Hi all,
If I'm sending single valued data over web, eg. a=111, b=222, c=333, then I can do http://.../xxx.cgi?a=111&b=222&c=333
How do I send array data, like A[1]=111, A[2]=222, A[3]=333 to a CGI script? I don't think I can do something like http://.../xxx.cgi?A[1]=111&A[2]=222&A[3]=333 Or, can I?
I have seen a same variable repeated, http://.../xxx.cgi?A=111&A=222&A=333 but that means the CGI script has to build the array.
If JSON is an option, it is pretty easy to do what you're after in javascript. For example, I've been working on a project using crypto.subtle in the browser. I generate a key and an IV with javascript, and it is easy to represent the arrays of bytes like you've specified. For example: I have an IV Uint8Array(16) that looks like this: Uint8Array(16) [ 147, 174, 163, 227, 241, 236, 204, 23, 159, 18, … ] As a string it looks like what you'd expect - iv.toString() shows: "147,174,163,227,241,236,204,23,159,18,218,74,177,105,214,153" Now what you're after with mapping in JSON (I've inserted line breaks): JSON.stringify(iv)) {"0":147,"1":174,"2":163,"3":227,"4":241,"5":236, "6":204,"7":23,"8":159,"9":18,"10":218, "11":74,"12":177,"13":105,"14":214,"15":153} Alternatively, you can get an unkeyed array using Array.from() and converting that to JSON: JSON.stringify(Array.from(iv)) "[147,174,163,227,241,236,204,23,159,18,218,74,177,105,214,153]" Any of that look useful?
