# 机器翻译2.0(niutrans) WebAPI 接口调用示例
# 运行前：请先填写Appid、APIKey、APISecret
# 运行方法：直接运行 main 即可
# 结果： 控制台输出结果信息
#
# 1.接口文档（必看）：https://www.xfyun.cn/doc/nlp/niutrans/API.html
# 2.错误码链接：https://www.xfyun.cn/document/error-code （错误码code为5位数字）
# 3.个性化翻译术语自定义：
#   登陆开放平台 https://www.xfyun.cn/
#   在控制台--机器翻译(niutrans)--自定义翻译处
#   上传自定义翻译文件（打开上传或更新窗口，可下载示例文件）
