http_fetch options

[madtowng]

Hi everyone,

I am trying to work with an API that I can call successfully using getpostman.
The response I get is "failure
No service was requested. No customer ID. No password. "

Any help would be greatly appreciated.

Gregg

dim pfmxr as p
dim baseurl as c = "http://apidomain.com/scripts/open.dll?"

I believe you have wandered away from the Mobile/Browser forum and gotten lost.

Good morning Stan,

I actually need this for a desktop application. The goal is to retrieve lat/lon data from a provider other than google.
Once I get this part right, I should be able to use their other APIs as well.

Re: http_fetch options

Your post body is XML. You should not urlencode it and set the content type to urlencoded. You should send it as-is and use a content type of either tex/xml or application/xml. You should be able to find out what exactly is expected in the API documentation.

Hi Lenny,

I appreciate your response.
My overabundance of failed efforts suggest I don't understand the http_fetch function as well as I should, and I am sure its the parameters I don't understand.

Example: http://host.serviceprovider.com/scri...dservice&xml=( your xml goes here... )

I can handle the url and the page from the above example, but would you be kind enough to show me how to code the items to the right of the "?" ?

Re: http_fetch options

(disclaimer:i am not an expert in xml) most often the xml document needs a paired descriptors and the content.
for example and xml request statement will be
<user>gandhi</user>,<password>some_password</password>
the program will know it is xml, and the coding is UTF-8 since it is the standard, also i believe that urlencoded is not needed since it is also standard in xml content ( not 100% sure)
what is important, the tags are not predefined so you can use any tags ( you should supply what the service provider wants and pair should match exactly.)
for example
<Response>....</response> is not correct as opposed to <Response>............</Response>
so in your example
http://host.serviceprovider.com/scri...dservice&xml=<name>gandhi</name>&<age>67</age>
something like this
that xml should be in the http_fetch settings, body as "<name>gandhi</name>&<age>67</age>"
(you may not need the '&' so look at their example to keep or skip)

edit:
i just looked at your first post, ( please disregard the line above) it is assumed this is what they are expecting
settings.body=urlencode(myxml)
settings.query_string="<country>USA</country>,<region>NY</region>,<city>new york</city>,<street>33 east end ave</street>"

this is my guess. since i did not want to reach out apidomain.com most often i encounter unwanted notification so i did not.
it is my impression the http_fetch.body contains what is the query string. not the query string itself in the settings. you can play with these and see if it works.

edit2: i am sure you can use http_post also with that url
the body will contain the geo_code_address in the form of string.

Re: http_fetch options

hi Gandhi,

I have tried http_post as well as http_fetch, and constantly get
results that say I did not choose a service, or the newest response shown below,
using this code to setup http_fetch.

As another option, I have been posting generic domain info because the other company considers this
proprietary. I can be more frank with the code if I'm working one on one.

pfmxr.body=""
pfmxr.header=""
pfmxr.query_string=""
pfmxr.host="apidomain.com"
pfmxr.method="POST"
pfmxr.page="/scripts/open.dll"
pfmxr.ssl_on = .f.
pfmxr.ssl_validatecert = .f.
pfmxr.header = "Content-Type: text/xml"

Re: http_fetch options

the request header says invalid verb
so the request needs to be in their list.
they are looking for the approved verbs.
will you be able to address that?

Re: http_fetch options

you don'e need to post all the information
can you post the domain name. as long as that is not virus infected site i can take a look at their documentation and see what they want.

edit: i omitted the 'not' and conveyed wrong message.

i don't see any string in the body, is that intentional?
and that is the error?

Re: http_fetch options

The only part I can think of would be

pfmxr.query_string= "service=geocode_address&xml="+myxml

which sets up pfmxr.query_string.

Re: http_fetch options

as far as i know you don't need "service=geocode_address&xml="+
your xml or absence of it is throwing the error.

Re: http_fetch options

what does your myxml say?

[madtowng]

Re: http_fetch options

myxml = <<%txt%
<?xml version="1.0" encoding="ISO-8859-1"?>

Re: http_fetch options

i am just guessing this will work, would you please check this out

dim settings as p
settingss.host = "apidomain.com/dtd/geocode_address.dtd"
setting.method = "POST"
settings.body= "<address>1231stStreetN</address><city>Minneapolis</city><state>MN</state><zip>55417</zip>"
settings.header = "<cid>customer_id</cid><pw>password</pw>"

dim response as p
response = http_fetch(settings)
show_var(response.body)
