• WebService SOAP1.1 SOAP1.12 HTTP PSOT方式调用

    Visual Studio 2022 新建WebService项目

    创建之后启动运行

    设置默认文档即可

    经过上面的创建WebService已经创建完成，添加HelloWorld3方法，

    [WebMethod]
    public string HelloWorld3(int a, string b)
    {
    //var s = a + b;
    return $"Hello World a+b={a + b}";
    }

    属性页面如下：

     地址加上?wsdl----http://localhost:8012/WebService1.asmx?wsdl 可以查看具体方法，我们点开一个方法，查看具体调用方式，

    http://localhost:8012/WebService1.asmx?op=HelloWorld3

    下面使用 SOAP1.1 SOAP1.12 HTTP PSOT方式调用WebService，代码如下

    271.             //    System.Xml.Serialization.XmlSerializer xmlSerializer= new System.Xml.Serialization.XmlSerializer()
    272.             //}
    273.             #endregion
    274.         }
    275.         #endregion

    使用代码

    1.                 string aa = WebServiceSOAP11(4, "888");
    2.                 Console.WriteLine($"WebService--SOAP1.1-- 返回值：{aa}");
    3.                 aa = WebServiceSOAP11(6, "0000");
    4.                 Console.WriteLine($"WebService--SOAP1.2-- 返回值：{aa}");
    5.                 aa = WebServiceHTTP("a=666666&b=8888");//注意参数名称不一致会报错，a，b
    6.                 Console.WriteLine($"WebService--http-- 返回值：{aa}");

    运行效果
