发送多个参数XMLHttpRequest和WCF

var xhr = new XMLHttpRequest();

xhr.open('POST', 'http://example.com/api', true);

xhr.setRequestHeader('Content-Type', 'application/json');

var params = {
  param1: 'value1',
  param2: 'value2',
  param3: 'value3'
};

var jsonParams = JSON.stringify(params);

xhr.send(jsonParams);

[ServiceContract]
public interface IMyService
{
    [OperationContract]
    void MyMethod(string param1, int param2, bool param3);
}

public class MyService : IMyService
{
    public void MyMethod(string param1, int param2, bool param3)
    {
        // 处理参数
    }
}
