fail to post with javascript fetch api to typicode json server










1















I have a react project where I try to post a JSON object to my Typicode mock json server. https://github.com/typicode/json-server#getting-started



The fetch fails, but I cannot pinpoint the issue. Maybe there is something wrong with the fetch call, I would like to know why and how to fix it.



Here is the react component that calls the fetch method.



import React from "react";

class AddAnimal extends React.Component
constructor(props)
super(props);
this.state = animal: "animal", amount: 0, price: 0, sound: "sound" ;


render()
return (
<form onSubmit=this.handleSubmit>
<input
type="text"
name="animal"
value=this.state.animal
onChange=this.handleOnChange
/>
<input
type="number"
name="amount"
value=this.state.amount
onChange=this.handleOnChange
/>
<input
type="number"
name="price"
value=this.state.price
onChange=this.handleOnChange
/>
<input
type="text"
name="sound"
value=this.state.sound
onChange=this.handleOnChange
/>
<input type="submit" className="btn" value="add Animal" />
</form>
);

handleOnChange = e =>
this.setState([e.target.name]: e.target.value );
console.log(this.state);
;

handleSubmit = e => this.state.price === 0


export default AddAnimal;


This is the fetch method being passed into the AddAnimal component as props.



 postAnimal(animal) 
fetch("https://localhost:3000/animals",
method: "POST",
headers:
Accept: "application/json",
"Content-Type": "application/json"
,
body: JSON.stringify(animal)
).then(response =>
console.log(response.json());
)



This is how the database looks and how it is structured. This is to show the format the JSON has to be in before getting posted.




"animals": [
"animal": "dogs",
"sound": "woof!",
"amount": 20,
"price": 200
,

"animal": "cats",
"sound": "meow!",
"amount": 15,
"price": 150
,

"animal": "horses",
"sound": "yhgighighrr",
"amount": 4,
"price": 950

]



This is the error the browser prompts me with when i try to submit my form after putting in details.

The typicode json-server only accepts an id on the objects from the database, and will not work with an https connection. You need to verify your backend, to make it work.
