將XML響應讀入Rails

Question

我的控制器中有一個URL，當它被調用時返回一個XML響應。比方說，答案看起來像這樣;

<?xml version="1.0" encoding="UTF-8"?> 
<AutoCreate> 
<Response> 
    <Status>YES</Status> 
    <name>JOSEPH</name> 
    <location>HOME</location> 
</Response> 
</AutoCreate> 

我如何可以讀取這些值status，name和location到變量在我的控制器，並使用它們。

預先感謝您。

Answer 1

如果respose.body的值是;

<?xml version="1.0" encoding="UTF-8"?> 
<AutoCreate> 
<Response> 
    <Status>YES </Status> 
    <name> JOSEPH </name> 
    <location> HOME </location> 
</Response> 
</AutoCreate> 

然後我認爲這應該沒問題。

require ‘active_support’ 
result = Hash.from_xml(response.body) 

然後;

result.status == "YES" 

這項工作？

Answer 2

你可以試試這個，

response_json = Hash.from_xml(response).to_json 

Answer 3

您可以使用https://github.com/alsemyonov/xommelier

feed = Xommelier::Atom::Feed.parse(open('spec/fixtures/feed.atom.xml')) 
puts feed.id, feed.title, feed.updated 

feed.entries do |entry| 
    puts feed.id, feed.title, feed.published, feed.updated 
    puts feed.content || feed.summary 
end 

Answer 4

因此，繼承人爲Rails 5的更新，

如果您收到一個XML響應頭會'application/xml' 您使用數據訪問

#read the response and create a Hash from the XML 
response = Hash.from_xml(request.body.read) 

#read value from the Hash 
status = response["AutoCreate"]["Response"]["Status"]
