## FAQs

### How does ``MinIO`` manage dependencies?

``MinIO`` uses `go mod` to manage its dependencies.

- Run `go get foo/bar` in the source folder to add the dependency to `go.mod` file.

To remove a dependency

- Edit your code and remove the import reference.

GOLANGCI = $(GOLANGCI_DIR)/golangci-lint

all: build

checks: ## check dependencies
	@echo "Checking dependencies"
	@(env bash $(PWD)/buildscripts/checkdeps.sh)

help: ## print this help
	@grep -E '^[a-zA-Z_-]+:.*?## .*$$' Makefile | awk 'BEGIN {FS = ":.*?## "}; {printf "\033[36m%-40s\033[0m %s\n", $$1, $$2}'

getdeps: ## fetch necessary dependencies
	@mkdir -p ${GOPATH}/bin

每个身份验证应用都会采用不同方式会命名流，以便融合入自己的品牌。

但归根结底，它们使用的都是 OAuth2 标准。

///

**FastAPI** 的 `fastapi.security.oauth2` 里包含了所有 OAuth2 身份验证流工具。

## 装饰器 `dependencies` 中的 `Security`

# Test dependencies for pip tests
grpcio ~= 1.42.0
portpicker ~= 1.5.2
scipy ~= 1.7.3
jax ~= 0.2.26

## Update the dependencies

Now we are going to update our dependencies.

We want to get the `current_user` *only* if this user is active.

So, we create an additional dependency `get_current_active_user` that in turn uses `get_current_user` as a dependency.

Both of these dependencies will just return an HTTP error if the user doesn't exist, or if is inactive.

#!/usr/bin/env bash

_init() {

	shopt -s extglob

	## Minimum required versions for build dependencies
	GIT_VERSION="1.0"
	GO_VERSION="1.16"
	OSX_VERSION="10.8"
	KNAME=$(uname -s)
	ARCH=$(uname -m)
	case "${KNAME}" in
	SunOS)
		ARCH=$(isainfo -k)
		;;
	esac
}

## FIXME:
## In OSX, 'readlink -f' option does not exist, hence
## we have our own readlink -f behavior here.

### Dependencies

The same applies for [dependencies](tutorial/dependencies/index.md){.internal-link target=_blank}. If a dependency is a standard `def` function instead of `async def`, it is run in the external threadpool.

### Sub-dependencies
