ASP.NET C＃中带有http状态代码的Json api输出参数 [英] Json api output parameter with http status code in ASP.NET C#

问题描述

我正在使用asp.net c＃在json中开发web api。我希望http状态代码带有输出参数以响应api的。我可以实现这一点。



我尝试过：

 [WebMethod] 
 [ScriptMethod（ResponseFormat = ResponseFormat.Json）] 
  public   void  GetUserLogin（ string 合同， string  username 
 {
 Authentication obj =  new  Authentication（）; 
 字符串 jSonString =  ; 
 System.Web.Script .Serialization.JavaScriptSerializer serializer = 
  new  System.Web.Script.Serialization.JavaScriptSerializer（）; 
 SqlConnection conn =  new  SqlConn ection（System.Configuration.ConfigurationManager.AppSettings [  conststring]）; 
 SqlCommand command =  new  SqlCommand（）; 
  try  
 {
 DataSet ds =  new  DataSet（）; 
 ds = obj.CheckContract（Contract）; 
 
  if （ds.Tables [ 0 ]！=  null && ds.Tables [ 0 ]。Rows.Count > ;   0 ）
 {
 DataSet dscustomer =  new  DataSet（ ）; 
 dscustomer = obj.CheckCustomer（ds.Tables [ 0 ]。行[ 0 ] [  客户]。ToString（），用户名
 
  if （dscustomer.Tables [ 0 ]！=  null & ;& dscustomer.Tables [ 0 ]。Rows.Count >   0 ）
 {
 
  string  success =   ; 
 success =   {\Customer \：\ + ds.Tables [ 0 ]。行[ 0 ] [  Customer]。ToString（）+   \}; 
  this  .Context.Response.ContentType =   application / json; charset = utf-8; 
  this  .Context.Response.Write（success）; 
 
} 
  else  
 {
  string  success =  ; 
 success =   {\status \：\无效的登录详情。\ }; 
  this  .Context.Response.ContentType =   application / json; charset = utf-8; 
  this  .Context.Response.Write（success）; 
} 
 
} 
  else  
 {
  string  success =  ; 
 success =   {\status \：\无效的登录详情。\ }; 
  this  .Context.Response.ContentType =   application / json; charset = utf-8; 
  this  .Context.Response.Write（success）; 
} 
 
 
} 
 
  catch （例外）
 { 
  string  success =  ; 
 success =   {\status \：\ + er .Message +   \}; 
  this  .Context.Response.ContentType =   application / json; charset = utf-8; 
  this  .Context.Response.Write（success）; 
 
} 
 最后 
 {
 command.Dispose（）; 
  if （conn.State == ConnectionState.Open）
 {
 conn.Close（）; 
 conn.Dispose（）; 
} 
} 
} 

解决方案

我用google搜索asp.net webmethod set status code为你而且这里有一些结果



asp.net - 我可以设置HTTP响应代码&在ASMX JSON服务上抛出异常？ - 堆栈溢出 [ ^ ]



c＃ - Asp.Net web服务：我想返回错误403 forbidden - Stack Overflow [ ^ ]



您可以自己轻松完成此操作，请在提问之前进行基础研究。

I am developing web api's in json using asp.net c#. I want http status code with output parameters in response of api's .how I can I achieve this.

What I have tried:

[WebMethod]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public void GetUserLogin(string Contract, string username
        {
            Authentication obj = new Authentication();
            String jSonString = "";
            System.Web.Script.Serialization.JavaScriptSerializer serializer =
             new System.Web.Script.Serialization.JavaScriptSerializer();
            SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["conststring"]);
            SqlCommand command = new SqlCommand();
            try
            {
                    DataSet ds = new DataSet();
                    ds = obj.CheckContract(Contract);

                    if (ds.Tables[0] != null && ds.Tables[0].Rows.Count > 0)
                    {
                        DataSet dscustomer = new DataSet();
                        dscustomer = obj.CheckCustomer(ds.Tables[0].Rows[0]["Customer"].ToString(), username

                        if (dscustomer.Tables[0] != null && dscustomer.Tables[0].Rows.Count > 0)
                        {
                         
                        string success = "";
                        success = "{\"Customer\": \" " + ds.Tables[0].Rows[0]["Customer"].ToString() + " \"}";
                        this.Context.Response.ContentType = "application/json; charset=utf-8";
                        this.Context.Response.Write(success);
                        
                        }
                        else
                        {
                            string success = "";
                            success = "{\"status\": \"Invalid Login Details.\"}";
                            this.Context.Response.ContentType = "application/json; charset=utf-8";
                            this.Context.Response.Write(success);
                        }

                    }
                    else
                    {
                        string success = "";
                        success = "{\"status\": \"Invalid Login Details.\"}";
                        this.Context.Response.ContentType = "application/json; charset=utf-8";
                        this.Context.Response.Write(success);
                    }
                
               
            }

            catch (Exception er)
            {
                string success = "";
                success = "{\"status\": \"" + er.Message + "\"}";

解决方案

I googled "asp.net webmethod set status code" for you and here are some results

asp.net - Can I Set the HTTP Response Code & Throw an Exception on an ASMX JSON Service? - Stack Overflow[^]

c# - Asp.Net web service: I would like to return error 403 forbidden - Stack Overflow[^]

You could easily have done this yourself, please do basic research before asking a question.
