axios 发布方法错误反应

Question

Im trying to send data using axios post method but keep receiving error 415.

I tried switching to "'Content-Type': application/x-www-form-urlencoded" but still same problem.

Getting data with axios.get works without an error.

What am i doing wrong?

File in which i store API endpoints:

 import axios from "axios"; const api = () => { const baseUrl = "https://localhost:5001/api"; let optionAxios = { headers: { "Content-Type": "text/plain;charset=utf-8", }, }; return { getSubjects: () => axios.get(`${baseUrl}/subjectcontroller/getsubjects`), addSubject: (subjectName) => axios.post( `${baseUrl}/subjectcontroller/createsubject`, { name: subjectName, }, optionAxios ), }; }; export const apiService = api();

Component from which i send data:

 import Context from "../../store/context"; import FormContainer from "../UI/FormContainer"; import { apiService } from "../../services/api/api.service"; import { useContext, useRef } from "react"; const AddSubject = () => { const ctx = useContext(Context); const subject = useRef(""); const sendData = (e) => { e.preventDefault(); apiService.addSubject(subject.current.value); }; return ( <FormContainer show={ctx.subjectForm} send={sendData}> <label htmlFor="subject">Subject Name: </label> <input type="text" id="subject" ref={subject} /> <button type="submit">Add</button> </FormContainer> ); };

console logs

If your API expects a JSON body, you have to set the Content-Type headers as "application/json"

  const optionAxios = {
    headers: {
       'Content-Type': 'application/json',
    },
  };
