Question

Ruby的全新。我引用了Curb文档并尝试使用安全令牌在curl中提交请求。以下是传统请求中标题的3个部分：

我-安全令牌
1234567890
website.com

如何构建Curb以提交姓名，值和评论，如上所示？

我从以下开始：

c = Curl::Easy.new("http://website.com") do |curl| 
  curl.headers["Name"] = "My-Security-Token"
  curl.headers["Value"] = "1234567890"
  curl.headers["Comment"] = "website.com"
  curl.verbose = true
end

c.perform

Answer 1

以下是我传统请求的标题的3个部分


我-安全令牌

1234567890

website.com

标题包含名称/值对，因此您的描述没有任何意义。

看起来您的标题名称应为：

 My-Security-Token

它的价值应该是：

1234567890

要制作GET request（您没有提及您正在制作的请求类型）并指定该标题，您可以执行以下操作：

require 'curb'

http = Curl.get("http://website.com/") do |http| 
  http.headers["My-Security-Token"] = "1234567890"
end

puts http.body_str[0..249]  #Output the first 250 characters of the response

如果您想使用详细模式，它将显示实际的请求和响应，您可以这样做：

require 'curb'

c = Curl::Easy.new("http://www.google.com/") do |curl| 
  curl.headers["My-Security-Token"] = "1234567890"
  curl.verbose = true
end

c.perform  #Outputs the request and the response
puts c.body_str[0..249]  #body_str => the body of the response

输出：

* About to connect() to www.google.com port 80 (#0)
*   Trying 74.125.28.147... * Connected to www.google.com (74.125.28.147) port 80 (#0)

如果您确实希望自定义标头为：

Name: My-Security-Token
Value: 1234567890
Comment: website.com

...然后你可以这样做：

require 'curb'

c = Curl::Easy.new("http://www.google.com/") do |curl| 
  curl.headers["Name"] = "My-Security-Token"
  curl.headers["Value"] = "1234567890"
  curl.headers["Comment"] = "website.com"
  curl.verbose = true
end

c.perform
puts c.body_str[0..249]

...将生成如下输出：

* About to connect() to www.google.com port 80 (#0)
*   Trying 74.125.28.105... * Connected to www.google.com (74.125.28.105) port 80 (#0)
> GET / HTTP/1.1
Host: www.google.com
Accept: */*
Name: My-Security-Token   #HERE ARE YOUR HEADERS
Value: 1234567890         #HERE
Comment: website.com      #HERE
...
...

如果上面没有任何内容符合您的要求，那么如何发布您的实际＆＃34;传统＆＃34;请求？如果您不知道如何操作，请搜索谷歌。

如何构建Curb以提交姓名，值和评论，如上所示？

第二个想法，看起来Name，Value和Comment是单个http头的组件：

通过围绕着，可以在一些HTTP头字段中包含注释带括号的注释文本。评论仅允许在包含“注释”的字段作为其字段值定义的一部分在所有其他字段中，括号被视为字段的一部分值。

如果是这种情况，您可以像这样创建自定义标题：

require 'curb'

c = Curl::Easy.new("http://www.google.com/") do |curl| 
  curl.headers["My-Security-Token"] = "1234567890 (website.com)"
  curl.verbose = true
end

c.perform  #Outputs the request and the response
puts c.body_str[0..249]  #body_str => the body of the response

--output:--
* About to connect() to www.google.com port 80 (#0)
*   Trying 74.125.28.104... * Connected to www.google.com (74.125.28.104) port 80 (#0)
> GET / HTTP/1.1
Host: www.google.com
Accept: */*
My-Security-Token: 1234567890 (website.com)  #***YOUR CUSTOM HEADER****
...
...
