我正在嘗試將 nodejs 應(yīng)用程序轉(zhuǎn)換為 Go。在這里，我試圖將文件上傳到 B2。但我越來越 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。這是我的代碼：// 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    }僅供參考，這是完美運(yùn)行的nodejs代碼：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'];
