The key to dealing with API authentication is to understand and use the authentication method correctly. 1. APIKey is the simplest authentication method, usually placed in the request header or URL parameters; 2. BasicAuth uses username and password for Base64 encoding transmission, which is suitable for internal systems; 3. OAuth2 needs to obtain the token first through client_id and client_secret, and then bring the BearerToken in the request header; 4. In order to deal with the token expiration, the token management class can be encapsulated and automatically refreshed the token; in short, selecting the appropriate method according to the document and safely storing the key information is the key.

To view Git commit history, use the gitlog command. 1. The basic usage is gitlog, which can display the submission hash, author, date and submission information; 2. Use gitlog--oneline to obtain a concise view; 3. Filter by author or submission information through --author and --grep; 4. Add -p to view code changes, --stat to view change statistics; 5. Use --graph and --all to view branch history, or use visualization tools such as GitKraken and VSCode.

Setting the style of links you have visited can improve the user experience, especially in content-intensive websites to help users navigate better. 1. Use CSS's: visited pseudo-class to define the style of the visited link, such as color changes; 2. Note that the browser only allows modification of some attributes due to privacy restrictions; 3. The color selection should be coordinated with the overall style to avoid abruptness; 4. The mobile terminal may not display this effect, and it is recommended to combine it with other visual prompts such as icon auxiliary logos.

To test the API, you need to use Python's Requests library. The steps are to install the library, send requests, verify responses, set timeouts and retry. First, install the library through pipinstallrequests; then use requests.get() or requests.post() and other methods to send GET or POST requests; then check response.status_code and response.json() to ensure that the return result is in compliance with expectations; finally, add timeout parameters to set the timeout time, and combine the retrying library to achieve automatic retry to enhance stability.

HTML5, CSS and JavaScript should be efficiently combined with semantic tags, reasonable loading order and decoupling design. 1. Use HTML5 semantic tags, such as improving structural clarity and maintainability, which is conducive to SEO and barrier-free access; 2. CSS should be placed in, use external files and split by module to avoid inline styles and delayed loading problems; 3. JavaScript is recommended to be introduced in front, and use defer or async to load asynchronously to avoid blocking rendering; 4. Reduce strong dependence between the three, drive behavior through data-* attributes and class name control status, and improve collaboration efficiency through unified naming specifications. These methods can effectively optimize page performance and collaborate with teams.

In Python, variables defined inside a function are local variables and are only valid within the function; externally defined are global variables that can be read anywhere. 1. Local variables are destroyed as the function is executed; 2. The function can access global variables but cannot be modified directly, so the global keyword is required; 3. If you want to modify outer function variables in nested functions, you need to use the nonlocal keyword; 4. Variables with the same name do not affect each other in different scopes; 5. Global must be declared when modifying global variables, otherwise UnboundLocalError error will be raised. Understanding these rules helps avoid bugs and write more reliable functions.

To delete a Git branch, first make sure it has been merged or no retention is required. Use gitbranch-d to delete the local merged branch. If you need to force delete unmerged branches, use the -D parameter. Remote branch deletion uses the gitpushorigin-deletebranch-name command, and can synchronize other people's local repositories through gitfetch-prune. 1. To delete the local branch, you need to confirm whether it has been merged; 2. To delete the remote branch, you need to use the --delete parameter; 3. After deletion, you should verify whether the branch is successfully removed; 4. Communicate with the team to avoid accidentally deleting shared branches; 5. Clean useless branches regularly to keep the warehouse clean.

AMA in the currency circle is the abbreviation of Ask Me Anything, which is literally translated as "ask me any questions". This is a form of interaction between project parties and community members. Project teams usually broadcast live on specific platforms, such as Telegram groups, Discord servers, or via Twitter Spaces, to open questions to participants. Community members can take this opportunity to directly raise questions about any aspects such as technology, economic model, marketing promotion, roadmap, etc. to the core members of the project.
