javascript - Chrome auto re-submits HTTP POST -


i have angular 1.x application doing http post api. if api takes longer 3-5 seconds process request, chrome submitting second request before first finished, causing api attempt process same request twice.

looking @ chrome dev tools, shows 1 request wireshark shows 2 http post requests same endpoint.

i've far been unable find documentation on behavior.

has else ran or found information how control it?

edit add code sample

html ng-click

<span><i class="fa fa-refresh" ng-click="resubmit(transaction.transid)"></i></span>

angular controller function

$scope.resubmit = function(transid) {         remediationservice.resubmit(transid).then(function(data) {             init();         });     };

angular service function

self.resubmit = function(id) {         return $http.post(api + '/remediation/resubmit/', {             transid: id         });     };

currently using test handler server side using hapijs in node cause issue forcing 10 second delay.

resubmit = async function(request, reply) {     console.log('test');     settimeout(function(){         reply({message:"success"})     }, 10000) }

after of above code executed, here see:

  1. chrome network tab in dev tools shows 2 requests, , http options request successful http 200 , single http post expected payload containing transaction id
  2. console log "test" twice
  3. wireshark shows http options, , 2 http post requests.
  4. after 10 seconds up, single http post request in chrome shows successful success message.

edit 2 - cors handling

this have in place handle cors , options preflight request:

server.route({         method: 'options',         path: '/{p*}',         config: {             handler: function(request, reply) {                 var response = reply();                 response.headers['access-control-allow-headers'] = 'content-type, authorization';                 response.headers['access-control-allow-methods'] = 'get, post, put, delete, options';                 return response;             },             cors: true         }     });

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 ...
