async GET request with body from browser

由 流过昼夜 提交于 2019-12-08 07:51:08
问题 Ok, I know it's a bad idea and it shouldn't be done but for the sake of this question please assume there's no other way - I am given API endpoint that requires GET request with empty object as a body. Is there a way to do async request from browser? I'm using axios library which uses XMLHttpRequest under the hood and MDN says that send wipes the body when HTTP method is GET . I tried using native fetch but it gives me this error in browser: TypeError: Failed to execute 'fetch' on 'Window':

But, if I make an API request that requires a Token, I get: Access to XMLHttpRequest at 'localhost:8000/api/TestConnection/' from origin ' http:/
