AWS Rekognition 错误 - InvalidparameterException

Question

const AWS = require('aws-sdk');
AWS.config.loadFromPath('./config.json');
const rekognition = new AWS.Rekognition({apiVersion: '2016-06-27'});
const constants = require('./constants');
const s3BucketName = constants.s3BucketName;
const s3BucketKeyName = constants.s3FacebookBucketKey;

const params = {
    Image: {
        S3Object: {
            Bucket: "mastekinnoations3learning",
            Name: "1527119837382460.jpeg"
        }
    }
};

rekognition.detectFaces(params, function(err, data) {
if (err)
console.log(err, err.stack); // an error occurred
else     {
    console.log(data);           // successful response
}
});

我正在尝试执行上个月成功运行的上述代码，但它突然停止运行，出现错误“InvalidParameterException”。任何我所缺少的帮助都会有很大的帮助！

我正在使用的图像是这个

Answer 1

问题出在图片上。它似乎已损坏（仍然在 MSPaint 中完美打开）。如果我在 MSPaint 中打开图像并将其另存为 JPEG 并尝试将其传递给 AWS Rekognition ，则它可以正常工作。因此，我尝试了一种不同的方法来从 facebook 页面下载图像并且应用程序工作正常。 谢谢！！

Answer 2

在config.json，有一些东西。 试试这个

AWS.config.update({region:'us-east-1',accessKeyId:'',secretAccessKey:''});

让我们改变 Bucket 这个。

const s3bucket = new AWS.S3({params: {Bucket: ''}}); //name Bucket you

Answer 3

试试这个代码。必需的属性

const params = {
         Image: {
           S3Object: {
              Bucket: "mastekinnoations3learning",
              Name: "1527119837382460.jpeg"
          }
      },
     Attributes:["ALL"]
 };
