## 处理 JWT 令牌

导入已安装的模块。

创建用于 JWT 令牌签名的随机密钥。

使用以下命令，生成安全的随机密钥：

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

然后，把生成的密钥复制到变量**SECRET_KEY**，注意，不要使用本例所示的密钥。

创建指定 JWT 令牌签名算法的变量 **ALGORITHM**，本例中的值为 `"HS256"`。

		if err != nil {
			writeErrorResponse(ctx, w, toAPIError(ctx, err), r.URL)
			return
		}

		// Set the correct hex md5sum for the fan-out stream.
		fanOutOpts.MD5Hex = hex.EncodeToString(md5w.Sum(nil))

		concurrentSize := 100
		if runtime.GOMAXPROCS(0) < concurrentSize {
			concurrentSize = runtime.GOMAXPROCS(0)
		}

// along with this program.  If not, see <http://www.gnu.org/licenses/>.

package cmd

import (
	"bufio"
	"context"
	"encoding/binary"
	"encoding/gob"
	"encoding/hex"
	"errors"
	"fmt"
	"io"
	"net/http"
	"os/user"
	"path"
	"runtime"
	"runtime/debug"
	"strconv"
	"strings"
	"sync"
	"time"

Import the modules installed.

Create a random secret key that will be used to sign the JWT tokens.

To generate a secure random secret key use the command:

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

And copy the output to the variable `SECRET_KEY` (don't use the one in the example).

        " user-agent:OkHttp" +
        "]}",
    )
  }

  private fun bodyToHex(body: RequestBody): String {
    val buffer = Buffer()
    body.writeTo(buffer)
    return buffer.readByteString().hex()
  }
