response.appendHeader(name, value)

• name <string>
• value 字符串|字符串数组

将单个标头值附加到标头对象。

🌐 Append a single header value to the header object.

如果值是数组，这相当于多次调用此方法。

🌐 If the value is an array, this is equivalent to calling this method multiple times.

如果该头部没有以前的值，这等同于调用 response.setHeader()。

🌐 If there were no previous values for the header, this is equivalent to calling response.setHeader().

尝试设置包含无效字符的头字段名称或值将导致抛出 TypeError。

🌐 Attempting to set a header field name or value that contains invalid characters will result in a TypeError being thrown.

// Returns headers including "set-cookie: a" and "set-cookie: b"
const server = http2.createServer((req, res) => {
  res.setHeader('set-cookie', 'a');
  res.appendHeader('set-cookie', 'b');
  res.writeHead(200);
  res.end('ok');
}); 拷贝
