AWS Rekognition Javascript SDK-未知错误：请求错误

我试图通过AWS Javascript SDK使用AWS Rekognition API，并在尝试启动其任何检测服务时收到

未知错误：错误请求

。我想运行标签检测，但在尝试其他操作（如名人面部检测）时出现相同的错误。我已确保我的帐户可以访问Rekognition API，并确保我的凭据正确无误（或者至少相同的凭据适用于连接到同一帐户的S3）

我的代码

var aws = require('aws-sdk');
const region = 's3-us-west-2';
const bucket = process.env.S3_VIDEO_BUCKET;
var requesttoken = randString(10) //generates random string
var key = 'path/to/key.mp4';

// used to check for keys to available files
var service = new aws.S3({
  accessKeyId: process.env.ACCESS_KEY,
  secretAccessKey: process.env.ACCESS_SECRET,
  region: region,
  endpoint: 'https://'+region+'.amazonaws.com/',
})

var rekognition = new aws.Rekognition({
  accessKeyId: process.env.ACCESS_KEY,
  secretAccessKey: process.env.ACCESS_SECRET,
  region: region,
  endpoint: 'https://'+region+'.amazonaws.com/',
  apiVersion: '2016-06-27'
})

// check that key is reachable in S3
this.service.getObject({Bucket:bucket,Key:key}, function(err, data){
  if(err){
    console.error(err, err.stack)
  } else {
    console.log(data)
  }
})

var params = {
  Video: {
    S3Object: {
      Bucket: bucket,
      Name: key
    }
  },
  ClientRequestToken: requesttoken,
  NotificationChannel: {
    RoleArn: 'arn:aws:sns:us-west-2:000000000:example',
    SNSTopicArn: 'example'
  }
};

rekognition.startContentModeration(params, (err,data)=>{
  if (err) {console.log(err, err.stack); return;};
  console.log(data)
})

当我运行这段代码时，我得到

我的问题

---

是否有人对Rekognition API/AWS和JS SDK足够熟悉，知道在这种情况下可能会出现什么错误请求？AWS文档中是否有说明此错误的地方？

从配置中删除端点，它会自动填充

而且这个配置是错误的

var rekognition = new aws.Rekognition({
accessKeyId: process.env.S3_ACCESS_KEY,
secretAccessKey: process.env.S3_BUCKET_ACCESS_SECRET,

---

您的访问密钥ID应该是AWS访问密钥，而不是S3访问密钥。除非S3环境变量指向您的实际AWS访问密钥（您可能应该重命名它们）

是。另外，文档中还提到：endpoint（String）——要向其发送请求的端点URI。默认端点是从配置的区域生成的。端点应该是类似于“https://{service}.{region}.amazonaws.com”的字符串谢谢您的响应！从收到的参数中删除端点时：

未知错误：永久移动

。假设S3_访问_密钥与AWS访问密钥相同是正确的。我最近开始尝试使用Rekognion，只是没有时间更新变量名。通过AWS文档检查，这表明端点不正确。是否可以更改端点，使自动填充端点不正确？我还通过输入

”进行了检查https://rekognition.“+region+”.amazonaws.com“

并且它还返回了

未知错误：永久移动了
。我在哪里可以检查正确的端点是什么？Rekognition端点：S3端点：永久移动可能也会引用S3命令，因此在每个错误之前放置一个console.log（'S3'）/console.log（'Rekognition'），以便缩小其范围。my region变量将S3烘焙到其中，因此，将其设置为重新命名的区域是在搞砸它。都修好了！
