使用 WCF 服务将大文件上传到 Windows azure 存储时出错

Question

我有一个示例 Web 应用程序，我通过它使用 WCF 服务，该服务旨在将大容量 [高达 50mb] 文件上传到 azure 存储，我收到错误消息说远程服务器返回了意外响应：(413) 请求实体太大。

这是我的示例 Wcf 服务代码： 接口[IService1.cs]

namespace FileService
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        void UploadFile(Stream inputstream);

    }

}

Service1.svc

public class Service1 : IService1
        {
           public void UploadFile(Stream inputstream)
            {

                CloudStorageAccount storageAccount = CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("StorageConnectionString"));

                // Create the blob client.
                CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

                // Retrieve reference to a previously created container.
                CloudBlobContainer container = blobClient.GetContainerReference("images");

                // Retrieve reference to a blob named "myblob".
                CloudBlockBlob blockBlob = container.GetBlockBlobReference("testfile");

                 blockBlob.UploadFromStream(inputstream);
            }
        }

Test.aspx 页面使用 wcf 服务

protected void Button1_Click(object sender, EventArgs e)
    {
        ServiceReference1.IService1 clientUpload = new ServiceReference1.Service1Client();
        clientUpload.UploadFile(FileUpload1.FileContent);
    }

Answer 1

在您的 web.config 中检查您正在使用的绑定，并在传输部分中添加 maxReceivedMessageSize。

例如，如果您使用的是 httpTransport。

<httpTransport maxReceivedMessageSize="2147483647"/>
