Class StandardHttpRequestor

java.lang.Object

com.dropbox.core.http.HttpRequestor

com.dropbox.core.http.StandardHttpRequestor

public class StandardHttpRequestor
extends HttpRequestor

HttpRequestor implementation that uses Java's standard library HttpsURLConnection. If you just want a connection with the default settings, use the predefined INSTANCE.

If you want to customize the way the connection is configured, create a subclass that overrides configureConnection(javax.net.ssl.HttpsURLConnection).

startPost

public com.dropbox.core.http.StandardHttpRequestor.Uploader startPost(java.lang.String url,
                                                                      java.lang.Iterable<HttpRequestor.Header> headers)
                                                               throws java.io.IOException

Specified by:

startPostInStreamingMode

public com.dropbox.core.http.StandardHttpRequestor.Uploader startPostInStreamingMode(java.lang.String url,
                                                                                     java.lang.Iterable<HttpRequestor.Header> headers)

Overrides:

startPostInStreamingMode in class HttpRequestor

Throws:

java.io.IOException

startPut

public com.dropbox.core.http.StandardHttpRequestor.Uploader startPut(java.lang.String url,
                                                                     java.lang.Iterable<HttpRequestor.Header> headers)

Specified by:

startPut in class HttpRequestor

Throws:

java.io.IOException

configureConnection

@Deprecated
protected void configureConnection(javax.net.ssl.HttpsURLConnection conn)
                                        throws java.io.IOException

Deprecated. use configure(java.net.HttpURLConnection) instead.

Can be overridden to configure the underlying HttpsURLConnection used to make network requests. If you override this method, you should probably call super.configureConnection(conn) in your overridden method.

Throws:

java.io.IOException

configure

protected void configure(java.net.HttpURLConnection conn)
                  throws java.io.IOException

Can be overriden to configure the underlying HttpURLConnection used to make network requests using https. Typically the connection will be a HttpsURLConnection, but that is dependent on the Java runtime. Care should be taken when casting the connection (check your JRE).

If you are using Google App Engine, configure your DbxRequestConfig to use GoogleAppEngineRequestor as its default HttpRequestor. If you use StandardHttpRequestor in Google App Engine, SSL certificates may not be validated and your app will susceptible to Man-in-the-Middle attacks.

Parameters:

conn - URL connection object returned after creating an https network request.

Throws:

java.io.IOException

interceptResponse

protected void interceptResponse(java.net.HttpURLConnection conn)
                          throws java.io.IOException

Called before returning Response from a request.

This method should be used by subclasses to add any logging, analytics, or cleanup necessary. Note that the connection response code and response streams will already be fetched before calling this method. This means any IOException from reading the response should already have occurred before this method is called.

Do not consume the response or error streams in this method.

Parameters:

conn - HTTP URL connection

Throws:

java.io.IOException
