AngularJS将数据传递给$http。get请求

I have a function which does a http POST request. The code is specified below. This works fine.

我有一个处理http POST请求的函数。代码在下面指定。这是很好。

 $http({
   url: user.update_path, 
   method: "POST",
   data: {user_id: user.id, draft: true}
 });

I have another function for http GET and I want to send data to that request. But I don't have that option in get.

我有另一个http GET函数，我想把数据发送给那个请求。但是我没有这个选项。

 $http({
   url: user.details_path, 
   method: "GET",
   data: {user_id: user.id}
 });

The syntax for http.get is

http的语法。得到的是

get(url, config)

get(url、配置)

Can someone help me with this?

有人能帮我吗?

An HTTP GET request can't contain data to be posted to the server. However, you can add a query string to the request.

HTTP GET请求不能包含要发送到服务器的数据。但是，您可以向请求添加查询字符串。

angular.http provides an option for it called params.

角。http提供了一个名为params的选项。

$http({
    url: user.details_path, 
    method: "GET",
    params: {user_id: user.id}
 });

See: http://docs.angularjs.org/api/ng.$http#get and https://docs.angularjs.org/api/ng/service/$http#usage (shows the params param)

参见:http://docs.angularjs.org/api/ng $http#get和https://docs.angularjs.org/api/ng/service/$http#用法(显示params param)

You can pass params directly to $http.get() The following works fine

您可以直接将params传递给$http.get()，下面的工作很好。

$http.get(user.details_path, {
    params: { user_id: user.id }
});

#3

Starting from AngularJS v1.4.8, you can use get(url, config) as follows:

从AngularJS v1.4.8开始，您可以使用get(url, config)如下:

var data = {
 user_id:user.id
};

var config = {
 params: data,
 headers : {'Accept' : 'application/json'}
};

$http.get(user.details_path, config).then(function(response) {
   // process response here..
 }, function(response) {
});

Solution for those who are interested in sending params and headers in GET request

对于在GET请求中发送params和header感兴趣的人的解决方案

$http.get('https://www.your-website.com/api/users.json', {
        params:  {page: 1, limit: 100, sort: 'name', direction: 'desc'},
        headers: {'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
    }
)
.then(function(response) {
    // Request completed successfully
}, function(x) {
    // Request error
});

Complete service example will look like this

完整的服务示例如下所示

var mainApp = angular.module("mainApp", []);

mainApp.service('UserService', function($http, $q){

   this.getUsers = function(page = 1, limit = 100, sort = 'id', direction = 'desc') {

        var dfrd = $q.defer();
        $http.get('https://www.your-website.com/api/users.json', 
            {
                params:{page: page, limit: limit, sort: sort, direction: direction},
                headers: {Authorization: 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
            }
        )
        .then(function(response) {
            if ( response.data.success == true ) { 

            } else {

            }
        }, function(x) {

            dfrd.reject(true);
        });
        return dfrd.promise;
   }

});

You can even simply add the parameters to the end of the url:

您甚至可以简单地将参数添加到url的末尾:

$http.get('path/to/script.php?param=hello').success(function(data) {
    alert(data);
});

Paired with script.php:

搭配script.php:

<? var_dump($_GET); ?>

Resulting in the following javascript alert:

导致以下javascript警告:

array(1) {  
    ["param"]=>  
    string(4) "hello"
}

#6

For sending get request with parameter i use

对于发送带有参数的get请求，我使用

  $http.get('urlPartOne\\'+parameter+'\\urlPartTwo')

By this you can use your own url string

您可以使用自己的url字符串。

Here's a complete example of an HTTP GET request with parameters using angular.js in ASP.NET MVC:

这里有一个使用角度参数的HTTP GET请求的完整示例。js在ASP。NET MVC:

CONTROLLER:

控制器:

public class AngularController : Controller
{
    public JsonResult GetFullName(string name, string surname)
    {
        System.Diagnostics.Debugger.Break();
        return Json(new { fullName = String.Format("{0} {1}",name,surname) }, JsonRequestBehavior.AllowGet);
    }
}

VIEW:

观点:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<script type="text/javascript">
    var myApp = angular.module("app", []);

    myApp.controller('controller', function ($scope, $http) {

        $scope.GetFullName = function (employee) {

            //The url is as follows - ControllerName/ActionName?name=nameValue&surname=surnameValue

            $http.get("/Angular/GetFullName?name=" + $scope.name + "&surname=" + $scope.surname).
            success(function (data, status, headers, config) {
                alert('Your full name is - ' + data.fullName);
            }).
            error(function (data, status, headers, config) {
                alert("An error occurred during the AJAX request");
            });

        }
    });

</script>

<div ng-app="app" ng-controller="controller">

    <input type="text" ng-model="name" />
    <input type="text" ng-model="surname" />
    <input type="button" ng-click="GetFullName()" value="Get Full Name" />
</div>
