hi-nginx-1.4.9正式釋出,支援javascript後端開發

hi-nginx-1.4.9已經釋出。

更新：

• 支援javascript後端開發
• 修複腳本搜尋的一個bug

從這一版開始，hi-nginx開始支援javascript，這意味着把javascript應用于後端開發，将不再隻有nodejs這唯一的途徑和方法。由于java本身對javascript的極好支援，使得在hi-nginx中，可以直接在javascript腳本中使用java——相當于把java嵌入了javascript。

為了開啟javascript支援，你隻需要開啟java支援即可：--enable-http-hi-java=YES。

例子：

if (typeof (Mustache) == 'undefined') {
    load('https://cdn.bootcss.com/mustache.js/2.3.0/mustache.min.js')
}


var list = java.util.Arrays.asList(0, 1, 2, 3, 4, 5, 6, 7, 8, 9);
var template = "{{#list}}* {{.}}\n{{/list}}"
var key = 'test', output
if (hi_req.cache.containsKey(key)) {
    output = hi_req.cache.get(key)
} else {
    output = Mustache.render(template, {'list': JSON.parse(list.toString())})
    hi_res.cache.put(key, output)
}
hi_res.headers.get('Content-Type').set(0, 'text/plain;charset=UTF-8')
hi_res.content = output
hi_res.status = 200;

ab -c 1000 -n 500000 壓力測試,RPS:

• nodejs(6.12.0):無法完成測試
• hi-nginx-javascript :均值13000+

ab -c 1000 -n 100000 壓力測試,RPS:

• nodejs(6.12.0):偶爾完成測試，最好成績接近9000+,均值6000-9000
• hi-nginx-javascript :均值14000+

        hi_java_servlet_cache_size 10;
        hi_java_version 8;


        location / {
                hi_need_cache off;

                hi_javascript_lang javascript;
                hi_javascript_extension js;
                #hi_javascript_script javascript/index.js;
                hi_javascript_content "hi_res.content='hello,world';hi_res.status=200;";
