Implementation Reference

• src/index.ts:56-98 (handler)

  The main handler function for the 'copyI18n' tool. It downloads i18n files for Chinese and optionally English, saves them temporarily, copies to src/lang/source, and cleans up.

  async ({ rootPath }) => {
    let langArr = [{ name: "ZhCn", value: 1, filePath: "ZhCn.js" }];
    // 目前只有企业版需要英文文件
    if (port === "5500") {
      langArr.push({ name: "EnUs", value: 2, filePath: "EnUs.js" });
    }
    // 获取工作区根路径
    // const rootPath = process.cwd();
    let result = "";
    try {
      for (let lang of langArr) {
        const langTargetPath = path.join(
          rootPath,
          "src/lang/source",
          lang.filePath
        );
        const tempFilePath = path.join(rootPath, lang.filePath);
        // 创建一个写入流
        const writer = fs.createWriteStream(tempFilePath);
        const res = await downFile(lang.value);
        res.data.pipe(writer);
        await new Promise<void>((resolve, reject) => {
          writer.on("finish", () => resolve());
          writer.on("error", (err) => reject(err));
        });
        fs.copyFileSync(tempFilePath, langTargetPath);
        fs.unlinkSync(tempFilePath);
        console.log(`${lang.name}文件复制成功`);
        result = `${tempFilePath}文件复制成功`;
      }
    } catch (error) {
      console.log("文件复制失败", error);
      result = `文件复制失败${error},${rootPath},`;
    }
    return {
      content: [
        {
          type: "text",
          text: result,
        },
      ],
    };
  }

• src/index.ts:53-55 (schema)

  Input schema for the copyI18n tool, requiring a 'rootPath' string parameter.

  {
    rootPath: z.string(),
  },

• src/index.ts:51-99 (registration)

  Registration of the 'copyI18n' tool using server.tool(), including schema and inline handler.

  server.tool(
    "copyI18n",
    {
      rootPath: z.string(),
    },
    async ({ rootPath }) => {
      let langArr = [{ name: "ZhCn", value: 1, filePath: "ZhCn.js" }];
      // 目前只有企业版需要英文文件
      if (port === "5500") {
        langArr.push({ name: "EnUs", value: 2, filePath: "EnUs.js" });
      }
      // 获取工作区根路径
      // const rootPath = process.cwd();
      let result = "";
      try {
        for (let lang of langArr) {
          const langTargetPath = path.join(
            rootPath,
            "src/lang/source",
            lang.filePath
          );
          const tempFilePath = path.join(rootPath, lang.filePath);
          // 创建一个写入流
          const writer = fs.createWriteStream(tempFilePath);
          const res = await downFile(lang.value);
          res.data.pipe(writer);
          await new Promise<void>((resolve, reject) => {
            writer.on("finish", () => resolve());
            writer.on("error", (err) => reject(err));
          });
          fs.copyFileSync(tempFilePath, langTargetPath);
          fs.unlinkSync(tempFilePath);
          console.log(`${lang.name}文件复制成功`);
          result = `${tempFilePath}文件复制成功`;
        }
      } catch (error) {
        console.log("文件复制失败", error);
        result = `文件复制失败${error},${rootPath},`;
      }
      return {
        content: [
          {
            type: "text",
            text: result,
          },
        ],
      };
    }
  );

• src/api.ts:36-50 (helper)

  Helper function 'downFile' used by copyI18n to download the i18n JSON file as a stream for a given language ID.

  async function downFile(language: number) {
    const streamConfig = {
      baseURL: `${url}`,
      headers: {
        Cookie: token,
      },
      responseType: "stream" as const
    };
    const res = await http.get(
      `/MultiLanguageResource/DownWebJson?language=${language}`,
      null,
      streamConfig
    );
    return res;
  }
