我有一个自定义的 http 客户端,它有一个默认的超时值。代码是这样的:
type Client struct {
*http.Client
timeout time.Duration
}
func (c *Client) Send(ctx context.Context, r *http.Request) (int, []byte, error) {
// If ctx has timeout set, then don't change it.
// Otherwise, create new context with ctx.WithTimeout(c.timeout)
}
如何检查 ctx
是否设置了超时?
最佳答案
检查 context.Deadline
的 bool 返回值:
Deadline returns the time when work done on behalf of this context should be canceled. Deadline returns ok==false when no deadline is set. Successive calls to Deadline return the same results.
Deadline() (deadline time.Time, ok bool)
func (c *Client) Send(ctx context.Context, r *http.Request) (int, []byte, error) {
if _, deadlineSet := ctx.Deadline(); !deadlineSet {
ctx, _ = context.WithTimeout(ctx, c.timeout)
}
}
关于go - 我可以检查上下文是否已经设置了超时吗?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/44822381/
