Doesn't work - I get the same error back:
blah, blah ... Your client has issued a malformed or illegal request.
That’s all we know
I've tried appending the data as you suggest. I've tried adding ?
deliberately to the URI. I've tried with and without #:headers.
#:version #1.0 and #1.1. #:method #GET vs #POST. Everything
produces the same error.
But perversely the result of (string-append
http://maps.googleapis.com/maps/api/geocode/json?;
http://maps.googleapis.com/maps/api/geocode/json form-data) works if I
paste it into a browser.

Re: [racket-users] http-sendrecv with Google geocode
Hi Sean, Even weirder when I tried this morning your string-append solution - which I had left in place - worked immediately with no changes from last night. The only thing different is I had closed DrRacket before going to bed and reopened it this morning. Maybe something was wonky in DrRacket? It had been running about ~14 hours yesterday at the point I started having trouble and I fought with it a couple more hours before quitting? But AFAICR, I've never seen that before. However, as you discovered also, passing the data as #:data doesn't work and now I'm interested in why. ISTM that the URI + #:data should be identical to the string-append with ? and #:method #GET. Also, Google recommends using POST if the data is sensitive, but I can't get POST to work even from a pure HTML form in a browser. So now I'm really curious as to what's going on.

I'm using http-sendrecv successfully with other web APIs - I just can't
figure out what I'm doing wrong with Google. Number and/or frequency of
requests is not an issue - I'm very far from the daily limit and many
minutes elapse between tests as I'm trying to figure out what's wrong.
The documentation is at
https://developers.google.com/maps/documentation/geocoding/#GeocodingRequests
Any clues to pierce the veil of stupidity would be appreciated.
Thanks,
George
