WebService进阶

一、C#WebService跨域问题

Web.config中system.web节点下添加

<webServices>
  <protocols>
    <add name="HttpGet"/>
    <add name="HttpPost"/>
    <add name="HttpSoap"/>
    <add name="Documentation"/>
  </protocols>
</webServices>

configuration节点下添加

<system.webServer>
  <httpProtocol>
    <customHeaders>
      <add name="Access-Control-Allow-Methods" value="OPTIONS,POST,GET"/>
      <add name="Access-Control-Allow-Headers" value="x-requested-with,content-type"/>
      <add name="Access-Control-Allow-Origin" value="*"/>
    </customHeaders>
  </httpProtocol>
</system.webServer>

二、ajax请求webservice

html页面:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title></title>
        <script type="text/javascript" src="js/jquery-3.3.1.min.js" ></script>
        <script type="text/javascript">
        $(function(){
              /*无参*/
            $("#btnHelloWorld").click(function(){
                $.ajax({
                    type: "POST",
                    contentType:"application/json",
                    url:"http://localhost:53029/WebService1.asmx/HelloWorld",
                    data:"{}",
                    dataType:'json',
                    success:function(result){                   
                        alert(result.d);
                    }
                });
            });
            /*传入1个参数*/
            $("#btnHello").click(function(){
                $.ajax({
                    type: "POST",
                    contentType:"application/json",
                    url:"http://localhost:53029/WebService1.asmx/Hello",
                    data:"{name:'KiMoGiGi'}",
                    dataType:'json',
                    success:function(result){                   
                        alert(result.d);
                    }
                });
            });
             /*返回泛型列表*/
            $("#btnArray").click(function(){
                $.ajax({
                    type: "POST",
                    contentType:"application/json",
                    url:"http://localhost:53029/WebService1.asmx/CreateArray",
                    data:"{i:10}",
                    dataType:'json',
                    success:function(result){                   
                        alert(result.d.join(" | "));
                    }
                });
            });
             /*返回复杂类型*/
            $("#btnPerson").click(function(){
                $.ajax({
                    type: "POST",
                    contentType:"application/json",
                    url:"http://localhost:53029/WebService1.asmx/GetPerson",
                    data:"{name:'张三',age:26}",
                    dataType:'json',
                    success:function(result){
                        var person = result.d;
                        var showText = [];
                        for(var p in person){
                            showText.push(p + ":" + person[p]);
                        }
                        alert(showText.join("/r/n"));
                    }
                });
            });
         });
    </script>
    </head>
    
    <body>
          <input type="button" id="btnHelloWorld" value="HelloWorld" />
          <input type="button" id="btnHello" value="Hello" />
          <input type="button" id="btnArray" value="CreateArray" />
          <input type="button" id="btnPerson" value="GetPerson" />
    </body>

    [GenerateScriptType(typeof(Person))]        // 不是必要，但推荐添加(如果Person里面再嵌套另一个复杂类型，则必要声明)

    [System.ComponentModel.ToolboxItem(false)]

    // [System.Web.Script.Services.ScriptService]
    public class WebService1 : System.Web.Services.WebService
    {
        /// 无任何参数
        [WebMethod]
        public string HelloWorld()
        {
            return " Hello World ";
        }
        
        /// 传入参数
        [WebMethod]
        public string Hello(string name)
        {
            return string.Format(" Hello {0} ", name);

        {

            while (i >= 0)
            {

            {
                Name = name,
                Age = age
            };
        }

    {
        public string Name { get; set; }
        public int Age { get; set; }

三、webservice的SoapHeader访问验证

1、创建一个实体类AuthorizeHeader 继承【System.Web.Services.Protocols】SoapHeader

    /// <summary>
    /// 头部账号密码验证
    /// </summary>
    public class AuthorizeHeader: SoapHeader
    {
        public string username { get; set; }
        public string password { get; set; }
    }

webservice更改

/// <summary>
/// PubWebService 的摘要说明
/// </summary>
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
// 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消注释以下行。 
[System.Web.Script.Services.ScriptService]
public class PubWebService : System.Web.Services.WebService
{
    public AuthorizeHeader authHeader = null;
    
    [WebMethod(Description = "测试调用验证")]
    [SoapHeader("authHeader")]
    public string HelloWord()
    {
        if (authHeader == null || !ValidateUser(authHeader.username,authHeader.password)) return "无访问权限";
        
        return "Hello Word!";
    }
    
    private bool ValidateUser(string username, string password)
    {
        if (username == "admin" && password == "123456")
            return true;
        return false;
    } 
}

使用posman访问：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Header>
    <AuthorizeHeader xmlns="http://tempuri.org/">
      <username>admin</username>
      <password>123456</password>
    </AuthorizeHeader>
  </soap:Header>
  <soap:Body>
    <GetRegionData xmlns="http://tempuri.org/" />
  </soap:Body>
</soap:Envelope>

调用：

private void button1_Click(object sender, EventArgs e)
{
    string url = "http://localhost:8889/PubWebService.asmx?wsdl";
    PubWebService pubWebService = new PubWebService();
    pubWebService.Url = url;

    AuthorizeHeader authorizeHeader = new AuthorizeHeader();
    authorizeHeader.username = "admin";
    authorizeHeader.password = "123456";

    pubWebService.AuthorizeHeaderValue= authorizeHeader;

    string josnStr=pubWebService.HelloWord();

}

2、使用posman测试 Basic Auth 认证

对应生成了头部信息：

代码分享：

using System.Web;//传递头部参数需要引用

if (HttpContext.Current.Request.Headers.ContainsKey("Authorization"))
{
    var authorize = HttpContext.Current.Request.Headers["Authorization"].ToString();
    if (authorize.Contains("Basic"))//如果是Basic 身份认证
    {
        var info = authorize.Replace("Basic ", string.Empty);
        var bytes = Convert.FromBase64String(info);//反解析Basic 64
        var contents = Encoding.Default.GetString(bytes);
        var dd = contents.Split(":").ToArray();
        var userName = dd[0];//用户名
        var userPwd = dd[1];//密码
        if (userName == "GeBiLaoWang" && userPwd == "123456")
        {
            return "无访问权限";
        }
    }
}

使用窗体调用

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }
    private void button1_Click(object sender, EventArgs e)
    {
        #region 方法一
        string url = "http://localhost:52932/PubWebService.asmx/MethodName";
        string strParams = "";
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        //请求方式POST
        request.Method = "POST";
        //传输数据JSON类型
        request.ContentType = "application/json;charset=utf-8";
        request.Credentials = CredentialCache.DefaultCredentials;//获取应用程序的系统凭据。
        string visitAuthorized = AESHelper.Encrypt("admin:123456");
        request.Headers.Add("VisitAuthorized", visitAuthorized);
        //请求超时时间，10分钟
        request.Timeout = 600000;
        //写入数据
        var data = Encoding.UTF8.GetBytes(strParams);
        request.ContentLength = data.Length;
        Stream writer = request.GetRequestStream();
        writer.Write(data, 0, data.Length);
        writer.Close();
        //请求返回数据
        StreamReader reader = new StreamReader(request.GetResponse().GetResponseStream(), Encoding.UTF8);
        string ret = reader.ReadToEnd();
        reader.Close();
        //解析josn
        ReturnData<List<Sys_Region>> returnData = JsonConvert.DeserializeObject<ReturnData<List<Sys_Region>>>(ret);
        #endregion
    }
}

public class ReturnData<T>
{
    public string code { get; set; }
    public string msg { get; set; }
    public T data { get; set; }
}

public class Sys_Region
{
    public System.Guid region_id { get; set; }
    public Nullable<System.Guid> region_pid { get; set; }
    public string region_name { get; set; }
    public string region_code { get; set; }
    public string region_type { get; set; }
    public Nullable<decimal> region_sort { get; set; }
}
    
}
