fetch（）发送小写标题键 [英] fetch() sends lower case header keys

问题描述

我正在编写一个用于Atom Electron的HTTP API库。它基于 fetch 。服务器不受我的控制，但是用PHP编写，我可以看到它以区分大小写的方式检查标题。

I'm writing an HTTP API library for use in Atom Electron. It is based on fetch. The server is outside of my control, but is written in PHP and I can see it checks headers in a case-sensitive fashion.

我的代码类似于：

const headers = new Headers();
headers.append('Authorization', `Bearer ${key}`);

const init = {
    method: 'GET',
    headers: headers 
} 

const req = new Request(baseUrl + '/items?format=json');
return fetch(req, init);

请求被 403 FORBIDDEN 拒绝错误。当我在Electron Newtork面板中查看请求时，请求标头已存在，但授权已成为授权。

The request is rejected with a 403 FORBIDDEN error. When I look at the request in the Electron Newtork panel, the request headers are present but Authorization has become authorization.

我知道 fetch（）只是遵循HTTP标准，但有一种简单的方法可以获得 fetch（）在我提供时发送标题？

I know fetch() is just following the HTTP Standard, but is there a simple way to get fetch() to send the headers as I supply them?

推荐答案

目前获取将 toLowercase（）所有标题。 （这里有一些讨论 https://github.com/whatwg/fetch/issues/304关于可选的禁用）。

Currently fetch will toLowercase() all headers. (there is some discussion here https://github.com/whatwg/fetch/issues/304 about optional disabling).

现在你可能需要使用 http://api.jquery.com/jquery.ajax/ ，带有标题选项。

For now you may need to use http://api.jquery.com/jquery.ajax/ with the header option.
