如何将cURL详细输出通过管道发送到日志记录模块？

Question

Does anyone know how or if it's possible to redirect cURL verbose output to the logging module? Right now the verbose output is all going to stdout, but I'd like to pipe it to logging.debug which is being saved to a file.

Note that I don't want to pipe all console output to logging. Also, I do have a string buffer to capture the pycurl.WRITEFUNCTION however that doesn't seem to capture the VERBOSE output.

current code:

logging.debug('starting setopt_put for url: %s',api_url)
self._podium_curl_setopt_base(api_url.url + api_args)
self._podium_curl.setopt(pycurl.HTTPGET, 1)
self._podium_curl.setopt(pycurl.WRITEFUNCTION, self._string_buffer.write)
self._podium_curl.setopt(pycurl.VERBOSE, True)
self._podium_curl.perform()
logging.info(_string_buffer.getvalue())

Thanks!

curl has a DEBUGFUNCTION callback option that works in a similar way to the WRITEFUNCTION option, except that it gets called with the VERBOSE output instead of the response body.

The official documentation has reference information as well as a short example, which you should be able to adapt to your needs:

def test(debug_type, debug_msg):
    print "debug(%d): %s" % (debug_type, debug_msg)

c = pycurl.Curl()
c.setopt(pycurl.URL, "http://curl.haxx.se/")
c.setopt(pycurl.VERBOSE, 1)
c.setopt(pycurl.DEBUGFUNCTION, test)
c.perform()
