Incorrectly formatted returned values in mod URL, prevents course_get_contents WS to work

Inside a course create a couple of resources (type URL), the Name of the resource should contain characters like ": & . ../ ./ & < >" etc.. Enable "Mobile services": Plugins ► Web Services ► External services Create a Token: Click on Site administration ► Plugins ► Web services ► Manage tokens Click add, select user and service (Mobile Service) Next, you can do a CURL REST call simulating a WS client: You need to replace the courseid values . You also need to replace the wstoken and the URL of your moodle instance curl 'http://localhost/moodlebugs/webservice/rest/server.php?moodlewsrestformat=json' -H 'Pragma: no-cache' -H 'Origin: file://' -H 'Accept-Encoding: gzip,deflate,sdch' -H 'Accept-Language: es,en;q=0.8,de-DE;q=0.6,de;q=0.4' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1798.0 Safari/537.36' -H 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8' -H 'Accept: application/json, text/javascript, */*; q=0.01' -H 'Cache-Control: no-cache' -H 'Cookie: MoodleSession=f40pv08phpbc79boa0oh8h2r94' -H 'Connection: keep-alive' --data 'options%5B0%5D%5Bname%5D=&options%5B0%5D%5Bvalue%5D=&courseid=4&wsfunction=core_course_get_contents&wstoken=493d2e785f81515296cf09e05f1f8179' --compressed Confirm that: The result of that curl call list all contents and resources in the course, the filename attirubte of the URLs is correctly formatted, all the invalid characterse like : has ben removed, you can use http://jsonlint.com to format the output
