C++读取管道分隔文件

我有这个信息的file1.txt

4231650|A|4444
4225642|A|5555

我在这里检查了如何在C++中读取管道分隔文件

C++ Read file line by line then split each line using the delimiter

我根据自己的需要修改了一点代码。问题是它可以读取第一个管道,但之后如何读取其余值?

这是我的代码:

std::ifstream file("file1.txt");
    std::string   line;

    while(std::getline(file, line))
    {
        std::stringstream   linestream(line);
        std::string         data;
        std::string         valStr1;
        std::string         valStr2;


        std::getline(linestream, data, '|');  // read up-to the first pipe

        // Read rest of the pipe values? Why did the accepted answer worked for int but not string???
        linestream >> valStr1 >> valStr2;

        cout << "data: " <<  data << endl;
        cout << "valStr1: " <<  valStr1 << endl;
        cout << "valStr2: " <<  valStr2 << endl;
    }

输出如下:
