接口 Call

所有超级接口:

Cloneable

public interface Call
extends Cloneable

A call is a request that has been prepared for execution. A call can be canceled. As this object represents a single request/response pair (stream), it cannot be executed twice.

方法详细资料

request

Request request()

Returns the original request that initiated this call.

execute

Response execute()
          throws IOException

Invokes the request immediately, and blocks until the response can be processed or is in error.

To avoid leaking resources callers should close the Response which in turn will close the underlying ResponseBody.

   // ensure the response (and underlying response body) is closed
   try (Response response = client.newCall(request).execute()) {
     ...
   }

 

The caller may read the response body with the response's Response.body method. To avoid leaking resources callers must close the response body or the Response.

Note that transport-layer success (receiving a HTTP response code, headers and body) does not necessarily indicate application-layer success: response may still indicate an unhappy HTTP response code like 404 or 500.

抛出:

IOException - if the request could not be executed due to cancellation, a connectivity problem or timeout. Because networks can fail during an exchange, it is possible that the remote server accepted the request before the failure.

IllegalStateException - when the call has already been executed.

enqueue

void enqueue(Callback responseCallback)

Schedules the request to be executed at some point in the future.

The dispatcher defines when the request will run: usually immediately unless there are several other requests currently being executed.

This client will later call back responseCallback with either an HTTP response or a failure exception.

抛出:

IllegalStateException - when the call has already been executed.

cancel

void cancel()

Cancels the request, if possible. Requests that are already complete cannot be canceled.

isExecuted

boolean isExecuted()

Returns true if this call has been either executed or enqueued. It is an error to execute a call more than once.

isCanceled

boolean isCanceled()

timeout

Timeout timeout()

Returns a timeout that spans the entire call: resolving DNS, connecting, writing the request body, server processing, and reading the response body. If the call requires redirects or retries all must complete within one timeout period.

Configure the client's default timeout with OkHttpClient.Builder.callTimeout.

clone

Call clone()

Create a new, identical call to this one which can be enqueued or executed even if this call has already been.
