How to send http get request?

[abbateur]

Ok, I have pspsdk, I looked at examples (at least default htmlviewer example), and I didn't quite understand the code .
Is there any well commented example of sending http get request?
Or any library that allows you to skip this low level initialization routine (which I can't understand) and is also well documented?
Btw,sorry for mah engrish

I'm not sure if this is what you mean, but OSlib had a function to get a file from HTTP:

Code: Select all

int oslNetGetFile(const char *url, const char *filepath)
{
	int template, connection, request, ret, status, dataend, fd, byteswritten;
	//SceULong64 contentsize;
	unsigned char readbuffer[8192];
/*										//<-- STAS: HTTP library was already initialized (see oslNetInit()) !
	ret = sceHttpInit(20000);
	if(ret < 0)
		return OSL_ERR_HTTP_INIT;
*/										//<-- STAS END -->
	template = sceHttpCreateTemplate("OSL-agent/0.0.1 libhttp/1.0.0", 1, 1);
	if(template < 0)
		return OSL_ERR_HTTP_TEMPLATE;

	ret = sceHttpSetResolveTimeOut(template, 3000000);
	if(ret < 0)
		return OSL_ERR_HTTP_TIMEOUT;

	ret = sceHttpSetRecvTimeOut(template, 60000000);
	if(ret < 0)
		return OSL_ERR_HTTP_TIMEOUT;

	ret = sceHttpSetSendTimeOut(template, 60000000);
	if(ret < 0)
		return OSL_ERR_HTTP_TIMEOUT;

	connection = sceHttpCreateConnectionWithURL(template, url, 0);
	if(connection < 0)
		return OSL_ERR_HTTP_CONNECT;

	request = sceHttpCreateRequestWithURL(connection, PSP_HTTP_METHOD_GET, (char*)url, 0);
	if(request < 0)
		return OSL_ERR_HTTP_REQUEST;

	ret = sceHttpSendRequest(request, 0, 0);
	if(ret < 0)
		return OSL_ERR_HTTP_REQUEST;

	ret = sceHttpGetStatusCode(request, &status);
	if(ret < 0)
		return OSL_ERR_HTTP_GENERIC;

	if(status != 200)
		return 0;
	
	/* Strangelove fix
	ret = sceHttpGetContentLength(request, &contentsize);
	if(ret < 0)
		return OSL_ERR_HTTP_GENERIC;
	*/

	dataend = 0;
	byteswritten = 0;

	// Strangelove fix - Added PSP_O_TRUNC
	fd = sceIoOpen(filepath, PSP_O_WRONLY | PSP_O_TRUNC | PSP_O_CREAT, 0777);

	while(dataend == 0)
	{
		ret = sceHttpReadData(request, readbuffer, 8192);
		if(ret < 0)
		{
			sceIoWrite(fd, filepath, 4);
			sceIoClose(fd);
			return OSL_ERR_HTTP_GENERIC;
		}

		if(ret == 0)
			dataend = 1;

		if(ret > 0)
		{
			byteswritten += ret;
			sceIoWrite(fd, readbuffer, ret);
		}
	}

	sceIoClose(fd);
	sceHttpDeleteRequest(request);
	sceHttpDeleteConnection(connection);
	sceHttpDeleteTemplate(template);
//	sceHttpEnd();						//<-- STAS: This should be done in oslNetTerm() only !

	return 0;
}

If I recall correctly, I tried this ages ago and it never worked. Honestly that's as easy as it gets, I don't think you can make it any simpler to be honest. Maybe some more detailed comments would help. If you had a strong knowledge in C/C++ , it shouldn't be much of a problem though.
