I have a little application that wants to send data to a Google API. This API requires an HTTP header to be set as follows:
Authorization: GoogleLogin auth=[value of auth token goes here] Unfortunately, I'm getting nothing but 400 Bad Requests. I suspect this is due to an unfeature of urllib2. Notably, although you can use urllib2.Request's add_header method to append a header, the documentation (http://docs.python.org/library/urllib2.html) says that: remember that a few standard headers (Content-Length, Content-Type and Host) are added when the Request is passed to urlopen() (or OpenerDirector.open()). And: Note that there cannot be more than one header with the same name, and later calls will overwrite previous calls in case the key collides. To put it another way, you cannot rely on Content-Type being correct because whatever you set it to explicitly, urllib2 will silently change it to something else which may be wrong, and there is no way to stop it. What happened to "explicit is better than implicit"? -- http://mail.python.org/mailman/listinfo/python-list
