* Configure any required permissions and roles using dependencies.
* Never store plaintext passwords, only password hashes.
* Implement and use well-known cryptographic tools, like Passlib and JWT tokens, etc.
* Add more granular permission controls with OAuth2 scopes where needed.
* ...etc.

# Зависимости

**FastAPI** имеет очень мощную и интуитивную систему **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>**.

Она проектировалась таким образом, чтобы быть простой в использовании и облегчить любому разработчику интеграцию других компонентов с **FastAPI**.

## Что такое "Dependency Injection" (инъекция зависимости)

- **দ্রুত কোড করা**:বৈশিষ্ট্য তৈরির গতি ২০০% থেকে ৩০০% বৃদ্ধি করে৷ \*
- **স্বল্প bugs**: মানুব (ডেভেলপার) সৃষ্ট ত্রুটির প্রায় ৪০% হ্রাস করে। \*
- **স্বজ্ঞাত**: দুর্দান্ত এডিটর সাহায্য <abbr title="also known as auto-complete, autocompletion, IntelliSense">Completion</abbr> নামেও পরিচিত। দ্রুত ডিবাগ করা যায়।

- **সহজ**: এটি এমন ভাবে সজানো হয়েছে যেন নির্দেশিকা নথি পড়ে সহজে শেখা এবং ব্যবহার করা যায়।

    * Validation even for deeply nested JSON objects.
* <abbr title="also known as: serialization, parsing, marshalling">Conversion</abbr> of input data: coming from the network to Python data and types. Reading from:
    * JSON.
    * Path parameters.
    * Query parameters.
    * Cookies.
    * Headers.
    * Forms.
    * Files.

But a variable like `user-agent` is invalid in Python.

So, by default, `Header` will convert the parameter names characters from underscore (`_`) to hyphen (`-`) to extract and document the headers.

Also, HTTP headers are case-insensitive, so, you can declare them with standard Python style (also known as "snake_case").
