URLConnection.addRequestProperty介绍

[英]Adds the given property to the request header. Existing properties with the same name will not be overwritten by this method.
[中]将给定属性添加到请求标头。此方法不会覆盖同名的现有属性。

代码示例

// Gather all cookies on the first request.
URLConnection connection = new URL(url).openConnection();
List<String> cookies = connection.getHeaderFields().get("Set-Cookie");
// ...

// Then use the same cookies on all subsequent requests.
connection = new URL(url).openConnection();
for (String cookie : cookies) {
  connection.addRequestProperty("Cookie", cookie.split(";", 2)[0]);
}
// ...

  return connection.getInputStream();
 } else {
  log.warn(
    "Since the input source doesn't support range requests, the object input stream is opened from the start and "
    + "then skipped. This may make the ingestion speed slower. Consider enabling prefetch if you see this message"
    + " a lot."
