Getting Image from API, then storing it as Azure Storage Blob (image error) -


so i'm trying this:

  1. get users ad using graph api in azure function (c# or node)
  2. for each user, photo, using graph api (in same azure function)
  3. with photo data, upload blob azure storage

now, have 1 , 2 working correctly. now, have no idea how convert image/jpeg string blob in azure storage. i've tried lot, researched lot it's been difficult.

i've tried use

blob.properties.contenttype = "image/jpeg" blob.uploadtext(imgstring);

but doesn't work.

so code looks this:

  1. i fresh oauth token azure (good 3600 sec)
  2. get /users ad graph api
  3. for each user, use /user//photo/$value resource, returns image/jpeg data.
  4. from data (a string?) try blob.uploadtext fails.

the way i'm getting image data graphapi using restsharp, this:

var client = new restclient("https://graph.microsoft.com/v1.0/users/" + email + "/photo/$value"); var request = new restrequest(method.get); request.addheader("cache-control", "no-cache"); request.addheader("authorization", "bearer " + token); request.addheader("content-type", "image/jpeg"); return client.execute(request);

so return irestresponse, contains this:

response.contenttype //to content type response.content // body (the image) blob.uploadtext(response.content);

and that's i'm trying do, doesn't work, file gets saved ok when open it, can't see image. think issue might encoding, i've tried setting different encoding types no luck.

take @ next picture. right, got image graph api using php, , set header image/jpeg, echo image data , that's it. works. on left, it's azure function javascript or c#, image , when try same (show in browser) different binary string , no picture on page (like if wasn't image data), looks if problem encoding. i'm saving binary data on blob file uploadtext it's not working.

encoding

any ideas?

any ideas?

please have use rawbytes blob content. works correctly on side.

blob.uploadfrombytearray(response.rawbytes,0,response.rawbytes.length-1);

the following test demo code 

var connectionstring = "storage connection string"; cloudstorageaccount storageaccount =  cloudstorageaccount.parse(connectionstring); cloudblobclient blobclient = storageaccount.createcloudblobclient(); cloudblobcontainer container =  blobclient.getcontainerreference("container"); container.createifnotexists(); cloudblockblob blob = container.getblockblobreference("test.jpeg");         blob.uploadfrombytearray(response.rawbytes,0,response.rawbytes.length-1);

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
