How to access output from Node.js' request module -


Several tutorials that request and cheerio In these tutorials, they send the output to the console or send the DOM to the file as an example with fs . 

  request (link, function, resp, html) {if (return) return console.error (err) var $ = cheerio.load (html), img = $ ('# img_wrapper' ). Data ('src'); Console.log (img);}). Pipe (fs.createWriteStream ('img_link.txt'));   
 But what if I want to process the output during script execution? How can I use the output or send it to the call function? I can definitely load  img_link.txt  and get information from there, but it will be expensive and will not make sense.   
 
 
 You can wrap a request in a function that  html   
  function (link, callback) {request (link, work (error, im, body) {callback (mistake, body);}); });   
 Then assign it to  export  and use it in any other module.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
