I have the following code

conn = Faraday.new(:url => 'http://www.mapquestapi.com') do |faraday|
 faraday.response :logger                  # log requests to STDOUT
 faraday.adapter  Faraday.default_adapter  # make requests with Net::HTTP
 faraday.options.params_encoder = Faraday::FlatParamsEncoder
end

response = conn.get do |req|
   req.url '/geocoding/v1/batch'
   req.params['key'] = 'xxxxx%7xxxxxxxxx%2xxxx%3xxxx-xxxx'
   req.params['location'] = addresses[0]
end

Unfortunately the key param gets encoded as shown in the log in this way key=xxxxx%257xxxxxxxxx%252xxxx%253xxxx-xxxx, causing that the mapquest API respond to with an invalid key (due to the encoding as i tried with postman and it works)

The key param should be send without encoding the %, how can i avoid that this doesnt happen, i haven't found any parameter to change this behavior

Im using Faraday 0.9.0, ruby 2.0. I know i can use the mapquest library that relies on restclient gem but as i ve spent some time coding this it would be nice how to make it work with faraday

这只是部分答案：

可以创建自己的 param_encorder 以避免值字段被转义。这在这里使用（参见方法 build_exclusive_url） ruby​​-2.0.0-p247@zingtech/gems/faraday-0.9.0/lib/faraday/connection.rb

class DoNotEncoder
  def self.encode(params)
    buffer = ''
    params.each do |key, value|
      buffer << "#{key}=#{value}&"
    end
    return buffer.chop
  end
end

conn = Faraday.new(:url => 'http://www.mapquestapi.com') do |faraday|
 faraday.response :logger                  # log requests to STDOUT
 faraday.adapter  Faraday.default_adapter  # make requests with Net::HTTP
 #faraday.options.params_encoder = Faraday::FlatParamsEncoder
 faraday.options.params_encoder = DoNotEncoder
end

但 ！！查询字符串未通过查询文本检查（请参阅 check_query 方法） ruby​​-2.0.0-p247/lib/ruby/2.0.0/uri/generic.rb

我怀疑它由于其他原因而失败。该站点是使用 CSRF 还是您需要捕获 cookie 并将其包含在您的请求中。

如果您需要使用 CSRF，请查看https://gist.github.com/chrisZingel/9042812以获取代码示例。

在你需要法拉第之后添加这个。

module Faraday
  module NestedParamsEncoder
    def self.escape(arg)
      arg
    end
  end
  module FlatParamsEncoder
    def self.escape(arg)
      arg
    end
  end
end
