Vue3加载远程服务器的svg图标文件

Vue3加载远程服务器的svg图标文件，并实现颜色、大小的可控

准备svg文件

<svg width="inherit" height="inherit" viewBox="0 0 20 20" fill="currentColor" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
    <rect id="ic-用户" width="20.000000" height="20.000000" fill="inherit" fill-opacity="0"/>
    <path id="矢量 77" d="M6 6C6 3.79 7.8 2 10 2C12.2 2 14 3.79 14 6C14 8.2 12.2 10 10 10C7.8 10 6 8.2 6 6ZM12.5 6C12.5 4.59 11.4 3.5 10 3.5C8.59 3.5 7.5 4.59 7.5 6C7.5 7.4 8.59 8.5 10 8.5C11.4 8.5 12.5 7.4 12.5 6ZM3.5 12.7C5.59 11.6 7.8 11.1 10 11.1C12.2 11.1 14.4 11.7 16.5 12.7C16.79 12.9 17 13.2 17 13.6L17 17C17 17.6 16.6 18 16 18L4 18C3.4 18 3 17.6 3 17L3 13.6C3 13.2 3.19 12.9 3.5 12.7ZM15.5 13.9C13.8 13 11.9 12.6 10 12.6C8.09 12.6 6.19 13.1 4.5 13.9L4.5 16.5L15.5 16.5L15.5 13.9Z" fill="inherit" fill-opacity="1.000000" fill-rule="evenodd"/>
</svg>

注意点

• width、height 值要设置为 inherit
• fill 值设置为 currentColor
• 内部元素标签的 fill 值设置为 inherit

封装iconSvg.vue组件

<template>
    <div
        :style="{
            color: color,
            width: width,
            height: height,
            transform: transform,
        }"
        v-html="svgContent"
    ></div>
</template>

<script setup >
import { onMounted, ref, computed, onBeforeUnmount } from "vue";
import axios from "axios";

const props = defineProps({
    type: {
        type: String,
        default: "",
    },
    color: {
        type: String,
        default: "#00ff00",
    },
    width: {
        type: String,
        default: "20px",
    },
    height: {
        type: Number,
        default: "20px",
    },
    rotate: {
        type: Number,
        default: 0,
    },
    scale: {
        type: Number,
        default: 1,
    },
});

const svgContent = ref("");
const transform = computed(() => {
    return "rotate(" + props.rotate + "deg) scale(" + props.scale + ")";
});

onMounted(() => {
    axios.get(props.type).then((res) => {
        svgContent.value = res.data;
    });
});
</script>

<style scoped lang="less">
</style>

测试 test.vue

<template>
    <div style="position: relative; top: 50%; left: 50%">
        <iconSvg
            :type="svgInfo.type"
            :color="svgInfo.color"
            :width="svgInfo.width"
            :height="svgInfo.height"
            :rotate="svgInfo.rotate"
            :scale="svgInfo.scale"
        ></iconSvg>
    </div>
</template>

<script setup >
import { onMounted, reactive, ref } from "vue";
import iconSvg from "./iconSvg/index.vue";

const svgInfo = reactive({
    type: "sidebar-user.svg",
    color: "#000000",
    width: "20px",
    height: "20px",
    rotate: 0,
    scale: 1,
});
    
setInterval(() => {
    let r = 255 * Math.random();
    let g = 255 * Math.random();
    let b = 255 * Math.random();
    svgInfo.color = `rgb(${r},${g},${b})`;
    svgInfo.width = "20px";
    svgInfo.height = "20px";
    svgInfo.rotate += 1;
    svgInfo.scale += 0.02;
}, 100);

</script>
