response.appendHeader(name, value)

• name <string>

• value <string> | <string[]>

将单个标头值附加到标头对象。

¥Append a single header value to the header object.

如果该值为数组，则相当于多次调用该方法。

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

如果标头没有先前的值，则相当于调用 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标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');
