### 编辑器支持

整个框架都被设计得易于使用且直观，所有的决定都在开发之前就在多个编辑器上进行了测试，来确保最佳的开发体验。

    val encoded = CertificateAdapters.certificate.toDer(decoded)

    assertThat(encoded).isEqualTo(certificateByteString)
  }

  @Test

    val privateKeyInfoByteString =

## 安装 `PyJWT`

安装 `PyJWT`，在 Python 中生成和校验 JWT 令牌：

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info | "说明"

如果您打算使用类似 RSA 或 ECDSA 的数字签名算法，您应该安装加密库依赖项 `pyjwt[crypto]`。

您可以在 <a href="https://pyjwt.readthedocs.io/en/latest/installation.html" class="external-link" target="_blank">PyJWT Installation docs</a> 获得更多信息。

///

<div class="termy">

```console
$ pip install -r requirements.txt
---> 100%
Successfully installed fastapi pydantic
```

</div>

/// info

There are other formats and tools to define and install package dependencies.

///

### Create the **FastAPI** Code

* Create an `app` directory and enter it.
* Create an empty file `__init__.py`.

	c.Assert(response.StatusCode, http.StatusOK)

	// retrieve the info of last modification time of the object from the response header.
	lastModified := response.Header.Get("Last-Modified")
	// Parse it into time.Time structure.
	t, err := time.Parse(http.TimeFormat, lastModified)
	c.Assert(err, nil)

	// make HTTP request to obtain object info.

You and your crush eat the burgers and have a nice time. ✨
