Monit检查URL跟随重定向

Question

我希望使用monit来监视我的网站。我希望它把它作为一个外部用户对待它，所以正在测试的网址，但它似乎不遵循重定向。内容检查正在重定向的html上执行。

#request works:
if failed url http://www.sharelatex.com/blog/posts/future.html content == "301"

#request fails
if failed url http://www.sharelatex.com/blog/posts/future.html content == "actual content"

找出如何让网址检查跟随30X将是很好的。

Answer 1

尽管我在monit手册页中没有看到一个选项使它遵循重定向，但我认为通过显式测试重定向的元素。首先测试重定向头，然后测试目标页面的内容，从而实现相同的目标。

(这是响应，包括从请求重定向到sharelatex )

HTTP/1.1 301 Moved Permanently       <---- response code here
Server: nginx/0.7.65
Date: Tue, 20 Mar 2012 22:04:48 GMT
Content-Type: text/html
Content-Length: 185
Connection: keep-alive
Location: https://www.sharelatex.com/blog/posts/future.html   <---- target location here

我会用下面这样的东西；

check host www.sharelatex.com with address www.sharelatex.com
IF FAILED URL http://www.sharelatex.com/blog/posts/future.html content == "301 Moved Permanently" 
    then alert
IF FAILED URL http://www.sharelatex.com/blog/posts/future.html content == "Location: https://www.sharelatex.com/blog/posts/future.html"
    then alert
IF FAILED URL https://www.sharelatex.com/blog/posts/future.html content == "ShareLaTeX"         
    then alert

所以打破它..。这两行检查HTTP://页面重定向是否正确，并检查它是否为重定向提供了正确的目标。

check host www.sharelatex.com with address www.sharelatex.com
IF FAILED URL http://www.sharelatex.com/blog/posts/future.html content == "301 Moved Permanently" then alert
IF FAILED URL http://www.sharelatex.com/blog/posts/future.html content == "Location: https://www.sharelatex.com/blog/posts/future.html" then alert  

然后测试你是否被重定向到正确的地方，并得到一些内容.

然后，下面的行，有效地显式地执行重定向，并在https://www.sharelatex.com/blog/posts/future.html上测试HTTPS页面的内容

 IF FAILED URL https://www.sharelatex.com/blog/posts/future.html content == "ShareLaTeX" then alert   

我猜第一批命令每页会产生一堆(2倍)的请求，所以可能值得将它们组合在一起.
