Authenticated Request In Google App Engine Using Fetch() Function: How To Provide The Information In The Header Of The Request?

I am trying to pass automatically, using Google App Engine, my password and ID to eBay, to this page: https://signin.ebay.com/ws/eBayISAPI.dll?SignIn&UsingSSL=1&pUserId=&a

Solution 1:

I'm not sure if this helps, but ebay has an API that would be simpler to use and incorporate. Check out http://developer.ebay.com/businessbenefits/aboutus/

Solution 2:

Looks like some of the quote-characters are the wrong kind -- reversed "smart quotes" rather than normal plain ordinary ASCII quote characters. Hard to say precisely from screenshots! The error screen you're showing (from GAE's SDK) shows the exact location of the error at the very bottom -- and you're showing it scrolled all the way to the very top, so it doesn't help.

In GAE like in any other use of Python quote is done via plain single and double quote characters: ' and " ; not via slanted, inverted, or "smart" quote characters, such as

`

(hard to clearly show the inverted single quote in SO except as a codeblock, since it's used to mark inline code;-) or ″, ”, “, and so forth. So check your code carefully to make sure you're using the normal, plain kinds of quotes!
