使用 Java 11 HttpClient 设置会话 cookie
Setting a session cookie with the Java 11 HttpClient
我正在尝试使用 Java 11 HttpClient 获取页面内容。由于该页面使用 OAuth，我想使用我的会话 cookie 进行身份验证。我目前使用以下代码，灵感来自 this question:
public static void main(String[] args) throws IOException, InterruptedException {
String year = args[0];
String day = args[1];
String session = System.getenv("AOCSESSION");
System.out.println(session);
HttpRequest req = HttpRequest.newBuilder()
.uri(URI.create("https://adventofcode.com/"+year+"/day/"+day+"/input")).GET().build();
CookieManager cookieManager = new CookieManager();
HttpCookie cookie = new HttpCookie("session", session);
cookieManager.getCookieStore().add(URI.create("https://adventofcode.com"), cookie);
HttpClient client = HttpClient.newBuilder().cookieHandler(cookieManager).build();
String body = client.send(req, BodyHandlers.ofString()).body();
System.out.println(body);
}
但是，这些请求未经身份验证（响应：Puzzle inputs differ by user. Please log in to get your puzzle input.）。我已经尝试向 cookie 添加其他字段：
cookie.setDomain(".adventofcode.com");
cookie.setMaxAge(Instant.parse("2031-11-01T18:26:23.293Z").getEpochSecond());
cookie.setPath("/");
cookie.setHttpOnly(true);
cookie.setSecure(true);
但是并没有解决问题。
如何向请求添加会话 cookie？
下面的解决方案是使用适当的 CookieManager 而不是硬编码 header:
public static void main(String[] args) throws Exception {
CookieHandler.setDefault(new CookieManager());
HttpCookie sessionCookie = new HttpCookie("session", "53616c7465645f5f9d467d3ae831ec1b1e7289ef45d256224786e1ed13");
sessionCookie.setPath("/");
sessionCookie.setVersion(0);
((CookieManager) CookieHandler.getDefault()).getCookieStore().add(new URI("https://adventofcode.com"),
sessionCookie);
HttpClient client = HttpClient.newBuilder()
.cookieHandler(CookieHandler.getDefault())
.connectTimeout(Duration.ofSeconds(10))
.build();
HttpRequest req = HttpRequest.newBuilder()
.uri(URI.create("https://adventofcode.com/2020/day/1/input"))
.GET().build();
System.out.println(client.send(req, HttpResponse.BodyHandlers.ofString()).body());
}
sessionCookie.setPath("/"); 重要：Java 有 CookieFilter，它实际上匹配请求 URI 路径，而不是 Cookie 路径。
sessionCookie.setVersion(0); 重要提示：本站不喜欢版本 1（HttpCookie 默认，符合 RFC 2965/2109）
版本 0 符合原始 Netscape cookie，AdventOfCode 喜欢它。
版本 0 和版本 1 之间的区别在于 Cookie 的外观：
版本 0：
INFO: HEADERS: HEADERS FRAME (stream=1)
:authority: adventofcode.com
:method: GET
:path: /2020/day/1/input
:scheme: https
Cookie: session=53616c7465645f5f9d467....
User-Agent: Java-http-client/11.0.7
版本 1：
INFO: HEADERS: HEADERS FRAME (stream=1)
:authority: adventofcode.com

User-Agent: Java-http-client/11.0.7
版本 1 将从网站抛出 500 服务器错误。

Java 11 HttpClient in-built 支持 Session-Cookie。如果您像这样创建一个客户端：
var client = HttpClient.newBuilder()
.cookieHandler(new CookieManager())
.version(HttpClient.Version.HTTP_2)
.build();
然后客户端会自动保存第一次授权请求中的所有cookies。此客户端发出的任何后续请求都将设置 cookie。
或
如果您想在发送初始请求之前为 cookie 设置一些值，请尝试：
var cookieManager = new cookieManager();
cookieManager.getCookieStore().add(someHostURI, someSessionCookie);
//Now this cookie can be used to create the client:
var client = HttpClient.newBuilder()
.cookieHandler(cookieManager)
.version(HttpClient.Version.HTTP_2)
.build();
有关更详细的说明，请查看 this article。
我正在尝试使用 Java 11 HttpClient 获取页面内容。由于该页面使用 OAuth，我想使用我的会话 cookie 进行身份验证。我目前使用以下代码，灵感来自 this question:
public static void main(String[] args) throws IOException, InterruptedException {
String year = args[0];
String day = args[1];
String session = System.getenv("AOCSESSION");
System.out.println(session);
HttpRequest req = HttpRequest.newBuilder()
.uri(URI.create("https://adventofcode.com/"+year+"/day/"+day+"/input")).GET().build();
CookieManager cookieManager = new CookieManager();
HttpCookie cookie = new HttpCookie("session", session);
cookieManager.getCookieStore().add(URI.create("https://adventofcode.com"), cookie);
HttpClient client = HttpClient.newBuilder().cookieHandler(cookieManager).build();
String body = client.send(req, BodyHandlers.ofString()).body();
System.out.println(body);
}
但是，这些请求未经身份验证（响应：Puzzle inputs differ by user. Please log in to get your puzzle input.）。我已经尝试向 cookie 添加其他字段：
cookie.setDomain(".adventofcode.com");
cookie.setMaxAge(Instant.parse("2031-11-01T18:26:23.293Z").getEpochSecond());
cookie.setPath("/");
cookie.setHttpOnly(true);
cookie.setSecure(true);
但是并没有解决问题。
如何向请求添加会话 cookie？
下面的解决方案是使用适当的 CookieManager 而不是硬编码 header:
public static void main(String[] args) throws Exception {
CookieHandler.setDefault(new CookieManager());
HttpCookie sessionCookie = new HttpCookie("session", "53616c7465645f5f9d467d3ae831ec1b1e7289ef45d256224786e1ed13");
sessionCookie.setPath("/");
sessionCookie.setVersion(0);
((CookieManager) CookieHandler.getDefault()).getCookieStore().add(new URI("https://adventofcode.com"),
sessionCookie);
HttpClient client = HttpClient.newBuilder()
.cookieHandler(CookieHandler.getDefault())
.connectTimeout(Duration.ofSeconds(10))
.build();
HttpRequest req = HttpRequest.newBuilder()

System.out.println(client.send(req, HttpResponse.BodyHandlers.ofString()).body());

sessionCookie.setPath("/"); 重要：Java 有 CookieFilter，它实际上匹配请求 URI 路径，而不是 Cookie 路径。
sessionCookie.setVersion(0); 重要提示：本站不喜欢版本 1（HttpCookie 默认，符合 RFC 2965/2109）
版本 0 符合原始 Netscape cookie，AdventOfCode 喜欢它。
版本 0 和版本 1 之间的区别在于 Cookie 的外观：
版本 0：

Java 11 HttpClient in-built 支持 Session-Cookie。如果您像这样创建一个客户端：
var client = HttpClient.newBuilder()
.cookieHandler(new CookieManager())
.version(HttpClient.Version.HTTP_2)
.build();
然后客户端会自动保存第一次授权请求中的所有cookies。此客户端发出的任何后续请求都将设置 cookie。
或
如果您想在发送初始请求之前为 cookie 设置一些值，请尝试：
var cookieManager = new cookieManager();
cookieManager.getCookieStore().add(someHostURI, someSessionCookie);
//Now this cookie can be used to create the client:
var client = HttpClient.newBuilder()
.cookieHandler(cookieManager)
.version(HttpClient.Version.HTTP_2)
.build();
有关更详细的说明，请查看 this article。
