为什么Chrome在验证之前调用自动完成的url？ [英] Why is Chrome calling the autocompleted url before validation?

问题描述

我在我的网站上使用API​​发送电子邮件给用户，同时在测试我的电话时，我注意到我收到了两次电子邮件。

看起来像localhost / api / sendEmail，至少在Chrome上，当我在本地主机上时，我开始输入/ ap网址会自动完成。

我可以在Fiddler上看到Chrome（我想那就是他）实际上是在我按Enter之前调用它，以便发送邮件，并且当按Enter键时当然是第二次发送。

这不是问题，因为它不会被最终用户直接调用，但我只是想知道什么是这个第一个电话的目的？ Chrome是否预先调用页面以加快载入速度？它会在不同的情况下造成问题吗？是否可以阻止Chrome的行为？

同样，这不是一个问题，但我只是想知道。

prefetch 功能，假设您执行了自动完成的URL，该功能可以更快地加载页面。

您可以在 Google Chrome 中停用此选项：

 设置>高级设置>隐私：（取消选中）预取资源.. 
  

I'm using an API on my website to send emails to the users and while testing my call I noticed I was receiving the email twice.

So the url looks like "localhost/api/sendEmail" and, at least on Chrome, when I'm on localhost and I start typing "/ap" the url is automatically completed.

And I can see on Fiddler that Chrome (well I think that's him) is actually calling it before I press Enter so the mail is sent, and when I press Enter it is of course sent a second time.

This is not a problem since it won't be directly callable by the end-user, but I was just wondering what is the purpose of this first call ? Is Chrome pre-calling the page to make it faster to load ? Can it cause problems in different situations? Can one prevent Chrome from behaving like this?

Again, not a problem at all, but I'm just wondering.

解决方案

This is Google's prefetch feature, which loads the page quicker, assuming you execute the auto-completed URL.

You can disable this option in Google Chrome:

Settings > Advanced Settings > Privacy: (uncheck) Prefetch resources..
