How to Add a file to Google Drive via Docs Add On using App Script? -

-

this question has answer here:

here scenario. i've created add-on google docs acts video toolbox.

a feature i'm trying add ability record video using built in web cam (using videojs-recorder) , link video within doc. i've got video part working, not sure how webm js blob converted google blob can create file on users google drive sharing , linking.

just figure out how might work i've done far without luck.

client side code

//event handler video recording finish    vidrecorder.on('finishrecord', function() {     // blob object contains recorded data     // can downloaded user, stored on server etc.     console.log('finished recording: ', vidrecorder.recordeddata);     google.script.run.withsuccesshandler(function(){         console.log("winning");     }).saveblob(vidrecorder.recordeddata); });

server side code

function saveblob(blob) {     logger.log("uploaded %s of type %s , size %s.",             blob.name,             blob.size,              blob.type); }

the errors seem related serialization of blob. exceptions aren't useful - , point minimized code.

edit: note there no form object involved here, hence no form post, , no fileupload objects, others have indicated this might duplicate, it's different in getting blob object , need save server.

thanks goes zig mandel , steve webster provided insight g+ discussion regarding this.

i pieced enough bits working.

client code

        vidrecorder.on('finishrecord', function()         {             // blob object contains recorded data             // can downloaded user, stored on server etc.             console.log('finished recording: ', vidrecorder.recordeddata.video);             var blob = vidrecorder.recordeddata.video;              var reader = new window.filereader();             reader.readasdataurl(blob);             reader.onloadend = function() {                 b64blob = reader.result;                  google.script.run.withsuccesshandler(function(state){                         console.log("winning: ", state);                  }).saveb64blob(b64blob);             };          });

server code

function saveb64blob(b64blob) {     var success = { success: false, url: null};     logger.log("got blob: %s", b64blob);     try {         var blob = datauritoblob(b64blob);         logger.log("gblob: %s", blob);         var file = driveapp.createfile(blob);         file.setsharing(driveapp.access.anyone_with_link, driveapp.permission.comment);         success = { success: true, url: file.geturl() };     } catch (error) {         logger.log("error: %s", error);     }     return success; }  function datauritoblob(datauri) {     // convert base64/urlencoded data component raw binary data held in string     var bytestring;     if (datauri.split(',')[0].indexof('base64') >= 0)         bytestring = utilities.base64decode(datauri.split(',')[1]);     else         bytestring = decodeuri(datauri.split(',')[1]);      // separate out mime component     var mimestring = datauri.split(',')[0].split(':')[1].split(';')[0];      return utilities.newblob(bytestring, mimestring, "video.webm"); }

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
