WEB SERVICE 接口：

C# Http Post 调用：

public void PostText()
{
string url = "http://localhost:80/WebService.asmx";
string method = "MaterialRequest";

string jsondata = "[{\"WorkNo\": \"100001\", \"PN\": \"300003398\", \"PN_Name\": \"电容器，呃呃按时\",\"Unit\": \"只\",\"Qty\": \"5000\",\"Need_time\": \"2020 - 1 - 20\"},{\"WorkNo\": \"100001\", \"PN\": \"300003397\", \"PN_Name\": \"电容器，呃呃按时\",\"Unit\": \"只\",\"Qty\": \"5000\",\"Need_time\": \"2020 - 1 - 20\"}]";

string result = HttpPostWebService(url, method, jsondata);

Console.WriteLine(result);

}

public string HttpPostWebService(string url, string method,string jsondata)
{

string result = string.Empty;
string param = string.Empty;
byte[] bytes = null;

Stream writer = null;
HttpWebRequest request = null;
HttpWebResponse response = null;

param = HttpUtility.UrlEncode("jsonText") + "=" + HttpUtility.UrlEncode(jsondata);
bytes = Encoding.UTF8.GetBytes(param);

request = (HttpWebRequest)WebRequest.Create(url + "/" + method);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = bytes.Length;

try
{
writer = request.GetRequestStream(); //获取用于写入请求数据的Stream对象
}
catch (Exception ex)
{
return "-1";
}

writer.Write(bytes, 0, bytes.Length); //把参数数据写入请求数据流
writer.Close();

try
{
response = (HttpWebResponse)request.GetResponse(); //获得响应
}
catch (WebException ex)
{
return "-1";
}

// web service 返回的是XML ，所有需要这么读取

#region 这种方式读取到的是一个返回的结果字符串
Stream stream = response.GetResponseStream(); //获取响应流        
XmlTextReader Reader = new XmlTextReader(stream);
Reader.MoveToContent();
result = Reader.ReadInnerXml();
#endregion

 

// 控制器方法返回的是字符串，不管是不是XML，不能用上面的方法读取，而只能用这个方法读取返回的字符。

#region 这种方式读取到的是一个Xml格式的字符串    
//StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
//result = reader.ReadToEnd();
#endregion

response.Dispose();
response.Close();

Reader.Dispose();
Reader.Close();

stream.Dispose();
stream.Close();

return result;
}

注意：下一行是否注释都能正常执行

 

下面是C#环境的测试界面：

 

如果按照上面的URL：http://localhost:6311/WebService.asmx?op=MaterialRequest 执行错误。

URL必须用： http://localhost:80/WebService.asmx/MaterialRequest
