我正在做一个需要将文件从 iphone 上传到 wcf 服务的项目。我没有 wcf 和 afnetworking 的经验。我已经坚持这一步好几天了，这是我取得的进展：
用于上传文件的 WCF 服务：请注意，我已从Codeproject 网站复制了此代码。
public interface ITransferService
{
[OperationContract]
RemoteFileInfo DownloadFile(DownloadRequest request);
[OperationContract]
void UploadFile(RemoteFileInfo request);
}
public void UploadFile(RemoteFileInfo request)
{
FileStream targetStream = null;
Stream sourceStream = request.FileByteStream;
string uploadFolder = @"C:\upload\";
string filePath = Path.Combine(uploadFolder, request.FileName);
using (targetStream = new FileStream(filePath, FileMode.Create,
FileAccess.Write, FileShare.None))
{
//read from the input stream in 65000 byte chunks
const int bufferLen = 65000;
byte[] buffer = new byte[bufferLen];
int count = 0;
while ((count = sourceStream.Read(buffer, 0, bufferLen)) > 0)
{
// save to output stream
targetStream.Write(buffer, 0, count);
}
targetStream.Close();
sourceStream.Close();
}
}
上传代码在源代码附带的客户端程序上运行良好，我可以通过 wcf 服务上传任何大小和任何类型或文件。
我还发现 AFNetworking 框架在 ios 上非常流行，所以我决定使用它。这是我上传文件的代码：
我已经走了这么远，请在这种情况下帮助我。谢谢你的帮助
好的，这是新的信息：
首先，将文件上传到 wcf 服务的 c# 代码（正在工作）
protected void Button1_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile)
{
System.IO.FileInfo fileInfo =
new System.IO.FileInfo(FileUpload1.PostedFile.FileName);
FileTransferServiceReference.ITransferService clientUpload =
new FileTransferServiceReference.TransferServiceClient();
FileTransferServiceReference.RemoteFileInfo
uploadRequestInfo = new RemoteFileInfo();
using (System.IO.FileStream stream =
new System.IO.FileStream(FileUpload1.PostedFile.FileName,
System.IO.FileMode.Open, System.IO.FileAccess.Read))
{
uploadRequestInfo.FileName = FileUpload1.FileName;
uploadRequestInfo.Length = fileInfo.Length;
uploadRequestInfo.FileByteStream = stream;
clientUpload.UploadFile(uploadRequestInfo);
//clientUpload.UploadFile(stream);
}
}
}
第二：用于将文件上传到服务器的remotefileinfo类：
public class RemoteFileInfo : IDisposable
{
[MessageHeader(MustUnderstand = true)]
public string **FileName**;
[MessageHeader(MustUnderstand = true)]
public long **Length**;
[MessageBodyMember(Order = 1)]
public System.IO.Stream **FileByteStream**;
public void Dispose()
{
if (FileByteStream != null)
{
FileByteStream.Close();
FileByteStream = null;
}
}
}
从所有这些代码中，我了解到我需要创建一个包含“文件名”“文件长度”和文件数据“文件字节流”的请求。我在代码中尝试了一些东西，但是当我尝试使用此代码上传图像时服务器给出错误 415：
AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://192.168.2.121:85"]];
UIImage *image = [UIImage imageNamed:@"test.jpg"];
NSData *data = UIImageJPEGRepresentation(image, 0.2);
NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
[parameters setObject:@"test.jpg" forKey:@"FileName"];
[parameters setObject:[NSString stringWithFormat:@"%i",data.length] forKey:@"Length"];
NSMutableURLRequest *myRequest = [client multipartFormRequestWithMethod:@"POST" path:@"/webservice/Transferservice.svc/UploadFile" parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFileData:data name:@"RemoteFileInfo" fileName:@"test.jpg" mimeType:@"image/jpeg"];
}];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]initWithRequest:myRequest];
[operation
setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"success: %@", operation.responseString);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"error: %@", operation.error);
}
];
[[[NSOperationQueue alloc] init] addOperation:operation];
这里也是服务的 WSDL 链接：
我真的需要这样做，谢谢你的再次帮助......
