In the general case, this code would be very fragile. Servers can lie about content length; things can go wrong. You should attempt to try to read a certain number of times, possibly giving up after a series of consective reads that draw zero bytes, and/or return all that you have after a given amount of time.

update to Ilya's response: I should clarify my statement. Several years ago I had that sort of code running in a script, and I came to grief over the problem of content length. It didn't always correspond to what I received. I no longer have access to the code, so I can't go and look it up, but in a nutshell I ignored the content-length value, and just tried to read as much as I could in a certain time frame (45 seconds IIRC).

That said, I'm willing to believe that servers these days are much more reliable, and produce accurate values for content length... although I think I'll always mistrust them.

In reply to Re:x2 Reading RAW POST data by grinder
in thread How do I read POST data that is not encoded, and was submitted without a parameter name by c-era

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
