emacs的url如何处理身份验证? [英] How does emacs url package handle authentication?
问题描述
(defun login-show-posts()
)
(let((url-request-methodGET)
(url-request-extra-headers'((Content-Type。application / xml)))
(url-retrievehttp:// localhost:3000 / essay / 1.xml
(lambda(status)
(switch-to-buffer(current-buffer))
))))
如果例如,用户和pass是admin:admin?
我的印象是, url.el
主要用于交互式操作,即您未经授权进行呼叫,服务器将使用403需要授权(正确代码?)状态进行响应,并且 url.el
会向用户查询用户名和密码。
您可以在查看我的代码http://github.com/hdurer/fluiddb .el 我尝试以编程方式进行操作。
基本上,我自己创建了HTTP authorzation标头(base64编码正确格式化的字符串,并添加了正确的标题到 url-request-extra-headers
)。
然后在第二步中,我需要向 url-http-handle-authentication
添加建议,以便不要向用户询问传递的凭据是否为可以接受。
这感觉很像强奸 url.el
,但它适用于我,是我唯一的办法可以使它工作。
你的代码看起来像这样:
(defvar xyz-user-nameadmin)
(defvar xyz-passwordadmin)
(defvar xyz-块授权nil
标记是否阻止url.el的通常的交互授权过程)
(defadvice url-http-handle-authentication(around xyz-fix)
除非xyz-block-authorization
ad-do-it))
(ad-activate'url-http-handle-authentication)
(defun login-
(交互式)
(let((xyz-block-authorization t))
(url-request-methodGET)
(url-request-额外标题
`((内容类型) application / xml)
(授权,(concatBasic
(base64-encode-string
(concat xyz-user-name:xyz-password)) ))))
(url-retrievehttp:// localhost:3000 / essay / 1.xml
(lambda(status)
(switch-to-buffer缓冲区))
))))
I have not seen a really good example on the web. How can I add authentication to a request like this:
(defun login-show-posts ()
(interactive)
(let ((url-request-method "GET")
(url-request-extra-headers '(("Content-Type" . "application/xml"))))
(url-retrieve "http://localhost:3000/essay/1.xml"
(lambda (status)
(switch-to-buffer (current-buffer))
))))
if for example, the user and pass is admin:admin?
I got the impression that url.el
was designed mostly for interactive operations, i.e. you do a call without authorisation, the server responds with a 403 "authorization needed" (correct code?) status and url.el
will query the user for user name and password.
You can have a look at my code on http://github.com/hdurer/fluiddb.el where I try to do things programmatically.
Basically, I create the HTTP authorzation header myself (base64 encoding the correctly formatted string and adding the correct header to url-request-extra-headers
).
Then in a second step I need to add advice to url-http-handle-authentication
so that it won't ask the user should the passed credentials not be acceptable.
This feels a lot like raping url.el
but it works for me and is the only way I could make it work.
Your code would thus look something like this:
(defvar xyz-user-name "admin")
(defvar xyz-password "admin")
(defvar xyz-block-authorisation nil
"Flag whether to block url.el's usual interactive authorisation procedure")
(defadvice url-http-handle-authentication (around xyz-fix)
(unless xyz-block-authorisation
ad-do-it))
(ad-activate 'url-http-handle-authentication)
(defun login-show-posts ()
(interactive)
(let ((xyz-block-authorisation t)
(url-request-method "GET")
(url-request-extra-headers
`(("Content-Type" . "application/xml")
("Authorization" . ,(concat "Basic "
(base64-encode-string
(concat xyz-user-name ":" xyz-password)))))))
(url-retrieve "http://localhost:3000/essay/1.xml"
(lambda (status)
(switch-to-buffer (current-buffer))
))))
