AI来实现代码转换！Python转Java，Java转Go不在话下？

今天看到个有趣的网站，给大家分享一下。

该网站的功能很神奇，可以实现编程语言的转化。感觉在一些场景之下还是有点作用的，比如你原来跟我一样是做Java的，因为工作需要突然转Go。这个时候用你Java的经验 + 这个工具，或许可以起到一定的帮助作用。

工具的使用也很简单，只需要在左侧黏贴你想转换的原始代码，然后点击CONVERT CODE，右侧输入框就会转换成目标代码：

是不是很神奇？关注公众号“程序猿DD”，回复“代码转换”获取网站地址，一起来试试看吧！

也许你跟我一样，觉得只能实现这样简单的代码转换。但实际上像下面这样更加复杂的代码转换也是不在话下：

const fs = require('fs');
 const AWS = require('aws-sdk');
 
 const s3 = new AWS.S3({
     accessKeyId: process.env.AWS_ACCESS_KEY,
     secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY
 });
 
 const fileName = 'contacts.csv';
 
 const uploadFile = () => {
   fs.readFile(fileName, (err, data) => {
       if (err) throw err;
       const params = {
           Bucket: 'testBucket', // pass your bucket name
           Key: 'contacts.csv', // file will be saved as testBucket/contacts.csv
           Body: JSON.stringify(data, null, 2)
       };
       s3.upload(params, function(s3Err, data) {
           if (s3Err) throw s3Err
       });
   });
 };
 
 uploadFile();

可以看到其中还包含了aws的内容，居然也能顺利的转成Java。

import java.io.File;
import java.io.IOException;
import java.util.Scanner;

import com.amazonaws.AmazonServiceException;
import com.amazonaws.SdkClientException;
import com.amazonaws.auth.profile.ProfileCredentialsProvider;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3ClientBuilder;
import com.amazonaws.services.s3.model.ObjectMetadata;
import com.amazonaws.services.s3.model.PutObjectRequest;

public class UploadObject {

    public static void main(String[] args) throws IOException {
        String clientRegion = "*** Client region ***";
        String bucketName = "*** Bucket name ***";
        String stringObjKeyName = "*** String object key name ***";
        String fileObjKeyName = "*** File object key name ***";
        String fileName = "*** Path to file to upload ***";

        try {
            AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
                    .withRegion(clientRegion)
                    .withCredentials(new ProfileCredentialsProvider())
                    .build();

            // Upload a text string as a new object.
            s3Client.putObject(bucketName, stringObjKeyName, "Uploaded String Object");

            // Upload a file as a new object with ContentType and title specified.
            PutObjectRequest request = new PutObjectRequest(bucketName, fileObjKeyName, new File(fileName));
            ObjectMetadata metadata = new ObjectMetadata();
            metadata.setContentType("plain/text");
            metadata.addUserMetadata("x-amz-meta-title", "someTitle");
            request.setMetadata(metadata);
            s3Client.putObject(request);
        }
        catch(AmazonServiceException e) {
            // The call was transmitted successfully, but Amazon S3 couldn't process 
            // it, so it returned an error response.
            e.printStackTrace();
        }
        catch(SdkClientException e) {
            // Amazon S3 couldn't be contacted for a response, or the client
            // couldn't parse the response from Amazon S3.
            e.printStackTrace();
        }
    }
}

根据官方说明，该工具也是通过AI实现的，是不是很神奇呢？这个到底是怎么实现的呢？有了解的小伙伴留言区一起探讨下吧！
