原配置 server { listen 80; server_name 127.0.0.1; location /gwzt/ { proxy_pass http://127.0.0.1:3000/gwzt/; } } 分析 请求首先被发送到 http://外网:8889/gwzt（希望的地址）。 然后，nginx 将其重定向到 http://外网:80/gwzt。 导致服务无法访问。 调整配置 server { listen 8889; # 监听8889端口，确保是外网访问端口 server_name 127.0.0.1; location /gwzt/ { proxy_pass http://127.0.0.1:3000/gwzt/; } } server { listen 80; # 监听80端口，内部访问 server_name 127.0.0.1; location /gwzt/ { proxy_pass http://127.0.0.1:3000/gwzt/; } }

window.onerror = handleError function handleError(msg, url, l) { var txt = "There was an error on this page.\n\n"; txt += "Error: " + msg + "\n"; txt += "URL: " + url + "\n"; txt += "Line: " + l + "\n\n"; txt += "Click OK to continue.\n\n"; alert(msg); return true; }
