index-a1af6f79.js:83 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'records')

这个错误提示表明在index-a1af6f79.js文件的第83行，尝试读取一个未定义的属性'records'，导致出现了类型错误。这可能是由于在代码中没有正确初始化或赋值'records'属性所导致的。

为了解决这个问题，你可以按照以下步骤进行排查：
1. 确保在使用'records'属性之前，它已经被正确地定义和赋值。
2. 检查相关的代码逻辑，确保没有在使用'records'属性之前对其进行了意外的修改或删除操作。
3. 确保在使用'records'属性之前，它所属的对象已经被正确地创建和初始化。
4. 检查是否存在异步操作，可能是在异步操作完成之前就尝试访问'records'属性。

如果以上步骤都没有解决问题，你可以提供更多的代码细节或错误上下文，以便我能够更准确地帮助你解决这个问题。

A21: a. ostream& tab( ostream& output ) is a valid user-defined output stream manipulator header.

A22: c. 11.00 will be output by the statement.

A23: c. internal is the stream manipulator that causes an outputted number’s sign to be left justified, its magnitude to be right justified and the center space to be filled with fill characters.

A24: d. cout.fill(' ') restores the default fill character, which is a space.

A25: c. "oct" or "hex" will be displayed in the output stream when the showbase flag is set.

A26: b. 1.23450e-003 and 1.23450e-003 will be output by the statements.

A27: d. All hexadecimal numbers appearing in the form AF6 does not guarantee that the uppercase flag has been set.

A28: a. The old style of representing true/false values used -1 to indicate false and 1 to indicate true is not true. False is represented by 0 and true is represented by any non-zero value.

http://httpbin.org/get

http://httpbin.org是一个测试HTTP请求/响应服务的网站。它可以模拟各种HTTP请求和响应，例如GET，POST，PUT等，并返回有用的信息，例如请求头，ip地址等。在这个网站中，/get是一个简单的GET请求的URL，用于返回请求头和查询参数。因此，http://httpbin.org/get? 可以用于测试HTTP GET请求。

这里是一个使用Python的requests库发送HTTP GET请求的例子，该请求将返回包含请求头和查询参数的JSON响应。

import requests

response = requests.get("http://httpbin.org/get?param1=value1&param2=value2")

print(response.json())

输出:

{
  "args": {
    "param1": "value1",
    "param2": "value2"
  },
