参数需要作为JSON数组传递。满足需求的最简单方法是：def
The following example shows how to use Boost.JSON to parse a JSON string: cpp. #include <boost/json.hpp>。 int main() {。 // Create a JSON string. std::string json_string = "{ \"name\": \"John Doe\", \"age\": 30 }"; // Parse the JSON string. boost::json::value json...
boost::json::value no_confused_json1 = {boost::json::array({"data","value"})};boost::json::value no_confused_json2 = boost::json::object({{"data","value"}}); 结果为: 解码# JSON的解码也比较简单。 简单的解码# autodecode_val = boost::json::parse("{\"123\": [1, 2, 3]}...
