问题
Suppose that all of my Rest API need to accept following parameters:
1) param1
2) param2
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.
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: $resource('/api/entries2/:param1/:param2',
{param1:'@param1', param2: '@param2'}, {
})
});
I expect something like this from the final optimize code.
angular.module('myApp.services').config($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'),
{}, {
})
});
回答1:
You have to create an interceptor service and then add the interceptor to the $httpProvider in your app.config().
Create your interceptor service:
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;
}
}
To register with app config, add $httpProvider to app.config
app.config([...,'$httpProvider'...){
$httpProvider.interceptor.push('myInterceptorService');
}
