使用VS2019创建WebService [英] Using VS2019 to create a WebService

问题描述

我想使用Visual Studio 2019在现有的.NET项目中使用C#创建一个WebService.搜索互联网，我所能找到的只是VS较旧版本的教程...

I want to use Visual Studio 2019 to create a WebService inside an existing .NET project, using C#. Searching the internet, all I could find were tutorials for older VS versions...

如何创建它?使用Visual Studio 2019接收POST数据的最佳方法是什么?

How can I create it, and what's the best approach for receiving POST data using Visual Studio 2019?

推荐答案

考虑打开解决方案:

• 右键单击项目名称(在解决方案资源管理器中)，转到添加" ，然后转到添加新项目..."

• Right click on the project name (at the solution explorer), go to "Add" and than "Add new item..."

• 选择"Visual C#" ，向下滚动，选择"Web Service(ASMX)" ，然后单击添加" .

• Select "Visual C#", scroll down, select "Web Service (ASMX)" and click "Add".

在项目的根文件夹上创建了一个名为 WebService.asmx 的文件(或您输入的名称).在内部，您应该看到该代码:

A file called WebService.asmx (Or the name you entered) was create on the root folder of your project. Inside, you should see that code:

<%@ WebService Language="C#" CodeBehind="~/App_Code/WebService.cs" Class="WebService" %>

此文件仅用于在〜/App_Code/WebService.cs" 处调用代码.因此，如果您想通过 POST 进行调用，则应使用

This file is just used to call the code, at "~/App_Code/WebService.cs". So if you want to call it from POST, you should use

www.host.com/pathTo/projectRoot/WebService.asmx/functionName?Params=values

打开〜/App_Code/WebService.cs" 后，您应该会看到类似的内容:

After opening "~/App_Code/WebService.cs", you should see something like that:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;

/// <summary>
/// Summary description for WebService
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. 
// [System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService
{

    public WebService()
    {

        //Uncomment the following line if using designed components 
        //InitializeComponent(); 
    }

    [WebMethod]
    public string HelloWorld()
    {
        return "Hello World";
    }

}

在这里，您可以自定义代码以接收和处理 POST 数据.

Here, you can customize your code to receive and process POST data.

您不能在此处使用Request["param"]，但是HttpContext.Current.Request["param"];是我发现的最佳方法.

You can't use Request["param"] here, but HttpContext.Current.Request["param"]; is the best approach I've found.

就像一个人所说的那样:ASMX是一种古老的实现方式，但是直到今天我们仍然有效.
