JSON Library Usage

Example:

 // Include header file
#include <json/json.h>

Json::Value root;
root["name"] = "plugin"; 
// Add array
root["array"].append("arr0"); 
root["array"].append("arr1"); 
// Nested object
root["obj"]["inner"] = 1; 
// Check if key exists
if (root.isMember("obj") && root["obj"].isObject() && root["obj"].isMember("inner") && 		root["obj"]["inner"].isInt()) {
    LOG(INFO)<< root["obj"]["inner"].asInt(); 
}
// Process array field
if (root.isMember("array") && root["array"].isArray()) {
    for (const auto& item : root["array"]) {
        LOG(INFO)<<item.asString();
    }
}
// Serialize string
Json::StreamWriterBuilder writer; 
std::string str = Json::writeString(writer, root); 
LOG(INFO) << "json string:\n" << str ;

For more advanced usage of the json library, please refer to the header file.
