我发现 0x1A 是 Substitute 但我不确定这意味着什么以及流读取停止的原因。我当然也想知道如何解决这个问题。
首先，我使用以下代码生成二进制文件:
unsigned char bytes[] = {
0xA1, 0x58, 0x02, 0x01, 0x03, 0x02, 0x01, 0x15, 0x30, 0x50, 0x55, 0x04, 0x02, 0x00, 0x00, 0x00,
0xA7, 0x48, 0xA0, 0x46, 0xA4, 0x44, 0xA7, 0x42, 0x04, 0x40, 0x8A, 0x00, 0x35, 0x2C, 0x77, 0x58,
0x83, 0xE9, 0x78, 0x9F, 0x4F, 0x34, 0x06, 0xE1, 0xB2, 0x57, 0x3A, 0x0C, 0xEF, 0x18, 0x54, 0x54,
0x1A, 0x4D, 0xBF, 0x2D, 0x02, 0x36, 0x18, 0xCB, 0x4A, 0xC3, 0x58, 0x20, 0xFC, 0x92, 0xDE, 0xBC,
0x85, 0x94, 0x90, 0x27, 0x36, 0x05, 0xEA, 0xE5, 0xEA, 0xE6, 0x0B, 0x73, 0xEF, 0xD1, 0x9E, 0x85,
0x38, 0x57, 0x1E, 0xF6, 0x62, 0x9B, 0x8F, 0x74, 0xA3, 0x00 };
const size_t sz = sizeof(bytes) / sizeof(bytes[0]);
std::ofstream fstrm("binfile.bin", std::ofstream::binary);
std::for_each(bytes, bytes + sz, [&](const char ch) {
fstrm.put(ch);
});
fstrm.close();
然后我使用 C++ 标准库 IO 函数来读取流，如下所示:
#include <iostream>
#include <iterator> // std::istream_iterator
#include <algorithm>
int main() {
unsigned char bytes[] = {
0xA1, 0x58, 0x02, 0x01, 0x03, 0x02, 0x01, 0x15, 0x30, 0x50, 0x55, 0x04, 0x02, 0x00, 0x00, 0x00,
0xA7, 0x48, 0xA0, 0x46, 0xA4, 0x44, 0xA7, 0x42, 0x04, 0x40, 0x8A, 0x00, 0x35, 0x2C, 0x77, 0x58,
0x83, 0xE9, 0x78, 0x9F, 0x4F, 0x34, 0x06, 0xE1, 0xB2, 0x57, 0x3A, 0x0C, 0xEF, 0x18, 0x54, 0x54,
0x1A, 0x4D, 0xBF, 0x2D, 0x02, 0x36, 0x18, 0xCB, 0x4A, 0xC3, 0x58, 0x20, 0xFC, 0x92, 0xDE, 0xBC,
0x85, 0x94, 0x90, 0x27, 0x36, 0x05, 0xEA, 0xE5, 0xEA, 0xE6, 0x0B, 0x73, 0xEF, 0xD1, 0x9E, 0x85,
0x38, 0x57, 0x1E, 0xF6, 0x62, 0x9B, 0x8F, 0x74, 0xA3, 0x00 };
const size_t sz = sizeof(bytes) / sizeof(bytes[0]);
std::cout << "cout with array\n";
std::for_each(bytes, bytes+sz, [](unsigned char ch) {
std::cout << std::hex << (int)ch << ' ';
});
std::cout << "\n\n";
std::istream_iterator<unsigned char> eos; // end-of-stream iterator
std::istream_iterator<unsigned char> iit(std::cin); // stdin iterator
std::cout << "cout with stdin - redirecting file of same bytes as above\n";
std::for_each(iit, eos, [](unsigned char ch) {
std::cout << std::hex << (int)ch << ' ';
});
std::cout << '\n';
}
如果我这样调用我的程序:
myprog <binfile.bin
我得到的输出是:
cout with array
a1 58 2 1 3 2 1 15 30 50 55 4 2 0 0 0 a7 48 a0 46 a4 44 a7 42 4 40 8a 0 35 2c 77
58 83 e9 78 9f 4f 34 6 e1 b2 57 3a c ef 18 54 54 1a 4d bf 2d 2 36 18 cb 4a c3 5

8f 74 a3 0
cout with stdin - redirecting file of same bytes as above
a1 58 2 1 3 2 1 15 30 50 55 4 2 0 0 0 a7 48 a0 46 a4 44 a7 42 4 40 8a 0 35 2c 77
58 83 e9 78 9f 4f 34 6 e1 b2 57 3a ef 18 54 54
为什么输入读取在 0xA1 字符处停止？如何获取读取完整二进制文件的代码？
