谷歌翻译 API 之间的区别

我正在构建一个基于 Google 翻译的开源 Chrome 扩展（here https://github.com/MagTun/Customizable-Google-Translate-Chrome-extension/blob/master/README.md).

我已经阅读了有关 Google 翻译 API 的其他问题（例如one https://stackoverflow.com/questions/43155233/google-translate-api-paid-vs-google-translate-api-free和这个one https://stackoverflow.com/q/8085743/3154274）但我仍然没有答案。 我发现了几个谷歌翻译的网址，如下所示：

似乎所有 URL 都是 3 部分的不同组合：

• 基本网址：

  • translate.googleapis.com/translate_a/
  • https://translate.google.com/translate_a/
  • https://clients5.google.com/translate_a/

• 之后的第一个参数translate_a/： 任何一个single or t

• 的客户可以是gtx, t or dict-chrome-ex [or 显然任何ID https://stackoverflow.com/questions/43155233/google-translate-api-paid-vs-google-translate-api-free]

到目前为止，我已经看到返回的 JSON 存在差异。 这返回这个 json：

[[["père","father",null,null,1]
]
,null,"en"]

虽然这返回这个 json：

{"sentences":[{"trans":"père","orig":"father","backend":1},{"src_translit":"ˈfäT͟Hər"}],"dict":[{"pos":"noun","terms":["père"],"entry":[{"word":"père","reverse_translation":["father","dad","parent","papa"],"score":0.70910621,"previous_word":"le","gender":1}],"base_form":"father","pos_enum":1},{"pos":"verb","terms":["engendrer","concevoir"],"entry":[{"word":"engendrer","reverse_translation":["generate","engender","give rise to","beget","breed","father"],"synset_id":[52561],"score":0.00017133754},{"word":"concevoir","reverse_translation":["design","conceive","devise","plan","form","father"],"synset_id":[52561],"score":4.8327973e-05}],"base_form":"father","pos_enum":2}],"src":"en","alternative_translations":[{"src_phrase":"father","alternative":[{"word_postproc":"père","score":1000,"has_preceding_space":true,"attach_to_next_token":false}],"srcunicodeoffsets":[{"begin":0,"end":6}],"raw_src_segment":"father","start_pos":0,"end_pos":0}],"confidence":1,"ld_result":{"srclangs":["en"],"srclangs_confidences":[1],"extended_srclangs":["en"]},"query_inflections":[{"written_form":"father","features":{"number":2}},{"written_form":"fathers","features":{"number":1}}],"target_inflections":[{"written_form":"père","features":{"gender":1,"number":2}},{"written_form":"pères","features":{"gender":1,"number":1}},{"written_form":"père","features":{"number":2}},{"written_form":"pères","features":{"number":1}}]}

所以我的问题是上面给出的不同组合之间有什么（除了这个）差异。 在这种情况下我应该使用其中之一而不是另一个（返回的 JSON 除外）。是否有折旧或支持更多请求的产品？

对于查询的含义：https://stackoverflow.com/a/29537590/3154274 https://stackoverflow.com/a/29537590/3154274

关于您的实际问题，除了您所说的之外，我不确定是否存在任何有意义的差异，并且很难确定它们中的任何一个是否以及何时被弃用。

鉴于这些 API 没有记录，并且似乎不适合以这种方式使用，我认为不应考虑将它们中的任何一个用于开发实际应用程序。

但是，为了解决您寻找免费的人类语言翻译 A​​PI 的问题，我建议Azure 文本翻译 API https://azure.microsoft.com/en-us/pricing/details/cognitive-services/translator-text-api/它提供了翻译每月 200 万个字符作为其免费套餐的一部分。

对于您的特定用例，我认为可能存在大量重复翻译，我认为缓存结果将为减少使用量提供显着的好处。
