Help saving results from function on local webserver...

[revel]

Hi,

I've a local application webserver which returns a result of trade data when the following command is entered in the browser address.

http://127.0.0.1:16239/req?GetHistory(kse:@ksu6,0,0,1D)

How do i store the result of the above command in rebol?

What should i modify from this code?
data: read http://127.0.0.1:16239/req?GetHistory(kse:@ksu6,0,0,1D)


Thanks

data contains the result of you read operation.

If you want to save it, just write it to your local drive

write %saved.txt data

should do it ...

Hi,

Thanks for the reply. I should have asked the question better and in this case store was the wrong word. What I was trying to say was that the above code does not return the trade results and thus incorrect.

in the browser, this is entered
http://127.0.0.1:16239/req?GetHistory(kse:@ksu6,0,0,1D)

which then returns

OK

in rebol, when entering in console
>> data: read http://127.0.0.1:16239/req?GetHistory(kse:@ksu6,0,0,1D)
== kse:@ksu6,0,0,1D
>> print data
Error: requires 4 arguments

It does not return the expected trade data from the running local server. I suspect it may be due to the ( ) in the url which causes the problem but I;m not quite sure how to solve that

Code:

data: read http://127.0.0.1:16239/req?GetHistory%28kse:@ksu6,0,0,1D%29

You just need to escape the parens with %28 and %29.

[revel]

Hi,

Not quite there yet. It seems that the @ sign is in the way.  Not sure whether the other remaining punctuations like : or , will affect as well.


>> data: read http://127.0.0.1:16239/req?GetHistory%28kse:@ksu6,0,0,1D%29
** Access Error: Cannot connect to ksu6,0,0,1D
** Where: open-proto
** Near: data: read http://127.0.0.1:16239/req?GetHistory%28kse:@ksu6,0,0,1D%29
>>



This is what I tried, which from to-url gave the same escape %28 and %29 as you mentioned. However, it seems the @ and perhaps other punctuation are causing confusion.


>> weburl: to-url http://127.0.0.1:16239/req?GetHistory(kse:@ksu6,0,0,1D)
== http://127.0.0.1:16239/req?GetHistory%28kse:@ksu6,0,0,1D%29
>> read weburl
** Access Error: Cannot connect to ksu6,0,0,1D
** Where: open-proto
** Near: read weburl
>> print weburl
http://127.0.0.1:16239/req?GetHistory(kse:@ksu6,0,0,1D)

Just tried a simpler ticker symbol ie qqqq and it works

>> weburl: to-url "http://127.0.0.1:16239/req?GetHistory(qqqq,0,0,1D)"
== http://127.0.0.1:16239/req?GetHistory%28qqqq,0,0,1D%29
>> data: read weburl
== {OK
06/21/2005,37.83,38.01,37.70,37.85,90041500
06/22/2005,38.00,38.10,37.63,37.83,72538200
06/23/2005,37.89,38.18,37.33,37.37,1...
>> print data
OK
06/21/2005,37.83,38.01,37.70,37.85,90041500
06/22/2005,38.00,38.10,37.63,37.83,72538200
06/23/2005,37.89,38.18,37.33,37.37,114012800
06/24/2005,37.38,37.41,36.96,36.96,136221600
.
.
.
etc


so a simple ticker symbol like qqqq works fine, however the more complex ticker symbol kse:@ksu6 returns errors as mentioned above...

[Gord]

My guess is that the username, password and host site are not being transferred properly in the url.  I have seen a syntax similar to the following:

username:password@URL

and the full URL that you gave us seems to be missing the password after the colon and URL after the "@" sign, (although I guess the "ksu6" could be the URL with the 0,0,1D as additional parameters).  In this case the interpreter is trying to use "ksu6,0,0,1D" as the URL with no parameters.

[revel]

hi,

it would seem that there's probably some convention such as that which you mentioned or perhaps just email@domain.com which causes rebol interpreter to not pass the full string as is and instead attempts to interpret the @ sign.

the local webserver application has a few functions with defined parameters. there is no password required as a parameter in this case. at least with a simple ticker symbol like qqqq it works.

Is there a way to escape the @ character like for the ( ) . the to-url function will not convert the @ character as oftentimes that would be the desired behaviour.

Is there a generic way to handle this scenario of ticker symbols with "special" punctuations  in them? Another ticker symbol format has the # instead of the @.

[Gabriele]

I'm not sure if @ is allowed in URL paths. Anyway, a general solution is:

Code:

read [
    scheme: 'http
    host: 127.0.0.1
    port-id: 16239
    target: "/req?GetHistory(kse:@ksu6,0,0,1D)"
]

or maybe:

Code:

read [
    scheme: 'http
    host: 127.0.0.1
    port-id: 16239
    path: "/"
    target: "req?GetHistory(kse:@ksu6,0,0,1D)"
]

This way you bypass REBOL's URL parsing completely.

[revel]

Hi,

Yes it finally works. I removed the / in the target string. Other then that everything seems just fine. Thanks !

data: read [
[        scheme: 'http
[        host: 127.0.0.1
[        port-id: 16239
[        target: "req?GetHistory(kse:@ksu6,0,0,1D)"
[    ]
connecting to: 127.0.0.1
