Summary / 概述

Fixed Huawei Developer platform user detection by replacing CORS-blocked API approach with DOM extraction strategy. The previous method failed due to CORS policy restrictions when calling the delegate API.

Type of Change / 更改类型

• Bug fix / 修复 Bug (non-breaking change that fixes an issue / 修复问题的非破坏性更改)

Changes Made / 更改内容

• Replaced CSRF token-based API call with DOM extraction approach
• Updated manifest.json host permissions to include https://*.huawei.com/* and https://*.hicloud.com/*
• Removed dependency on developer_userinfo cookie parsing for CSRF token
• Implemented script injection to extract avatar and username from rendered DOM

Implementation Details / 实现细节

Key Changes / 主要更改:

• Changed detection strategy from API-based to DOM-based extraction
• Added chrome.scripting.executeScript to inject code into open Huawei Developer tabs
• Extract avatar from img#avatar-img element
• Extract username from .avatarArea spans with filtering logic to skip non-username text
• Convert avatar URL to base64 using convertAvatarToBase64 utility to bypass CORS/ORB restrictions

Technical Notes / 技术说明:

• The original approach failed because the delegate API (https://svc-drcn.developer.huawei.com/codeserver/Common/v1/delegate) blocks requests with CORS policy
• New approach requires an open developer.huawei.com tab to extract DOM elements
• Avatar conversion to base64 is necessary to avoid Opaque Response Blocking (ORB)
• Username extraction includes filtering logic to skip menu items and metadata (verified badge, level, post counts, etc.)

Additional Notes / 补充说明

This change requires users to have an open Huawei Developer tab for detection to work. If no tab is open, the detection will return logged-in status with empty username and avatar fields.
