kotlin-mpp-wininet - Cookie Handle

how to get the cookie returned by a Http get?

[vaclavhodek]

You have to use HttpQueryInfoW with HTTP_QUERY_COOKIE to get the corresponding header.

There's no built-in solution for handling cookies out-of-the-box. The same applies for setting cookies. You need to send Set-Cookie header manually.

Ty, HttpQueryInfoW worked fine for me,

justed added this code in "WinInetHelper.request", after getResponseData() call

sample:
var lpszData = ByteArray(200)
val dwSize = alloc()
val index = alloc()
index.value = 0.dword()
dwSize.value = 200.dword()
lpszData.usePinned {
if (HttpQueryInfoW(requestHandle.handle,HTTP_QUERY_SET_COOKIE,it.addressOf(0),dwSize.ptr,index.ptr) == 0){
if (GetLastError().toInt() == ERROR_INSUFFICIENT_BUFFER){
println("ERROR_INSUFFICIENT_BUFFER, required_size = " + dwSize.value)
lpszData = ByteArray(dwSize.value.toInt())
index.value = 0.dword()
HttpQueryInfoW(requestHandle.handle,HTTP_QUERY_SET_COOKIE,it.addressOf(0),dwSize.ptr,index.ptr)
}
else if (GetLastError().toInt() == ERROR_HTTP_HEADER_NOT_FOUND){
index.value = 0.dword()
HttpQueryInfoW(requestHandle.handle,HTTP_QUERY_COOKIE,it.addressOf(0),dwSize.ptr,index.ptr)
println("ERROR_HTTP_HEADER_NOT_FOUND (HTTP_QUERY_SET_COOKIE) - trying HTTP_QUERY_COOKIE")
}
}
}
println("size = " + dwSize.value + ", indice = " + index.value + ", cookie = " + lpszData.decodeToString())

Do you Know to to handle https with certificate? In java u should update sdk cacerts, no idea how to do it in klotin/native

[vaclavhodek]

HTTPS is supported by the WinInet library and handled transparently, so the certificate has to be available in system.

It's controller by INTERNET_FLAG_SECURE flag. Check MemScope.openRequest(...) function in WinInetHelper.kt.
