 Posted: Sat Mar 01, 2008 12:45 pm Post subject: downloading files?? from internet.....How? |
 |
|
Hey all im new here, lol
SO i have a homebrew which accesses the internet,.....How do you download a file do you use?
| Code: | | copy_file("http://website.com/file.extension, "ms0:/file.extension"); |
I've tried that & it currently doesn't work?? & im connected to the internet.
im fairly sure its not going to work, but i could be wrong.
i know Dark_AleX /moonlight does it in the 3.90 M33 Unpacker/Downloader thingy
If someone knows what it is please let me know, or if there's a place that shows it already can you point me in that direction please,
Thanks all,
FaderX
p.s. I've checked usin the search option as usual in forums, & Google, and I've ended up with no results in what I'm looking for. |

| except access point connection and adress resolving which is available from samples in the sdk everything else it's the same as with the pc, so search for a good network connection in c/c++ tutorial with google |

As welltall said, you could use whatever network code and create a very basic http client, as for downloading a file you don't need much complicated things.
Anyways, the M33 updater uses the firmware libhttp which has not been added yet to the sdk, and uses it like it has been seen in the sony xmb network update.
Basically, after loading the other network modules, load http ones:
| Code: |
if (sceUtilityLoadNetModule(PSP_NET_MODULE_PARSEURI) < 0)
// error here
if (sceUtilityLoadNetModule(PSP_NET_MODULE_PARSEHTTP) < 0)
// error here
if (sceUtilityLoadNetModule(PSP_NET_MODULE_HTTP) < 0)
// error here
|
(for unload, unload them in reverse order).
And usage of library:
| Code: |
char *the_url = "http://www.someweb.com/file.bin";
u8 buf[100*1024] __attribute__((aligned(64))); // this should go as global var
u32 filesize;
int nbytes;
if (sceHttpInit(20000) < 0)
// error here
int template = sceHttpCreateTemplate("MyUserAgent/0.0.1 libhttp/1.0.0", 1, 1);
if (template < 0)
// error here
if (sceHttpSetResolveTimeOut(template, 3000000) < 0)
// error here
if (sceHttpSetRecvTimeOut(template, 60000000) < 0)
// error here
if (sceHttpSetSendTimeOut(template, 60000000) < 0)
// error here
int connection = sceHttpCreateConnectionWithURL(template, the_url, 0);
if (connection < 0)
// error here
int request = sceHttpCreateRequestWithURL(connection, 0, the_url, 0);
if (request < 0)
// error here
if (sceHttpSendRequest(request, 0, 0) < 0)
// error here
int status = sceHttpGetStatusCode(request, &status);
if (status != 200)
// error here
if (sceHttpGetContentLength(request, &filesize) < 0)
// error here
printf("File size = %d\n" filesize);
while ((nbytes = sceHttpReadData(request, buf, sizeof(buf))) != 0)
{
if (nbytes < 0)
// error here, abort loop
// Write nbytes to a file or whatever
}
|
Of course, you have to create the stub or the library for libhttp
sceHttp.S:
| Code: |
.set noreorder
#include "pspstub.s"
STUB_START "sceHttp",0x00090011,0x00530005
STUB_FUNC 0x0282A3BD,sceHttpGetContentLength
STUB_FUNC 0x1F0FC3E3,sceHttpSetRecvTimeOut
STUB_FUNC 0x47940436,sceHttpSetResolveTimeOut
STUB_FUNC 0x4CC7D78F,sceHttpGetStatusCode
STUB_FUNC 0x9988172D,sceHttpSetSendTimeOut
STUB_FUNC 0x9B1F1F36,sceHttpCreateTemplate
STUB_FUNC 0xAB1ABE07,sceHttpInit
STUB_FUNC 0xB509B09E,sceHttpCreateRequestWithURL
STUB_FUNC 0xBB70706F,sceHttpSendRequest
STUB_FUNC 0xCDF8ECB9,sceHttpCreateConnectionWithURL
STUB_END

I'll be adding libhttp to the SDK soon, I'm working on it currently.
It's just a wrapper for the socket functions anyway, |

| There's also curl in the repo. Getting files across the net with curl is pretty simple. |

Now my makefile, i sorta adapt this makefile to everything so it may be wrong as usual, im using the kernels 3.XX or 1.50 either one. atm im using the 3.XX
| Code: | TARGET = DL_File
OBJS = main.o HttpRequest.o HttpPacket.o HttpResponse.o
INCDIR =
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
LIBDIR =
LIBS = sceHttp.S -lpsppower -lpspgu -lz -lm -lpspwlan sceWlanDrv_lib.S sceWlanDrv.S
LDFLAGS =
PSP_FW_VERSION = 340
BUILD_PRX = 1
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = DL_File
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak
|
I know im going wrong, just can't correct it, It compiles for me, but doesnt load now? it gets past the gameboot then....Black Screen. Idea's anyone.
i also tried in user,
| Code: | PSP_MODULE_INFO("DL_File", 0, 1, 1);
PSP_MAIN_THREAD_ATTR(PSP_THREAD_ATTR_USER); |
Do i need to add more stuff??, take stuff out, lol. |

You have to define Heap size:
| Code: | | PSP_HEAP_SIZE_MAX(); |
put it after psp module info.Should help. |

can you use a TCP/IP Socket to get files from the internet instead of a UDP(since it loses data). Just wondering because I have seen examples on how to get HTML data from a webserver but it was through UDP...

hmm... well you should try to go with Cygwin if you want easy updates.. Cygwin lets you install libs and update the SDK easily.. downside to installing Cygwin and toolchain is it takes forever.. but after that it works fine.

If you get errors saying no make file then add ./bootstrap then type the above commands.
It's in the Read Me that comes with the sdk. |

Install Nanodesktop. In 3 rows of code you can download what you
want.... |

You use them the same way you would if you weren't on a PSP.
Seriously, folks, some of y'all need some refresher courses on programming, and we don't do that here. |

i'm bad in english. i still don't know what you mean.
there is no psphttp.h in my pspsdk include dir.
may be it's not the latest one.
where can i find your psphttp.h and the lib.
thank you very much. |

it loaded until i added libhttp functions. i also tried a prx which worked until it reached the http functions, moonlight has to be right about the global variable. im guna try it again when i get a working app. |
