英文:
Data to pass in AngularJS http data field
问题
我有这段HTML代码：
<div class="row " style="margin-left:75pt;"><div class="dropdown"><label class="text-center" style="margin-top:10pt;font-size:14pt;"> Deals on</label> <button data-toggle="dropdown" class=" btn dropdown-toggle dropdown-menu-hover-color text-center" style="padding:0px 0px;background-color:white;" href="#"><label style="font-size:14pt; color: #191970;" >{{currentCategory}}</label> <b class="caret"></b></button><ul class="dropdown-menu submenu-hover-color" style="margin:0;"><li><a href="#" id="{{page.category_id}}" ng-click="changeCategory(page.category_id);" ng-repeat="page in dropdownCategoryList" ng-model="category_id">{{page.category_name}}</a></li></ul></div></div>
以及AngularJS控制器中的代码：
$scope.changeCategory = function(category_id) {$window.alert(category_id);$http({method : 'POST',url : '/changeCategory',data : category_id,headers : { 'Content-Type': 'application/x-www-form-urlencoded' }// 设置头部，以便AngularJS将信息作为表单数据传递（而不是请求负载）}).success(function(data, status, headers, config) {}).error(function(data, status, headers, config) {$scope.status = status;$window.alert("error")});}
我想在Golang后端中访问AngularJS控制器函数中的category_id参数，那么我应该在http的data字段中传递什么？
提前感谢。
英文:
I have this html
<div class="row " style="margin-left:75pt;"><div class="dropdown"><label class="text-center" style="margin-top:10pt;font-size:14pt;"> Deals on</label>&nbsp;<button data-toggle="dropdown" class=" btn dropdown-toggle dropdown-menu-hover-color text-center" style="padding:0px 0px;background-color:white;" href="#"><label style="font-size:14pt; color: #191970;" >{{currentCategory}}</label>&nbsp;<b class="caret"></b></button><ul class="dropdown-menu submenu-hover-color" style="margin:0;"><li><a href="#" id="{{page.category_id}}" ng-click="changeCategory(page.category_id);" ng-repeat="page in dropdownCategoryList" ng-model="category_id">{{page.category_name}}</a></li></ul></div></div>
And this code in Angularjs controller.
$scope.changeCategory = function(category_id) {$window.alert(category_id);$http({method : 'POST',url : '/changeCategory',data : category_id,headers : { 'Content-Type': 'application/x-www-form-urlencoded' }// set the headers so angular passing info as form data (not request payload)}).success(function(data, status, headers, config) {}).error(function(data, status, headers, config) {$scope.status = status;$window.alert("error")});}
I want to access the category_id parameter of the controller function in AngularJS in Golang at backend,so what should i pass in http's data field.
Thanks in advance

得分: 1
data是一个键值对映射（实质上是请求参数）。
data: {'category_id': category_id}
然后你的POST请求应该有一个名为"category_id"的参数。
关于在Go中处理JSON的问题，可以参考以下链接：

英文:
data is a mapping of key/values (requests params essentially)
data: { 'category_id': category_id }
Then your POST should have a param named "category_id"
and check this post about handling JSON in go
