Angularjs 带:id的$http get
我正在尝试使用$http服务获取以下url路径 假设我有一根绳子 “/api/users/:id/fullinfo” ,id为5,如何获取此字符串的以下格式: “/api/users/5/fullinfo” ,通过$http.get()方法或$resourceAPI。Code 将此服务包括在您的应用程序中:Angularjs 带:id的$http get,angularjs,Angularjs,我正在尝试使用$http服务获取以下url路径 假设我有一根绳子 “/api/users/:id/fullinfo” ,id为5,如何获取此字符串的以下格式: “/api/users/5/fullinfo” ,通过$http.get()方法或$resourceAPI。Code 将此服务包括在您的应用程序中: app.service( "httpi", function( $http ) { return( httpProxy );

用法
在包含并注入它之后,您应该能够执行以下操作
httpi({
method: "post",
url: "/sample/:id",
data: {
id: "1"
}
});
它将调用带有POST的“/sample/1”,并且不再有数据

运行示例:我想你说的是,你的应用程序中有一个GET API端点,它响应动态路由
'/API/users/:id/fullinfo'
,你正在试图弄清楚如何使用$http
提供程序发出GET请求,对吗?如果是这种情况,则可以执行以下操作:
// create a service to manage the users resource
app.factory('UsersService', ['$http', function($http) {
function getById(id) {
var requestUrl = '/api/users/' + id + '/fullinfo';
return $http.get(requestUrl).then(function(resp) {
return resp.data;
}, function(err) {
// handle request error generically
});
}
return {
getById: getById
};
}]);
// consume the service in a controller like so:
app.controller('YourController', ['$scope', 'UsersService', function($scope, UsersService) {
var userId = 5; // you might also get this value from state params or some other dynamic way
UsersService.getById(userId).then(function(userInfo) {
$scope.userInfo = userInfo;
});
}]);
您应该能够使用
$interpolate
var getPath = '/api/users/{{id}}/fullinfo';
$scope.id= '5';
$interpolate(getPath)($scope);
或者,您也可以执行以下操作:
var path = '/api/users/' + id + '/fullinfo';
但是插值更好
$interpolate
