在每个http请求中添加通用参数 [英] Add common parameter in each http request
问题描述
假设我所有的Rest API都需要接受以下参数:
1)param1
2)param2
Suppose that all of my Rest API need to accept following parameters:
1) param1
2) param2
以这种方式实现(对下面的代码而言)对我来说是很麻烦的. 此外,它违反了DRY的概念.我要寻找的是一个全局配置,该配置允许将默认参数与http请求一起传递.
It would be tedious for me to implement this way (refer to code right below). Moreover, it defies the concept of DRY. What I am looking for is a global configuration that allows default parameter to be passed along with the http request.
我相信 $ httpProvider 是我可以获得的最接近的(因为它可以全局定义cookie到期时间,标头等),但似乎找不到使用它传递参数的方法.
I believe that $httpProvider is the closest i can get (since it can define cookie expiry, header etc globally) but it seems that i could not find the way of using it to pass parameters.
angular.module('myApp.services').factory('Entry', function($resource) {
return {
method1: $resource('/api/entries/:id/:param1/:param2',
{ id: '@_id', param1:'@param1', param2: '@param2'}, {
update: {
method: 'PUT' // this method issues a PUT request
}
}),
method2: $resource('/api/entries2/:param1/:param2',
{param1:'@param1', param2: '@param2'}, {
})
});
我希望最终的优化代码中有类似的内容.
I expect something like this from the final optimize code.
angular.module('myApp.services').config($httpProvider){
$httpProvider.defaults.param('param1');
$httpProvider.defaults.param('param2');
}
angular.module('myApp.services').factory('Entry', function($resource) {
return {
method1: $resource('/api/entries/:id/',
{ id: '@_id' }, {
update: {
method: 'PUT' // this method issues a PUT request
}
}),
method2: $resource('/api/entries2'),
{}, {
})
});
推荐答案
您必须创建一个拦截器服务,然后将该拦截器添加到app.config()中的$ httpProvider中.
You have to create an interceptor service and then add the interceptor to the $httpProvider in your app.config().
创建拦截器服务:
angular.module('app').factory('myInterceptorService', myInterceptorService);
function myInterceptorService(){
var param1,param2;
return{
request: requestInterceptor,
setParams: setParams
};
function requestInterceptor(config){
config.params.push(param1);
config.params.push(param2);
return config;
}
function setParams(p1,p2){
param1=p1;
param2=p2;
}
}
要向app config注册,请将$ httpProvider添加到app.config
To register with app config, add $httpProvider to app.config
app.config([...,'$httpProvider'...){
$httpProvider.interceptor.push('myInterceptorService');
}
