uhttpd not handle cgi output properly

Reported by: dzuy@… Owned by: developers
Priority: high Milestone: Barrier Breaker 14.07
Component: packages Version: Trunk
Keywords: uhttpd Cc:


When executing a simple cgi script, my browser keeps telling me that it's a BIN file even though I specify it's a text/plain content type. Here is a real simple cgi script:


echo "Content-Type: text/plain"
echo ""
echo "foo"

The problem is with uhttpd-cgi.c line 477:

ensure(uh_http_send(cl, req, &hdr[hdroff], hdrlen - hdroff));

(hdrlen - hdroff) is 1 longer than the buffer being sent. Since the uh_http_send() function calculates the length of the buffer before sending it out, just call

ensure(uh_http_send(cl, req, &hdr[hdroff], -1));

should do it.

I cannot verify your problem, the provided example works as expected
without modifications to the httpd source.

Make sure your line endings are correct (\r\n vs. \n) and that there is
no trailing whitespace around.

A more clean way to specify the header is:

echo -en "Content-Type: text/plain\r\n\r\n"
echo "Content..."
