Question

我有一个WCF休息服务：

      [WebHelp(Comment = "Sample description for GetData")]
    [WebInvoke(Method="POST", UriTemplate = "invoke", BodyStyle =WebMessageBodyStyle.Bare)]
    [OperationContract]
    public string GetData( Stream input)
    {
        long incomingLength = WebOperationContext.Current.IncomingRequest.ContentLength;
        string[] result = new string[incomingLength];
        int cnter = 0;
        int arrayVal = -1;
        do
        {
            if (arrayVal != -1) result[cnter++] = Convert.ToChar(arrayVal).ToString();

            arrayVal = input.ReadByte();
        } while (arrayVal != -1);

        return incomingLength.ToString();
    }

我想上传文件（好吧，文件;一次一个）。使用此表单进行测试：

    <form method="post" action="Service.svc/invoke" >
        <input type="file" name="aFile" />
    </form>
    <input type="button" onclick="document.forms[0].submit();" />

我可以看到服务接收数据，即使表单的enctype设置为'multipart / form-data'，也只接收元素名称和上传文件的名称。但是，如果我设置了enctype，我什么也得不到;该服务永远不会被击中。我在代码中休息一下，看看发生了什么，但从未达成过。我是否需要在'multipart / form-data'enctype的URITemplate属性中做一些特殊操作？我还缺少什么？对于它，我使用Fiddler来查看每个选项发送给服务的内容，并且没有任何险恶的外观。

没有'multipart / form-data'：

Accept: application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwave-flash, */*

使用：

Accept: application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwave-flash, */*

我没有想法

Answer 1

你看到这个问题了吗？ WCF service to accept a post encoded multipart/form-data

Answer 2

必须在web.config中进行更改...

system.serviceModel > bindings > webHttpBinding > binding > transferMode="Streamed"

Answer 3

我使用上面的代码没有成功。我的网络服务没有被调用。我还根据"WCF Service to accept a post-encoded multipart form data"修改了web.config。

我所有其他服务方法都运行正常。
