Question

java怎么主动发送http请求

Answer 1

实现思路就是先定义请求头内容，之后进行请求头设置。

• 定义请求头

LinkedHashMap<String,String> headers = new LinkedHashMap<String,String>();

headers.put("Content-type","text/xml");

headers.put("Cache-Control", "no-cache");

headers.put("Connection", "close");

• 给HttpPost 设置请求头

HttpPost httpPost = new HttpPost("地址");

if (headers != null) {

for (String key : headers.keySet()) {

httpPost.setHeader(key, headers.get(key));

}

}

备注：只需要在map中设置相应的请求头内容即可。根据实际需要修改即可
