拒绝设置不安全的标题“连接” [英] Refused to set unsafe header "Connection"

问题描述

我正在开发针对Android和iOS平台的跨平台应用程序。我使用的是jQuery 1.9.1，Jquery Mobile 1.3.1和Phonegap 2.8.0。

I am working on a cross platform application that targets Android and iOS platforms. I am using jQuery 1.9.1, Jquery Mobile 1.3.1 and Phonegap 2.8.0.

我想发送一个ajax请求并设置请求标题Connection和Keep-Alive。在操作系统大于4.1的Android手机上（默认浏览器是Chrome），我收到一条错误，上面写着拒绝设置不安全的标题连接。

I want to send an ajax request and set the request headers "Connection" and "Keep-Alive". On Android Phones with OS greater than 4.1 (Whose default browser is Chrome) I get an error which says "Refused to set unsafe header "Connection"".

我可以在低端设备上甚至在iPhone上发送此类请求。

I am able to send such requests on lower end devices and even on iPhones.

任何人都可以帮助我。

Can Anyone Please help me out.

我必须在请求中设置这两个标头。

I have to set these 2 headers in the request.

提前致谢。

推荐答案

部分 4.6.2 列出了由用户代理并且不允许使用 setRequestHeader（）方法设置。 连接和 Keep-Alive 都在该列表中。

Section 4.6.2 of the W3C XMLHttpRequest Level 1 spec lists headers that "are controlled by the user agent" and not allowed to be set with the setRequestHeader() method. Both Connection and Keep-Alive are in that list.
