Perl HTTP请求content（）问题

Question

I want to put a file (file.img) as a POST data content, so if the file is in the same folder as the script, is $req->content(file.img); valid ?

Cheers

This seems to be something that you could easily test for yourself rather than asking us. What happened when you tried it?

(I'm going to assume that $req is an HTTP::Request object - I don't know why you wouldn't include that information in your question).

In short, no, it's not valid. And it's not valid for a number of reasons.

It's not valid because file.img would be interpreted as the bareword file concatenated with the bareword img - which would give the string fileimg .

It's not valid because use strict makes barewords illegal, so if you're using use strict (and you really should be) your code won't even compile.

It's not valid because HTTP::Request::content expects a sequence of bytes. So even if you didn't use use strict all this code would do would be to add the string fileimg to the request body.

If you want to add the contents of the file to the body, then you need to open the file, read in the data and then pass that data to content .

This is all explained in the documentation for HTTP::Request .
