Oauth2.0开发 为何子要提交access_token或者还有一两个其他固定参数就能识别用户身份
Oauth2.0开发 为什么子要提交access_token或者还有一两个其他固定参数就能识别用户身份?
小弟最近要开发对APP请求的验证接口(服务端的,不是客户端哦),一直没明白,为什么通过Oauth协议流程获取到access_token之后,接下来的操作(对用户数据的增删改查)都只需要提交一个access_token,或者还有OpenID和APPKey(这些参数的有效期都是比较长,一般几天)就能判断用户的身份进行增删改查操作,小弟不明白,万一这几个参数泄露或被窃取了,那他人(第三方)不就可以通过提交这几个参数修改用户数据了吗?小弟第一次进行类似的开发,求大家指点下,如果能有源代码就更好的,在此先谢过各位~~

当用户通过oauth授权给第三方,第三方得到access_token之后,平台就和用户没有直接的关系了,剩下的操作都是服务器通过access_token的权限和平台进行交互。如果说access_token泄露,说明说第三方的服务器已经不安全了。在平台方能做的验证只能确保说,这个操作请求是由access_token授予的第三方应用发出,这种验证可以通过绑定应用的域名,IP,回调地址来实现

SQL IF statements are used to conditionally execute SQL statements, with the syntax as: IF (condition) THEN {statement} ELSE {statement} END IF;. The condition can be any valid SQL expression, and if the condition is true, execute the THEN clause; if the condition is false, execute the ELSE clause. IF statements can be nested, allowing for more complex conditional checks.

The advantage of multithreading is that it can improve performance and resource utilization, especially for processing large amounts of data or performing time-consuming operations. It allows multiple tasks to be performed simultaneously, improving efficiency. However, too many threads can lead to performance degradation, so you need to carefully select the number of threads based on the number of CPU cores and task characteristics. In addition, multi-threaded programming involves challenges such as deadlock and race conditions, which need to be solved using synchronization mechanisms, and requires solid knowledge of concurrent programming, weighing the pros and cons and using them with caution.

The main reasons why you cannot log in to MySQL as root are permission problems, configuration file errors, password inconsistent, socket file problems, or firewall interception. The solution includes: check whether the bind-address parameter in the configuration file is configured correctly. Check whether the root user permissions have been modified or deleted and reset. Verify that the password is accurate, including case and special characters. Check socket file permission settings and paths. Check that the firewall blocks connections to the MySQL server.

How to configure Zend in Apache? The steps to configure Zend Framework in an Apache Web Server are as follows: Install Zend Framework and extract it into the Web Server directory. Create a .htaccess file. Create the Zend application directory and add the index.php file. Configure the Zend application (application.ini). Restart the Apache Web server.

Methods to solve the cross-domain problem of Vue Axios include: Configuring the CORS header on the server side using the Axios proxy using JSONP using WebSocket using the CORS plug-in

The key to PHPMyAdmin security defense strategy is: 1. Use the latest version of PHPMyAdmin and regularly update PHP and MySQL; 2. Strictly control access rights, use .htaccess or web server access control; 3. Enable strong password and two-factor authentication; 4. Back up the database regularly; 5. Carefully check the configuration files to avoid exposing sensitive information; 6. Use Web Application Firewall (WAF); 7. Carry out security audits. These measures can effectively reduce the security risks caused by PHPMyAdmin due to improper configuration, over-old version or environmental security risks, and ensure the security of the database.

This article describes how to effectively monitor the SSL performance of Nginx servers on Debian systems. We will use NginxExporter to export Nginx status data to Prometheus and then visually display it through Grafana. Step 1: Configuring Nginx First, we need to enable the stub_status module in the Nginx configuration file to obtain the status information of Nginx. Add the following snippet in your Nginx configuration file (usually located in /etc/nginx/nginx.conf or its include file): location/nginx_status{stub_status

Apache server is a powerful web server software that acts as a bridge between browsers and website servers. 1. It handles HTTP requests and returns web page content based on requests; 2. Modular design allows extended functions, such as support for SSL encryption and dynamic web pages; 3. Configuration files (such as virtual host configurations) need to be carefully set to avoid security vulnerabilities, and optimize performance parameters, such as thread count and timeout time, in order to build high-performance and secure web applications.
