我正在尝试从外部API获取令牌,当我尝试登录Web应用程序以及尝试通过邮递员发送请求时,此方法有效。对于此请求,我需要将内容类型设置为x-www-form-urlencoded
。我知道如何执行此操作,但它似乎总是返回一个400错误的请求,并告诉我grant_type无效。因此,开始执行此任务的方法如下,将在登录时调用该代码:
代码如下:-
var _login = function (loginData) {
var data = ["grant_type=password&username=", loginData.userName, "&password=", loginData.password].join('');
var deferred = $q.defer();
$http.post([serviceBase, "token"].join(''), data, { headers: { "Content-Type": "application/x-www-form-urlencoded" } }).success(function (response) {
console.log("login response", response);
localStorageService.set(_keyAuthorizationData, { token: response.access_token, userName: loginData.userName });
_authentication.isAuth = true;
_authentication.userName = loginData.userName;
deferred.resolve(response);
}).error(function (err, status) {
_logOut();
deferred.reject(err);
});
return deferred.promise;
};
loginData将由登录表单中的数据填充。
这是我对外部API的另一个调用,该API返回了400错误请求
var _transferPersoon = function (portal, data) {
var externalAPI = "";
if (portal == "portal1") {
externalAPI = "https://urltoportal/webapi/";
} else if (portal == "portal2") {
externalAPI = "https://urltoportal/webapi/";
} else if (portal == "portal3") {
externalAPI = "https://urltoportal/webapi/";
} else if (portal == "portal4") {
externalAPI = "https://urltoportal/webapi/";
} else {
externalAPI = serviceBase;
}
var tokenData = {
username: "cactustransfer",
password: "bbbbbb",
grant_type: "password"
};
var data = ["grant_type=password&username=", "transferaccount", "&password=", "password"].join('');
$http.post([externalAPI, "token"].join(''), data, { headers: { "Content-Type": "application/x-www-form-urlencoded" } }).success(function (response) {
return response.access_token;
})
}
这是返回并显示在Google chrome中的错误:
{错误:“ unsupported_grant_type”}
此请求正在通过我的ASP.NET Web API中的身份验证中间件发送和传递:
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
Cactus.Business.DataModel.GEBRUIKER gebruiker = null;
context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] {"*"});
var identity = new ClaimsIdentity(context.Options.AuthenticationType);
/*
* Authenticatie methode voor het verplaatsen van personeel
* Deze kan niet uitgevoerd worden als het request IP niet in het lijstje van hosts staat.
* Dit is een extra beveiliging.
*/
if (context.UserName == "cactustransfer")
{
if (!hostVerify.IsValidHost(context.Request.RemoteIpAddress))
{
using (UnitOfWork work = new UnitOfWork())
{
gebruiker = work.GebruikerRepository.ValidateUser("transferaccount", "password");
}
}
}
if (gebruiker == null)
{
using (UnitOfWork work = new UnitOfWork())
{
gebruiker = work.GebruikerRepository.ValidateUser(context.UserName, context.Password);
if (gebruiker == null)
{
context.SetError("invalid_grant",
"The username or password is incorrect, or you have insufficient rights", context.Request.RemoteIpAddress);
return;
}
}
}
identity.AddClaim(new Claim("sub", context.UserName));
identity.AddClaim(new Claim("role", "user"));
identity.AddClaim(new Claim("providerID", gebruiker.gebruikerId.ToString()));
//identity.AddClaim(new Claim("providerID", gebruiker.persoon.ToString()));
context.Validated(identity);
}
这是我对邮递员及其结果进行测试的要求:
我已经检查并尝试了以下解决方案:
How do I POST urlencoded form data with $http without jQuery?
https://github.com/thephpleague/oauth2-server/issues/261
注意 我在Postman中使用的用户名实际上与transferaccount用户名相同
编辑:
这是Google chrome中显示的请求标头,第一个是登录名,它与本地API通信,第二个是尝试向外部API发送请求
更新:
有关使用外部API处理数据的所有功能已移至本地ASP.NET WEB API。这样,我知道如何使其工作。但这并不是真正的解决方案,而是一种解决方法。
答案 0 :(得分:0)
尝试一下:
$http.post([externalAPI, "token", "?", data].join(''), {}, { headers: { "Content-Type": "application/x-www-form-urlencoded" } }).success(function (response) {
return response.access_token;
})
