这是我第一次使用 Elixir
,所以我的第一个应用程序遇到了一些问题。我正在尝试在 curl
的帮助下在 elixir 中实现以下 HTTPotion
-request 的等效项:
$ 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"
}
}
它发送以下请求头:
> 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/
我想出了以下 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
这导致
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平滑的 header (额外删除了“主机” 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 需要一个特定的 Referer。但是为什么它可以与 curl 一起使用,而不是通过我的 Elixir 方法呢?我错过了什么?
最佳答案
这不是直接的答案,但使用 http://us.playstation.com/
而不是 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)。
关于curl - 带有 "Referer"的 HTTPotion.get header ,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/31214270/
