MATLAB: Webread with comma in url

commahttpMATLABurlwebread

how can I use webread with comma in URL: e.g. my call: > url = 'page.html?q=1,2,3'; resp = webread(url);

Using webread this encodes to : page.html?q=1%2c2%2c3 and the server I'm calling returns an error (I have no control over that service and cannot change its API). There is much information about URI encoding, for example here: http://stackoverflow.com/questions/2366260/whats-valid-and-whats-not-in-a-uri-query But it doesn't help with Matlab's webread. Do you know what I need to do so that it passes a comma ","?

That's because those things after the '?' are not really part of the URI, but are query parameters. webread separate these from the base URI. You just specify these query parameters after the base URI as pairs of parameter name and parameter value. In your example:

webread('http://somwhere.com/page.html', 'q', [1 2 3])

MATLAB: Webwrite not send to right address

I'm hardly an expert but it looks like your web server is not configured properly. A ? at the end of the URL, not followed by anything, should not matter, and matlab is probably right to strip it from the URL.

? is part of the reserved character set for URIs. When it's not used for its normal purpose as it would appear with your server, it must be percent encoded. So try:

http://192.168.1.1/amp/query/BAND%3F

Note: ? is normally used to separate the URI from the POST arguments. So it is normally followed by SOMEARG=VALUE&SOMEOTHERARG=SOMEOTHERVALUE

MATLAB: What’s the MatLab WEBSAVE equivalent of this WGET command

Found my own answer to the single command question, need to use webwrite instead of webread.. very counterintuative!

data = webwrite(AUTHURL,'identity',USERNAME,'password',PASSWORD,'query',PAGEURL);

To use proxy: Home > Prefferences > Web
