6.测试

http://localhost:8082/Spark/chat

{
    "content":"帮我写一份本地js模糊查询"
}


{
	"code": 200,
	"msg": "天梦星",
	"data": "以下是一个简单的本地 JavaScript 模糊查询的示例代码：\n\n```javascript\n// 假设有一个数据列表，包含商品的名称和价格\nconst products = [\n  { name: \"苹果\", price: 1.99 },\n  { name: \"香蕉\", price: 0.99 },\n  { name: \"橙子\", price: 2.49 },\n  { name: \"草莓\", price: 3.99 },\n];\n\n// 实现模糊查询函数\nfunction searchProducts(keyword) {\n  // 将关键字转换为小写，以忽略大小写的差异\n  const lowerCaseKeyword = keyword.toLowerCase();\n\n  // 使用数组的 filter 方法进行模糊查询\n  const results = products.filter((product) => {\n    // 将商品名称转换为小写，并使用 includes 方法检查是否包含关键字\n    return product.name.toLowerCase().includes(lowerCaseKeyword);\n  });\n\n  return results;\n}\n\n// 测试模糊查询函数\nconst keyword = \"果\"; // 输入要查询的关键字\nconst searchResults = searchProducts(keyword);\nconsole.log(searchResults);\n```\n\n上述代码中，我们首先定义了一个包含商品名称和价格的数据列表 `products`。然后实现了一个 `searchProducts` 函数，该函数接受一个关键字作为参数，并返回包含该关键字的商品列表。在函数内部，我们将关键字转换为小写，并使用数组的 `filter` 方法对商品列表进行模糊查询。最后，我们通过调用 `searchProducts` 函数并打印结果来进行测试。"
}

备注：这步骤是我的业务流程，你可以省略不写

JwtInfo jwtInfo = jwtRedistService.getUserInfo(token);

返回数据格式，已有忽略

@Data
public class Result {
    private Integer code;//状态码
    private Object msg;//状态信息或者报错信息
    private Object data;//返回数据
    private Integer count;//总条数
}
