Overview
Use $httpProvider to change the default behavior of the $http service.
Methods
useApplyAsync([value]);
Configure $http service to combine processing of multiple http responses received at around the same time via $rootScope.$applyAsync. This can result in significant performance improvement for bigger applications that make many HTTP requests concurrently (common during application bootstrap).
Defaults to false. If no value is specified, returns the current configured value.
Parameters
Param Type Details value (optional)booleanIf true, when requests are loaded, they will schedule a deferred "apply" on the next tick, giving time for subsequent requests in a roughly ~10ms window to load and share the same digest cycle.
Returns
booleanObjectIf a value is specified, returns the $httpProvider for chaining. otherwise, returns the current configured value.
Properties
defaults
Object containing default values for all $http requests.
defaults.cache- {boolean|Object} - A boolean value or object created with$cacheFactoryto enable or disable caching of HTTP responses by default. See $http Caching for more information.defaults.headers- {Object} - Default headers for all $http requests. Refer to $http for documentation on setting default headers.defaults.headers.commondefaults.headers.postdefaults.headers.putdefaults.headers.patch
defaults.jsonpCallbackParam-{string}- the name of the query parameter that passes the name of the callback in a JSONP request. The value of this parameter will be replaced with the expression generated by the$jsonpCallbacksservice. Defaults to'callback'.defaults.paramSerializer-{string|function(Object<string,string>):string}- A function used to the prepare string representation of request parameters (specified as an object). If specified as string, it is interpreted as a function registered with the $injector. Defaults to $httpParamSerializer.defaults.transformRequest-{Array<function(data, headersGetter)>|function(data, headersGetter)}- An array of functions (or a single function) which are applied to the request data. By default, this is an array with one request transformation function:- If the 
dataproperty of the request configuration object contains an object, serialize it into JSON format. 
- If the 
 defaults.transformResponse-{Array<function(data, headersGetter, status)>|function(data, headersGetter, status)}- An array of functions (or a single function) which are applied to the response data. By default, this is an array which applies one response transformation function that does two things:- If XSRF prefix is detected, strip it (see Security Considerations in the $http docs).
 - If the 
Content-Typeisapplication/jsonor the response looks like JSON, deserialize it using a JSON parser. 
defaults.xsrfCookieName- {string} - Name of cookie containing the XSRF token. Defaults value is'XSRF-TOKEN'.defaults.xsrfHeaderName- {string} - Name of HTTP header to populate with the XSRF token. Defaults value is'X-XSRF-TOKEN'.
interceptors
Array containing service factories for all synchronous or asynchronous $http pre-processing of request or postprocessing of responses.
These service factories are ordered by request, i.e. they are applied in the same order as the array, on request, but reverse order, on response.
