当cURL正常工作时，从Go代码中使用API​​时出现401错误

Question

I've written a simple go code that, sends a GET request to an API and in response I receive a 401 error. However when I use cURL, I receive the desired response. I also get expected response using API Tester . So, I believe, there has to be something wrong with my code and that, I'm unable to find out.

Below is my Go code, that, responds with 401 Error

func main() {
    clusterId := os.Getenv("CLUSTER_ID")
    apiUrl := "https://api.qubole.com/api/v1.3/clusters/"+clusterId+"/state"
    auth_token := os.Getenv("X_AUTH_TOKEN")
    fmt.Println("URL - ",apiUrl)
    req, err := http.NewRequest("GET", apiUrl, nil)
    if(err != nil){
        fmt.Println("ERROR in getting rest response",err)
    }
    req.Header.Set("X-Auth-Token", auth_token)
    req.Header.Set("Content-Type", "application/json")
    req.Header.Set("Accept", "application/json")

    res, err := http.DefaultClient.Do(req)
    if(err != nil){
       fmt.Println("Error: No response received", err)
    }
    defer res.Body.Close()
    //print raw response body for debugging purposes
    body, _ := ioutil.ReadAll(res.Body)
    fmt.Println(string(body))
}

Extract of Response/Error I get, is as follows:

URL -  https://api.qubole.com/api/v1.3/clusters/presto-bi/state
{"error":{"error_code":401,"error_message":"Invalid Token"}}

Now, Following is the cURL command that, returns me the desired response

curl -X GET -H "X-AUTH-TOKEN:$X_AUTH_TOKEN" -H "Content-Type: application/json" -H "Accept: application/json" "https://us.qubole.com/api/v1.3/clusters/presto-bi/state"

below is the stdout I receive, which is as expected: {"state":"DOWN"}%

Answer 1

I'm just guessing here without enough information. I'm assuming clusterId := os.Getenv("CLUSTER_ID") is presto-bi . If that is the case, then you are just missing "clusters" in your path.

apiUrl := "https://api.qubole.com/api/v1.3/clusters/"+clusterId+"/state"

Also, shouldn't you use us.qubole.com/api instead of api.qubole.com ?

Answer 2

Need check api hostname at golang and curl again. Thanks!

The error is because, the documentation of API provider states the host WRONG ( API Documentation ) . But, since the portal login is us.qubole.com ( PORTAL Login URL ), cURL command was written considering that in mind.
