目标
目标是使用HTTP基本身份验证调用远程登录服务并获取JSESSIONID
以便进一步使用。
已测试的后端
到目前为止,我已经成功调用了服务,并得到了200
响应。我的restassured测试工作顺利,并表明登录服务已经正确提供了JSESSIONID
。Spring后端服务带有@CrossOrigin
注解。
// assure we are not logged in
RestAssured.baseURI = "https://" + ip;
RestAssured.basePath = "/user";
Response responseA = post("/create"); // /user/create is a secured service
assertEquals(401, responseA.statusCode());
// log in and save the token
RestAssured.baseURI = "https://" + username + ":pass@" + ip; // http basic auth is used
RestAssured.basePath = "/user";
Response responseB = post("/login");
assertEquals(200, responseB.statusCode());
String jsessionId = responseB.getCookie("JSESSIONID");
// C50C28EA1F3ABBB76F0E4189A772A4E9
RestAssured.baseURI = "https://" + ip;
RestAssured.basePath = "/user";
// call a service without token or credentials --> 401
Response responseC = get("/id"); // /user/id is a secured service
assertEquals(401, responseC.statusCode());
// call a service with the token
RestAssured.sessionId = jsessionId;
Response responseD = get("/id");
assertEquals(200, responseD.statusCode());
测试通过。
前端问题
在我们的Angular2前端应用程序中,我们有一个登录页面,其提交按钮通过onSubmit()
方法运行以下代码。
_url = "theLoginServiceUrl"
createAuthorizationHeader(username: string, password: string, headers:Headers) {
headers.append('Authorization', 'Basic ' + btoa(username + ':' + password));
// tried all of these, but they didn't fix the problem
// headers.append('Access-Control-Allow-Origin', '*');
// headers.append('Access-Control-Allow-Headers', '*');
// headers.append('Access-Control-Allow-Methods', '*');
}
login (username: string, password: string) {
let headers = new Headers();
this.createAuthorizationHeader(username, password, headers);
return this._http.post(this._url, "", {
headers: headers
});
}
onSubmit() {
this.login(this.currentUser.username, this.currentUser.password)
.subscribe((res) => {
var headers = res.headers;
console.log(headers);
// Headers {_headersMap: Map}
// <entries>[3]
// {"Pragma" => Array[1]}
// {"Cache-Control" => Array[1]}
// {"Expires" => Array[1]}
var setCookieHeader = headers.get('Set-Cookie');
console.log(setCookieHeader)
// null
}
);
}
从评论中可以看出,我无法访问Set-Cookie
头。然而,在浏览器中,我能看到包含Set-Cookie
头的成功调用:
HTTP/1.1 200 OK

X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block

请注意这一切都是通过 HTTPS
运行的。
前端细节:
"typescript": "^1.7.5"
"angular2": "2.0.0-beta.7"
问题:
为什么我不能在我的Angular2代码中访问Set-Cookie
?我需要改变什么?
