今儿查了好多关于webapi接收前台同时传来的参数和文件，这一通查找啊，把谷歌百度都翻烂了，找了一堆乱七八糟的，和大家分享下。
好多人们是这样做的
public async Task<HttpResponseMessage> PostFormData(){// Check if the request contains multipart/form-data. // 检查该请求是否含有multipart/form-data if (!Request.Content.IsMimeMultipartContent()){throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);}string root = HttpContext.Current.Server.MapPath("~/App_Data");var provider = new MultipartFormDataStreamProvider(root);try{// Read the form data. // 读取表单数据 await Request.Content.ReadAsMultipartAsync(provider);// 显示所有“键-值”对 foreach (var key in provider.FormData.AllKeys){foreach (var val in provider.FormData.GetValues(key)){//Trace.WriteLine(string.Format("{0}: {1}", key, val));}}// This illustrates how to get the file names. // 以下描述如何获取文件名 foreach (MultipartFileData file in provider.FileData){Trace.WriteLine(file.Headers.ContentDisposition.FileName);Trace.WriteLine("Server file path: " + file.LocalFileName);}return Request.CreateResponse(HttpStatusCode.OK);}catch (System.Exception e){return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, e);}}
这让我一通看才看明白，而且上面还是整理完他们代码过后的
后来自己找到了比较好的方法，如下
public IHttpActionResult getTest2(){string id=HttpContext.Current.Request["id"];string name = HttpContext.Current.Request["name"];HttpFileCollection files = HttpContext.Current.Request.Files;foreach (string key in files.AllKeys){HttpPostedFile file = files[key];//file.ContentLength文件长度if (string.IsNullOrEmpty(file.FileName) == false)file.SaveAs(HttpContext.Current.Server.MapPath("~/App_Data/") + file.FileName);}return Ok("success2");}
简单明了，共享之，希望对大家有帮助。
