Example 66 with SessionInputBuffer

use of org.apache.hc.core5.http.io.SessionInputBuffer in project httpcomponents-core by apache.

the class TestChunkCoding method testCorruptChunkedInputStreamTruncatedCRLF.

// Truncated stream (missing closing CRLF)
@Test
public void testCorruptChunkedInputStreamTruncatedCRLF() throws IOException {
    final String s = "5\r\n01234";
    final SessionInputBuffer inBuffer = new SessionInputBufferImpl(16);

    Assertions.assertEquals(5, in.read(tmp));
    Assertions.assertThrows(MalformedChunkCodingException.class, () -> in.read());
    in.close();
}

Example 67 with SessionInputBuffer

use of org.apache.hc.core5.http.io.SessionInputBuffer in project httpcomponents-core by apache.

the class AbstractMessageParser method parseHeaders.

/**
 * Parses HTTP headers from the data receiver stream according to the generic
 * format as specified by the HTTP/1.1 protocol specification.
 *
 * @param inBuffer Session input buffer
 * @param inputStream Input stream
 * @param maxHeaderCount maximum number of headers allowed. If the number
 *  of headers received from the data stream exceeds maxCount value, an
 *  IOException will be thrown. Setting this parameter to a negative value
 *  or zero will disable the check.
 * @param maxLineLen maximum number of characters for a header line,
 *  including the continuation lines. Setting this parameter to a negative
 *  value or zero will disable the check.
 * @param parser line parser to use.
 * @param headerLines List of header lines. This list will be used to store
 *   intermediate results. This makes it possible to resume parsing of
 *   headers in case of a {@link java.io.InterruptedIOException}.
 *
 * @return array of HTTP headers
 *
 * @throws IOException in case of an I/O error
 * @throws HttpException in case of HTTP protocol violation
 *
 * @since 4.1
