public static HttpResponse createResponse(Request<?> request,
                                          org.apache.http.client.methods.HttpRequestBase method,
                                          org.apache.http.HttpResponse apacheHttpResponse,
                                          org.apache.http.protocol.HttpContext context)
                                   throws IOException

Creates and initializes an HttpResponse object suitable to be passed to an HTTP response handler object.

Parameters:

request - Marshalled request object.

method - The HTTP method that was invoked to get the response.

context - The HTTP context associated with the request and response.

Returns:

The new, initialized HttpResponse object ready to be passed to an HTTP response handler object.

Throws:

IOException - If there were any problems getting any response information from the HttpClient method object.

newStringEntity

public static org.apache.http.HttpEntity newStringEntity(String s)

Utility function for creating a new StringEntity and wrapping any errors as a SdkClientException.

Parameters:

s - The string contents of the returned HTTP entity.

Returns:

A new StringEntity with the specified contents.

newBufferedHttpEntity

public static org.apache.http.HttpEntity newBufferedHttpEntity(org.apache.http.HttpEntity entity)
                                                        throws FakeIOException

Utility function for creating a new BufferedEntity and wrapping any errors as a SdkClientException.

Parameters:

entity - The HTTP entity to wrap with a buffered HTTP entity.

Returns:

A new BufferedHttpEntity wrapping the specified entity.

Throws:

FakeIOException - only for test simulation

newClientContext

public static org.apache.http.client.protocol.HttpClientContext newClientContext(HttpClientSettings settings,
                                                                                 Map<String,? extends Object> attributes)

Returns a new HttpClientContext used for request execution.

disableNormalizeUri

public static void disableNormalizeUri(org.apache.http.client.config.RequestConfig.Builder requestConfigBuilder)

From Apache v4.5.8, normalization should be disabled or AWS requests with special characters in URI path will fail with Signature Errors.

setNormalizeUri is added only in 4.5.8, so customers using the latest version of SDK with old versions (4.5.6 or less) of Apache httpclient will see NoSuchMethodError. Hence this method will suppress the error. Do not use Apache version 4.5.7 as it breaks URI paths with special characters and there is no option to disable normalization.

newProxyCredentialsProvider

public static org.apache.http.client.CredentialsProvider newProxyCredentialsProvider(HttpClientSettings settings)

Returns a new Credentials Provider for use with proxy authentication.
