net/http: HTTP/1.x 传输连接断开：http: ContentLength=2514

Question

我正在尝试将 nodejs 应用程序转换为 Go。在这里，我试图将文件上传到 B2。但我越来越 Post "https://pod-XX.backblaze.com/b2api/v2/b2_upload_file/WERTGVWGTE/cSEREf": net/http: HTTP/1.x transport connection broken: http: ContentLength=3312 with Body length 0。这是我的代码：

// open file

    file, err := os.Open(location)

    if err != nil {

        log.Fatal(err)

        return "", err

    }

    defer file.Close()

    // create sha1 hash of file

    hash := sha1.New()

    if _, err := io.Copy(hash, file); err != nil {

        log.Fatal(err)

        return "", err

    }

    sha1Sum := hex.EncodeToString(hash.Sum(nil))

    // http client

    client := http.Client{}

    req, _ := http.NewRequest("POST", b2.UploadUrl, file)

    contentLength, _ := file.Stat()

    

    req.ContentLength = contentLength.Size()  // without this, its throwing map[code:bad_request message:Missing header: Content-Length status:400]

    req.Header.Set("Content-Type", "application/octet-stream")

    req.Header.Set("Authorization", b2.AuthorizationToken)

    req.Header.Set("X-Bz-File-Name", name)

    req.Header.Set("X-Bz-Content-Sha1", sha1Sum)

    res , errr := client.Do(req)

    if errr != nil {

        log.Fatalln(errr)

        return "", errr

    }

仅供参考，这是完美运行的nodejs代码：

const file = await fs.readFile(location);

    const sha1 = crypto.createHash('sha1').update(file).digest("hex");

    const config = {

        headers: {

            'Authorization': auth_token,

            'X-Bz-File-Name': final_name,

            'Content-Type': 'b2/x-auto',

            'X-Bz-Content-Sha1': sha1

        }

    };

    let response = await axios.post(upload_url, file, config);

    return response.data['fileId'];

您在这里使用了文件：if _, err := io.Copy(hash, file); err != nil {        log.Fatal(err)        return "", err    }使用func (*File) Seek或加载文件到内存。
