从 Emacs 访问 StackExchange API
我尝试从 Emacs 的 elisp 访问 StackExchange API：
(require 'url)
(require 'json)
(defvar url-http-end-of-headers)
(defun read-json ()
(interactive)
(with-current-buffer (url-retrieve-synchronously "http://api.stackoverflow.com/0.8/users/2386")
(goto-char url-http-end-of-headers)
(json-read)))
Mx read-json 导致以下错误：JSON readtable error。
我错过了什么吗？

M-x read-json results in the following error: JSON readtable error.
Am I missing anything?

这几乎肯定与 gzip 编码有关，原始服务器响应如下：
客户端似乎没有明确自愿支持 gzip（注意缺少 Accept-Encoding 标头），但服务器无论如何都会压缩响应。以下是运行代码时来自我的客户端的请求标头：
根据 HTTP 规范，服务器行为是可接受的：
如果您显式设置标头值，则会按预期返回响应：
This is almost certainly related to gzip encoding, the raw server response is as follows:
The client does not appear to be explicitly volunteering that it supports gzip (note the absence of the Accept-Encoding header), but the server is compressing the response anyways. Here are the request headers from my client when running your code:
The server behavior is acceptable according to the HTTP spec:
If you explicitly set the header value, the response is returned as expected:
