chrome 发送额外请求怎么办? [英] What to do with chrome sending extra requests?

问题描述

谷歌浏览器发送多个请求来获取页面，这显然不是错误，而是一项功能.而我们作为开发人员只需要处理它.

Google chrome sends multiple requests to fetch a page, and that's -apparently- not a bug, but a feature. And we as developers just have to deal with it.

就我能在五分钟内挖掘出来的内容而言，chrome 这样做只是为了让浏览速度更快，所以如果一个连接丢失，第二个将接管.

As far as I could dig out in five minutes, chrome does that just to make the surfing faster, so if one connection gets lost, the second will take over.

我想如果网站开发得很好，那么它的功能不会因此而中断，因为多个请求并不新鲜.

I guess if the website is well developed, then it's functionality won't break by this, because multiple requests are just not new.

但我不确定我是否已经考虑了此功能可能产生的所有情况.

But I'm just not sure if I have accounted for all the situations this feature can produce.

会不会有什么特殊情况?处理这些问题的最佳做法是什么?

Would there be any special situations? Any best practices to deal with them?

更新 1:现在我明白为什么我的银行页面在我用 chrome 打开页面时会抛出错误！它说:应该只打开浏览器的一个窗口."这就是他们对安全威胁的解决方案?！！

Update 1: Now I see why my bank's page throws an error when I open the page with chrome! It says: "Only one window of the browser should be open." That's their solution to security threats?!!

推荐答案

最好的办法是遵循标准的 Web 开发最佳实践:不要因 GET 调用而更改应用程序状态.

Your best bet is to follow standard web development best practises: don't change application state as a result of a GET call.

如果您担心，我建议您更新您的数据层单元测试，以便重复和复制 GET 调用.确保它们返回相同的数据.

If you're worried I recommend updating your data layer unit tests for GET calls to be duplicated & ensure they return the same data.

(顺便说一下，我在 Chrome 8.0.552.224 中没有看到这种行为，是不是很新?)

(I'm not seeing this behaviour with Chrome 8.0.552.224, by the way, is very new?)
