x-www-form-urlencoded POST 请求和 net/http 缺少查询参数

Question

我有一个 post 请求 headers 和我想用 net/http 触发的查询参数。请求 returns 200 但响应 body 说：{\"error\":\"invalid_request\",\"error_description\":\"Required query parameter 'grant_type' missing.\"}

这是我调用的完整函数：

def Search.request_oauth_access_token
    require 'net/http'
    uri = URI.parse('https://request.url/oauth2/access_token')
    params = {
        'grant_type' => 'my:grant:type'
    }
    headers = {
    'Authorization' => 'Basic sldhfgKGsdfgGOI23==',
    'Content-Type' => 'application/x-www-form-urlencoded'
    }
    http = Net::HTTP.new(uri.host, uri.port)
    http.use_ssl = true
    request = Net::HTTP::Post.new(uri.request_uri, headers)
    query = URI.encode_www_form_component(params)
    request.body = query
    response = http.request(request)
    p response.body
end

我正在使用 Rails 5.0.2.

Answer 1

解决了。原来我在 params 定义中有一个语法错误。这是定义它的正确方法：

params = {
        grant_type: 'my:grant:type'
    }

然后在请求中：

query = URI.encode_www_form(params)
http.request(request, query)

您还可以将参数语法更改为以下内容：

params = [ [ "param1", "value1" ], [ "param2", "value2" ], [ "param3", "value3" ] ]

Answer 3

最简单的方法是使用 ruby 核心库：

require "uri"
require "net/http"

params = {
          'field1' => 'Nothing is less important',
          'field2' => 'Submit'
}
x = Net::HTTP.post_form(URI.parse('http://www.yahoo.com/web/ch05/formpost.asp'), params)
puts x.body

这拯救了我的一天
