Security Check

+

This is a simple security test that attempts to make a request to the Questions API, + passing the security parameters you provide in the form below.

+

If the request is successful, a status code 200 will be returned in the box at the + bottom of the page, otherwise a status code 403 will be returned.

+

Information on security is available on the documentation site for + the Questions API.

+
+ +
+
+
+
+

Security Parameters

+ +
+
+
+ +
+
+
+ Unique id provided by Learnosity that allows the server to identify the + client and retrive its consumer_secret. +
+
+ + +
+
+
+ +
+
+
+ Must be the same as location.hostname, as the Learnosity Questions API is sending + that value to the server for authentication. +
+
+ + +
+
+
+ +
+
+
+ Current time in GMT/UTC.The server will check if the timestamp is within the allowed + time frame: 3h in this test. +
+
+ + +
+
+
+ +
+
+
The id of the student/user whose assets are to be requested.
+
+ + +
+
+
+ +
+
+
+ Secret key supplied by Learnosity, which must not be exposed + either by sending it to the browser or across the network. +
+
+
+
+
+

+ JS Beautifier
+---------------
+
+
+  Written by Einar Lielmanis, 
+      http://jsbeautifier.org/
+
+  Originally converted to javascript by Vital, 
+  "End braces on own line" added by Chris J. Shull, 
+
+  You are free to use this in any way you want, in case you find this useful or working for you.
+
+  Usage:
+    js_beautify(js_source_text);
+    js_beautify(js_source_text, options);
+
+  The options are:
+    indent_size (default 4)          — indentation size,
+    indent_char (default space)      — character to indent with,
+    preserve_newlines (default true) — whether existing line breaks should be preserved,
+    preserve_max_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk,
+
+    jslint_happy (default false) — if true, then jslint-stricter mode is enforced.
+
+            jslint_happy   !jslint_happy
+            ---------------------------------
+             function ()      function()
+
+    brace_style (default "collapse") - "collapse" | "expand" | "end-expand"
+            put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line.
+
+    e.g
+
+    js_beautify(js_source_text, {
+      'indent_size': 1,
+      'indent_char': '\t'
+    });
