我正在获取上述外部URL的XML验证。但是如果我在URL中使用一个查询参数，它就可以正常工作。

Answer 1

这是因为你需要逃避＆amp;参数（例如，＆amp;）使其成为有效的XML。这是一个完整的Ruby代码示例，可以运行并演示：

require 'aws-sdk'

aws_access_key_id = 'YOUR_ACCESS_ID'
aws_secret_access_key = 'YOUR_SECRET_KEY'
endpoint = 'https://mturk-requester-sandbox.us-east-1.amazonaws.com'
region = 'us-east-1'

# Uncomment this line to use in production
# endpoint = 'https://mturk-requester.us-east-1.amazonaws.com'

#credentials = Aws::Credentials.new(aws_access_key_id, aws_secret_access_key)
mturk = Aws::MTurk::Client.new(endpoint: endpoint) #, credentials: credentials, region: region)

response = mturk.create_hit(title: "Example HIT", 
                            description: "Example HIT", 
                            lifetime_in_seconds: 60 * 60, 
                            assignment_duration_in_seconds: 60 * 5,
                            max_assignments: 1, 
                            reward: "0.25", 
                            question: QUESTION)

p "Your HIT is created. The HIT ID is #{response.hit.hit_id}"
