字段“id”需要一个数字,但获取的却是<Listing: Ps4 Pro>

这个问题出现的原因是在获取“id”字段时,返回的却是一个名为“Listing: Ps4 Pro”的列表,而不是一个数字。这可能是由于数据源或代码逻辑错误导致的。

为了解决这个问题,需要进行以下步骤:

  1. 检查数据源:首先,确认数据源是否正确。查看数据源是否包含名为“id”的字段,并验证该字段是否为数字类型。如果数据源不正确,需要修复数据源或更改数据源。
  2. 检查代码逻辑:检查代码中获取“id”字段的逻辑。确保代码逻辑正确,并且在获取“id”字段时应该返回一个数字。如果代码逻辑有误,需要修复代码逻辑,使其正确返回数字类型。
  3. 错误处理:在获取“id”字段时,添加适当的错误处理机制。如果返回的不是数字,可以抛出一个异常或返回一个默认值,以避免影响程序的其他部分。

  • 【Linux】《how linux work》第八章 流程和资源利用的近距离观察(第一部分)

    This chapter takes you deeper into the relationships between processes, the kernel, and system resources. There are three basic kinds of hardware resources: CPU, memory, and I/O. Processes vie for these resources, and the kernel’s job is to allocate resources fairly. The kernel itself is also a resource—a software resource that processes use to perform tasks such as creating new processes and communicating with other processes. Many of the tools that you see in this chapter are often thought of as performance-monitoring tools. They’re particularly helpful if your system is slowing to a crawl and you’re trying to figure out why. However, you shouldn’t get too distracted by performance; trying to optimize a system that’s already working correctly is often a waste of time. Instead, concentrate on understanding what the tools actually measure, and you’ll gain great insight into how the kernel works.
