我试过std :: string(),但是我收到了一个错误。 码: temp_doc.uuid = std::string(sqlite3_column_text(this->stmts.read_documents, 0)); 错误: 1>.storage_manager.cpp(109) : error C2440: '<function-style-cast>' : cannot convert from 'const unsigned char *' to 'std::string' 1> No...
将std::string转换为const char *和函数调用 将std字符串转换为const char* 错误:将‘const string {aka const std::__cxx11::basic_string<char>}’作为‘this’参数传递 将const std::vector<char>转换为unsigned char*? 直接从char*返回std::string ...
将const uint8_t []转换为std::string可以通过以下方式实现: 使用std::string的构造函数:可以直接使用std::string的构造函数将const uint8_t []转换为std::string。例如: 代码语言:txt 复制 const uint8_t data[] = {65, 66, 67, 0}; // 示例数据 std::string str(reinterpret_cast<const ...

有无const变量互转,有无unsigned变量互转 1.去掉unsigned: unsigned char* aaa; reinterpret_cast<char*>(aaa); 2.去掉const: const char* aaa; const_cast<char*>(aaa); 3.加上unsigned、const: 括号强转就行。 4. 也可通过static_cast强制转换...

std::string(或 const char*)转换为 const unsigned char*? 这是发送代码: for (int ix = 0; ix < m_numMessages; ++ix) { // Create a CsgNode object from the protobuf class csgBox csgNode; csgNode.set_n("box"); csgNode.set_h(1600.0f); csgNode.set_l(1600.0f); csgNode.set...
