API Calls, JSON Processing and Web Data Collection
A Chinese Python archive for requests, response checks, JSON parsing, data cleaning, pagination and saving results, with explicit privacy, frequency and authorization boundaries.
What this archive is for
This Chinese tutorial follows a complete data-processing chain: send a request, inspect the response, parse JSON, clean fields, handle pagination and save results. It is a learning snapshot rather than a promise that an example endpoint, dependency or page structure will remain stable. Treat each example as a small testable program.
A reproducible request workflow
Start with a saved, anonymized response or a mock server. Check status code, encoding, headers and the shape of nested fields before writing a parser. Turn missing values, duplicate records, time formats and pagination into explicit rules, then assert record counts and key fields before storing output. Add timeouts, bounded retries and a low request rate only within an allowed scope.
Privacy and access boundaries
Keep API keys, cookies, personal data and full responses out of repositories and shared logs. An HTTP response does not by itself grant permission for bulk collection. Review service terms, robots guidance, copyright, privacy requirements and frequency limits; prefer an official API or data you own. When a response changes, pause writes and compare the schema before updating historical data.
Maintenance note
This page was reviewed on 2026-08-23 against the catalog metadata, request workflow and privacy notes. Confirm current dependencies, source permissions and service limits before running an example.
Save to your cloud drive
Save the complete collection first so files remain together and are easier to access across devices.

API and JSON practice with a low-frequency test workflow
Begin with a mock or saved response, make the parser observable and only use live data inside a clearly permitted scope.
Before you start
- Prepare a ZIP extractor, Python and an isolated environment with the listed dependencies.
- Read the project license, service terms and any source-specific access rules.
- Use anonymized responses or your own test data before connecting a live source.
Quick start
- 01
Inspect the project structure
Read the README, license, dependency files and configuration examples and identify entry points, parameters and output paths.
- 02
Parse one saved response
Check status, encoding, nested fields, missing keys and pagination using a mock or anonymized JSON response before making live requests.
- 03
Add cleaning and assertions
Define types, null handling, duplicates, timestamps and expected record counts, then fail visibly when the schema changes.
- 04
Run at a controlled rate
Set timeouts, bounded retries and an interval, record source, time and version and expand the sample only when the scope allows it.
Usage tips
- Store secrets in environment variables, redact logs and remove cookies, keys and personal data before sharing code.
- Check service terms, rate limits, privacy and copyright; accessible data is not automatically permitted for bulk collection.
- Keep raw responses, cleaned output and parser revisions separate so a schema change can be compared and rolled back.
Troubleshooting and uninstall
What should happen after a 403, 429 or empty response?
Stop increasing request frequency, check permissions, terms and parameters and use an official interface or contact the data provider.
Why did JSON parsing report a missing field?
Save the actual response, verify status, encoding, nesting and pagination and handle version differences with explicit validation.
Frequently asked questions
What does this API and JSON archive teach?
It covers request handling, response checks, JSON parsing, field cleaning, pagination and saving structured results.
Can the sample collect any website?
No. Check authorization, service terms, rate limits, privacy and copyright first, and prefer an official API or your own test data.
How should API keys and cookies be stored?
Use environment variables or an ignored local configuration file, redact logs and remove secrets and personal data before sharing.
What should happen when an interface changes?
Pause writes, save the changed response, compare its schema with the expected contract and update the parser with tests before resuming.
