在验证墙后生成PDF [英] Generate PDF Behind Authentication Wall
问题描述
我试图使用WKHTMLTOPDF生成一个PDF，要求我先登录。在互联网上已经有一些，但我似乎无法得到我的工作。
I'm trying to generate a PDF using WKHTMLTOPDF that requires me to first log in. There's some on this on the internet already but I can't seem to get mine working. I'm in Terminal - nothing fancy.
我尝试过（其他很多东西）：
I've tried (among a whole lot of other stuff):
/usr/bin/wkhtmltopdf --post username=myusername --post password=mypassword "URL to Generate" test.pdf
/usr/bin/wkhtmltopdf --username myusername --password mypassword "URL to Generate" test.pdf
/usr/bin/wkhtmltopdf --cookie-jar my.jar --post username=myusername --post password=mypassword "URL to Generate Cookie For"
用户名和密码都是 id 以及表单上输入字段的名称。
username and password are both the id and the name of the input fields on the form. I am getting the my.jar file to show up, but nothing is written to it.
具体问题：
- 我应该在任何地方指定登录页面和/或表单操作吗？
- 在各种地方提到了--cookie-jar参数需要和其他）。如果有必要，它是如何工作的？我创建了my.jar文件，但是如何再次使用它？引用：

EDIT：
当然有人成功了吗？一个展示示例的好方法是，如果有人愿意在需要登录凭据的一些热门网站上工作，以消除潜在变量。
Surely someone has done this successfully? A good way to showcase an example might if someone is willing to get it to work on some popular website that requires login credentials to eliminate a potential variable.
推荐答案
我想我要登录的形式太复杂了。它是安全的，设置三个cookie，重定向两次，并发布用户名和密码之外的其他变量，其中一个需要一个cookie值（我甚至尝试连接的值到post变量，但没有运气）。这可能是一个非常罕见的问题 - 决不是WKHTMLTOPDF的错误。
I think the form I'm trying to log in to is too complex. It's secure, sets three cookies, redirects twice, and posts a number of other variables outside of the username and password, one of which requires a cookie value (I even tried concatenating the value into the post variable, but no luck). This is probably a pretty rare issue - by no means the fault of WKHTMLTOPDF.
我绕过使用CURL登录并将页面写入本地文件，然后运行WKHTMLTOPDF反对。
I wound up using CURL to log in and write the page to a local file, then ran WKHTMLTOPDF against that. Definitely a solid work around for anyone else having a similar issue.
编辑：CURL，如果感兴趣：
CURL, if interested:
curl_setopt($ch, CURLOPT_HEADER, 1); # Change to 1 to see WTF
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_URL, $loginUrl);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
