Question

我正在尝试通过R使用Microsoft Cognitive API来处理文本数据。我创建了一个帐户并获得了密钥。代码如下。出于隐私原因，我没有提供密钥。

library(httr)
library(jsonlite)
library(data.table)
library(dplyr)

cogapikey <- "xxxx"
cogapi <- "https://westcentralus.api.cognitive.microsoft.com/text/analytics/v2.0"
text=c("is this english?"
       ,"tak er der mere kage"
       ,"merci beaucoup"
       ,"guten morgen"
       ,"bonjour"
       ,"merde"
       ,"That's terrible"
       ,"R is awesome")
df <- data_frame(id=1:length(text),text)
mydata<- list(documents=df)

# language detection
## construct a request
response <- POST(cogapi,add_headers(`Ocp-Apim-Subscription-Key`=cogapikey),
                 body=toJSON(mydata))
print(response)

打印响应变量后，我得到以下内容。

我想知道是否应该安装额外的必备工具/包？提前谢谢！

Answer 1

这里似乎需要更正端点。它应该是：

cogapi <- "https://westcentralus.api.cognitive.microsoft.com/text/analytics/v2.0/languages"

端点中缺少

/ langauges 。
