下用HttpClient实现的上传文件代码:
1 public static async Task<string> UploadFileAsync(string url ,string path) 2 { 3 using (var client = new HttpClient()) 4 { 5 using (var content = new MultipartFormDataContent("Upload----" + DateTime.Now.Ticks.ToString("x"))) 6 { 7 var upfilebytes = File.ReadAllBytes(path); 8 var ms = new MemoryStream(upfilebytes); 9 content.Add(new StreamContent(ms), "file", "upload.jpg"); 10 using (var httpResponseMessage = await client.PostAsync(url, content)) 11 { 12 var responseContent = ""; 13 if (httpResponseMessage.IsSuccessStatusCode) 14 { 15 responseContent = await httpResponseMessage.Content.ReadAsStringAsync(); 16 } 17 return responseContent; 18 } 19 } 20 } 21 }
