您正在寻找 --data-binary 参数:

curl -i -X POST host:port/post-file 
  -H "Content-Type: text/xml" 
  --data-binary "@path/to/file"

在上面的例子中，-i 打印出所有的标题以便你可以看到发生了什么，并且 -X POST 明确表示这是一个帖子.这两者都可以安全地省略而不会改变线路上的行为.文件路径需要以 @ 符号开头，以便 curl 知道从文件中读取.

In the example above, -i prints out all the headers so that you can see what's going on, and -X POST makes it explicit that this is a post. Both of these can be safely omitted without changing the behaviour on the wire. The path to the file needs to be preceded by an @ symbol, so curl knows to read from a file.
