OAuth protocol - PHP third party login protocol, oauth protocol php third party

MOOC.com Badguy teacher ’s conscience course!

There will always be times when I don’t want to do anything, but today’s days don’t allow personal indulgence. I usually only have these few choices: watch course videos, read books, and read novels. . It seems there is still something that can be done. Among them, watching the course videos is a bit boring, and I have to write code by hand. . It’s good to find a good teacher. Well, let’s study with badguy recently~

Take notes

1. About OAuth

The full name is Open Authorization, open protocol;

is a protocol for PHP to implement third-party login ;

The specific implementation is simplified into three major steps;

But this is what I personally recorded:

2. Before logging in

You need to apply/register to the website that "signed" the agreement (websites that plan to enable third-party login, such as MOOC.com to apply via qq);

Get the website’s unique client_id and client_secret;

3. When logging in

The user clicks "Other Login"——" (The first step of the three steps) The website sends a request to the QQ OAuth server, Request Token URL, and requests the service address, as shown below

https://graph.qq.com/oauth/...

client_id=100490398&...

redirect_uri=http://passport.mukewang.com%...

First there is the oauth identifier, then the client_id, and then the redirect_uri redirect address, which is the return address;

——》(Second step) The user sees the third-party login interface and enters information; here the code will be generated based on the user input, which is invisible to the user and generated directly in the background;

——》(Step 3) The QQ auth server returns the status to the website. For security reasons, there is a User authorization URL. There will be code, client_id, client_secret information for verification. At the same time, the code also has a life cycle. (very short, maybe 5s);

4. After logging in

In addition to realizing third-party login, OAuth also allows authorized websites to perform some functions, such as QQ’s one-click posting space. At this time, there is AccessToken (token), which has a normal life cycle. It will be 7 days; if it is gone, you can log in again to apply. There is also RefreshToken, which will automatically refresh the token;

5. Others

Regarding openness, it can refer to internal openness - for example, Taobao one account, Alipay and other Alibaba series can be used;

Externally-for example, Tencent accounts can be inserted everywhere. .

Last picture

I will continue to learn how to log in with QQ and log in with weibo~

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
