有道字典的chrome extension会把鼠标下的词log到console里,debug的时候让人烦, 看了下code, 直接用的console.log, 发布的时候也没注释掉. 跑到~/Library/Application Support/Google/Chrome/Default/Extensions/nbndkplefmmhmcmfjanjaakhhkiegogd/1.0_0下把content.js,background.html里的console.log都注释掉,安静了。
大概看了下extension code, 发现两个有意思的地方:

- 取词的时候调用的是本机有道字典app提供的http接口

function SendResult(word, pos, type) {
var s = new XMLHttpRequest;
s.open("GET", "http://localhost:32445/getword?word=" + word + "&pos=" + pos + "&type=" + type, true);
//console.log('sending...')
s.send()
};

用curl试了下,可以发送请求,但响应为空

word, pos, type这三个参数只要少一个有道字典就会crash
这次http request只是一个trigger, 有道字典会向dict.youdao.com发一个request:

拿到结果后由有道字典显示一个提示窗口.
这种实现方式倒也算精巧, 其他app要用这个http接口也比较方便,只是32445端口连个http 200都不返回粗暴了点.
