我目前正在使用React，Redux，JavaScript，Node，Adonisjs构建注册表单。我正在尝试将个人资料图像上传到我的AWS s3存储桶。目前，我已经知道了，因此文件出现在存储桶中。但是，当我尝试单击AWS s3提供的链接时，出现以下错误。 AWS ERROR IMAGE。
我已将我的权限设置为公开，并且我提供了正确的凭据密钥。我坚持如何解决此问题，因此将不胜感激任何帮助。请参见下面的代码。
下面是我的AWS控制器：
"use strict";
require("dotenv").config();
const aws = require("aws-sdk");
const fs = require("fs");
const Helpers = use("Helpers");
const Drive = use("Drive");
class awsController {
async upload({ request, response }) {
aws.config.update({
region: "ap-southeast-2", // AWS region
accessKeyId: process.env.S3_KEY,
secretAccessKey: process.env.S3_SECERT
});
const S3_BUCKET = process.env.S3_BUCKET;
const s3Bucket = new aws.S3({
region: "ap-southeast-2",
accessKeyId: process.env.S3_KEY,
secretAccessKey: process.env.S3_SECERT,
Bucket: process.env.S3_BUCKET
}); // Create a new instance of S3
const fileName = request.all().body.fileName;
console.log(fileName);
const fileType = request.all().body.fileType;
const params = {
Bucket: S3_BUCKET,
Key: fileName,
ContentType: fileType,
ACL: "public-read"
};
s3Bucket.putObject(params, function(err, data) {
if (err) {
response.send(err);
}
console.log(data);
const returnData = {
signedRequest: data,
url: `https://${S3_BUCKET}.s3.amazonaws.com/${fileName}`
};
console.log(returnData);
response.send("Success");
});
}
}
module.exports = awsController;
**下面处理文件的上传**
import React, { Component } from "react";
import axiosAPI from "./../resorterAPI";
import axios from "axios";
class ImageUpload extends Component {
constructor(props) {
super(props);
this.state = {

let uploadedFile = this.uploadInput.files[0];
// Splits name of file
let fileParts = this.uploadInput.files[0].name.split(".");
let fileName = fileParts[0];
let fileType = fileParts[1];
let fullFileName = uploadedFile.name;
console.log("preparing upload");
axiosAPI
.post("/s3Upload", {
body: {
fileName:
Math.round(Math.random() * 1000 * 300000).toString() +
"_" +
uploadedFile.name,
fileType: fileType
}
})
.then(response => {
console.log("Success");
});

更新：感谢Jarmod解决了该错误，实际上我没有将文件扩展名与文件名分开，因此它正在上传image.png.png。但是，现在存在一个问题，其中上载的文件没有内容，并且是一个空文本文件。
@@ jarmod-感谢您的回复。
这将我引向正确的方向。我到底需要在对象中放入什么？当我按如下所示放入完整文件对象时，它没有出现在s3存储桶中，但成功返回。然后，当我只输入fileName时，它会返回fileName的txt文件。任何帮助将不胜感激。
// The below collects the data from the post including filename, type and the complete file object.
const uploadedFile = request.all().body.file;
const fileName = request.all().body.fileName;
const fileType = request.all().body.fileType;
console.log(fileType);
console.log(fileName);
// The below defines the params.
const params = {
Bucket: S3_BUCKET,
Key: fileName,
Body: file,
ContentType: fileType,
ACL: "public-read"
};
// The below sends the object off to AWS s3
s3Bucket.putObject(params, function(err, data) {
if (err) {
response.send(err);
}
const returnData = {
signedRequest: data,
url: `https://${S3_BUCKET}.s3.amazonaws.com/${fileName}`
};
console.log("Success");
response.send(returnData);
});
}
