angie njs 模块试用

angie njs 是一个类似lua 的模块，提供了基于js 进行nginx 功能开发的能力（但是目前没有nginx lua 模块强大）
以下是一个简单试用

环境准备

基于了以前测试nginx lua 模块的基础镜像

  • http.js
 
function foo(r) {
    r.log("hello from foo() handler");
    return "foo";
}
 
function summary(r) {
    var a, s, h;
 
    s = "JS summary\n\n";
 
    s += "Method: " + r.method + "\n";
    s += "HTTP version: " + r.httpVersion + "\n";
    s += "Host: " + r.headersIn.host + "\n";
    s += "Remote Address: " + r.remoteAddress + "\n";
    s += "URI: " + r.uri + "\n";
 
    s += "Headers:\n";
    for (h in r.headersIn) {
        s += "  header '" + h + "' is '" + r.headersIn[h] + "'\n";
    }
 
    s += "Args:\n";
    for (a in r.args) {
        s += "  arg '" + a + "' is '" + r.args[a] + "'\n";
    }
 
    return s;
}
 
function baz(r) {
    r.status = 200;
    r.headersOut.foo = 1234;
    r.headersOut['Content-Type'] = "text/plain; charset=utf-8";
    r.headersOut['Content-Length'] = 15;
    r.sendHeader();
    r.send("nginx");
    r.send("java");
    r.send("script");
 
    r.finish();
}
 
function hello(r) {
    r.return(200, "Hello world!");
}
 
// since 0.7.0
async function hash(r) {
    let hash = await crypto.subtle.digest('SHA-512', r.headersIn.host);
    r.setReturnValue(Buffer.from(hash).toString('hex'));
}
 
export default {foo, summary, baz, hello, hash};

  • 效果

说明

njs 模块目前提供的能力还是比较方便的，同时我们也可以试用typescript 进行模块的开发，这样也就具有了强类型的能力，还是很不错的
