READ_RAW Procedure

This procedure reads the HTTP response body in binary form and returns the output in the caller-supplied buffer. The end_of_body exception will be raised if the end of the HTTP response body is reached.

Syntax

UTL_HTTP.read_raw(

r  IN OUT NOCOPY resp,
data  OUT NOCOPY RAW,
len  IN PLS_INTEGER DEFAULT NULL);

Parameters

Table 78-45 shows the parameters for the READ_RAW procedure.

Table 78-45 READ_RAW Procedure Parameters

Parameter	Description
r (IN/OUT)	The HTTP response.
data (OUT)	The HTTP response body in binary form
len (IN)	The number of bytes of data to read. If len is NULL, this procedure will read as much input as possible to fill the buffer allocated in data. The actual amount of data returned may be less than that specified if not much data is available before the end of the HTTP response body is reached or the transfer_timeout amount of time has elapsed. The default is NULL

Usage Notes

The UTL_HTTP package supports HTTP 1.1 chunked transfer-encoding. When the response body is returned in chunked transfer-encoding format as indicated in the response header, the package automatically decodes the chunks and returns the response body in de-chunked format.

If transfer timeout is set in the request of this response, read_raw waits for each data packet to be ready to read until timeout occurs. If it occurs, read_raw stops reading and returns all the data read successfully. If no data is read successfully, the transfer_timeout exception is raised. The exception can be handled and the read operation can be retried later.
