Question

我已经编写了一个ajax函数和WCF类，用于将文件上传到服务器中的文件夹，但是不幸的是，图像已上传到该文件夹，但无法打开。当我尝试打开它们时，出现错误，提示其损坏，当我上传.doc，pdf或.excel文件时也会发生同样的事情。

但仅适用于.txt文件。

这是我的WCF接口类

[ServiceContract]
    public interface IFileUpload
    {
        [OperationContract]
        [WebInvoke(Method = "POST", UriTemplate = "Upload/{fileName}")]
        String UploadFile(String fileName, Stream data);

课程的实现

  public class FileUpload : IFileUpload
    {
        public String UploadFile(String fileName, Stream streamData)
        {

            String fileId = fileName;
            Logger.Info("file Name" + fileName);
            string FilePath = Path.Combine(HostingEnvironment.MapPath("~/Uploads"), fileName);
            Logger.Info("file path" + FilePath);


            int length = 0;
            using (FileStream writer = new FileStream(FilePath, 
 FileMode.Create))
            {
                int readCount;
                var buffer = new byte[8192];
                while ((readCount = streamData.Read(buffer, 0, buffer.Length)) != 0)
                {
                    writer.Write(buffer, 0, readCount);

                    length += readCount;
                }
                streamData.Close();
            }

            return "fileId";
        }

用于从UI提交文件的Ajax函数

$.ajax({
                    url: fileUpload + $scope.filename,
                    method: "POST",
                    cache: false,
                    data: data,
                    contentType: "application/octet-stream",
                    enctype: 'multipart/form-data',
                    processData: false

                }).success(function (response) {
                    document.getElementById('file2').value = "";

                    console.log("File uploaded successfully");

                }).error(function (xhr, rrr, error) {
                    console.log("Error while uploading the file: - " + error);
                })

Web.config脚本绑定配置

<bindings>
        <webHttpBinding>
            <binding name="webBinding" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
                <security mode="None">
                    <transport clientCredentialType="None" />
                </security>
            </binding>
            <binding name="FileWorker.webHttpBinding" maxBufferSize="2147483647" 
                maxReceivedMessageSize="2147483647" transferMode="Streamed">
                <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
                    maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
            </binding>
            <binding name="webBindingHTTPS" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
                <security mode="Transport">
                    <transport clientCredentialType="None" />
                </security>
            </binding>
        </webHttpBinding>
    <bindings>

我到处都进行了研究，但似乎没有任何作用
