备注： 默认没有集成到nginx包里，需要单独安装（推荐使用动态模块的方式进行安装）
1. 安装
wget https://nginx.org/download/nginx-1.13.11.tar.gzhg clone http://hg.nginx.org/njs // njs 模块克隆./configure --add-module=path-to-njs/nginx构建模块make modules 安装模块make install备注：需要一些预备准备 pcre openssl
2. 配置加载模块
load_module modules/ngx_http_js_module.so; // 加载模块，注意顺序#user nobody;worker_processes 1;events { worker_connections 1024;}http { include mime.types; default_type text/html; sendfile on; keepalive_timeout 65; #gzip on; server { listen 80; server_name localhost; location / { root html; index index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } }} 顺序
3. 使用指令
js_include ../js/http.js;js_set $foo foo;js_set $summary summary;server { listen 8000; location / { add_header X-Foo $foo; js_content baz; } location /summary { return 200 $summary; }}http.jsfunction foo(req, res) { req.log("hello from foo() handler"); return "foo";}function summary(req, res) { var a, s, h; s = "JS summary\n\n"; s += "Method: " + req.method + "\n"; s += "HTTP version: " + req.httpVersion + "\n"; s += "Host: " + req.headers.host + "\n"; s += "Remote Address: " + req.remoteAddress + "\n"; s += "URI: " + req.uri + "\n"; s += "Headers:\n"; for (h in req.headers) { s += " header '" + h + "' is '" + req.headers[h] + "'\n"; } s += "Args:\n"; for (a in req.args) { s += " arg '" + a + "' is '" + req.args[a] + "'\n"; } return s;}function baz(req, res) { res.headers.foo = 1234; res.status = 200; res.contentType = "text/plain; charset=utf-8"; res.contentLength = 15; res.sendHeader(); res.send("nginx"); res.send("java"); res.send("script"); res.finish();} 4. 测试
sbin/nginx -t sbin/nginx -s reload访问测试地址http://hostip:8000http://hostip:8000/summary
测试结果
5. 总结
目前来说已经支持了好多es 语法，如果能够更好的集成nodejs模块节能会更好，同时相比openresty 功能上还是太差了，实际使用上，还是openresty 更好
