c# - Microsoft graph API how to create a bearer msal token -


trying authenticate, application basic console app, (not user) , access token right scopes. manage token without right scopes. i'm not sure if able this, missing?

static async task<string> getmsaltoken()         {             const string clientid = "xxxx234a3-7b9f-42341c-86df-3d2349861";             const string clientsecret = "wx324xxxxxxxxxxxxx";             var scopes = new list<string>() { "https://graph.microsoft.com/.default" };              var clientcredential = new microsoft.identity.client.clientcredential(clientsecret);             var redirecturi = "msalxxxx234a3-7b9f-42341c-86df-3d2349861://auth";              var clientapplication = new microsoft.identity.client.confidentialclientapplication(clientid, redirecturi, clientcredential, null, null);             var authenticationresult = await clientapplication.acquiretokenforclientasync(scopes);              return authenticationresult.accesstoken;         }

you using client credential authentication using application permissions in azure ad v2.0 endpoint , value passed scope parameter in request should resource identifier (application id uri) of resource want, affixed .default suffix. example ,the microsoft graph , value https://graph.microsoft.com/.default.

with client credential flow , application uses organization's data, not specific user. in such case, "administrator consent" (admin consent) used in azure ad, , consent must done administrator in organization. when use administrator consent, have go https://login.microsoftonline.com/{tenant name}/adminconsent?client_id={application id}&state={some state data}&redirect_uri={redirect uri}using web browser.

after admin consent , acquiring token microsoft graph using client credential flow , if decode access token using online tool , find application permissions listed in roles claim . please confirm have done admin consent application permissions .

here is tutorial using client credentials flow azure ad v2.0 endpoint.

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 ...
