类 BinaryHttpResponseHandler

java.lang.Object

com.loopj.android.http.AsyncHttpResponseHandler

com.loopj.android.http.BinaryHttpResponseHandler

所有已实现的接口:

ResponseHandlerInterface

public abstract class BinaryHttpResponseHandler
extends AsyncHttpResponseHandler

Used to intercept and handle the responses from requests made using AsyncHttpClient. Receives response body as byte array with a content-type whitelist. (e.g. checks Content-Type against allowed list, Content-length).

For example:

 AsyncHttpClient client = new AsyncHttpClient();
 String[] allowedTypes = new String[] { "image/png" };
 client.get("http://www.example.com/image.png", new BinaryHttpResponseHandler(allowedTypes) {
     @Override
     public void onSuccess(byte[] imageData) {
         // Successfully got a response
     }

     @Override
     public void onFailure(Throwable e, byte[] imageData) {
         // Response failed :(
     }
 });

BinaryHttpResponseHandler() Creates a new BinaryHttpResponseHandler
BinaryHttpResponseHandler(java.lang.String[] allowedContentTypes) Creates a new BinaryHttpResponseHandler, and overrides the default allowed content types with passed String array (hopefully) of content types.

限定符和类型	方法和说明
java.lang.String[]	getAllowedContentTypes() Method can be overriden to return allowed content types, can be sometimes better than passing data in constructor

构造器详细资料

BinaryHttpResponseHandler

public BinaryHttpResponseHandler()

Creates a new BinaryHttpResponseHandler

BinaryHttpResponseHandler

public BinaryHttpResponseHandler(java.lang.String[] allowedContentTypes)

Creates a new BinaryHttpResponseHandler, and overrides the default allowed content types with passed String array (hopefully) of content types.

参数:

allowedContentTypes - content types array, eg. 'image/jpeg' or pattern '.*'

方法详细资料

getAllowedContentTypes

public java.lang.String[] getAllowedContentTypes()

Method can be overriden to return allowed content types, can be sometimes better than passing data in constructor

返回:

array of content-types or Pattern string templates (eg. '.*' to match every response)

onSuccess

public abstract void onSuccess(int statusCode,
                               Header[] headers,
                               byte[] binaryData)

从类复制的说明: AsyncHttpResponseHandler

Fired when a request returns successfully, override to handle in your own code

指定者:

onSuccess 在类中 AsyncHttpResponseHandler

参数:

statusCode - the status code of the response

headers - return headers, if any

binaryData - the body of the HTTP response from the server

onFailure

public abstract void onFailure(int statusCode,
                               Header[] headers,
                               byte[] binaryData,
                               java.lang.Throwable error)

从类复制的说明: AsyncHttpResponseHandler

Fired when a request fails to complete, override to handle in your own code

指定者:

onFailure 在类中 AsyncHttpResponseHandler

参数:

statusCode - return HTTP status code

headers - return headers, if any

binaryData - the response body, if any

error - the underlying cause of the failure

sendResponseMessage

public final void sendResponseMessage(HttpResponse response)
                               throws java.io.IOException

从接口复制的说明: ResponseHandlerInterface

Returns data whether request completed successfully

指定者:

sendResponseMessage 在接口中 ResponseHandlerInterface

覆盖:

sendResponseMessage 在类中 AsyncHttpResponseHandler

参数:

response - HttpResponse object with data

抛出:

java.io.IOException - if retrieving data from response fails
