网络HTTP unescapes字符？

Question

Ruby Net HTTP unescape字符（例如龅到龅）？我使用HTTParty发送请求龅，但请求服务器上的请求参数显示为龅。

Answer 1

Net :: HTTP不做任何转换或解码。这只是一个移动数据的管道。

如果您在服务器端看到转换后的字符，那么您可以在看到它们之前更改它们。

这显示了Net :: HTTP发送的内容。在test.rb：

#!/usr/bin/env ruby 
require 'ap' 
require 'sinatra' 

post '/' do 
    t = %w[text/css text/html application/javascript] 
    request.body.rewind # in case someone already read it 
    puts "request.accept    #{ request.accept    }" # ['text/html', '*/*'] 
    puts "request.accept? 'text/xml' #{ request.accept? 'text/xml' }" # true 
    puts "request.preferred_type(t) #{ request.preferred_type(t) }" # 'text/html' 
    puts "request.body    #{ request.body    }" # request body sent by the client (see below) 
    puts "request.scheme    #{ request.scheme    }" # "http" 
    puts "request.script_name  #{ request.script_name  }" # "/example" 
    puts "request.path_info   #{ request.path_info   }" # "/foo" 
    puts "request.port    #{ request.port    }" # 80 
    puts "request.request_method  #{ request.request_method  }" # "GET" 
    puts "request.query_string  #{ request.query_string  }" # "" 
    puts "request.content_length  #{ request.content_length  }" # length of request.body 
    puts "request.media_type   #{ request.media_type   }" # media type of request.body 
    puts "request.host    #{ request.host    }" # "example.com" 
    puts "request.get?    #{ request.get?    }" # true (similar methods for other verbs) 
    puts "request.form_data?   #{ request.form_data?   }" # false 
    puts "request['SOME_HEADER']  #{ request['SOME_HEADER']  }" # value of SOME_HEADER header 
    puts "request.referrer   #{ request.referrer   }" # the referrer of the client or '/' 
    puts "request.user_agent   #{ request.user_agent   }" # user agent (used by :agent condition) 
    puts "request.cookies   #{ request.cookies   }" # hash of browser cookies 
    puts "request.xhr?    #{ request.xhr?    }" # is this an ajax request? 
    puts "request.url    #{ request.url    }" # "http://example.com/example/foo" 
    puts "request.path    #{ request.path    }" # "/example/foo" 
    puts "request.ip     #{ request.ip     }" # client IP address 
    puts "request.secure?   #{ request.secure?   }" # false (would be true over ssl) 
    puts "request.forwarded?   #{ request.forwarded?   }" # true (if running behind a reverse proxy) 

    ap request.env["rack.request.form_hash"] # raw env hash handed in by Rack 
end 

在test2.rb：

#!/usr/bin/env ruby 

require 'net/http' 

uri = URI('http://0.0.0.0:4567/') 
res = Net::HTTP.post_form(uri, 'q' => '龅') 

那些保存到相应的文件，然后运行第一：

ruby test.rb 
== Sinatra/1.3.2 has taken the stage on 4567 for development with backup from Thin 
>> Thin web server (v1.3.1 codename Triple Espresso) 
>> Maximum connections set to 1024 
>> Listening on 0.0.0.0:4567, CTRL+C to stop 

其次是第二。你应该看到类似的东西：

request.accept    ["*/*"] 
request.accept? 'text/xml' text/xml 
request.preferred_type(t) text/css 
request.body    #<StringIO:0x000001017187c8> 
request.scheme    http 
request.script_name   
request.path_info  /
request.port    4567 
request.request_method  POST 
request.query_string  
request.content_length  16 
request.media_type   application/x-www-form-urlencoded 
request.host    0.0.0.0 
request.get?    false 
request.form_data?   true 
request['SOME_HEADER']  
request.referrer   
request.user_agent   Ruby 
request.cookies   {} 
request.xhr?    false 
request.url    http://0.0.0.0:4567/ 
request.path    /
request.ip     127.0.0.1 
request.secure?   false 
request.forwarded?   false 
{ 
    "q" => "&#40837;" 
} 

注意最后一行。这就是Net :: HTTP作为q参数发送到POST请求的原因。
