javascript - Response for preflight has invalid HTTP status code 400 using Axios -


i'm using axios library make api call in react application.i call api , populate table using react.

my axios call follows:

     axios({       method: 'get',       url: dataurl,       headers: {         'content-type' : 'application/json',         'id': user.id,         'name' : user.name,         'api-token' : user.access_token,         'clientid' : 'web',     },     responsetype: 'json',   })     .then((response) => {       this.setstate({ tabledata: response.data });     });

however error:

xmlhttprequest cannot load my api url response preflight has invalid http status code 400

the same working in dev environment wasn't adding headers, after migrating new env required me add headers, im getting above error. question is, client side issue(like wrong header format etc) or server side handling of api call?

i think server-side issue. if using node in background need cors middleware (https://www.npmjs.com/package/cors). other server solutions there of course cors request handler.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
