我的问题与
How to rescue timeout issues (Ruby,Rails)有关.
以下是从超时中解救的常用方法：
def action # Post using Net::HTTP rescue Timeout::Error => e # Do something end
我想确定在尝试连接到主机时是否引发了异常,或者在尝试从主机读取时是否引发了异常.这可能吗？
解决方法
这是解决方案(在Ben的修复之后)：
require "net/http"
http = Net::HTTP.new("example.com")
http.open_timeout = 2
http.read_timeout = 3
begin
http.start
begin
http.request_get("/whatever?") do |res|
res.read_body
end
rescue Timeout::Error
puts "Timeout due to reading"
end
rescue Timeout::Error
puts "Timeout due to connecting"
end
