警告：道具类型失败：提供给`Image` 的道具`source` 无效我在对象中使用 require() 保存了图像的路径

问题描述

当我尝试获取以 require() 作为道具的 js 对象中的图像路径时，出现此错误。

Warning: Failed prop type: Invalid prop `source` supplied to `Image`.

CategoriesScreen.js

import React from "react";
import {
  View,Text,FlatList,StyleSheet,TouchableOpacity,} from "react-native";

import { CATEGORIES } from "../Data/Dummy-Data";
import CategoryGrid from "../component/categoryGrid";

const CategoriesScreen = (props) => {
  const renderGridItem = (itemData) => {
    return (
      <CategoryGrid
        title={itemData.item.title}
        imgurl={itemData.item.url}
//console.log (itemData.item.url)-> require(..) ->image path


        onSelect={() =>
          props.navigation.navigate({
            routeName: "CategoryMeals",params: {
              categoryId: itemData.item.id,},})
        }
      ></CategoryGrid>
    );
  };
  return (
    <View>
      <FlatList data={CATEGORIES} renderItem={renderGridItem} numColumns={2} />
    </View>
  );
};
CategoriesScreen.navigationoptions = {
  headerTitle: "Meals Categories",};
const styles = StyleSheet.create({
  screen: {
    flex: 1,justifyContent: "center",alignItems: "center",//this is unused till Now.
  },});

export default CategoriesScreen;

这里我保存了所有图片的路径

虚拟数据.js

import Category from "../Models/category";

export const CATEGORIES = [
  new Category("C1","Italian","require('../assets/Images/italian.jpeg')"),new Category("C2","Indian","require('../assets/Images/Indian.jpeg')"),new Category("C3","french","require('../assets/Images/french.jpeg')"),new Category(
    "C4","Hamburgers","require('../assets/Images/Hamburgers.jpeg')"
  ),new Category("C5","German","require('../assets/Images/German.jpeg')"),new Category("C6","Asian","require('../assets/Images/Asian.jpeg')"),new Category("C7","Breakfast","require('../assets/Images/Breakfast.jpeg')"),new Category("C8","Dinner","require('../assets/Images/Dinner.jpeg')"),];

category.js

class Category {
  constructor(id,title,url) {
    this.id = id;
    this.title = title;
    this.url = url;
  }
}
export default Category;

CategoryGrid.js

import React from "react";
import {
  TouchableOpacity,View,imagebackground,} from "react-native";

const CategoryGrid = (props) => {
  return (
    <TouchableOpacity style={styles.gridItems} onPress={props.onSelect}>
      <View>
        <imagebackground
          source={props.imgurl}
          style={{ width: "100%",height: "90%" }}
        />
        <Text>{props.title}</Text>
      </View>
    </TouchableOpacity>
  );
};

const styles = StyleSheet.create({
  gridItems: {
    flex: 1,margin: 15,height: 150,});

export default CategoryGrid;

console.log() 在 CategoriesScreen.js 和 categoryGrid.js 中说 -> require(../assests/Images/image.jpeg)

我正在尝试将图像路径作为从 CategoryScreen.js 到 categoryGrid.js 的道具，后者作为对象存储在 Dummy-Data.js 中。

知道我做错了什么吗？

解决方法

这样做

<ImageBackground
  source={{uri: props.imgUrl}}
  style={{ width: "100%",height: "90%" }}
/>

,

import Category from "../Models/category";

export const CATEGORIES = [
  new Category("C1","Italian",require("../assets/Images/italian.jpeg")),new Category("C2","Indian",require("../assets/Images/Indian.jpeg")),new Category("C3","French",require("../assets/Images/French.jpeg")),new Category("C4","Hamburgers",require("../assets/Images/Hamburgers.jpeg")),new Category("C5","German",require("../assets/Images/German.jpeg")),new Category("C6","Asian",require("../assets/Images/Asian.jpeg")),new Category("C7","Breakfast",require("../assets/Images/Breakfast.jpeg")),new Category("C8","Dinner",require("../assets/Images/Dinner.jpeg")),];
