java - Selenium 2: Detect content type of link destinations -

-

I am using the Selenium2Java API to interact with web pages. My question is how can I find out the content type of link sites?

Actually, this is the background: before clicking on a link, I have to make sure that the response is an HTML file, if not, I have to handle it in another way. So, suppose that there is a download link for the PDF file. Instead of opening it in the browser, the contents of that URL should be read directly.

A target must have an application that automatically knows that the existing location is HTML, PDF, XML or whatever the appropriate parser to extract useful information from documents.

Updates

Added reward: This will provide me the best solution that allows me to get the content type of a given URL

As Yochan suggested, how to get content types without downloading content HTTP HEAD , and Selenium WebDrive does not seem to provide such functionality.

There is a java library which can do this, especially.

(The following code is Untested) 

  http client httpclient = new DefaultHttpClient (); Http head httphead = new HTTP head ("http: // foo / bar"); HttpResponse response = httpclient.execute (httphead); BasicHeader contenttypeheader = response.getFirstHeader ("content-type"); Println (contenttypeheader);   
 The project publishes, for this it is a good example in the documentation.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
