WebApi调用通用方法

Posted 2020-12-24

WebApi传递基础参数的时候可能会有各种各样的问题，有的需要在服务端增加[FromBody]的特性，有的需要增加一层封装为实体，有的用动态类型，下面介绍一个方便的调用方法。通过WebClient类。代码如下，需要什么参数只需要在QueryString中添加即可。

 try
                {
                    WebClient client = new WebClient();
                    //client.QueryString.Add("account", "冯宝宝");
                    //client.QueryString.Add("password", "7777");
                    client.QueryString.Add("name", "冯宝宝");
                    client.Encoding = Encoding.UTF8;

                    client.Headers.Add(HttpRequestHeader.ContentType, "application/json");
                    //string result = client.UploadString("http://localhost:51151/Api/Users/Login", "");
                    string result = client.UploadString("http://localhost:51151/Api/Users/WithStringParamNoFromBody", "");
                }
                catch (Exception ex)
                {

                }

后端WebApi代码如下：

 [AllowAnonymous]
        [HttpPost]
        public IEnumerable<Users> WithStringParamNoFromBody(string name)
        {
            return _userList;
        }

                 [AllowAnonymous]
        [HttpPost]
        public string Login(string account, string password)
        {
            if (account.Equals("冯宝宝") && password.Equals("7777"))
            {
                FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(0,
                    account,
                    DateTime.Now,
                    DateTime.Now.AddMinutes(5),
                    true,
                    $"{account}&{password}",
                    FormsAuthentication.FormsCookiePath);
                var result = new { Result = true, Ticket = FormsAuthentication.Encrypt(ticket) };
                return JsonConvert.SerializeObject(result);
            }
            else
            {
                var result = new { Result = false };
                return JsonConvert.SerializeObject(result);
            }
        }
