From f4057989f520daaef30b9d1cc0b0b0f12dbd7edc Mon Sep 17 00:00:00 2001 From: MHSanaei Date: Wed, 11 Feb 2026 21:32:23 +0100 Subject: Require HTTP 200 from curl before using IP Replace simple curl+trim checks with a response+http_code parse to ensure the remote URL returns HTTP 200 and a non-empty body before assigning server_ip. Changes applied to install.sh, update.sh and x-ui.sh: use curl -w to append the status code, extract http_code and ip_result, and only set server_ip when http_code == 200 and ip_result is non-empty. This makes the IP discovery more robust against error pages or partial responses while keeping the existing timeout behavior. --- update.sh | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) (limited to 'update.sh') diff --git a/update.sh b/update.sh index 0c4bb725..5dce0ce3 100755 --- a/update.sh +++ b/update.sh @@ -687,8 +687,11 @@ config_after_update() { ) local server_ip="" for ip_address in "${URL_lists[@]}"; do - server_ip=$(${curl_bin} -s --max-time 3 "${ip_address}" 2>/dev/null | tr -d '[:space:]') - if [[ -n "${server_ip}" ]]; then + local response=$(curl -s -w "\n%{http_code}" --max-time 3 "${ip_address}" 2>/dev/null) + local http_code=$(echo "$response" | tail -n1) + local ip_result=$(echo "$response" | head -n-1 | tr -d '[:space:]') + if [[ "${http_code}" == "200" && -n "${ip_result}" ]]; then + server_ip="${ip_result}" break fi done -- cgit v1.2.3
