So I am building a dynamic lesson page with GraphQl and React.
I built a custom hook, and I do not know how to pass the ID up to the config data.
This is my hook that I made.
This is my first time working with GraphQL
import axios from 'axios'
import { useState, useEffect } from 'react'
const { REACT_APP_SPACE_ID, REACT_APP_CDA_TOKEN } = process.env
var data = JSON.stringify({
query: `{
lesson(id: ${id}){
shortTitle
shortDescription
}
}`,
variables: {},
})
var config = {
method: 'post',
url: `https://graphql.contentful.com/content/v1/spaces/${REACT_APP_SPACE_ID}`,
headers: {
Authorization: `Bearer ${REACT_APP_CDA_TOKEN}`,
'Content-Type': 'application/json',
},
data: data,
}
export default function GetLesson(id) {
let [data, setData] = useState()
useEffect(() => {
getContent()
}, [])
const getContent = async () => {
await axios(config)
.then(function (response) {
setData(response.data.data.lesson)
})
.catch(function (error) {
console.log(error)
})
}
return { data }
}
This is the url I am getting. I want to access customer id and date from the url to function
but because this is not the default class, I am not able to do it and I need help.
http://localhost:3000/update?customer=66&date=2022-06-27&tab=user
const getData = (props) => {
const config = {
headers: {
Authorization: `token ` + localStorage.getItem("token"),
},
};
console.log(props.customer);
return axios
.get(
"api?customer=" +this.props.customer+"&date=" + this.props.date,
config
)
.then((res) => res.data)
.catch((err) => {
console.error("error ocurred while fetching data", err);
return null;
});
};
full code i have given in sandbox for refernce

If you have react-router-dom in your project, you might use useLocation hook
import {useLocation} from 'react-router-dom'
const search = useLocation().search
console.log(URI.parseQuery(search))
I am try to fetch users information using github API
import React, { useEffect } from "react";
function UserResults() {
useEffect(() => {
fetchUsers();
}, []);
const fetchUsers = async () => {
const response = await fetch(`${process.env.REACT_APP_GITHUB_URL}/users`, {
headers: {
Authorization: `token ${process.env.REACT_APP_GITHUB_TOKEN}`,
},
});
const data = response.json();
};
return <div>Hello</div>;
}
export default UserResults;
And here is what I put in my env:
REACT_APP_GITHUB_TOKEN="<token>"
REACT_APP_GITHUB_URL = "https://api.github.com"
I am sure the token is correctly generated and copied.
But it seems I can't fetch the data due to some "JSON" error as it shows in the console like this.
Can anyone offers any help with this?
You need to await response.json() and update your header request
import React, { useEffect } from "react";
function UserResults() {
useEffect(() => {
fetchUsers();
}, []);
const fetchUsers = async () => {
const response = await fetch(`${process.env.REACT_APP_GITHUB_URL}/users`, {
headers: {
'Authorization': `token ${process.env.REACT_APP_GITHUB_TOKEN}`,
'Content-Type': 'application/json',
'Accept': 'application/json'
},
});
const data = await response.json();
};
return <div>Hello</div>;
}
export default UserResults;
i am trying to change the api fetch into axios get method i dont know how to do that
const fetchApi = () => {
const request = getAllActivityData();
request
.api({
params: {
customer,
},
})
i want to call api like this using axios
i have added full code in codesandbox it will be helpfull if u can edit the codesand box and make it working
useEffect(() => {
const config = {
headers: {
Authorization: `token
},
};
axios.get("customer/get-all-activity-data/?customer=22", config)
.then((res) => {
console.log(res.data);
});

Do you mean something like this, using async await...
const axiosCallFn = async () => {
let url = '...'
let config = {
headers: {
token: '...'
}
}
try {
let resp = await axios.get(url, config)
return resp.data
} catch(e) {
throw e
}
}
// import the function into your component and use it like so
axiosCallFn()
.then((data) => {
// your functionality here.
})
.catch(() => {
// your error functionality here.
})
and then you can call your axiosCallFn in your useEffect.
I am new to ReactJS and UI and I wanted to know how to make a simple REST based POST call from ReactJS code.
If there is any example present it would be really helpful.
Straight from the React Native docs:
fetch('https://mywebsite.example/endpoint/', {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify({
firstParam: 'yourValue',
secondParam: 'yourOtherValue',
})
})
(This is posting JSON, but you could also do, for example, multipart-form.)
Also see docs for ReactJS AJAX FAQs if not using React Native.
React doesn't really have an opinion about how you make REST calls. Basically you can choose whatever kind of AJAX library you like for this task.
The easiest way with plain old JavaScript is probably something like this:
var request = new XMLHttpRequest();
request.open('POST', '/my/url', true);
request.setRequestHeader('Content-Type', 'application/json; charset=UTF-8');
request.send(data);
In modern browsers you can also use fetch.
If you have more components that make REST calls it might make sense to put this kind of logic in a class that can be used across the components. E.g. RESTClient.post(…)
Another recently popular packages is : axios
Install : npm install axios --save
Simple Promise based requests
axios.post('/user', {
firstName: 'Fred',
lastName: 'Flintstone'
})
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
});
you can install superagent
npm install superagent --save
then for make post call to server
import request from "../../node_modules/superagent/superagent";
request
.post('http://localhost/userLogin')
.set('Content-Type', 'application/x-www-form-urlencoded')
.send({ username: "username", password: "password" })
.end(function(err, res){
console.log(res.text);
});
As of 2018 and beyond, you have a more modern option which is to incorporate async/await in your ReactJS application. A promise-based HTTP client library such as axios can be used. The sample code is given below:
import axios from 'axios';
...
class Login extends Component {
constructor(props, context) {
super(props, context);
this.onLogin = this.onLogin.bind(this);
...
}
async onLogin() {
const { email, password } = this.state;
try {
const response = await axios.post('/login', { email, password });
console.log(response);
} catch (err) {
...
}
}
...
}
I think this way also a normal way. But sorry, I can't describe in English ((
submitHandler = e => {
e.preventDefault()
console.log(this.state)
fetch('http://localhost:5000/questions',{
method: 'POST',
headers: {
Accept: 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify(this.state)
}).then(response => {
console.log(response)
})
.catch(error =>{
console.log(error)
})
}
https://googlechrome.github.io/samples/fetch-api/fetch-post.html
fetch('url/questions',{
method: 'POST',
headers: {
Accept: 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify(this.state)
}).then(response => {
console.log(response)
})
.catch(error =>{
console.log(error)
})
Here is a the list of ajax libraries comparison based on the features and support.
I prefer to use fetch for only client side development or isomorphic-fetch for using in both client side and server side development.
For more information on isomorphic-fetch vs fetch
Here is a util function modified (another post on stack) for get and post both. Make Util.js file.
let cachedData = null;
let cachedPostData = null;
const postServiceData = (url, params) => {
console.log('cache status' + cachedPostData );
if (cachedPostData === null) {
console.log('post-data: requesting data');
return fetch(url, {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify(params)
})
.then(response => {
cachedPostData = response.json();
return cachedPostData;
});
} else {
console.log('post-data: returning cachedPostData data');
return Promise.resolve(cachedPostData);
}
}
const getServiceData = (url) => {
console.log('cache status' + cachedData );
if (cachedData === null) {
console.log('get-data: requesting data');
return fetch(url, {})
.then(response => {
cachedData = response.json();
return cachedData;
});
} else {
console.log('get-data: returning cached data');
return Promise.resolve(cachedData);
}
};
export { getServiceData, postServiceData };
Usage like below in another component
import { getServiceData, postServiceData } from './../Utils/Util';
constructor(props) {
super(props)
this.state = {
datastore : []
}
}
componentDidMount = () => {
let posturl = 'yoururl';
let getdataString = { name: "xys", date:"today"};
postServiceData(posturl, getdataString)
.then(items => {
this.setState({ datastore: items })
console.log(items);
});
}
Here is the simple method to define and call post APIs in reactjs. Install axios using command npm install axios and call post req method wherever you want, it will return array that contains 100 elements.
// Define post_req() Method in authAction.js
import axios from 'axios';
const post_req = (data) => {
return new Promise((resolve, reject) => {
const url = 'https://jsonplaceholder.typicode.com/posts'
const header = {
"Access-Control-Allow-Origin": "*",
"Content-Type: application/json"
}
axios({
method: 'post',
url: url,
data: data,
headers: header
});
.then((res)=>{resolve(res);})
.catch((err)=>{reject(err);})
})
}
// Calling post_req() Method in react component
import React, { Component } from 'react';
import { post_req } from 'path of file authAction.js'
class MyReactComponent extends Component {
constructor(props) {
super(props);
this.state = {
myList:[]
};
}
componentDidMount() {
let data = {
.......
}
this.props.post_req(data)
.then((resp)=>{this.setState({myList:resp.data})})
.catch((err)=>{console.log('here is my err',err)})
}
render() {
return (
<div>
....
</div)
}
}
export default MyReactComponent;
import React ,{useState}from 'react';
import Axios from 'axios';
export default function Formlp()
{
const url ="";
const [state, setstate] = useState({
name:"",
iduser:""
})
function handel(e){
const newdata={...state}
newdata[e.target.id]=e.target.value
setstate(newdata);
}
function submit(e)
{
e.preventDefault();
// Axios.post(url,{name:state.name,iduser:state.iduser}).then( res=>{console.log(res)});
console.log(state)
}
return (
<div onSubmit={ (e)=> submit(e)}>
<input onChange={ (e)=>handel(e) } id="name" value={state.name} placeholder="name" type="text" >
<input onChange={ (e)=>handel(e) } id="iduser" value={state.iduser} placeholder="iduser" type="text" >
<button>submit</button>
</form>
</div>
);
}
Here is a quick example for v18+ while handling form data and creating a POST request with the data.
async function handleOrderSubmit(event){
event.preventDefault()
try{
const formData= {name: event.target.name.value, email: event.target.email.value, message: event.target.name.message}
const requestOptions = {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(formData)
};
const response = await fetch('https://www.example.com/form', requestOptions);
const data = await response.json();
navigate("/form-response", { state: {data: data, status: true} })
}
catch(error){
navigate("/form-response", { state: {status: false} })
}
}
Note 1: Using status on '/form-response' page, you can customise what to show user. For true, you can show a different section and for false a different one.
Note 2: If the status is successful, you can access data on the next page also and customise it according to user information.
Note 3: event.preventDefault() is important to avoid page reloading.
Here is an example: https://jsfiddle.net/69z2wepo/9888/
$.ajax({
type: 'POST',
url: '/some/url',
data: data
})
.done(function(result) {
this.clearForm();
this.setState({result:result});
}.bind(this)
.fail(function(jqXhr) {
console.log('failed to register');
});
It used jquery.ajax method but you can easily replace it with AJAX based libs like axios, superagent or fetch.
