仅在多个get参数请求中返回第一个参数

I have the following api curl request:

curl --request GET http://127.0.0.1/juris?d=11111&a=22222

Inside my http handler function which has the arguments: w http.ResponseWriter,r *http.Request i have the code:

defer r.Body.Close()
keys,ok := r.URL.Query()["d"]   
if !ok{
 respondWithError(w,http.StatusBadRequest,"InvalidQuery")
 return
}
dnisQuery := string(keys[0])
akeys,aok := r.URL.Query()["a"]     
if !aok{
 respondWithError(w,http.StatusBadRequest,"InvalidQuery")
 return
}
aniQuery := string(akeys[0])

It validates and passes the correct value for the first query parameter d but it fails for the second parameter a with an InvalidQuery

Not sure what im doing incorrectly.

    If you issue

    curl --request GET http://127.0.0.1/juris?d=11111&a=22222
    

    the shell will see

    curl --request GET http://127.0.0.1/juris?d=11111 & a=22222
    

    and run the first command as a background job, that's why the a part was ignored. (It actually resulted in the shell setting the variable a to 22222.) To get it to work, you have to escape your URL:

    curl --request GET 'http://127.0.0.1/juris?d=11111&a=22222'
