用GDScript实现扫码登陆Bilibili获取到SESSDATA

Fri, 08 May 2026 23:46:11 +0800

Godot中使用GDScript 实现 Bilibili 扫码登录获取 SESSDATA 流程

本文档总结 Godot 项目中通过 Bilibili 扫码登录获取 SESSDATA 的核心逻辑，代码位于脚本的 需要用户登陆 区域。

功能概述

调用 Bilibili 官方接口生成登录二维码，在应用内展示。
定时轮询二维码扫描状态，检测用户是否已扫码并确认登录。
扫码成功后通过登录链接交换得到 SESSDATA，并持久化到项目存储中。
提供回调机制通知调用方登录结果（成功/失败）。

源代码

# 扫码登录相关变量
var qr_window: Window = null
var _poll_timer: Timer
var on_qr_login_result: Callable
func start_qr_login(login_callback: Callable) -> void:
on_qr_login_result = login_callback

var data = json.get_data()["data"]
var url = data["url"]
var qrcode_key = data["qrcode_key"]

_poll_timer.autostart = true
_poll_timer.timeout.connect(_check_qr_status.bind(qrcode_key))
add_child(_poll_timer)
func _check_qr_status(qrcode_key: String) -> void:
var http = HTTPRequest.new()
add_child(http)
http.request_completed.connect(func(result, response_code, headers, body):
if response_code != 200: return
var json = JSON.new()
if json.parse(body.get_string_from_utf8()) != OK: return
var data = json.get_data()["data"]
var code = data["code"]
if code == 0:
_exchange_cookie(data["url"])
if on_qr_login_result:

_close_qr_window()
elif code == 86038:
if on_qr_login_result:

_close_qr_window()
)
http.request("https://passport.bilibili.com/x/passport-login/web/qrcode/poll?qrcode_key=" + qrcode_key, PackedStringArray(), HTTPClient.METHOD_GET)
func _exchange_cookie(login_url: String) -> void:
var http = HTTPRequest.new()
add_child(http)
http.request_completed.connect(func(result, response_code, headers, body):
for header in headers:
if header.begins_with("Set-Cookie: SESSDATA="):
var sess = header.split("=")[1].split(";")[0]
GdScriptFunc.set_data("AccountData","SESSDATA",sess)
break
)
http.request(login_url, PackedStringArray(), HTTPClient.METHOD_GET)

核心流程

发起登录
调用 start_qr_login(login_callback) 开始流程，传入一个回调函数用于接收登录结果。

Godot Windows平台如何自动处理鼠标穿透

可以利用DllImport导入SetWindowLong来设置窗口样式

具体代码:

WindowsApiManager.cs

using System.Runtime.InteropServices;
using Godot;

public partial class WindowsApiManager : Node
{
 private nint _hWnd;

 [DllImport("user32.dll")]
 public static extern nint GetActiveWindow();

 [DllImport("user32.dll")]
 private static extern int SetWindowLong(nint hWnd, int nIndex, uint dwNewLong);

 public override void _Ready()
 {
 _hWnd = GetActiveWindow();
 _ = SetWindowLong(_hWnd, -20, 524416u);
 }

 public void SetClickThrough(bool clickthrough)
 {
 if (clickthrough)
 {

 _ = SetWindowLong(_hWnd, -20, 524448u);
 }
 else
 {
 _ = SetWindowLong(_hWnd, -20, 524416u);
 }
 }
}

MouseDetection.cs

using Godot;

public partial class MouseDetection : Node
{
 private WindowsApiManager _api;

 private bool _clickthrough = true;

 public override void _Ready()
 {
 _api = GetNode<WindowsApiManager>("/root/WindowsApiManager");
 _api.SetClickThrough(clickthrough: true);
 }

 public override void _PhysicsProcess(double _)
 {
 DetectPassthrough();
 }

 private void DetectPassthrough()
 {
 Viewport viewport = GetViewport();
 Image img = viewport.GetTexture().GetImage();
 Rect2 rect = viewport.GetVisibleRect();
 Vector2 mousePosition = viewport.GetMousePosition();
 int viewX = (int)((int)mousePosition.X + rect.Position.X);
 int viewY = (int)((int)mousePosition.Y + rect.Position.Y);
 int x = (int)(img.GetSize().X * viewX / rect.Size.X);
 int y = (int)(img.GetSize().Y * viewY / rect.Size.Y);
 if (x < img.GetSize().X && x >= 0 && y < img.GetSize().Y && y >= 0)
 {
 SetClickability(img.GetPixel(x, y).A >= 1f);
 }
 img.Dispose();
 }

 private void SetClickability(bool clickable)
 {
 if (clickable != _clickthrough)
 {
 _clickthrough = clickable;
 _api.SetClickThrough(!clickable);
 }
 }
}

使用方法:

将WindowsApiManager.cs设为自动加载脚本
