本文介绍了我们如何将类对象作为XML传递给WCF REST后的METHOD?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个场景,我需要将类对象作为输入发送到WCF REST方法,如下所示。
I have a scenario where I need to send the class object to the WCF REST method as input as given below.
[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "/InsertContact", ResponseFormat = WebMessageFormat.Xml,
RequestFormat = WebMessageFormat.Xml, BodyStyle = WebMessageBodyStyle.Wrapped)]
int InsertContact(ContactType objContactType);

I想让我的REST API接受JSON或XML请求dep结束于client.Do我需要在WebInvoke属性或web.config中设置此属性吗?
任何人都可以帮我这个吗?
I want to make my REST API to accept either JSON or XML request depending on the client.Do I need to set this property in the WebInvoke attribute or in the web.config ?
Can anyone help me regarding this ?
推荐答案
我通常使用DataContractSerializer序列化对象以获取实际的xml。
其次我使用BodyStyle = WebMessageBodyStyle.Bare
public static string Serialize(ContactType obj)
{
using(MemoryStream memoryStream = new MemoryStream())
{
使用(StreamReader reader = new StreamReader(memoryStream))
{
DataContractSerializer serializer = new DataContractSerializer(obj.GetType()) ;
serializer.WriteObject(memoryStream,obj);
memoryStream.Position = 0;
return reader.ReadToEnd();
} < br $>
}
}
public static ContactType反序列化(字符串xml)
{
使用(Stream stream = new MemoryStream())
{
byte [] data = System.Text.Encoding.UTF8.GetBytes( xml);
stream.Write(data,0,data.Length);
stream.Position = 0;
DataContractSerializer deserializer = new DataContractSerializer(typeof(ContactType));
return(ContactType)deserializer.ReadObject(stream);
}
}
i normally serialize the object with DataContractSerializer to get the actual xml.
secondly i use BodyStyle = WebMessageBodyStyle.Bare
public static string Serialize(ContactType obj)
{
using (MemoryStream memoryStream = new MemoryStream())
{
using (StreamReader reader = new StreamReader(memoryStream))
{
DataContractSerializer serializer = new DataContractSerializer(obj.GetType());
serializer.WriteObject(memoryStream, obj);
memoryStream.Position = 0;
return reader.ReadToEnd();
}
}
}
public static ContactType Deserialize(string xml)
{
using (Stream stream = new MemoryStream())
{
byte[] data = System.Text.Encoding.UTF8.GetBytes(xml);
stream.Write(data, 0, data.Length);
stream.Position = 0;
DataContractSerializer deserializer = new DataContractSerializer(typeof(ContactType));
return (ContactType)deserializer.ReadObject(stream);
}
}
