WTF:String 转std:string

这里提供了三个方法将WTF中的String类型转换为std::string类型:
1. 使用ws2s函数,将wstring类型转换为char*类型,再转换为std::string类型。
2. 使用s2ws函数,将std::string类型转换为wchar_t*类型,再转换为wstring类型,最后使用wstring的.c_str()函数获取const wchar_t*类型,再使用wcstombs函数将其转换为char*类型,最终转换为std::string类型。
3. 使用s2ws函数,将std::string类型转换为wstring类型,再使用wstring的.c_str()函数获取const wchar_t*类型,最后使用wcstombs函数将其转换为char*类型,最终转换为std::string类型。

WTF string
WTF string是一个在Web技术框架中使用的字符串类。它是由KURL.string()方法返回的String类的一个实例,并具有utf8()成员函数。String类定义在wtf/text/WTFString.h头文件中。此外,String类还有一个utf8()成员函数,它返回一个CString类的实例。CString类定义在wtf/text/CString.h头文件中,并具有data()成员函数。因此,如果想要获取KURL中的字符数组(char *),可以通过调用KURL.string().utf8().data()来实现。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
