android - 即使连接超时和读取超时设置为默认值(无限)，接收请求超时？

Question

我正在连接到 Web 服务，但没有在 HttpURLConnection 上设置任何连接超时和读取超时。默认的连接超时和读取超时是多少？它依赖于Android手机吗？或者 Android/Java 是否有自己的超时默认值？

当我尝试获取连接超时值 (getConnectTimeout()) 和读取超时值 (getReadTimeout()) 时，它返回值 0，我assume 相当于无穷大。但是，即使它们的值为 0，有时我仍会收到请求超时错误。所以它们的值不可能等于无穷大。有人可以启发我吗？

你做过研究吗？ documentation 中详细说明了默认值.以下是相关部分:

public void setConnectTimeout (int timeout) Since: API Level 1

Sets the timeout value in milliseconds for establishing the connection to the resource pointed by this URLConnection instance. A SocketTimeoutException is thrown if the connection could not be established in this time. Default is 0 which stands for an infinite timeout.

public void setReadTimeout (int timeout) Since: API Level 1

Sets the timeout value in milliseconds for reading from the input stream of an established connection to the resource. A SocketTimeoutException is thrown if the connection could not be established in this time. Default is 0 which stands for an infinite timeout.

还有关于超时的注释:

URLConnection supports two timeouts: a connect timeout and a read timeout. By default, operations never time out.

您连接的服务器可能会使您的客户端超时。
