AzureCognitive R 包翻译服务返回 http 400：“请求正文不是有效的 JSON。”

Question

我尝试使用 AzureCognitive R 包让翻译服务正常工作，但我收到 HTTP 400 错误，我似乎无法修复它。

# Initial setup
# I've already did the create login
# az <- AzureRMR::create_azure_login(tenant = "<tenant>")

az <- AzureRMR::get_azure_login()
sub <- az$get_subscription(id = "<id>")
rg <- sub$get_resource_group("<resource-group>")

# retrieve it
cogsvc <- rg$get_cognitive_service(name = "<name>")

# getting the endpoint from the resource object
endp <- cogsvc$get_endpoint()

# This is where it fails

call_cognitive_endpoint(endpoint = endp,
                        operation = "translate",
                        options = list('api-version' = "3.0",
                                       'from' = 'en',
                                       'to' = 'dk'),
                        body = "[{'Text':'Hello, what is your name?'}]",
                        http_verb = "POST")


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

谁能看看这是一个错误还是我做错了什么？

根据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")
