【问题描述】:
我有 WCF Rest 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();
}
我想将文件(嗯,文件;一次一个)上传到。使用此表格进行测试:
<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 enctype,我什么也得不到;该服务永远不会受到影响。我在代码中放了一个中断以查看发生了什么,但从未达到。我是否需要在“multipart/form-data”编码类型的 URITemplate 属性中做一些特别的事情?我还缺少什么?最糟糕的是,我使用 Fiddler 来查看每个选项发送到服务的内容,并没有什么险恶的外观。
没有'multipart/form-data':
