这个ruby代码有什么问题？

Question

我收到“400 Bad Request”和“你忘了身体变量吗？” 代码：

require "rest-client"
require "json"

# This is the ID that you copied down in the last exercise
your_folder_id = "816582409"

# Add the "body" variable here
body = { "description" => "I made this on Codecademy!"
} 

response = RestClient.put(
"https://api.box.com/2.0/folders/#{816582409}",
JSON.generate(body),
:authorization => "Bearer" << "AKGEp7MoDfLAKnMyxTt3nSNtohXW3bt1"
)

JSON.parse(response.body)["description"]

Answer 1

api通话的网址不应该是https://api.box.com/2.0/folders/816582409或"https://api.box.com/2.0/folders/#{@your_folder_id}"？

Answer 2

你在Bearer和废话之间缺少一个空格。你有类似的东西：

response = RestClient.put(
"https://api.box.com/2.0/folders/#{816582409}", 
JSON.generate(body),
:authorization => "Bearer " << "AKGEp7MoDfLAKnMyxTt3nSNtohXW3bt1"
)

Answer 3

由于字符串插值，

"https://api.box.com/2.0/folders/#{816582409}"评估为"https://api.box.com/2.0/folders/"。正如ararog建议的那样，将变量本身放在：#{@your_folder_id}或普通数字中，而不是#{816582409}
