Question

我希望执行HTTP请求，不进行任何形式的缓存。我使用HttpUrlConnection，并设置每个可能的参数来禁用缓存，但每次运行后我都会在第二个请求后继续获取代码304。

我使用以下标题：

"Cache-Control: no-cache"
"Cache-Control: no-store"
"Pragma: no-cache"

并设置httpUrlConnection.setUseCaches(false)

如果我杀了app（最近列表），它会再次正常执行第一个请求，然后再回到304.

如何强制完整请求并且每次都获得200个？

初始化HttpUrlConnection的代码

HttpURLConnection httpUrlConnection = (HttpURLConnection) url.openConnection();
httpUrlConnection.setRequestMethod("GET");
httpUrlConnection.setInstanceFollowRedirects(true);
httpUrlConnection.setConnectTimeout(5000);
httpUrlConnection.setReadTimeout(20000);
httpUrlConnection.setDoOutput(false);
httpUrlConnection.setRequestProperty("Connection", "close");
httpUrlConnection.setUseCaches(false);
httpUrlConnection.addRequestProperty("Cache-Control", "no-cache");
httpUrlConnection.addRequestProperty("Cache-Control", "no-store");
httpUrlConnection.addRequestProperty("pragma", "no-cache");
httpUrlConnection.setIfModifiedSince(0);

Answer 1

connection.addRequestProperty("Cache-Control", "no-cache");应按照API，

上的文档工作

但是，您也可以通过

验证缓存的响应

connection.addRequestProperty("Cache-Control", "max-age=0");
