问题描述
我有一个登录表单的页面.登录后，有一些重定向.第一个看起来像这样:
I have a page that logs into a form. After logging in there are a few redirects. The first one looks like this:
#<Mechanize::File:0x1f4ff23 @filename="MYL.html", @code="200", @response={"cache-control"=>"no-cache=\"set-cookie\"", "content-length"=>"114", "set-cookie"=>"JSESSIONID=GdJnPVnhtN91KZfQPc3QzM1NLCyWDsnyvpGg8LL0Knnz3RgqxLFs!1803804592!-2134626567; path=/; secure, COOKIE_TEST=Aslyn; secure", "x-powered-by"=>"Servlet/2.4 JSP/2.0"}, @body="\r\n<html>\r\n <head>\r\n <meta http-equiv=\"refresh\" content=\"0;URL=MYL?Select=OK&StateName=38\">\r\n </head>\r\n</html>", @uri=#<URI::HTTPS:0x16e1eff URL:https://www.manageyourloans.com/MYL?StateName=global_CALMLandingPage&GUID=D1704621-1994-E076-460A-10B2B682B960>>
所以当我在这里执行page.class时，我会得到
so when I do a page.class here I get
Mechanize::File
如何将其转换为Mechanize::Page?

为了更好地解释，我的原始消息中的代码存储在页面中.
To better explain I have the code in my original message is stored in page.
当我执行page.class时，我得到了Mechanize :: File
When I do page.class I get Mechanize::File
因此，我在上面摘录了您的代码:
So then I excute your code above:
agent = Mechanize.new
agent.post_connect_hooks << lambda {|http| http[:response].content_type = 'text/html'}
所以我这样做: agent.get(page.uri.to_s) 或事件，请尝试使用任何网址agent.get(" https://www.manageyourloans.com/MYL " )我收到一个错误: ArgumentError:参数数量错误(4个代表1个)
So I do this: agent.get(page.uri.to_s) or event try with any url agent.get("https://www.manageyourloans.com/MYL")I get an error: ArgumentError: wrong number of arguments (4 for 1)
我什至尝试过:
agent = Mechanize.new { |a|
a.post_connect_hooks << lambda { |_,_,response,_|
if response.content_type.nil? || response.content_type.empty?
response.content_type = 'text/html'
end
}
}
我的问题是一旦执行此操作，如何将上一页转换为Mechanize :: Page?
My question is once I do this, how do I convert the previous page into a Mechanize::Page?
推荐答案
您可以通过将文件对象中包含的主体作为对象的主体传递给Mechanize :: File，将其转换为Mechanize :: Page.新页面:
You can convert from a Mechanize::File to a Mechanize::Page by taking the body contained in the file object and passing that in as the body of a new page:
irb(main):001:0> require 'mechanize'
true
irb(main):002:0> file = Mechanize::File.new(URI.parse('http://foo.com'),nil,File.read('foo.html'))
#<Mechanize::File:0x100ef0190
@full_path = false,
attr_accessor :body = "<html><body>foo</body></html>\n",
attr_accessor :code = nil,
attr_accessor :filename = "index.html",
attr_accessor :response = {},
attr_accessor :uri = #<URI::HTTP:0x100ef02d0
attr_accessor :fragment = nil,
attr_accessor :host = "foo.com",
attr_accessor :opaque = nil,
attr_accessor :password = nil,
attr_accessor :path = "",
attr_accessor :port = 80,
attr_accessor :query = nil,
attr_accessor :registry = nil,
attr_accessor :scheme = "http",
attr_accessor :user = nil,
attr_reader :parser = nil

首先，我创建了一个伪造的Mechanize :: File对象，只是为了让它跟随示例代码.您可以在:body中看到它读取的文件的内容.
First, I created a fake Mechanize::File object just to have one for the example code to follow. You can see the content of the file it read in the :body.
Mechanize在无法确定真正的内容类型是什么时会创建一个Mechanize :: File对象.
Mechanize creates a Mechanize::File object when it can't figure out what the true content-type is.
irb(main):003:0> page = Mechanize::Page.new(URI.parse('http://foo.com'),nil,file.body)
#<Mechanize::Page:0x100ed5e30
@full_path = false,
@meta_content_type = nil,
attr_accessor :body = "<html><body>foo</body></html>\n",
attr_accessor :code = nil,
attr_accessor :encoding = nil,
attr_accessor :filename = "index.html",
attr_accessor :mech = nil,
attr_accessor :response = {
"content-type" => "text/html"
},
attr_accessor :uri = #<URI::HTTP:0x100ed5ed0
attr_accessor :fragment = nil,
attr_accessor :host = "foo.com",
attr_accessor :opaque = nil,
attr_accessor :password = nil,
attr_accessor :path = "",
attr_accessor :port = 80,
attr_accessor :query = nil,
attr_accessor :registry = nil,
attr_accessor :scheme = "http",
attr_accessor :user = nil,
attr_reader :parser = nil
>,
attr_reader :bases = nil,
attr_reader :encodings = [
[0] nil,
[1] "US-ASCII"
],
attr_reader :forms = nil,
attr_reader :frames = nil,
attr_reader :iframes = nil,
attr_reader :labels = nil,
attr_reader :labels_hash = nil,
attr_reader :links = nil,
attr_reader :meta_refresh = nil,
attr_reader :parser = nil,
attr_reader :title = nil
>
irb(main):004:0> page.class
Mechanize::Page < Mechanize::File
只需传递文件对象的主体，然后让Mechanize转换为您应该知道的样子即可.
Just pass in the body of the file object and let Mechanize convert to what you know it should be.
