## Crear un middleware { #create-a-middleware }

Para crear un middleware usas el decorador `@app.middleware("http")` encima de una función.

La función middleware recibe:

* La `request`.

		buffer := make([]byte, len(data), 2*len(data))
		copy(buffer, data)

		erasure, err := NewErasure(t.Context(), test.dataBlocks, test.parityBlocks, blockSizeV2)
		if err != nil {
			t.Fatalf("Test %d: failed to create erasure: %v", i, err)
		}
		encoded, err := erasure.EncodeData(t.Context(), buffer)
		if err != nil {
			t.Fatalf("Test %d: failed to encode data: %v", i, err)
		}

		for j := range encoded[:test.missingData] {

For a quick installation, docker-compose reference configs are also available on the [Casdoor Try with Docker](https://casdoor.org/docs/basic/try-with-docker).

### Configure Casdoor

- Go to Applications
  - Create or use an existing Casdoor application
  - Edit the application
    - Copy `Client ID` and `Client secret`
    - Add your redirect url (callback url) to `Redirect URLs`
    - Save

- Go to Users
  - Edit the user

      {{- if and .Values.securityContext.enabled .Values.persistence.enabled }}
      securityContext:
        {{ omit .Values.securityContext "enabled" | toYaml | nindent 8 }}
      {{- end }}
      {{ if .Values.serviceAccount.create }}
      serviceAccountName: {{ .Values.serviceAccount.name }}
      {{- end }}
      containers:
        - name: {{ .Chart.Name }}
          image: "{{ .Values.image.repository }}:{{ .Values.image.tag }}"

### Building a distribution from source

To create a Gradle distribution from the source tree you can run either of the following:

    ./gradlew :distributions-full:binDistributionZip

				}
				got := buf.Bytes()
				if !bytes.Equal(want, got) {
					t.Fatalf("incorrect result: (-got +want)\n%v", bytediff(got, want))
				}
			}
		})
	}
}

func TestPax(t *testing.T) {
	// Create an archive with a large name
	fileinfo, err := os.Stat("testdata/small.txt")
	if err != nil {
		t.Fatal(err)
	}
	hdr, err := FileInfoHeader(fileinfo, "")
	if err != nil {
		t.Fatalf("os.Stat: %v", err)
	}

## Use `CORSMiddleware` { #use-corsmiddleware }

You can configure it in your **FastAPI** application using the `CORSMiddleware`.

* Import `CORSMiddleware`.
* Create a list of allowed origins (as strings).
* Add it as a "middleware" to your **FastAPI** application.

You can also specify whether your backend allows:

* Credentials (Authorization headers, Cookies, etc).

        {{- end }}
        {{- if .Values.customCommandJob.extraVolumes }}
          {{- toYaml .Values.customCommandJob.extraVolumes | nindent 8 }}
        {{- end }}
      {{- if .Values.serviceAccount.create }}
      serviceAccountName: {{ .Values.serviceAccount.name }}
      {{- end }}
      {{- if .Values.policies }}
      initContainers:
        - name: minio-make-policy

---> 100%
```

**Note**: Make sure you put `"fastapi[standard]"` in quotes to ensure it works in all terminals.

## Example

### Create it

Create a file `main.py` with:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}
