Node.js 节点将文件上载到S3错误InvalidArgument:null

我在aws sdk库中有此错误，但我没有找到原因

我已经尝试了很多天了，但是没有成功，也不知道发生了什么 这是一个状态码400，但我在网上查了很多例子，一切都很好

这是密码

var AWS = require('aws-sdk');
AWS.config.update({ region: 'nyc3' });

var uuid = require('node-uuid');
var fs = require('fs');

// Create an S3 client
var s3 = new AWS.S3({
  apiVersion: '2006-03-01',
  secretAccessKey: '*****',
  accessKeyId: '*****',
  endpoint: 'https://nyc3.digitaloceanspaces.com',
  region: 'nyc3'
});

AWS.config.region = 'nyc3';

const fileName = 'hello_world.txt';

// Create a bucket and upload something into it
var bucketName = 'my-bucket';
var keyName = fileName;

fs.readFile(fileName, (err, data) => {
  if (err) throw err;
  var params = {
    ACL: 'private',
    Bucket: bucketName,
    Key: keyName,
    Body: JSON.stringify(data, null, 2),
    ContentLength: data.length
  };
  s3.putObject(params, function(err, data) {
    if (err) console.log(err);
    else
      console.log(
        'Successfully uploaded data to ' + bucketName + '/' + keyName
      );
  });

  // s3.upload(params, function(s3Err, data) {
  //   if (s3Err) console.log(s3Err);
  //   else console.log(`File uploaded successfully at ${data.Location}`);
  // });
});

您可以看到，我尝试了putObject和upload方法，但它们都有相同的错误

我不知道我能做些什么来解决这个问题。

任何人都可以提供帮助？

在提交S3

putObject

调用之前，当您

console.log（data）

时会发生什么？Hi@TheLebDev这里是输出，因此您尝试上载的数据是

？是的，这是我想要上载的。我建议首先记录发送到putObject的每个参数，显然，有东西被解释为

null

并使您的呼叫崩溃。当您
