httr POST authentication error

问题

I am trying to structure a POST json request using httr. The API documentation proposes the following the CURL request:

curl -X POST -H "Authorization:Token XXXXXXXXX" -H "Content-Type: application/json" --data "{\"texts\":[\"A simple string\"]}" https://api.uclassify.com/v1/uclassify/topics/classify

My R httr implementation is the following:

POST("https://api.uclassify.com/v1/uClassify/Topics/classify", 
    encode="json",
    add_headers('Authorization:Token'="XXXXXXXXX"),
    body=("A simple string"))

But I received a 401 error message which indicates that my authentication failed. Any suggestion on how I can implement the CURL request on httr?

回答1:

Just in case it can help somebody else, the below code works for me: POST("https://api.uclassify.com/v1/uClassify/Topics/classify", encode="json", add_headers(Authorization = "Token XXXXXXXXX"), body = "{\"texts\":[\"A simple string\"]}")
