推荐答案

除非您至少上传文件两次，或者在文件中包含检查值(SHA哈希值或类似值)例如)你不能.

否则，该文件必须具有完整性控制.

您可以使用FTP来做到这一点，但我想您正在谈论的是标准上传.

Unless you either upload the file at least twice, or include a checking value with the file (an SHA hash value or similar for example) you can''t.

The file would have to have integrity control in it, otherwise.

You can do it with FTP, but I imagine you are talking about a standard upload.
