我的批量请求有类似的回复，但我在收到每个批次kind时遇到问题。如何检索每个批次＆＃39; kind ??

修改

我使用Googl的批量请求获得类似的回复。

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"]

batch_decoded_body给出了上述回复。变量OR中的batch_decoded表示我可以使用其中任何一个。

Answer 1

您需要分别处理批次中的每个条目：

将批次分隔为条目：

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

第一个条目不是一个条目，而是一个标题，所以你可以摆脱它：
```
entries.shift
```

对于每个条目解析为JSON，从{开始：

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

所有在一起：

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

您应该查看json库。例如：

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来阅读您的回复（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

如果您的回答与上面的回答完全相同，比如存储在一个名为str的变量中，并且您希望将这些类型作为字符串数组进行排序，则可以执行以下操作：

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

从ruby中的批处理请求中检索信息
