The C # calling interface receives the result "get,post generic"

1. First, the client invokes an instance of the interface

1.1 Define the Receive interface result class first

 Public class resultmsg    {        publicboolgetset;}          Public string Get Set ; }          Public string Get Set ; }    }

1.2 User Login As an example, the login request interface input parameters user name password to determine whether the correct

 Public StaticResultmsg Checklogin (stringAccountstringpwd) {           //Tools.Common1.WriteLog ("Checklogin", "Checklogin", "Account:" + account + "----pwd:" + pwd);Webapiresult msg = WEBAPIHELPER.GETWEBAPI (New{UserName = account, PassWord = pwd},"/useraccounts/login/"); if(Msg. Success) {returnMsg.result; }            Else            {                return NewResultmsg () {title =false, message ="the request interface failed,"+Msg.result.message}; }        }

Call the interface, add the access account password in the header to improve the security of the interface

Private Const stringPWD ="abc_2015?"; Private Const stringAccount ="Webaccount"; #regionRequest Webapi/// <summary>       ///Request Webapi/// </summary>       /// <param name= "model" ></param>       /// <param name= "page" ></param>       /// <returns></returns>        Public StaticWebapiresult Getwebapi (ObjectModelstringpath) {WebClient WC=NewWebClient (); Wc. Headers.add (Httprequestheader.accept,"Application/json"); Wc. Headers.add (Httprequestheader.contenttype,"Application/json; Charset=utf-8"); stringAuth =authorizationhelper.getauthorization1 (account, path, PWD); Wc.           Headers.add (Httprequestheader.authorization,auth); byte[] PostData = System.Text.Encoding.UTF8.GetBytes (NewJavaScriptSerializer ().           Serialize (model)); Try           {               byte[] Text = WC. Uploaddata (domain + path,"Post", PostData); stringstr =System.Text.Encoding.UTF8.GetString (Text); return NewJavaScriptSerializer (). Deserialize<webapiresult>(str); }           Catch(Exception ex) {return NewWebapiresult () {Success =false, result =NewResultmsg () {title =false, message =Ex.           Message}}; }       }       #endregion    }

1.3 Interfaces in another project, the example is as follows:

Under the App_start folder of the interface project, create a new class Loginattribute to determine if the account password transferred in the header is correct

    //indicates that the attribute can be used for classes, methods, and attributes cannot be repeatedly placed in front of the same program entity multiple times[AttributeUsage (AttributeTargets.Class | AttributeTargets.Method, AllowMultiple =false)]     Public classLoginattribute:actionfilterattribute {/// <summary>        ///before action is executed/// </summary>        /// <param name= "Filtercontext" ></param>         Public Override voidonactionexecuting (ActionExecutingContext filtercontext) {//The filter context is empty and throws an exception            if(Filtercontext = =NULL)            {                Throw NewArgumentException ("Filtercontext"); }            //get access Path, account number, timestamp, redaction            varPath =filterContext.HttpContext.Request.Path.ToString (); varauthorization = filtercontext.httpcontext.request.headers["Authorization"]; if(!string. IsNullOrEmpty (Authorization)) {//Split validation string, Account,mac,salt                string[] STRs = authorization. Split (','); if(STRs. Length = =3)                {                    stringaccount = strs[0]. Replace ("account=",""); varMac = strs[1]. Replace ("mac=",""); varSalt = strs[2]. Replace ("salt=",""); if(!string. IsNullOrEmpty (account)) {Try                        {                            varPWD =System.configuration.configurationmanager.appsettings[account].                            ToString (); stringciphertext =uri.escapedatastring (PISCenter.Common.Utility.GetCiphertext (account, path, salt, pwd)); if(ciphertext. Equals (Mac)) {Base.                            OnActionExecuting (Filtercontext); }                        }                        Catch{Filtercontext.result=NewJsonresult {Data =New{title =false, message ="authentication error, Access denied"}, Jsonrequestbehavior =Jsonrequestbehavior.allowget}; }                    }                    Else{Filtercontext.result=NewJsonresult {Data =New{title =false, message ="authentication error, Access denied"}, Jsonrequestbehavior =Jsonrequestbehavior.allowget}; }                }                Else{Filtercontext.result=NewJsonresult {Data =New{title =false, message ="authentication error, Access denied"}, Jsonrequestbehavior =Jsonrequestbehavior.allowget}; }            }            Else{Filtercontext.result=NewJsonresult {Data =New{title =false, message ="authentication error, Access denied"}, Jsonrequestbehavior =Jsonrequestbehavior.allowget}; }                    }    }

1.4 Method Body of the landing

[HttpPost] PublicJsonresult Login (checklogininput model) {if(model = =NULL||string. IsNullOrEmpty (model. PassWord) | | (string. IsNullOrEmpty (model. UserName) &&string. IsNullOrEmpty (model. Mobilephone )) {returnFail ("The submission parameter is incorrect"); } Checkloginoutput UA=_useraccountsappservice.checklogin (model); if(ua!=NULL&&ua. Id>0)            {                returnSuccess (Newtonsoft.Json.JsonConvert.SerializeObject (UA)); }            Else {                returnFail ("Login failed, account or password error"); }        }

The whole process is over.

AppendFormat ("account={0},mac={1},salt={2}", Uri.escapedatastring, uri.escapedatastring (getciphertext (account, Path, Date,password), date); returnsb.      ToString (); }
