我需要帮助,我尝试从响应中获取Cookie,但我无法找到方法,我对tsc和ng2很新。
这是ng2 http post
return this._http
.post('http://demo...', body, { headers: headers })
.subscribe(
(response: Response) => {
this.storeToken(response);
}, (err) => {
console.log('Error: ' + err);
}
);
这是服务器响应:
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Access-Control-Allow-Origin: http://localhost:3000
Access-Control-Allow-Credentials: true
Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With
Set-Cookie: JSESSIONID=A099CC4CA7A25DFBD12701630A7DC24C; Path=/pbcp/; HttpOnly
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked
Date: Fri, 17 Feb 2017 04:08:15 GMT
32
{"status":"OK","message":"User is Authenticated."}
0
我很困惑,因为我无法在标题数组中看到它......
console.log(response)
console.log(response.headers)
...,但我可以在cookies部分看到它。
谢谢!

嗯,经过一些研究,我发现了两个问题。
首先,Cookie已设置好,但我在错误的地方寻找它。这段时间我一直在我的localhost:3000
域下查看,并且cookie已正确存储在http://demo...
域下,这是正确的行为。我可以在chrome://settings/
==>中看到它显示高级设置==>所有Cookie和网站数据... ==>并通过远程主机进行过滤,如下所示:
第二次,我忘了在其余的请求标头中使用withCredentials: true
,以便自动包含和接受Cookie。
authenticate(username: string, password: string) {
var body = `{"username":"${username}","password":"${password}"}`;
var headers = new Headers();
headers.append('Content-Type', 'application/json');
let options = new RequestOptions({ headers: headers, withCredentials: true });
return this._http
.post('http://demo...', body, options)
.subscribe(
(response: Response) => {
this.doSomething(response);
}, (err) => {
console.log('Error: ' + err);
});
}
感谢@All的回复和时间!

我假设您正在使用angular2 http模块联系服务器,该服务器将返回带有服务器响应的observable。
如果您订阅,可以使用回复:
//...
http.post(...your content...)
.take(1) // optional: depending on your needs you could .take(x) this to just take a certain number of responses and then terminate the subscription in order to not have a "hot Observable" lying around
.subscribe(response =>{
.console.log(response);
// if I am not mistaken "response.headers" should contain the "Set-Cookie" you are looking for
});
您还可以将observable转换为Promise:
http.post(...your content...)
.toPromise()
.then(response=>{
console.log(response);
let headers = response.headers;
console.log(headers);
})
.catch(err=>console.log(err));
在某些响应情况下,您可能需要使用response.json()将其转换为检索和对象。
希望这会有所帮助。如果它不是你想要的东西给我一些更多的细节,我会尽力帮助。
