Re: QueryStrings

Hi Matt,

<snip>
I have climbed the mountain today to find out if there is any existing code
or an API that will simplify parsing HTTP QueryStrings from RPG. I am
processing data and one of the fields being sent to us is a URL. I need to
extract some information from that query string. Obviously, parsing a
query string is fairly easy until you start having URL encoded values
("%20" and the like). We need to convert those sorts of values before
putting them in the database.

I am not one that likes reinventing the wheel and I find it hard to believe
something is out there that I just haven't found. I suppose if there is
not such a tool, there soon will be, because I am going to have to tackle
this issue one way or another.
</snip>If you want to parse the query string into a DB file format then take a look at QtmhCvtDb.

This API takes the query string and populates a DS or character string with the values. You pass it the name of the file and it will populate your DS/string with the query string data in the format of the file. It does something similar to eval-corr in that it will take the query parameters and populate the file fields with the same. Essesntially, it converts the query parameter data to the appropriate DB field data format (packed, zoned, etc) and then put it at the correct offset within the string.

I used it a long time ago and used an extname DS to hold the result. It worked quite well.

Not sure how you are getting this query string so don't know if this will help you with URL encoding. It is certainly an option for getting the data into the correct DB format though.

Cheers, and good luck
