Interaction between ios and php mysql

I want to ask,
I want ios and php mysql to interact
That is, after filling out the form on ios, it can be imported into mysql
Currently, it is possible to enter mysql via post (postman)
It’s just that there are difficulties in the next stage
That’s how Can
php mysql be recorded when users log in on ios? Is it enough to just use SESSION?
What kind of API is needed on the ios side?

I have a question. Postman is just a browser plug-in for Chrome used to test server-side APIs. How can I directly interact with MySQL? Regarding your question, the login process needs to be changed.
1. Add authorize table and fields

tokenuser_idexpires_inlogin_atxxxx1userid1timestamp1timestamp2xxxx2userid2timestamp3timestamp42. When logging in, verify the account password. If it passes the verification, set all the user's tokens in the

authorize table to expire, then insert a new record, and then return the token3. Use the Token when requesting the API Request, the server receives the token and checks whether the token exists in the authorize table. If it exists, it determines whether it has expired. If it has not expired, proceed to the next step. If the token does not exist or expires, it returns HTTP 401 status code

Give a token after logging in

First of all, let’s be clear, the interaction between ios and the backend is done through API. . And there will be certain business logic between API and MYSQL. .

The process you mentioned should be like this:
1. Do the login operation on ios and upload the account and password parameters through API POST
2. The background PHP accepts the parameters through POST and compares them with the data in the database for verification
3. Pass Afterwards, you can generate a session and then store the session in the database and return the session to the ios client. 4. The ios client packages the session into the API request. 5. The php background accepts any request and checks whether the session exists in the session table. If yes, the request is legal, if not, the request is illegal

Another: The expiration mechanism is not considered. . Simple process

The easiest way is to use the web session mechanism, with minimal or even no changes to the existing PHP code.

Just imagine the API interface for iOS as an ajax request on the web page. PHP returns json data which is more convenient for the client to parse.

For example:
The current PHP login may be like this: the user submits the user name and password through the form of the web page, PHP queries mysql to verify the user information, if it can log in, set the session and cookie, mark the user as logged in, and then PHP returns redirect Response (pre-login page or home page).

If it is ajax login, the last step returns json data, such as

return json_encode(['code' => '1', 'msg' => 'Login successful!']);

The above is the simplest example of php+mysql login. If you don’t understand it, search and learn “php ajax login” first. If you know what is mentioned above, you don’t actually need to learn the iOS part, you already know it. The APIs used by iOS are the same as those used by Ajax. The iOS client uses HTTP client (AFNetworking recommended), requests a URL, and PHP returns json data. Regarding cookies, sessions, etc., the system has automatically processed them, and the iOS client does not need to handle them manually.

Api returns JSON only to facilitate client parsing. You can also return xml, text, html and other similar formats, as long as you negotiate with the client.
