正在ruby中从批处理请求检索信息

这是一个示例批处理请求响应。

我的批处理请求有一个类似的响应，但我很难获得每个批的kind。如何检索每个批次的"kind"？？

编辑

我使用Googl的Batch Request得到了类似的响应。

gclient = Google::APIClient.new(....)
batch = Google::APIClient::BatchRequest.new
batch.add(list_salesman_one).add(list_salesman_two)
batch = gclient.execute(batch).to_json
batch_decoded = ActiveSupport::JSON.decode(batch)  OR    batch_decoded = JSON.parse(batch)
batch_decoded_body = batch_decoded["response"]["body"]

其中batch_decoded_body给出了上面的响应。变量batch_decoded中的OR表示我可以使用任意一个。

Answer 1

您需要分别处理批次中的每个条目：

1. 单独批次到条目：

   entries = batch_decoded_body.strip.split(/^--.*/)
   

2. 第一个条目实际上不是一个条目，而是一个标题，所以你可以去掉它：

   entries.shift
   

3. 对于每个条目，解析为JSON，从{:开始

   entries.map { |entry| JSON.parse entry[/{.*/m] }
   

总之：

entries = batch_decoded_body.strip.split(/^--.*/)
entries.shift
entries.map { |entry| JSON.parse(entry[/{.*/m])['kind'] }
# => ["glass#timelineItem", "glass#timelineItem", "glass#timelineItem"] 
entries.map { |entry| JSON.parse(entry[/{.*/m])['items'].map { |item| item['ipAddress'] } }
# => [["IP_ADDRESS_HERE"], ["IP_ADDRESS_HERE"]] 

Answer 2

您可能应该查看json库。示例：

require 'json'
require 'open-uri'
request = open('http://ip.jsontest.com')
response = JSON.parse(request.read)
response["ip"]

您可以使用JSON.parse读取您的响应(我假设它在一个名为response的变量中(：

require 'json'
response_json = JSON.parse(response)
response_json['kind']

Answer 3

如果你的响应与上面的完全一样，比如存储在一个名为str的变量中，并且你想以字符串数组的形式导出种类，你可以执行以下操作：

arr = str.scan(/{.*?kind.*?}/m)
puts arr
