今天完成软件构造实验一的部分

实验一：百度机器翻译SDK实验（2024.11.15日完成）

    任务一：下载配置百度翻译Java相关库及环境（占10%）。

    任务二：了解百度翻译相关功能并进行总结，包括文本翻译-通用版和文本翻译-词典版（占20%）。

    任务三：完成百度翻译相关功能代码并测试调用，要求可以实现中文翻译成英文，英文翻译成中文（占30%）。

    任务四：完成百度翻译GUI相关功能代码并测试调用，要求可以实现中文翻译成英文，英文翻译成中文（占30%）。

    实验总结：（占10%）

从网上找到翻译的sdk

package com.mes.util;

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import okhttp3.*;
import org.json.JSONObject;

import java.io.IOException;

public class TransSDK {
    public static final String API_KEY = "uuuuuuuuuuuuuuuuu";
    public static final String SECRET_KEY = "uyuuuuuuuuuuuuuuuuuuuuu";

    static final OkHttpClient HTTP_CLIENT = new OkHttpClient().newBuilder().build();


//    /**
//     * 从用户的AK，SK生成鉴权签名（Access Token）
//     *
//     * @return 鉴权签名（Access Token）
//     * @throws IOException IO异常
//     */
    private static String getAccessToken() throws IOException {
        MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");
        RequestBody body = RequestBody.create(mediaType, "grant_type=client_credentials&client_id=" + API_KEY
                + "&client_secret=" + SECRET_KEY);
        Request request = new Request.Builder()
                .url("https://aip.baidubce.com/oauth/2.0/token")
                .method("POST", body)
                .addHeader("Content-Type", "application/x-www-form-urlencoded")
                .build();
        Response response = HTTP_CLIENT.newCall(request).execute();
        return new JSONObject(response.body().string()).getString("access_token");
    }
    public static String getTrans(String query,String from,String to) throws IOException {
        MediaType mediaType = MediaType.parse("application/json");
        RequestBody body = RequestBody.create(mediaType, "{\"from\":\""+from+"\",\"to\":\""+to+"\",\"q\":\""+query+"\"}");
        Request request = new Request.Builder()
                .url("https://aip.baidubce.com/rpc/2.0/mt/texttrans/v1?access_token=" + getAccessToken())
                .method("POST", body)
                .addHeader("Content-Type", "application/json")
                .addHeader("Accept", "application/json")
                .build();
        Response response = HTTP_CLIENT.newCall(request).execute();
        String jsonString=response.body().string();
        ObjectMapper objectMapper = new ObjectMapper();
        try {
            // 读取JSON字符串并转换为JsonNode
            JsonNode jsonNode = objectMapper.readTree(jsonString);

            // 提取dst的值
            String dst = jsonNode.path("result").path("trans_result").get(0).path("dst").asText();

            return dst;
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "未知错误";
    }
}

编写对应的调用类

package com.mes.util;

import java.util.HashMap;
import java.util.Map;

public class TransApi {
    private static final String TRANS_API_HOST = "https://fanyi-api.baidu.com/api/trans/vip/translate";

    private String appid;
    private String securityKey;

    public TransApi(String appid, String securityKey) {
        this.appid = appid;
        this.securityKey = securityKey;
    }

    public String getTransResult(String query, String from, String to) {
        Map<String, String> params = buildParams(query, from, to);
        return HttpGet.get(TRANS_API_HOST, params);
    }

    private Map<String, String> buildParams(String query, String from, String to) {
        Map<String, String> params = new HashMap<String, String>();
        params.put("q", query);
        params.put("from", from);
        params.put("to", to);

        params.put("appid", appid);

        // 随机数
        String salt = String.valueOf(System.currentTimeMillis());
        params.put("salt", salt);

        // 签名
        String src = appid + query + salt + securityKey; // 加密前的原文
        params.put("sign", MD5.md5(src));

        return params;
    }

}
