返回文件\u stream::open\u istream(L“myfile.txt”)。然后([](pplx::task previousTask)

尝试
{
auto fileStream=previousTask.get();
//以文件流作为主体发出HTTP请求。

返回client.request(methods::PUT,L“myfile”,fileStream)。然后([fileStream](pplx::task previousTask)

标准:WOSS;
尝试
{
自动响应=previousTask.get();

ss“www.fourthcoffee.com”只是一个例子-它重定向到www.microsoft.com。您需要一个接受上载的服务器。在我的代码中,我更改了URI。它是一个应该支持PUT上载的服务器吗?是的,它支持。
