c# - How to get oauth2 token with the WWW API? -


i working on project requires oauth2 token communicate. backend gives me curl command, have no idea how put www form in unity because have no former experience http or json file. me access token? thanks. here how curl code looks like:

$ curl -v -u {client_id}:{client_secret} "https://api.domo.com/oauth/token?grant_type=client_credentials&scope={scope}"

and here example:

$ curl -v -u 441e307a-b2a1-4a99-8561-174e5b153fsa:f103fc453d08bdh049edc9a1913e3f5266447a06d1d2751258c89771fbcc8087 "https://api.domo.com/oauth/token?grant_type=client_credentials&scope=data%20user"

thank much!

to oauth2 token www api, use wwwform create form contains grant_type, client_id , client_secret. when make request, token should returned in json format. use unity's jsonutility convert string can obtain.

retrieving token:

[serializable] public class tokenclassname {     public string access_token; }  ienumerator getaccesstoken() {     var url = "http://yoururl.com";     var form = new wwwform();     form.addfield("grant_type", "client_credentials");     form.addfield("client_id", "login-secret");     form.addfield("client_secret", "secretpassword");      www www = new www(url, form);      //wait request complete     yield return www;      //and check errors     if (string.isnullorempty(www.error))     {         string resultcontent = www.text;         unityengine.debug.log(resultcontent);         tokenclassname json = jsonutility.fromjson<tokenclassname>(resultcontent);         unityengine.debug.log("token: " + json.access_token);     }     else     {         //something wrong!         unityengine.debug.log("www error: " + www.error);     } }

using token:

after receive token, stored in json.access_token variable. can use use make requests adding header of other www requests. header stored in dictionary this:

headers.add("authorization", "bearer " + token);

here full example making request received token:

ienumerator makerequestwithtoken(string token) {     var url = "http://yoururl.com";      dictionary<string, string> headers = new dictionary<string, string>();     headers.add("authorization", "bearer " + token);      wwwform formdata = new wwwform();     formdata.addfield("yourfield", "yourval");     formdata.addfield("yourfield", "yourval");      www www = new www(url, formdata.data, headers);     yield return www;      //and check errors     if (string.isnullorempty(www.error))     {         string resultcontent = www.text;         unityengine.debug.log(resultcontent);     }     else     {         //something wrong!         unityengine.debug.log("www error: " + www.error);     } }

unity uses unitywebrequest. if possible start using that. here example of retrieving oauth2 unitywebrequest.

note both functions coroutine functions , must started startcoroutine function startcoroutine(getaccesstoken()); , startcoroutine(makerequestwithtoken("yourtoken"));.

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 ...
