带有飞行前请求的 Angularjs $q.all 在 OPTIONS 请求后解析

Question

我有多个删除请求，前面有一个 OPTIONS 飞行前请求。但是在OPTIONS 请求之后，控件进入$q.all 的then。这是我的代码：

companyMasterC.confirmDelete = function(ev, text) {
     simpleDialog.verifyDelete(ev, text).then(function() {
         companyMasterC.deletePromise = companyMasterC.deleteSelected().then(function(response) {
              companyMasterC.getCompanies();
          }, function(error) {
                 console.log(error);
          });
     });
};

companyMasterC.deleteSelected = function(){
   var promises = companyMasterC.selectedRows.map(function(selectedRow) {
       return company.delete({id:selectedRow.id});
   });
   return $q.all(promises);
};

下面是“网络”选项卡中发生的情况：首先，执行OPTIONS 请求，然后执行GET 请求companyMasterC.getCompanies(); 当DELETE 请求被执行时应该执行。并且在GET请求DELETE请求被执行之后。

改变

return company.delete({id:selectedRow.id});

到

return company.delete({id:selectedRow.id}).$promise;

修改代码：

companyMasterC.confirmDelete = function(ev, text) {
     simpleDialog.verifyDelete(ev, text).then(function() {
         companyMasterC.deletePromise = companyMasterC.deleteSelected().then(function(response) {
              companyMasterC.getCompanies();
          }, function(error) {
                 console.log(error);
          });
     });
};

companyMasterC.deleteSelected = function(){
   var promises = companyMasterC.selectedRows.map(function(selectedRow) {
       return company.delete({id:selectedRow.id}).$promise;
   });
   return $q.all(promises);
};
