使用来自文件的发布数据向 cURL 发送请求
问题描述：
我需要从命令行通过 cURL 发出 POST 请求.此请求的数据位于文件中.我知道通过 PUT 这可以通过 --upload-file 选项来完成.
I need to make a POST request via cURL from the command line. Data for this request is located in a file. I know that via PUT this could be done with the --upload-file option.
curl host:port/post-file -H "Content-Type: text/xml" --data "contents_of_file"
答
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.
