Question

我正在尝试将ruby用于网站的api。说明是发送带有标头的GET请求。这些是来自网站的说明和他们提供的示例php代码。我要计算HMAC哈希并将其包含在apisign标题下。

$apikey='xxx';
$apisecret='xxx';
$nonce=time();
$uri='https://bittrex.com/api/v1.1/market/getopenorders?apikey='.$apikey.'&nonce='.$nonce;
$sign=hash_hmac('sha512',$uri,$apisecret);
$ch = curl_init($uri);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('apisign:'.$sign));
$execResult = curl_exec($ch);
$obj = json_decode($execResult);

我只是在命令提示符下使用安装在windows上的ruby的.rb文件。我在ruby文件中使用net / http。如何发送带标题的GET请求并打印响应？

Answer 1

根据问题的建议使用net/http。

参考文献：

Net::HTTP https://ruby-doc.org/stdlib-2.4.1/libdoc/net/http/rdoc/Net/HTTP.html
Net::HTTP::get https://ruby-doc.org/stdlib-2.4.1/libdoc/net/http/rdoc/Net/HTTP.html#method-c-get
设置标题：https://ruby-doc.org/stdlib-2.4.1/libdoc/net/http/rdoc/Net/HTTP.html#class-Net::HTTP-label-Setting+Headers
Net::HTTP::Get https://ruby-doc.org/stdlib-2.4.1/libdoc/net/http/rdoc/Net/HTTP/Get.html
Net::HTTPGenericRequest https://ruby-doc.org/stdlib-2.4.1/libdoc/net/http/rdoc/Net/HTTPGenericRequest.html和Net::HTTPHeader https://ruby-doc.org/stdlib-2.4.1/libdoc/net/http/rdoc/Net/HTTPHeader.html（适用于Net::HTTP::Get可以调用的方法）

所以，例如：

require 'net/http'    

uri = URI("http://www.ruby-lang.org")
req = Net::HTTP::Get.new(uri)
req['some_header'] = "some_val"

res = Net::HTTP.start(uri.hostname, uri.port) {|http|
  http.request(req)
}

puts res.body # <!DOCTYPE html> ... </html> => nil

注意：如果您的res ponse HTTP结果状态301（永久移动），请参阅Ruby Net::HTTP - following 301 redirects

安装httparty gem，它使请求变得更容易，然后在您的脚本中

require 'httparty'

url = 'http://someexample.com'
headers = {
  key1: 'value1',
  key2: 'value2'
}

response = HTTParty.get(url, headers: headers)
puts response.body

然后运行您的.rb文件..
