AzureCognitive R 包翻译服务 returns http 400: "body of request is not valid JSON."

AzureCognitive R package translate service returns http 400: "body of request is not valid JSON."

我尝试使用 AzureCognitive R 包使翻译服务正常工作,但出现 HTTP 400 错误,我似乎无法修复它。

有人可以看看这是错误还是我做错了什么?

按照此 example,您可以将正文传递为 body=list(list(text = "Hello, what is your name"")),

call_cognitive_endpoint(endpoint = endp,
                        operation = "translate",
                        options = list('api-version' = "3.0",
                                       'from' = 'en',
                                       'to' = 'dk'),
                        body = list(list(text = "Hello, what is your name")),
                        http_verb = "POST")
