[英]How to call web API login action from Windows form app
I have a simple web API with registration, login, and call API module. 我有一个简单的Web API,包含注册,登录和调用API模块。 I want to call each functionality from Windows form application.
我想从Windows表单应用程序调用每个功能。
In web API, I use the following script in JavaScript to call login method: 在Web API中,我使用JavaScript中的以下脚本来调用登录方法:
self.login = function () {
self.result('');
var loginData = {
grant_type: 'password',
username: self.loginEmail(),
password: self.loginPassword()
};
$.ajax({
type: 'POST',
url: '/Token',
data: loginData
}).done(function (data) {
self.user(data.userName);
// Cache the access token in session storage.
sessionStorage.setItem(tokenKey, data.access_token);
}).fail(showError);
}
my controller actions are as follows 我的控制器动作如下
// POST api/Account/AddExternalLogin
[Route("AddExternalLogin")]
public async Task<IHttpActionResult> AddExternalLogin(AddExternalLoginBindingModel model)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
Authentication.SignOut(DefaultAuthenticationTypes.ExternalCookie);
AuthenticationTicket ticket = AccessTokenFormat.Unprotect(model.ExternalAccessToken);
if (ticket == null || ticket.Identity == null || (ticket.Properties != null
&& ticket.Properties.ExpiresUtc.HasValue
&& ticket.Properties.ExpiresUtc.Value < DateTimeOffset.UtcNow))
{
return BadRequest("External login failure.");
}
ExternalLoginData externalData = ExternalLoginData.FromIdentity(ticket.Identity);
if (externalData == null)
{
return BadRequest("The external login is already associated with an account.");
}
IdentityResult result = await UserManager.AddLoginAsync(User.Identity.GetUserId(),
new UserLoginInfo(externalData.LoginProvider, externalData.ProviderKey));
if (!result.Succeeded)
{
return GetErrorResult(result);
}
return Ok();
}
// POST api/Account/RemoveLogin
[Route("RemoveLogin")]
public async Task<IHttpActionResult> RemoveLogin(RemoveLoginBindingModel model)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
IdentityResult result;
if (model.LoginProvider == LocalLoginProvider)
{
result = await UserManager.RemovePasswordAsync(User.Identity.GetUserId());
}
else
{
result = await UserManager.RemoveLoginAsync(User.Identity.GetUserId(),
new UserLoginInfo(model.LoginProvider, model.ProviderKey));
}
if (!result.Succeeded)
{
return GetErrorResult(result);
}
return Ok();
}
// GET api/Account/ExternalLogin
[OverrideAuthentication]
[HostAuthentication(DefaultAuthenticationTypes.ExternalCookie)]
[AllowAnonymous]
[Route("ExternalLogin", Name = "ExternalLogin")]
public async Task<IHttpActionResult> GetExternalLogin(string provider, string error = null)
{
if (error != null)
{
return Redirect(Url.Content("~/") + "#error=" + Uri.EscapeDataString(error));
}
if (!User.Identity.IsAuthenticated)
{
return new ChallengeResult(provider, this);
}
ExternalLoginData externalLogin = ExternalLoginData.FromIdentity(User.Identity as ClaimsIdentity);
if (externalLogin == null)
{
return InternalServerError();
}
if (externalLogin.LoginProvider != provider)
{
Authentication.SignOut(DefaultAuthenticationTypes.ExternalCookie);
return new ChallengeResult(provider, this);
}
ApplicationUser user = await UserManager.FindAsync(new UserLoginInfo(externalLogin.LoginProvider,
externalLogin.ProviderKey));
bool hasRegistered = user != null;
if (hasRegistered)
{
Authentication.SignOut(DefaultAuthenticationTypes.ExternalCookie);
ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(UserManager,
OAuthDefaults.AuthenticationType);
ClaimsIdentity cookieIdentity = await user.GenerateUserIdentityAsync(UserManager,
CookieAuthenticationDefaults.AuthenticationType);
AuthenticationProperties properties = ApplicationOAuthProvider.CreateProperties(user.UserName);
Authentication.SignIn(properties, oAuthIdentity, cookieIdentity);
}
else
{
IEnumerable<Claim> claims = externalLogin.GetClaims();
ClaimsIdentity identity = new ClaimsIdentity(claims, OAuthDefaults.AuthenticationType);
Authentication.SignIn(identity);
}
return Ok();
}
// GET api/Account/ExternalLogins?returnUrl=%2F&generateState=true
[AllowAnonymous]
[Route("ExternalLogins")]
public IEnumerable<ExternalLoginViewModel> GetExternalLogins(string returnUrl, bool generateState = false)
{
IEnumerable<AuthenticationDescription> descriptions = Authentication.GetExternalAuthenticationTypes();
List<ExternalLoginViewModel> logins = new List<ExternalLoginViewModel>();
string state;
if (generateState)
{
const int strengthInBits = 256;
state = RandomOAuthStateGenerator.Generate(strengthInBits);
}
else
{
state = null;
}
foreach (AuthenticationDescription description in descriptions)
{
ExternalLoginViewModel login = new ExternalLoginViewModel
{
Name = description.Caption,
Url = Url.Route("ExternalLogin", new
{
provider = description.AuthenticationType,
response_type = "token",
client_id = Startup.PublicClientId,
redirect_uri = new Uri(Request.RequestUri, returnUrl).AbsoluteUri,
state = state
}),
State = state
};
logins.Add(login);
}
return logins;
}
I am using the following code in winform to call the login action: 我在winform中使用以下代码来调用登录操作:
HttpClient client = new HttpClient();
Uri baseAddress = new Uri("https://localhost:44305/");
client.BaseAddress = baseAddress;
ArrayList paramList = new ArrayList();
user u = new user();
u.username = username;
u.password = password;
paramList.Add(u);
HttpResponseMessage response = client.PostAsJsonAsync("api/product/SupplierAndProduct", paramList).Result;
In the above code I tried to call controller actions but failed. 在上面的代码中,我尝试调用控制器操作但失败了。 To accomplish my goal even calling the JavaScript from winform app is fine.
要实现我的目标,即使从winform应用程序调用JavaScript也没问题。
HttpClient client = new HttpClient();
Uri baseAddress = new Uri("http://localhost:2939/");
client.BaseAddress = baseAddress;
ArrayList paramList = new ArrayList();
Product product = new Product { ProductId = 1, Name = "Book", Price = 500, Category = "Soap" };
Supplier supplier = new Supplier { SupplierId = 1, Name = "AK Singh", Address = "Delhi" };
paramList.Add(product);
paramList.Add(supplier);
HttpResponseMessage response = client.PostAsJsonAsync("api/product/SupplierAndProduct", paramList).Result;
I usually use HttpWebRequest
and HttpWebResponce
in cases like yours: 我通常在像你这样的情况下使用
HttpWebRequest
和HttpWebResponce
:
//POST
var httpWebRequest = (HttpWebRequest)WebRequest.Create("path/api");
httpWebRequest.ContentType = "text/json";
httpWebRequest.Method = WebRequestMethods.Http.Post;
httpWebRequest.Accept = "application/json; charset=utf-8";
//probably have to be added
//httpWebRequest.ContentLength = json.Length;
//do request
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
//write post data
//also you can serialize yours objects by JavaScriptSerializer
streamWriter.Write(json);
streamWriter.Flush();
}
//get responce
using (var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse())
{
//read
using (Stream stream = httpResponse.GetResponseStream())
{
using (StreamReader re = new StreamReader(stream))
{
String jsonResponce = re.ReadToEnd();
}
}
}
//GET
var httpWebRequest = (HttpWebRequest)WebRequest.Create("path/api");
httpWebRequest.ContentType = "text/json";
httpWebRequest.Method = WebRequestMethods.Http.Get;
httpWebRequest.Accept = "application/json; charset=utf-8";
//get responce
using (var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse())
{
//read
using (Stream stream = httpResponse.GetResponseStream())
{
using (StreamReader re = new StreamReader(stream))
{
String jsonResponce = re.ReadToEnd();
}
}
}
Following answer will helpfull to you 以下答案对您有所帮助
//GET
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://160.114.10.17:85/api/Inventory/GetProcessDataByProcessName?deviceCode=OvCHY1ySowF4T2bb8HdcYA==&processName=Main Plant");
httpWebRequest.ContentType = "text/json";
httpWebRequest.Method = WebRequestMethods.Http.Get;
httpWebRequest.Accept = "application/json; charset=utf-8";
//get responce
using (var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse())
{
//read
using (Stream stream = httpResponse.GetResponseStream())
{
using (StreamReader re = new StreamReader(stream))
{
String jsonResponce = re.ReadToEnd();
}
}
}
