哪个是最适合流媒体和文件下载的?
Which one is best for streaming and file downloads?
请提供示例.
推荐答案send_data(_data_, options = {}) send_file(_path_, options = {})
此处的主要区别在于,您使用 send_data 传递DATA(二进制代码或其他代码),或使用 send_file 传递文件PATH.
Main difference here is that you pass DATA (binary code or whatever) with send_data or file PATH with send_file.
因此,您可以生成一些数据并将其作为内联文本或附件发送,而无需通过 send_data 在服务器上生成文件.或者,您可以使用 send_file
So you can generate some data and send it as an inline text or as an attachment without generating file on your server via send_data. Or you can send ready file with send_file
data = "Hello World!" send_data( data, :filename => "my_file.txt" )或
data = "Hello World!" file = "my_file.txt" File.open(file, "w"){ |f| f << data } send_file( file )出于性能考虑,最好只生成一次文件,然后根据需要发送多次.因此send_file会更合适.
For perfomance it is better to generate file once and then send it as many times as you want. So send_file will fit better.
就流媒体而言,据我所知,这两种方法都使用相同的选项和设置,因此您可以使用X-Send或其他任何方法.
For streaming, as far as I understand, both of this methods use the same bunch of options and settings, so you can use X-Send or whatever.
UPD
发送数据并保存文件:
data = "Hello World!" file = "my_file.txt" File.open(file, "w"){ |f| f << data } send_data( data )更多推荐
Ruby on Rails中的send
