HTTPCli_sendRequest error

Hi Kim,


Can you please make sure server is not closing the connection.

Yes, the server is not closing.
It occur the error, every 100th.

Hi Kim,

Is it possible to share some example code with your server to reproduce this at our end.

Regards,

Aashish

Hi Aashish.

while(1) {
	osi_MsgQRead(&g_NetQueue, &RecvQue, OSI_WAIT_FOREVER);
	if(PUB_MOTOR1_STATUS == RecvQue) {
		static int count=0;
		lRetVal = HTTPPostMethod(&httpClient[HTTPCLI_SENDACT1], SENDACT1);
		if(lRetVal < 0)
		{
			UART_PRINT("HTTP Container Post failed.\n\r");
		}
		UART_PRINT("%s : count(%d)\n\r", __FUNCTION__, ++count);
	}
}

I am waiting the message "PUB_MOTOR1_STATUS".
And if I get the message, invoke the function "HTTPPostMethod".

If you need more infomation, reply please.

Hi Aashish.

I tested by other way.

I used "GET" method to restful test site "http://resttesttest.com/".

And I imported the example source "http_client_demo".

I changed some sources as follows,

#define HOST_NAME        "httpbin.org"
#define HOST_PORT           80
static int HTTPGetMethod(HTTPCli_Handle httpClient)
{

	long lRetVal = 0;
	HTTPCli_Field fields[2] = {
		{HTTPCli_FIELD_NAME_HOST, HOST_NAME},
		{NULL, NULL}
	};
	bool        moreFlags;


	/* Set request header fields to be send for HTTP request. */
	HTTPCli_setRequestFields(httpClient, fields);

	/* Send GET method request. */
	/* Here we are setting moreFlags = 0 as there are no more header fields need to send
	at later stage. Please refer HTTP Library API documentaion @ HTTPCli_sendRequest
	for more information.
	*/
	moreFlags = 0;
	lRetVal = HTTPCli_sendRequest(httpClient, HTTPCli_METHOD_GET, "/get", moreFlags);
	if(lRetVal < 0)
	{
		UART_PRINT("Failed to send HTTP GET request.\n\r");
		return lRetVal;
	}


	lRetVal = readResponse(httpClient);

	return lRetVal;
}

int main()
{
	long lRetVal = -1;
	HTTPCli_Struct httpClient;

	//
	// Board Initialization
	//
	BoardInit();

	//
	// Configure the pinmux settings for the peripherals exercised
	//
	PinMuxConfig();

	//
	// Configuring UART
	//
	InitTerm();

	//
	// Display banner
	//
	DisplayBanner(APP_NAME);

	InitializeAppVariables();

	lRetVal = ConnectToAP();
	if(lRetVal < 0)
	{
		LOOP_FOREVER();
	}

	lRetVal = ConnectToHTTPServer(&httpClient);
	if(lRetVal < 0)
	{
		LOOP_FOREVER();
	}


	while(1)
	{
		int cnt;
		static int count=0;

		cnt = 3000000;
		while(cnt)
		{
			cnt--;
		}
		UART_PRINT("\n\r");
		UART_PRINT("HTTP Get Begin:\n\r");
		lRetVal = HTTPGetMethod(&httpClient);
		if(lRetVal < 0)
		{
			UART_PRINT("HTTP Post Get failed.\n\r");
		}
		UART_PRINT("HTTP Get End [%d]:\n\r", count++);
		UART_PRINT("\n\r");
		if(count >= 100)
			count = 0;
		// Stop the CC3200 device

	LOOP_FOREVER();
}

I used SDK version "CC3200SDK_1.1.0".

This source also occur error at 100th request.

Check please.

Hi Kim,


As suspected server closing the connection after 99th request. Refer HTTP response field "connection: close" of 99th request below. For all other request server responding with keep-alive in connection header.

Hi Aashish

Thank you for your advice.

By the way, must I again connect  to a http server whenever I request a Restful method?

Gwanyoung Kim.

Hi Kim,

Yes you need to re-initiate all steps once you get "connection:close" header filed from server.
