英文:
net/http: HTTP/1.x transport connection broken: http: ContentLength=2514 with Body length 0
问题
我正在尝试将一个Node.js应用程序转换为Go。在这里，我正在尝试将文件上传到B2。但是我得到了一个错误信息：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。以下是我的代码：
// 打开文件
file, err := os.Open(location)
if err != nil {
log.Fatal(err)
return "", err
}
defer file.Close()
// 创建文件的SHA1哈希值
hash := sha1.New()
if _, err := io.Copy(hash, file); err != nil {
log.Fatal(err)
return "", err
}
sha1Sum := hex.EncodeToString(hash.Sum(nil))
// 创建HTTP客户端
client := http.Client{}
req, _ := http.NewRequest("POST", b2.UploadUrl, file)
contentLength, _ := file.Stat()
req.ContentLength = contentLength.Size() // 如果没有这一行，会抛出map[code:bad_request message:Missing header: Content-Length status:400]错误
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，以下是完全正常工作的Node.js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'];
希望对你有所帮助！如果你有任何其他问题，请随时问我。

I am trying to convert a nodejs app to Go. Here I am trying to upload a file to B2. But I am getting 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 . Here is my code:
// 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
}
Just for reference here is the nodejs code that is perfectly working:
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'];

得分: 1
你在这里使用了文件：
if _, err := io.Copy(hash, file); err != nil {
log.Fatal(err)
return "", err
}
可以使用func (*File) Seek或将文件加载到内存中。
英文:
You have consumed file here:
if _, err := io.Copy(hash, file); err != nil {
log.Fatal(err)
return "", err
}
Use func (*File) Seek or load file to memory.
