JsonRequest

public JsonRequest(java.lang.String url,
           java.lang.String requestBody,
           Response.Listener<T> listener,
           Response.ErrorListener errorListener)

已过时。 Use #JsonRequest(int, String, String, Listener, ErrorListener).

JsonRequest

public JsonRequest(int method,
           java.lang.String url,
           java.lang.String requestBody,
           Response.Listener<T> listener,
           Response.ErrorListener errorListener)

方法详细资料

onFinish

protected void onFinish()

从类复制的说明: Request

clear listeners when finished

覆盖:

onFinish 在类中 Request<T>

deliverResponse

protected void deliverResponse(T response)

从类复制的说明: Request

Subclasses must implement this to perform delivery of the parsed response to their listeners. The given response is guaranteed to be non-null; responses that fail to parse are not delivered.

指定者:

deliverResponse 在类中 Request<T>

参数:

response - The parsed response returned by Request.parseNetworkResponse(NetworkResponse)

parseNetworkResponse

protected abstract Response<T> parseNetworkResponse(NetworkResponse response)

从类复制的说明: Request

Subclasses must implement this to parse the raw network response and return an appropriate response type. This method will be called from a worker thread. The response will not be delivered if you return null.

指定者:

parseNetworkResponse 在类中 Request<T>

参数:

response - Response from the network

返回:

The parsed response, or null in the case of an error

getPostBodyContentType

public java.lang.String getPostBodyContentType()

已过时。 Use getBodyContentType().

覆盖:

getPostBodyContentType 在类中 Request<T>

getPostBody

public byte[] getPostBody()

已过时。 Use getBody().

从类复制的说明: Request

Returns the raw POST body to be sent.

覆盖:

getPostBody 在类中 Request<T>

getBodyContentType

public java.lang.String getBodyContentType()

从类复制的说明: Request

Returns the content type of the POST or PUT body.

覆盖:

getBodyContentType 在类中 Request<T>

getBody

public byte[] getBody()

从类复制的说明: Request

Returns the raw POST or PUT body to be sent.

By default, the body consists of the request parameters in application/x-www-form-urlencoded format. When overriding this method, consider overriding Request.getBodyContentType() as well to match the new body format.

覆盖:

getBody 在类中 Request<T>
