Google书籍API和API密钥的重要性 [英] Google books API and the neccesity of an API key

问题描述

因此，Google声称为了使用他们的Google Books Api，您必须注册并获取API密钥。但是你可以在没有API密钥的情况下提出请求。

例如：

https://www.googleapis.com/books/v1/volumes?q=isbn:9780553819229

如果我可以在没有密钥的情况下发出请求，我为什么要注册？我不明白。

一个API密钥，API请求不会被扼杀。

不使用API​​密钥，您将更快地得到以下错误：

  {
error：{
errors：[
 {
domain： usageLimits，
reason：userRateLimitExceededUnreg，
message：用户速率超出限制，请注册，
extendedHelp：https：// code。 google.com/apis/console
} 
]，
code：403，
message：用户比率超出限制，请注册
} 
} 
  

So Google claims that in order to use their Google Books Api, you have to register and get an API key. But you can make a request without an api key.

e.g.:

https://www.googleapis.com/books/v1/volumes?q=isbn:9780553819229

Why would I register if I can make requests without a key? I don't get it.

解决方案

Along with the Terms of Use mentioned by Will, the biggest reason is that when you use an API key, the API request isn't throttled as much.

You'll get the following error much quicker without using the API key:

{
 "error": {
  "errors": [
   {
    "domain": "usageLimits",
    "reason": "userRateLimitExceededUnreg",
    "message": "User Rate Limit Exceeded. Please sign up",
    "extendedHelp": "https://code.google.com/apis/console"
   }
  ],
  "code": 403,
  "message": "User Rate Limit Exceeded. Please sign up"
 }
}
