From dd8fce6e358fb46f8b9f6d13267414266078aa1c Mon Sep 17 00:00:00 2001 From: Kelly Date: Fri, 12 Dec 2025 02:13:51 -0700 Subject: [PATCH] fix(proxy): Convert non-standard proxy URL format and simplify preflight MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - CrawlRotator.getProxyUrl() now converts non-standard format (http://host:port:user:pass) to standard format (http://user:pass@host:port) - Simplify puppeteer preflight to only use ipify.org for IP verification (much lighter than fingerprint.com) - Remove heavy anti-detect site tests from preflight - not needed, trust stealth plugin - Fixes 503 errors when using session-based residential proxies 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- backend/src/scripts/import-proxies.ts | 53 +++-- backend/src/services/crawl-rotator.ts | 12 +- backend/src/services/puppeteer-preflight.ts | 231 ++------------------ 3 files changed, 67 insertions(+), 229 deletions(-) diff --git a/backend/src/scripts/import-proxies.ts b/backend/src/scripts/import-proxies.ts index acdc5d75..525daa96 100644 --- a/backend/src/scripts/import-proxies.ts +++ b/backend/src/scripts/import-proxies.ts @@ -133,19 +133,35 @@ async function importProxies(proxies: ParsedProxy[], maxConnections: number, dry // Determine if we need to store the raw URL (non-standard format) const needsRawUrl = isNonStandardFormat(proxy.rawUrl); - const result = await pool.query(` - INSERT INTO proxies (host, port, protocol, username, password, max_connections, proxy_url, active) - VALUES ($1, $2, $3, $4, $5, $6, $7, true) - ON CONFLICT (host, port, protocol) - DO UPDATE SET - username = EXCLUDED.username, - password = EXCLUDED.password, - max_connections = EXCLUDED.max_connections, - proxy_url = EXCLUDED.proxy_url, - active = true, - updated_at = NOW() - RETURNING id, (xmax = 0) as is_insert - `, [ + // Use different conflict resolution based on format + // Non-standard format: unique by proxy_url (session-based residential proxies) + // Standard format: unique by host/port/protocol + const query = needsRawUrl + ?
