Hi:
I am currently developing IOS mobile devices to read the JSON data of the Google IOT API, but I have encountered authorization verification, server token and other errors during development.
I am currently developing IOS mobile devices to read the JSON data of the Google IOT API, but I have encountered authorization verification, server token and other errors during development.
1, I follow the official REST documentation provided by Google and the browser access API, and the IOS side reads JSON, still wrong;
2, the related services and client keys are also bound on the GCP console platform;
3, also created the Compute Engine API virtual machine, but do not know how to access the final JSON data;
4, you can see this is the information about my console;
5, I want to know, IOS mobile access to the Google API, this OAuth2.0 certification must pass? Is it necessary to request any authorization from Google for any API? I don't have my own server domain name. How do I fill out an authorized domain name and pass it?
6, readers and Google api official supporters, can you give me a whole idea process, how can I get Google API and JSON;
