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，但它已经停止运行，突然发出错误＆＃34; InvalidParameterException＆＃34;。任何帮助，没有我错过的将是非常有帮助!!

Answer 1

在config.json中，有一些东西。试试这个

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

让我们改变Bucket this。

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

Answer 2

试试这段代码。必需属性

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

参考： AWS SDK for JavaScript - Class: AWS.Rekognition

Answer 3

问题在于图像。它看似腐败（仍然在MSPaint完全打开）。如果我在MSPaint中打开图像并将其保存为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从Facebook页面下载图像，应用程序工作。谢谢！
