I have problem with assigning curl as variable and assign curl's output to variable:
#get results url, format json
URL=$(curl https://api.apifier.com/xy)
#jq is a cli json interpreter
#resultUrl contains the final URL which we want download
OK= "$URL" | jq '.resultsUrl'
#api probably is running
sleep 5
curl "$OK"
Maybe it is trivial, but I don't know where is the problem.
My guess is:
jq '.resultsUrl'
outputs the field resultsUrl with quotes, so curl does not process it correctly. Furthermore, $URL | ... does not work, you would have to use echo or curl directly.
Try
OK=$(curl -s https://api.apifier.com/v1/xHbBnrZ9rxF4CdKjo/crawlers/Example_Alcatraz_Cruises/execute?token=nJ9ohCHZPaJRFEb7nFqtzm76u | jq -r '.resultsUrl')
curl -s "$OK"
which results for me in
[{ "id": 2, "url": "https://www.alcatrazcruises.com/SearchEventDaySpan.aspx?date=02-25-2016&selected=", "loadedUrl": "https://www.alcatrazcruises.com/SearchEventDaySpan.aspx?date=02-25-2016&selected=", "requestedAt": "2016-02-25T23:24:52.611Z", "loadingStartedAt": "2016-02-25T23:24:54.663Z", "loadingFinishedAt": "2016-02-25T23:24:55.642Z", "loadErrorCode": null, "pageFunctionStartedAt": "2016-02-25T23:24:55.839Z", "pageFunctionFinishedAt": "2016-02-25T23:24:55.841Z", "uniqueKey": "https://www.alcatrazcruises.com/SearchEventDaySpan.aspx?date=02-25-2016&selected=", "type": "UserEnqueued", ...
This should be what you expect.
However, sometimes the first API call yields an error:
{
"type": "ALREADY_RUNNING",
"message": "The act is already running and concurrent execution is not allowed"
}
so resultsURL will be null, you will have to handle this error case.
https://api.apifier.com/v1/execs/yxcxycxycycx/resultsYour line
OK= "$URL" | jq '.resultsURL'
sets the environment variable OK to an empty string, then tries to execute "$URL" as a command and pipe its output to jq. If you want to setOK to the result of a command, you have to use $OK=(...), just like you did when setting URL. The correct syntax is:
OK=$(echo "$URL" | jq '.resultsURL')
And to remove the quotes from the output of .jq, you can do:
OK=$(echo "$URL" | jq '.resultsURL' | tr -d '"')
jq -r option removes quotes from strings, obviating the need for tr -d '"'.
OK= "$URL" | jq '.resultsUrl'toOK=$(echo $URL | jq '.resultsUrl'). You should probably check that OK isn't null before you attempt to curl it.URL, but not use that same syntax to setOK?
