안녕하세요
강의를 듣다가 이미지 로딩에 계속 문제가 생겨 문의 드립니다.
* 오류 (ERR_SSL_PROTOCOL_ERROR)
- 이미지 등록 시 uploads 폴더에서 이미지 확인됨
- ERR_SSL_PROTOCOL_ERROR
-> 해당 출처(https://onna.kr/484)를 통해 한 번씩 다 시도해봄
Client
- FileUpload.js
import React, { useState } from "react";
import Dropzone from "react-dropzone";
import { PlusOutlined } from "@ant-design/icons";
import axios from "axios";
function FilUpload() {
//저장하기 전 state에 저장
const [Images, setImages] = useState([]);
const dropHandler = (files) => {
let formData = new FormData();
const config = {
header: { "content-type": "multipart/form-data" },
};
formData.append("file", files[0]);
axios.post("/api/product/image", formData, config).then((response) => {
if (response.data.success) {
// console.log(response.data);
//원래있던 이미지 다 넣게 됨
setImages([...Images, response.data.filePath]);
} else {
alert("파일을 저장하는데 실패했습니다.");
}
});
};
return (
<div style={{ display: "flex", justifyContent: "space-between" }}>
<Dropzone onDrop={dropHandler}>
{({ getRootProps, getInputProps }) => (
<div
style={{
width: 300,

ssl 인증이슈는 https 를 통해 데이터를 불러오기 때문입니다.
이미지를 불러오는 부분의 src 부분을 아래와 같이 http로 불러오도록 수정해 보세요.
{Images.map((image,index) => (
<img key={index} style={{minWidth:'300px', width: '300px', height:'240px'}}
src = {`http://localhost:5000/${image}`} />
))}
