open fun isOneShot(): Boolean
Returns true if this body expects at most one call to writeTo and can be transmitted at most once. This is typically used when writing the request body is destructive and it is not possible to recreate the request body after it has been sent.
This method returns false unless it is overridden by a subclass.
By default OkHttp will attempt to retransmit request bodies when the original request fails
due to a stale connection, a client timeout (HTTP 408), a satisfied authorization challenge
(HTTP 401 and 407), or a retryable server failure (HTTP 503 with a Retry-After: 0
header).
