如何在 React 中从 POST API 调用中渲染数据

Question

I'm trying to figure out how to code my current API call so that I can access each field from the API call and render it, then be able to use it across multiple components. I'm using the QuickBase API call that only allows POST to pull field values. I've been out of the game for a couple of years and can't figure out how to accurately render these to be able to be used in other components by importing the api.js file. The project is a React within Electron to pull QuickBase data, and be able to create Line Charts (7 on one page) to show a job cost/hours and the jobs included departments cost/hours. All of my data is in quickbase, I just can't figure out how to get it over to react and able to actually use it!

Here is my API call:

let headers = {
  'QB-Realm-Hostname': 'XXXXXXXXX.quickbase.com',
  'User-Agent': 'FileService_Integration_V2.1',
  'Authorization': 'QB-USER-TOKEN XXXXXX_XXXXX_XXXXXXXXXXXXXXX',
  'Content-Type': 'application/json'
}
let body = {"from":"bpz99ram7","select":[3,6,80,81,82,83,86,84,88,89,90,91,92,93,94,95,96,97,98,99,101,103,104,105,106,107,109,111,113,115,120,123,224,225,226,227,228,229,230,231,477,479,480,481],"sortBy":[{"fieldId":6,"order":"ASC"}],"groupBy":[{"fieldId":40,"grouping":"equal-values"}],"options":{"skip":0,"top":0,"compareWithAppLocalTime":false}}

fetch('https://api.quickbase.com/v1/records/query',
  {
    method: 'POST',
    headers: headers,
    body: JSON.stringify(body)
  })
  
.then(res => {
  if (res.ok) {
    return res.json().then(res => console.log(res));
  }

return res.json().then(resBody => Promise.reject({status: res.status, ...resBody}));
})

.catch(err => console.log(err))

Any help would be greatly appreciated as I've been struggling on this for awhile. Right now I'm able to get all the correct data in the Console. But don't know how to go about rendering it on my application for actual use.

Thanks!

I think you should put your code inside a function and call that function from the component where you need the data, something like

import React, { Component } from 'react'

let headers = {
  'QB-Realm-Hostname': 'XXXXXXXXX.quickbase.com',
  'User-Agent': 'FileService_Integration_V2.1',
  'Authorization': 'QB-USER-TOKEN XXXXXX_XXXXX_XXXXXXXXXXXXXXX',
  'Content-Type': 'application/json'
};

class App extends Component {
  state = {
    data: null,
  }

  componentDidMount() {
    this.fetchData();
  }    

  fetchData = () => {    
    let body = {"from":"bpz99ram7","select":[3,6,80,81,82,83,86,84,88,89,90,91,92,93,94,95,96,97,98,99,101,103,104,105,106,107,109,111,113,115,120,123,224,225,226,227,228,229,230,231,477,479,480,481],"sortBy":[{"fieldId":6,"order":"ASC"}],"groupBy":[{"fieldId":40,"grouping":"equal-values"}],"options":{"skip":0,"top":0,"compareWithAppLocalTime":false}}

    fetch('https://api.quickbase.com/v1/records/query', {
      method: 'POST',
      headers: headers,
      body: JSON.stringify(body)
    }).then(response => {
      if (response.ok) {
        return response.json().then(res => {
          this.setState({
            data: res,
          })
        });
      }

      return response.json().then(resBody => Promise.reject({status: response.status, ...resBody}));
    }).catch(err => console.log(err))
  }

  render() {
    const { data } = this.state;

    if (data === null) return 'Loading...';

    return (
      <div>
        {/* Do something with data */}
      </div>
    );
  }
}

export default App;

Check the Docs , you can send the JSON in the props of the component to render it. You can modify your code following this example.

import { useEffect, useState } from "react";

async function apiCall() {
  return await new Promise((resolve, reject) => {
    // Api Call
    fetch("https://jsonplaceholder.typicode.com/todos/1")
      .then((response) => response.json())
      .then((json) => resolve(json));
  });
}
const TestApp = () => {
  let [data, setData] = useState({ Text: "Before api call." });

  useEffect(() => {
    (async () => {
      let res = await apiCall();
      res.Text = "After api call.";
      setData(res);
    })();
  }, []);
  return (
    <div>
      UserId: {data.userId} &nbsp; id: {data.id} &nbsp; title: {data.title}{" "}
      &nbsp; completed: {data.completed}
    </div>
  );
};

module.exports = TestApp;
