http.validateHeaderName(name)

• name <string>

对提供的 name 执行低级验证，这些验证在调用 res.setHeader(name, value) 时进行。

🌐 Performs the low-level validations on the provided name that are done when res.setHeader(name, value) is called.

将非法值作为 name 传递会导致抛出 TypeError，错误代码为 code: 'ERR_INVALID_HTTP_TOKEN'。

🌐 Passing illegal value as name will result in a TypeError being thrown, identified by code: 'ERR_INVALID_HTTP_TOKEN'.

在将头信息传递给 HTTP 请求或响应之前，并不需要使用这种方法。HTTP 模块会自动验证这些头信息。示例：

🌐 It is not necessary to use this method before passing headers to an HTTP request or response. The HTTP module will automatically validate such headers. Examples:

示例：

🌐 Example:

const { validateHeaderName } = require('node:http');

try {
  validateHeaderName('');
} catch (err) {
  err instanceof TypeError; // --> true
  err.code; // --> 'ERR_INVALID_HTTP_TOKEN'
  err.message; // --> 'Header name must be a valid HTTP token [""]'
} 拷贝
