Figuring out a new API.
I’m trying to call an endpoint and populate a JSON file with the data. I see the following output:
admin@server:~$ curl -H "Authorization: Bearer <NOT DISPLAYED FOR THIS POST>" -o /home/admin/result.json https://www.endpoint.com/manage/query/run?id=55408&cmd=service&output=json
[1] 14493
[2] 14494
admin@server:~$ % Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0
It hangs here seemingly indefinitely until I hit enter and then the below displays
[1]- Done curl -H "Authorization: Bearer <NOT DISPLAYED FOR THIS POST>" -o /home/admin/result.json https://www.endpoint.com/manage/query/run?id=55408
[2]+ Done cmd=service
No error messages, and no data in result.json. Calling the same cURL command without the -o option also returns the same results, when normally I would expect to see the data pop up in my terminal. If I visit the endpoint URL in browser (auth token can be a URL parameter as well for this API), I see the exact data I want to download. Changing the Auth Token makes no difference in the output.
I know every API is different, and there are a hundred different troubleshooting questions I haven’t addressed in this post, but has anyone experienced this type of output before with a cURL command? I’ve never seen this behavior before.
The API is for Slate, an SIS for universities, if that helps. Thank you!
>Solution :
Your URL has a & in it which is a bash syntax character to run a task in the background. Quote the URL to prevent it being interpreted as syntax.
admin@server:~$ curl -H "Authorization: Bearer <NOT DISPLAYED FOR THIS POST>" -o /home/admin/result.json "https://www.endpoint.com/manage/query/run?id=55408&cmd=service&output=json"
