IE10返回的参数看起来像是对JSON的双重转换:
=> {"{\"statementId\":"=>
{"\"b3dsecret9-bsecret741-23secreta806c\""=>
{",\"Content-Type\":"=>
{"\"application/json\""=>
{",\"content\":"=>
{"\"{\\\"context\\\":{\\\"registration\\\":\\\"27\\\",\\\"contextActivities\\\":{\\\"parent\\\":{\\\"id\\\":\\\"6LHIJumrnmV_course_id\\\"},\\\"grouping\\\":{\\\"id\\\":\\\"6LHIJumrnmV_course_id\\\"}}},\\\"actor\\\":213,\\\"verb\\\":\\\"attempted\\\",\\\"object\\\":{\\\"id\\\":\\\"6LHIJumrnmV_course_id\\\",\\\"definition\\\":{\\\"name\\\":{\\\"und\\\":\\\"\\\"},\\\"type\\\":\\\"Course\\\",\\\"description\\\":{\\\"und\\\":\\\"\\\"}}}}\""=>
{",\"registration\":"=>
{"\"27\""=>
{",\"AWSAccessKeyId\":"=>
{"\"secretIAIVsecretPHsecretQ\""=>
{",\"Signature\":"=>
{"\"PJ /OW K5secretasyXsecret5A"=>
"\"],\"Expires\":[\"1396873090\"],\"Authorization\":[\"\"]}"}}}}}}}}}}},
"method"=>"PUT",
"controller"=>"quizzes",
"action"=>"statements"}
IE Edge,Safari,Chrome和Firefox会像这样返回我的参数:
=> {"registration"=>["27"],
"Content-Type"=>["application/json"],
"Signature"=>["secretkqPJGPEsecret01ksecret"],
"AWSAccessKeyId"=>["Asecret6secretPHsecretQ"],
"statementId"=>["5919c4f4-b71c-40dd-81dc-ab63cfc824bd"],
"Expires"=>["1396873699"],
"Authorization"=>[""],
"content"=>
["{\"object\":{\"definition\":{\"type\":\"Course\",\"name\":{\"und\":\"\"},\"description\":{\"und\":\"\"}},\"id\":\"6LHIJumrnmV_course_id\"},\"verb\":\"attempted\",\"context\":{\"registration\":\"27\",\"contextActivities\":{\"parent\":{\"id\":\"6LHIJumrnmV_course_id\"},\"grouping\":{\"id\":\"6LHIJumrnmV_course_id\"}}},\"actor\":213}"],
"method"=>"PUT",
"controller"=>"quizzes",
"action"=>"statements",
"quiz"=>{}
所以我的代码可以方便地解析这个:
content = params[:content] || params['content']
response = JSON.parse(content.first)
并且presto!我有一个可行的内容。但是,首先提到的Hash,我不知道如何转换它。我是否应该考虑使用match / gsub技术来删除所有那些邪恶的正斜杠?有没有办法将其破译成看起来像我后一个哈希的东西?

从您的回答开始,我会使用escape_utils
gem解析key
:
require 'escape_utils'
def nested_hash_value(obj,key)
# nested_hash_value(params, ",\"content\":")
if obj.respond_to?(:key?) && obj.key?(key)
obj[key]
elsif obj.respond_to?(:each)
r = nil
obj.find{ |*a| r=nested_hash_value(a.last,key) }
r
end
end
extract = nested_hash_value(params, ",\"content\":")
key = extract.keys.first
response = JSON.parse EscapeUtils.unescape_javascript(key).gsub(/^"|"$/,'')
这避免了使用邪恶的eval
事物。
更一般地说,我认为你应该以这种方式建立你的处理:
def smell_of_ie_weirdness?
# Detects whether the request seems like the one sent by IE 10,
# something like params keys formatting checking etc.
end
def extracted_response
if smell_of_ie_weirdness?
# Do weird stuff
extract_response_for_weird_ie
else
# Be clean and polite
extract_response
end
end

这给了我一个答案..它不是最好的。这肯定是一个黑客。但我觉得这是我唯一得到的东西。
def nested_hash_value(obj,key)
# nested_hash_value(params, ",\"content\":")
if obj.respond_to?(:key?) && obj.key?(key)
obj[key]
elsif obj.respond_to?(:each)
r = nil
obj.find{ |*a| r=nested_hash_value(a.last,key) }
r
end
end
extract = nested_hash_value(params, ",\"content\":")
key = extract.keys.first
decoded_hash = key.to_s.gsub(/\\/,'').gsub(/\"/,"'").gsub(/'$|^'/,'').gsub(':','=>')
response = eval decoded_hash
如果我在两个输出之间进行比较==
,则返回true
。
然后我把它全部放在救援区......
begin
content = params[:content] || params['content']
response = JSON.parse(content.first)
rescue
perform_fd_up_IE_fixer # :)
end
