本快速入门介绍了如何使用 Cloud Translation API v2 创建一个程序,以将文本从英语翻译成德语。

须知事项

在运行本快速入门之前,请确保您或您的管理员已满足以下前提条件:

创建用于翻译文本的程序

  1. 在 SAP 系统中,使用事务 SE38 在自定义命名空间中创建可执行程序(例如 Z 或 Y)。

    1. 在 SAP GUI 中,输入事务代码 SE38

    2. 程序字段中,输入程序名称,例如 ZDEMO_TRANSLATE

    3. 点击创建

    4. 指定程序属性:

      1. 标题字段中,输入程序标题,例如 Translate from English to German

      2. 类型字段中,选择 Executable Program

      3. 点击保存

    5. 将程序保存为本地对象

    6. ABAP 编辑器中,添加以下代码:

            READ TABLE lt_translations-translations INTO ls_texts INDEX 1.
            WRITE: / 'Translation Successful'.
            WRITE: / 'Translated Text is: ', ls_texts-translated_text.
          ENDIF.
      
      * close the http connection
                lo_translate->close( ).
      
        CATCH /goog/cx_sdk INTO lo_exception.
      * write code here to handle exceptions
                endtry.
      

      DEMO_TRANSLATE 替换为客户端密钥名称。

  2. SE38 中运行您的应用。如果创建成功,将显示以下输出:

    'Translation Successful'
    'Translated Text is: Die Erde ist der dritte Planet von der Sonne'
