我使用Angular2从Java Spring后端应用程序获取访问令牌。 我可以通过CURL获取令牌,但不能通过Angular形式获取。
curl localhost:8085/uaa/oauth/token --data "grant_type=password&scope=write&username=MY-USERNAME&password=MY-PASSWORD" --user user:pwd
我在Java后端启用了Cors:
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain chain) throws IOException, ServletException {
final HttpServletResponse response = (HttpServletResponse) servletResponse;
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Credentials", "true");
response.setHeader("Access-Control-Allow-Methods", "POST, PUT, DELETE, GET, HEAD, OPTIONS");
response.setHeader("Access-Control-Allow-Headers", "Origin, Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers, If-Modified-Since");
chain.doFilter(servletRequest, servletResponse);
}
My Angular代码如下所示:
import {Injectable, Component} from 'angular2/core';
import {Observable} from 'rxjs/Rx';
import {Http, HTTP_PROVIDERS, Headers} from 'angular2/http';
@Component({
viewProviders: [HTTP_PROVIDERS]
})
@Injectable()
export class Authentication {
token:string;
http:Http;
constructor(http:Http) {
this.token = localStorage.getItem('token');
this.http = http;
}
login(username:String, password:String) {
var url = 'http://localhost:8085/uaa/oauth/token',
body = JSON.stringify({
username: username,
password: password
}),
options = {
headers: new Headers({
'credentials': 'true',
'grant_type': 'password',
'scope': 'write',
'Accept': 'application/json',
'Content-Type': 'application/x-www-form-urlencoded'
})
};
return this.http.post(url, body, options)
.map((res:any) => {
let data = res.json();
this.token = data.token;
localStorage.setItem('token', this.token);
});
}
}
服务器的响应是:
Request URL:http://localhost:8085/uaa/oauth/token
Request Method:OPTIONS
Status Code:401 Unauthorized
Remote Address:[::1]:8085
答案 0 :(得分:7)
您可能有两个问题:
OPTIONS
来电是预检电话。 CORS标准规定预检调用不应包括身份验证。如果您的服务器未设置为处理该服务器,您将收到401
响应。如果您可以控制服务器,则应该能够添加一些内容以允许OPTIONS
调用。使用NGINX,您可以添加以下内容:
if ($request_method = 'OPTIONS') {return 200;}
不确定您是否是特定服务器。
您确定以正确的方式发送凭据吗?看起来您将所有这些作为单独的标头发送而不是像curl请求一样的表单编码数据。这对我有用:
var headers = new Headers();
headers.append('Content-Type', 'application/x-www-form-urlencoded');
var credentials = "grant_type=authorization_code
+ "&credentials=true"
+ "&scope=write"
/* etc. */
this.http.post('http://some.url', credentials, { headers: headers })
.subscribe((res) => token = res.json())
答案 1 :(得分:2)
您应该在授权标题中使用" Basic"提供用户名/密码提示。方案。该值必须使用带有btoa函数的base64编码:
headers.append('Authorization', 'Basic ' + btoa('username:password');
此外,在完成你的卷曲请求之后,似乎应该在有效负载中提供你放入标题的内容。这可以使用UrlSearchParams类完成。

这是正在运行的Nginx default.config的以下代码。
var time = target?.date ?: 0L
var calendar = Calendar.getInstance()
calendar.timeInMillis = time
LocalDate.ofYearDay(calendar.get(Calendar.YEAR), calendar.get(Calendar.DAY_OF_YEAR)).format(dateTimeFormatter)
答案 3 :(得分:0)
问题可能出在你的角度服务中。我认为您不应该将正文作为包含用户名和密码的对象发送,但是您应该发送包含" grant_type"," username"和#34;密码"。 这是我的工作服务方法的示例:
postAuth(url: string, data?: LoginCredentials){
let headers = new Headers({ 'Content-Type': 'application/x-www-form-urlencoded' });
let options = new RequestOptions({ headers: headers });
//here I am setting username and password which I got from html form
var body = "grant_type=password&username="+ data.Email +
"&password=" + data.Password;
return this.http.post(url, body, options);
}
