Question

这是我第一次使用Elixir，因此我的第一个应用程序遇到了一些问题。我尝试在curl的帮助下在elixir中实现以下HTTPotion - 等同的请求：

$ curl -s -X GET https://secure.us.playstation.com/playstation/psn/profile/public/userData?onlineId=eagon1337 --referer https://secure.us.playstation.com/logged-in/trophies/public-trophies/ | python -mjson.tool
{
    "avatarUrl": "//static-resource.np.community.playstation.net/avatar_m/3RD/UP40731301009_65ED8105B0C68DC79ABC_M.png",
    "curLevel": "3",
    "handle": "eagon1337",
    "isPlusUser": "1",
    "progress": "15",
    "totalLevel": "",
    "trophies": {
        "bronze": "44",
        "gold": "0",
        "platinum": "0",
        "silver": "1"
    }
}

发送以下请求标头：

> GET /playstation/psn/profile/public/userData?onlineId=eagon1337 HTTP/1.1
> User-Agent: curl/7.30.0
> Host: secure.us.playstation.com
> Accept: */*
> Referer: https://secure.us.playstation.com/logged-in/trophies/public-trophies/

我提出了以下Elixir代码：

defmodule PS4 do
    def helloWorld do

        name = "eagon1337"
        url = "https://secure.us.playstation.com/playstation/psn/profile/public/userData?onlineId=" <> name
        headers = [{"Accept", "*/*"},
                   {"Host", "secure.us.playstation.com"},
                   {"Referer", "https://secure.us.playstation.com/logged-in/trophies/public-trophies/"},
                   {"User-Agent", "curl/7.30.0"}]

        IO.puts "Getting " <> url

        response = HTTPotion.get url, headers: headers

        IO.puts response.body

    end
end

结果是

iex(1)> PS4.helloWorld
Getting https://secure.us.playstation.com/playstation/psn/profile/public/userData?onlineId=eagon1337
** (HTTPotion.HTTPError) req_timedout
    (httpotion) lib/httpotion.ex:209: HTTPotion.handle_response/1
          (ps4) lib/ps4.ex:14: PS4.helloWorld/0

针对http://httpbin.org/get运行整个请求会产生一个非常流畅的标题（另外删除＆＃34;主机＆＃34; -header）：

iex(1)> PS4.helloWorld
Getting httpbin.org/get
{
  "args": {}, 
  "headers": {
    "Accept": "*/*", 
    "Content-Length": "0", 
    "Host": "httpbin.org", 
    "Referer": "https://secure.us.playstation.com/logged-in/trophies/public-trophies/", 
    "User-Agent": "curl/7.30.0"
  }, 
  "origin": "92.77.68.151", 
  "url": "http://httpbin.org/get"
}

:ok

显然，请求的URL需要特定的Referer。但是为什么它与curl一起工作，而不是通过我的Elixir方法？我错过了什么？

这不是直接答案，但使用http://us.playstation.com/代替https://secure.us.playstation.com似乎有效。所以我想知道它可能与ssl部分有关（还没有找到背景）。

HTTPotion.get with＆＃34; Referer＆＃34;在标题中
