importing image dynamically (React Js) (Require img path cannot find module)

问题

I need to import images(several) from my image file dynamically by a map method. First, I want to set a base URL to my images file and then read the image's name from my JSON file which includes the image property and then set the image src accordingly. The JSON file is like below :

{
      "title": "Blue Stripe Stoneware Plate",
      "brand": "Kiriko",
      "price": 40,
      "description": "Lorem ipsum dolor sit amet...",
      "image": "blue-stripe-stoneware-plate.jpg"
    },
    {
      "title": "Hand Painted Blue Flat Dish",
      "brand": "Kiriko",
      "price": 28,
      "description": "Lorem ipsum dolor sit amet...",
      "image": "hand-painted-blue-flat-dish.jpg"
    },

my images folder :

I have read the products by redux which is works perfectly =>

const products = this.props.products;
console.log(products, 'from redux'); 
const fetchProducts = [];
    for (let key in products) {
      fetchProducts.push({
        ...products[key]
      });
    }

the console.log() =>

Now I want to define a base URL like this which later use as image src by adding the image's name from the JSON file in the map method :

const baseUrl = '../../components/assets/images/';
const fetchProducts = [];
for (let key in products) {
  fetchProducts.push({
    ...products[key]
  });
}

const productCategory = fetchProducts.map((product, index) => {
  return (
    <Photo
      key={index}
      title={product.title}
      brand={product.brand}
      description={product.description}
      imageSource={baseUrl + product.image}
      imageAlt={product.title}
    />
  );
});

my Photo component looks like below :

  const photo = props => (
  <div className={classes.Column}>
    <img src={require( `${ props.imageSource }` )} alt={props.imageAlt} />
    <div className={classes.Container}>
      <p>{props.brand}</p>
      <p>{props.title}</p>
      <p>{props.price}</p>
    </div>
  </div>
);

export default photo;

unfortunately, I have faced this error: Thanks in advance and sorry for my bad English :)

回答1:

Import is not working like that. You can use a base URL like that:

const baseUrl = "../../components/assets/images/";

Then you can pass to your Photo component like that:

<Photo
  key={index} // Don't use index as a key! Find some unique value.
  title={product.title}
  brand={product.brand}
  description={product.description}
  imageSource={baseUrl + product.image}
  imageAlt={pro.title}
/>;

Lastly, in your Photo component use require:

<img src={require( `${ props.imageSource }` )} alt={props.imageAlt} />

or like that:

<img src={require( "" + props.src )} alt={props.imageAlt} />

But, don't skip "" part or don't use it directly like:

<img width="100" alt="foo" src={require( props.src )} />

since require wants an absolute path string and first two do this trick.
