使用参数调用 Web 服务

Question

我必须调用一个Web服务。 Web 服务具有输入两个参数，并且不会在输出中返回任何内容。

你能告诉我代码(写在下面(是否正确和完整吗？ 我把它插入主电源内。

var httpWebRequest = (HttpWebRequest)WebRequest.Create("url");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
httpWebRequest.Credentials = new NetworkCredential("user", "pwd", "domain");
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{p1:'Hello'";
string tmpjs = ",p2:'world'}";                       
json = json + tmpjs;
streamWriter.Write(json);
streamWriter.Flush();
streamWriter.Close();
}
HttpWebResponse httpResponse = (HttpWebResponse) httpWebRequest.GetResponse();

添加服务引用和调用 Web 服务方法会更容易。

然后，您可以像这样访问该服务。

您的代码如下所示：

string json = "{p1:'Hello'";                              
string tmpjs = ",p2:'world'}";   
json = json + tmpjs;
using(YourService service = new YourService()) 
{
service.Credentials = new NetworkCredential("user", "pwd", "domain");
serivce.YourServiceMethod(json, param2);
}
