本文整理了Java中java.net.URLConnection.setRequestProperty()方法的一些代码示例，展示了URLConnection.setRequestProperty()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。URLConnection.setRequestProperty()方法的具体详情如下：
包路径：java.net.URLConnection
类名称：URLConnection
方法名：setRequestProperty

URLConnection.setRequestProperty介绍

[英]Sets the value of the specified request header field. The value will only be used by the current URLConnection instance. This method can only be called before the connection is established.
[中]设置指定请求标头字段的值。该值将仅由当前URLConnection实例使用。只能在建立连接之前调用此方法。

代码示例

URLConnection connection = new URL(url).openConnection();
connection.setDoOutput(true); // Triggers POST.
connection.setRequestProperty("Accept-Charset", charset);
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=" + charset);

try (OutputStream output = connection.getOutputStream()) {
  output.write(query.getBytes(charset));
}

InputStream response = connection.getInputStream();
// ...
