我正在尝试将整个流(多行)读入一个字符串.
I'm trying to read an entire stream (multiple lines) into a string.
我正在使用这段代码，它可以工作，但它冒犯了我的风格……当然有更简单的方法吗?也许使用字符串流?
I'm using this code, and it works, but it's offending my sense of style... Surely there's an easier way? Maybe using stringstreams?
void Obj::loadFromStream(std::istream & stream)
{
std::string s;
std::streampos p = stream.tellg(); // remember where we are
stream.seekg(0, std::ios_base::end); // go to the end
std::streamoff sz = stream.tellg() - p; // work out the size
stream.seekg(p); // restore the position
s.resize(sz); // resize the string
stream.read(&s[0], sz); // and finally, read in the data.
<小时>实际上，对字符串的 const 引用也可以，这可能会使事情变得更容易...
const reference to a string would do as well, and that may make things easier...
const std::string &s(... a miracle occurs here...)
怎么样
std::istreambuf_iterator<char> eos;
std::string s(std::istreambuf_iterator<char>(stream), eos);
(如果不是 MVP 可能是单线)
(could be a one-liner if not for MVP)
2011 年之后的编辑，这种方法现在拼写
post-2011 edit, this approach is now spelled
std::string s(std::istreambuf_iterator<char>(stream), {});
