street2coordinates POST method

[Lance Crumbliss]

Can someone tell me the format the body needs to be in when sending a batch of addresses to geocode using POST?  I've tried:

('400 W BACHERT ST, LAFAYETTE, LA'

,'100 GIRARD PARK CL, LAFAYETTE, LA'

,'200 MCKINLEY ST, LAFAYETTE, LA'

,'1525 N UNIVERSITY AV, LAFAYETTE, LA'

,'6002 JOHNSTON ST, LAFAYETTE, LA'

,'1700 N UNIVERSITY AV, LAFAYETTE, LA'

,'4404 JOHNSTON ST, LAFAYETTE, LA'

,'1251 COOLIDGE ST, LAFAYETTE, LA'

,'1300 W UNIVERSITY AV, LAFAYETTE, LA')

and

'400 W BACHERT ST, LAFAYETTE, LA'

,'100 GIRARD PARK CL, LAFAYETTE, LA'

,'200 MCKINLEY ST, LAFAYETTE, LA'

,'1525 N UNIVERSITY AV, LAFAYETTE, LA'

,'6002 JOHNSTON ST, LAFAYETTE, LA'

,'1700 N UNIVERSITY AV, LAFAYETTE, LA'

,'4404 JOHNSTON ST, LAFAYETTE, LA'

,'1251 COOLIDGE ST, LAFAYETTE, LA'

,'1300 W UNIVERSITY AV, LAFAYETTE, LA'

and

('400 W BACHERT ST, LAFAYETTE, LA'

'100 GIRARD PARK CL, LAFAYETTE, LA'

'200 MCKINLEY ST, LAFAYETTE, LA'

'1525 N UNIVERSITY AV, LAFAYETTE, LA'

'6002 JOHNSTON ST, LAFAYETTE, LA'

'1700 N UNIVERSITY AV, LAFAYETTE, LA'

'4404 JOHNSTON ST, LAFAYETTE, LA'

'1251 COOLIDGE ST, LAFAYETTE, LA'

'1300 W UNIVERSITY AV, LAFAYETTE, LA')

and

 

'400 W BACHERT ST, LAFAYETTE, LA'

'100 GIRARD PARK CL, LAFAYETTE, LA'

'200 MCKINLEY ST, LAFAYETTE, LA'

'1525 N UNIVERSITY AV, LAFAYETTE, LA'

'6002 JOHNSTON ST, LAFAYETTE, LA'

'1700 N UNIVERSITY AV, LAFAYETTE, LA'

'4404 JOHNSTON ST, LAFAYETTE, LA'

'1251 COOLIDGE ST, LAFAYETTE, LA'

'1300 W UNIVERSITY AV, LAFAYETTE, LA'

but all that happens is returned is basically an echo:

{

  "'400 W BACHERT ST, LAFAYETTE, LA'\r\n'100 GIRARD PARK CL, LAFAYETTE, LA'\r\n'200 MCKINLEY ST, LAFAYETTE, LA'\r\n'1525 N UNIVERSITY AV, LAFAYETTE, LA'\r\n'6002 JOHNSTON ST, LAFAYETTE, LA'\r\n'1700 N UNIVERSITY AV, LAFAYETTE, LA'\r\n'4404 JOHNSTON ST, LAFAYETTE, LA'\r\n'1251 COOLIDGE ST, LAFAYETTE, LA'\r\n'1300 W UNIVERSITY AV, LAFAYETTE, LA'": null

}

Sorry about that Lance! You actually need to use JSON-style arrays, just like the first example but with square brackets instead of round ones. I've updated the docs to give a better description:

http://www.datasciencetoolkit.org/developerdocs#street2coordinates

and here's how you do it with curl from the command line:

curl -X POST --data '["2543 Graystone Place, Simi Valley, CA 93065", "400 Duboce Ave, San Francisco, CA 94114"]' 'http://www.datasciencetoolkit.org/street2coordinates'

Does that help?

cheers,

           Pete

that's it!  i thought i had tried it previously, but i think i was using single quotes instead of double quotes.  Thanks!

I know this isn't strictly related to DSTK, but it's related to using it. How can I take address data from a file--I have about 128k records--and pass them to the body of the request?

Thanks!

Something like this?

while read a; do curl -X POST --data '[$a]' 'http://www.datasciencetoolkit.org/street2coordinates'; done < addresses.txt

Hi Sophia,

Thanks for the response! I ended up using the following.

curl -o st2coord.json -X POST --data "[`cat addressarray.txt`]" 'http://www.datasciencetoolkit.org/street2coordinates'

That worked on a small sample of addresses. However, with my full set, it doesn't work.

-bash: /usr/bin/curl: Argument list too long

I guess I'll have to parse the list an iterate over the pieces.

Thanks,

Jay

It sounds like you're close, I'd recommend trying curl's file options for data:

http://curl.haxx.se/docs/manpage.html

"If you start the data with the letter @, the rest should be a file name to read the data from, or - if you want curl to read the data from stdin. Multiple files can also be specified. Posting data from a file named 'foobar' would thus be done with --data @foobar. When --data is told to read from a file like that, carriage returns and newlines will be stripped out."

Because you need to add the square brackets, you might want to pipe it in and use stdin, or just alter the file itself to add the brackets.
