为什么Spotify响应不允许我在收到错误时过去？

Question

我只是试图寻找一个用户时，如果用户存在，甜的，如果没有，我想声明所以...

# Install if you haven't already 
require 'twilio-ruby' 
require 'rspotify' 

# Twilio Security Access 
account_sid = 'enter_your_sid' 
auth_token = 'enter_your_auth_token' 

# Spotify User Lookup 
def user_lookup(user_search) 
    spotify_user = RSpotify::User.find(user_search) 
end 

# Crafted text message using Twilio 
def text(account_sid, auth_token, message) 
    client = Twilio::REST::Client.new account_sid, auth_token 

    client.messages.create(
     from: '+twilio_number', # I guess you can use my number for testing 
     to: '+personal_number', # Feel free to enter your number to get the messages 
     body: message 
    ) 
end 

# Ask who you should lookup on Spotify 
puts "Who would you like to look up? " 
user_input_1 = gets.chomp 

# Make sure the user exists 
if user_lookup(user_input_1).id != user_input_1 # Test with "zxz122" 
    msg = "Could not find that Spotify user!" 
    text(account_sid, auth_token, msg) 
    puts "Spotify user details send failure!" 
else 
    user_exist = user_lookup(user_input_1) 
    user_profile_url = "https://open.spotify.com/user/#{user_input_1}" 
    msg = "Check out #{user_input_1} on Spotify: #{user_profile_url}" 
    text(account_sid, auth_token, msg) 
    puts "Spotify user details have been sent!" 
end 

我不断收到的响应...

`return!': 404 Resource Not Found (RestClient::ResourceNotFound) 

那么为什么它没有击中我的if语句并触发“找不到Spotify用户！”？

Answer 1

为什么？ RestClient的创建者设计了gem在资源不存在的情况下引发异常（aka返回404 not found）。

要解决此问题只是改变方法：

def user_lookup(user_search) 
    RSpotify::User.find(user_search) rescue false 
end 

，改变你的if ... else块：

if user_lookup(user_input_1) 
    user_profile_url = "https://open.spotify.com/user/#{user_input_1}" 
    msg = "Check out #{user_input_1} on Spotify: #{user_profile_url}" 
    text(account_sid, auth_token, msg) 
    puts "Spotify user details have been sent!" 
else 
    msg = "Could not find that Spotify user!" 
    text(account_sid, auth_token, msg) 
    puts "Spotify user details send failure!" 
end
