對於我的C++項目，我使用名爲libmsgpack-dev的Ubuntu（14.04）標準存儲庫中提供的c + + msgpack庫。Msgpack packing bools bug
除了當我嘗試打包一些布爾時，所有的工作都很好。有些東西絕對是香蕉。首先我寫了簡單的測試來研究pack方法。原來，它不能被信任包裝布爾。下面是簡單的測試顯示的問題：
#include <msgpack.hpp>
TEST_CASE("bool packing", "[msgpack1]") {
msgpack::sbuffer buf;
msgpack::packer<msgpack::sbuffer> p(&buf);
std::string key = "BoolValue";
bool value = true;
p.pack_map(1);
{
p.pack(key);
p.pack(value);
}
msgpack::unpacked msg;
msgpack::unpack(&msg, buf.data(), buf.size());
std::map<std::string, msgpack::object> m;
msg.get().convert(&m);
bool loaded_value;
m.at(key).convert(&loaded_value);
INFO("We packed: " << value);
INFO("We loaded: " << loaded_value);
REQUIRE(value == loaded_value);
}
與結果：
unit_tests/unit_msgpack.cpp:30: FAILED:
REQUIRE(value == loaded_value)
with expansion:
true == false
with messages:
We packed: 1
We loaded: 0
我想好了，是有沒有解決辦法？是的，我發現了方法pack_true和pack_false。對，爲了打包bools，我只需要明確地調用這兩個函數，它就可以正常工作。但不是。對於這個測試：
TEST_CASE("bool packing two elements", "[msgpack2]") {
msgpack::sbuffer buf;
msgpack::packer<msgpack::sbuffer> p(&buf);
std::string key1 = "BoolValue1";
std::string key2 = "BoolValue2";
bool value1 = false;
bool value2 = true;
p.pack_map(2);
{
p.pack(key1);
if (value1) {
p.pack_true();
} else {
p.pack_false();
}
p.pack(key2);
if (value2) {
p.pack_true();
} else {
p.pack_false();
}
}
msgpack::unpacked msg;
msgpack::unpack(&msg, buf.data(), buf.size());
std::map<std::string, msgpack::object> m;
msg.get().convert(&m);
bool loaded_value1;
bool loaded_value2;
m.at(key1).convert(&loaded_value1);
m.at(key2).convert(&loaded_value2);
INFO("We packed: " << value1 << " : " << value2);
INFO("We loaded: " << loaded_value1 << " : " << loaded_value2);
REQUIRE((value1 == loaded_value1 && value2 == loaded_value2));
}
我得到以下結果：
unit_tests/unit_msgpack.cpp:72: FAILED:
REQUIRE((value1 == loaded_value1 && value2 == loaded_value2))
with expansion:
false
with messages:
We packed: 0 : 1
We loaded: 0 : 0
是否有人可以幫助我的嗎？在圖書館有沒有錯誤，或者我做錯了什麼？
