Save the file with the name of the array key - bash

Question

I have a script that downloads files. The links are consist of two-part: one in the cur(the stable one) and the second one in the Associative array.
So I want to have a script that downloads a file and given a name like a key from my arrey
declare -A metricssArray
metricssArray[key1]=some link
metricssArray[key2]=some link
curl --location --request GET 'First part of link'+${metricssArray[key1]} --output example.csv
I know that will give a file name "example.csv"
-output examle.csv
But I need to have a file with the name key1.csv as my key from the array
curl --location --request GET 'First part of link'+${metricssArray[key1]} --output example.csv
When I change ${metricssArray[key2]} or key3 in curl the file should be downloaded with key2.csv name
Or maybe I going to download all of them and I need to understand with file belongs to with link/array key
for key in "${!metricssArray[#]}"; do
# ........^..............^ iterates over the keys
curl --location \
--request GET \
--output "$key".csv \
-u name:password \
'firs part of the link'+${metricssArray[$#]}
done
I have tried to put -u after the link but I get a file and inside 403 status code(

I'm not entirely certain what the question is.
If you're asking about how to iterate over the associative array, you can do this:
declare -A metricssArray
metricssArray[key1]=some link
metricssArray[key2]=some link
for key in "${!metricssArray[#]}"; do
# ........^..............^ iterates over the keys
curl --location \
--request GET \
--output "$key".csv \
'First part of link'+${metricssArray[$key]}
done
To build the URL, you might want:
# the array notation does not require line continuations
curl_opts=(
--location
--request GET
--user "username:password"
)
url_root=http://example.com/start/of/path
for key in "${!metricssArray[#]}"; do
url="${url_root}/${metricssArray[$key]}"
curl "${curl_opts[#]}" --output "$key".csv "$url"
done
