我读了一些关于这个的文章,我发现要获得wcf从我们添加的帖子请求中获取数据
[ServiceContract]
public interface IService1 {
[OperationContract]
[WebInvoke(
Method = "POST",BodyStyle = WebMessageBodyStyle.Bare,UriTemplate = "/GetData")]
void GetData(Stream data);
}
并在实施中
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();
}
我的问题是我应该怎样做,在表单请求中提交操作会发送到我的服务并消费？
在Stream参数中,我是否可以通过Request [“FirstName”]从表单中获取信息？
解决方法
您的代码未正确解码请求正文 – 您正在创建一个字符串值数组,每个字符串值都包含一个字符.获取请求体后,您需要解析查询字符串(使用HttpUtility是一种简单的方法).下面的代码显示了如何正确获取正文和其中一个字段.
public class StackOverflow_7228102
{
[ServiceContract]
public interface ITest
{
[OperationContract]
[WebInvoke(
Method = "POST",UriTemplate = "/GetData")]
string GetData(Stream data);
}
public class Service : ITest
{
public string GetData(Stream input)
{
string body = new StreamReader(input).ReadToEnd();
NameValueCollection nvc = HttpUtility.ParseQueryString(body);
return nvc["FirstName"];
}
}
public static void Test()
{
string baseAddress = "http://" + Environment.MachineName + ":8000/Service";
WebServiceHost host = new WebServiceHost(typeof(Service),new Uri(baseAddress));
host.Open();
Console.WriteLine("Host opened");
WebClient c = new WebClient();
c.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
Console.WriteLine(c.UploadString(baseAddress + "/GetData","FirstName=John&LastName=Doe&Age=33"));
Console.Write("Press ENTER to close the host");
Console.ReadLine();
host.Close();
}
}
