HI , I am a starter with http2. Now I want to make a http2 get request with MFI SDK4.0.1 .The request is like this:

:method = GET

:scheme = https

:path = /{{API version}}/directives

authorization = Bearer {{YOUR_ACCESS_TOKEN}}

the wirte header and write request is right ,but the http client will disconnect immediately after http request flush.It is normal?

Below is how I creat a get request:

static const char* request_uris[] =

{

  [0] = "/get"

};

    WPRINT_APP_INFO( ( "Resolving IP address of HTTPS server\n" ) );
    wiced_hostname_lookup(CONNECTION_SERVER_HOST, &ip_address, DNS_TIMEOUT_MS);
    WPRINT_APP_INFO( ( "%s is at %u.%u.%u.%u\n", CONNECTION_SERVER_HOST,
                                                 (uint8_t)(GET_IPV4_ADDRESS(ip_address) >> 24),
                                                 (uint8_t)(GET_IPV4_ADDRESS(ip_address) >> 16),
                                                 (uint8_t)(GET_IPV4_ADDRESS(ip_address) >> 8),
                                                 (uint8_t)(GET_IPV4_ADDRESS(ip_address) >> 0) ) );

    /* Initialize the root CA certificate */
    result = wiced_tls_init_root_ca_certificates( amazon_root_ca_certificate, strlen( amazon_root_ca_certificate ) );
    if ( result != WICED_SUCCESS )
    {
        WPRINT_APP_INFO( ( "Error: Root CA certificate failed to initialize: %u\n", result) );
    }
    WPRINT_APP_INFO(("Root CA certificate successed to initialize!\n"));

    sprintf(https_header,":method = GET\r\n:scheme = https\r\n:path = /v20160207/directives\r\nauthorization = Bearer %s\r\n",access_token);
    WPRINT_APP_INFO(("\n%s\n\n", https_header));

    result = http_client_init( &client, WICED_STA_INTERFACE, event_handler, NULL );

    if (result == WICED_SUCCESS)
{
    WPRINT_APP_INFO( ( "http inited success  %d\n", result ) );
}
else WPRINT_APP_INFO( ( "http failed to init %d\n", result ) );
    /* configure HTTP client parameters */
    client_configuration.flag = HTTP_CLIENT_CONFIG_FLAG_SERVER_NAME | HTTP_CLIENT_CONFIG_FLAG_MAX_FRAGMENT_LEN;
    client_configuration.server_name = (uint8_t*)CONNECTION_SERVER_HOST;
    client_configuration.max_fragment_length = TLS_FRAGMENT_LENGTH_4096;
    http_client_configure(&client, &client_configuration);

    result = http_client_connect( &client, (const wiced_ip_address_t*)&ip_address, SERVER_PORT, HTTP_USE_TLS, CONNECT_TIMEOUT_MS );
    if (result == WICED_SUCCESS)
    {
    WPRINT_APP_INFO( ( "http connected %d\n", result ) );

        header[0].field        = HTTP_HEADER_HOST;
        header[0].field_length = sizeof( HTTP_HEADER_HOST) - 1;
        header[0].value        = CONNECTION_SERVER_HOST;
        header[0].value_length = sizeof( CONNECTION_SERVER_HOST ) - 1;

char *http_get_length_string = malloc(10);

     itoa(strlen(https_header),http_get_length_string,10);


header[2].field        = HTTP_HEADER_CONTENT_TYPE;
header[2].field_length = sizeof( HTTP_HEADER_CONTENT_TYPE ) - 1;
header[2].value        = "application/x-www-form-urlencoded";
    header[2].value_length = sizeof( "application/x-www-form-urlencoded" ) - 1;
        header[1].field        = HTTP_HEADER_CONTENT_LENGTH;
header[1].field_length = sizeof( HTTP_HEADER_CONTENT_LENGTH ) - 1;
header[1].value        = http_get_length_string;
header[1].value_length = strlen( http_get_length_string );

    header[3].field        = "Connection: ";
    header[3].field_length = sizeof("Connection: ") - 1;
    header[3].value        = "Keep-Alive";
    header[3].value_length = sizeof( "Keep-Alive" ) - 1;
http_request_init( &requests[0], &client, HTTP_GET, request_uris[0], HTTP_2 );
for(uint8_t i=0;i<4;i++)
{
http_request_write_header( &requests[0], &header, 1 );
WPRINT_APP_INFO( ( "http_request_write_header %d result : %d \n" ,i,result) );
}
http_request_write_end_header( &requests[0] );
http_request_write(&requests[0],(uint8_t *)https_header,sizeof(https_header)-1);//write body
WPRINT_APP_INFO( ( "http_request_write result : %d \n" ,result) );
http_request_write_end_header( &requests[0] );
http_request_flush( &requests[0] );
    }
    else WPRINT_APP_INFO( ( "http failed to connect %d\n", result ) );

You can refer to test.http2 example in WICED SDK 6.1 for the same.
