我有一个API，在其中我使用lz4帧压缩来压缩字符串，并在响应中将结果发送到前端。在JavaScript中，我获取该API并使用pierrec的lz4包解压缩数据，当时我得到了无效的幻数错误。有人能帮我吗？
后端

package main

import (
    "bytes"
    "fmt"
    "io"

    "github.com/pierrec/lz4"

    "github.com/gin-gonic/gin"
)

var fileContent = `CompressBlock compresses the source buffer starting at soffet into the destination one. This is the fast version of LZ4 compression and also the default one. The size of the compressed data is returned. If it is 0 and no error, then the data is incompressible. An error is returned if the destination buffer is too small.`

func main() {
    router := gin.Default()

    // Define the API endpoint
    router.POST("/api/endpoint", func(c *gin.Context) {
        toCompress := []byte(fileContent)
        // compressed := make([]byte, len(toCompress))

        result, err := compress(toCompress)
        if err != nil {
            fmt.Println(err)
        }

        c.JSON(200, gin.H{"result": result})
    })

    // Start the server
    router.Run(":8000")
}

func compress(in []byte) ([]byte, error) {
    r := bytes.NewReader(in)
    w := &bytes.Buffer{}
    zw := lz4.NewWriter(w)
    _, err := io.Copy(zw, r)
    if err != nil {
        return nil, err
    }
    // Closing is very important
    if err := zw.Close(); err != nil {
        return nil, err
    }
    return w.Bytes(), nil
}

字符串
前端

import fetch from 'node-fetch';
import LZ4 from 'lz4';

const apiUrl = 'http://localhost:8000/api/endpoint';

const postData = async () => {
  try {
    const response = await fetch(apiUrl, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({}),
    });

    if (!response.ok) {
      throw new Error('Request failed with status ' + response.status);
    }
    const result = await response.json();
    // const decoded = base64ToArrayBuffer(result.result);
    const buffer = Buffer.from(result.result);
    const decompressed = LZ4.decode(buffer);
    const decodedBuffer = Buffer.from(decompressed);
    console.log(decodedBuffer.toString());
  } catch (error) {
    console.error(error);
  }
};

postData();
