Angular中的http.get与http.request

Question

I noticed people use 2 ways of retrieving data from remote source: http.get() and http.request() .

What is the difference between http.get() and http.request() method in Angular?

Answer 1

http.get() is just a shorthand to using http.request() with the method field of the Request argument set as RequestMethod.Get .

The same goes for the http methods named with a HTTP verb :

• http.put()
• http.post()
• http.delete()
• http.head()
• http.patch()
• http.options()

(with, depending on the method, some convenient other arguments as shortcut for the relevant RequestOption , such as body for http.post() )

So the actual only difference is just readability , but that's IMHO important enough to prefer these specific methods over directly using http.request()

For information, here is the relevant documentation link : https://angular.io/api/http/Http#members , a good place to start for any basic question on the meaning and syntax of the common Angular objects and methods.

Also, don't forget that Angular is Open Source, you can just search for any code of the various packages, and have a look at it!
