Question

在法拉第中苦苦挣扎。我想知道我实际发送到服务器的内容。我得到了响应正文，但没有访问请求正文。我发现有一种request.env方法，但我无法以某种方式访问那里的身体。

那会怎么样？

conn = Faraday.new(:url => 'http://sushi.com') do |faraday|
  faraday.request  :url_encoded             # form-encode POST params
  faraday.response :logger                  # log requests to STDOUT
  faraday.adapter  Faraday.default_adapter  # make requests with Net::HTTP
end

data = conn.post do |req|
  req.url '/nigiri'
  req.headers['Content-Type'] = 'application/json'
  req.body = '{ "name": "Unagi" }'
end

# how do I get access to the request body here?

我尝试做的是：

[4] pry(main)> request.env.request

=> #<struct Faraday::RequestOptions
 params_encoder=nil,
 proxy=nil,
 bind=nil,
 timeout=nil,
 open_timeout=nil,
 boundary=nil,
 oauth=nil>

但我无法进入尸体。有什么想法吗？

谢谢！

您可以尝试为此目的实现中间件。只是为了让你快速了解你可以做些什么来实现这个目标（可能有一种更简单的方法，但我真的不知道，我想因为你指定了请求体，所以没有真正需要捕获它，因为你应该已经拥有这个可用）。

require 'faraday'

class RequestBody < Faraday::Middleware
  def call(env)
    request_body = env.body

    @app.call(env).on_complete do |response|
      response[:request_body] = request_body
    end
  end
end

conn = Faraday.new(:url => 'http://sushi.com') do |faraday|
  faraday.use RequestBody
  faraday.adapter Faraday.default_adapter
end

data = conn.post do |req|
  req.url '/nigiri'
  req.headers['Content-Type'] = 'application/json'
  req.headers['foo'] = 'bar'
  req.body = '{ "name": "Unagi" }'
end

# 2.2.2 > data.env[:request_body]
#  => "{ \"name\": \"Unagi\" }"
# 2.2.2 > data.env.request_headers
#  => {"User-Agent"=>"Faraday v0.9.2", "Content-Type"=>"application/json", "foo"=>"bar"}
# 2.2.2 > data.body
#  => "<!DOCTYPE HTML PUBLIC \"-//IETF//DTD HTML 2.0//EN\">\n<html><head>\n<title>301 Moved Permanently</title>\n</head><body>\n<h1>Moved Permanently</h1>\n<p>The document has moved <a href=\"http://www.sushi.com/index.php/nigiri\">here</a>.</p>\n<hr>\n<address>Apache/2.4.10 (Unix) OpenSSL/1.0.1e-fips mod_bwlimited/1.4 PHP/5.4.32 Server at sushi.com Port 80</address>\n</body></html>\n"

法拉第可以访问请求参数
