JSON（JavaScript对象符号）是一种轻量级的数据交换格式。它可以是整数，实数，字符串，值的有序序列，名称/值对的集合。

是一个简单的API来操纵 JSON值，处理序列化和反序列化到字符串。在反序列化/序列化的步骤，它也可以保留现有的注释，一种方便的格式来存储用户输入的文件。

工程如图：

测试效果如图：

测试代码A：

int main( int argc,const char *argv[] )
{
   std::string path = "C:\\Users\\Administrator\\Desktop\\JsonCpp\\jsoncpp-src-0.6.0-rc2\\jsoncpp-src-0.6.0-rc2\\test\\data\\test_complex_01.json";
   Json::Features features;
   bool parSEOnly;
   //模拟测试参数
   argc = 2;
   argv[0] = "";
   argv[1] = "C:\\Users\\Administrator\\Desktop\\JsonCpp\\jsoncpp-src-0.6.0-rc2\\jsoncpp-src-0.6.0-rc2\\test\\data\\test_complex_01.json";

   //分析命令行参数
   int exitCode = parseCommandLine( argc,argv,features,path,parSEOnly );
   if ( exitCode != 0 )
   {
      return exitCode;
   }

   try
   {
	   //读取json文件
	   
	//   readInputTestFile 返回	"{ 
	//"count" : 1234,//"name" : { "aka" : "T.E.S.T.","id" : 123987 },//"attribute" : [ 
	//	"random",//	"short",//	"bold",//	12,//	{ "height" : 7,"width" : 64 } 
	//	],//"test": { "1" : 
	//	{ "2" : 
	//		{ "3" :  { "coord" : [ 1,2] } 
	//		} 
	//	}
	//}
	//}

      std::string input = readInputTestFile( path.c_str() );
      if ( input.empty() )
      {
         printf( "Failed to read input or empty input: %s\n",path.c_str() );
         return 3;
      }

      std::string basePath = removeSuffix( argv[1],".json" );
      if ( !parSEOnly  &&  basePath.empty() )
      {
         printf( "Bad input path. Path does not end with '.expected':\n%s\n",path.c_str() );
         return 3;
      }

      std::string actualPath = basePath + ".actual";
      std::string rewritePath = basePath + ".rewrite";
      std::string rewriteActualPath = basePath + ".actual-rewrite";

      Json::Value root;

	  //分析和保存树值
      exitCode = parseAndSaveValueTree( input,actualPath,"input",root,parSEOnly );
      if ( exitCode == 0  &&  !parSEOnly )
      {
         std::string rewrite;
         exitCode = rewriteValueTree( rewritePath,rewrite );
         if ( exitCode == 0 )
         {
            Json::Value rewriteRoot;
			
			//分析和保存树值
            exitCode = parseAndSaveValueTree( rewrite,rewriteActualPath,"rewrite",rewriteRoot,parSEOnly );
         }
      }
   }
   catch ( const std::exception &e )
   {
      printf( "Unhandled exception:\n%s\n",e.what() );
      exitCode = 1;
   }

   return exitCode;
}

测试代码B：

   JsonTest::Runner runner;
   JSONTEST_REGISTER_FIXTURE( runner,ValueTest,size );
   JSONTEST_REGISTER_FIXTURE( runner,isObject );
   JSONTEST_REGISTER_FIXTURE( runner,isArray );
   JSONTEST_REGISTER_FIXTURE( runner,isBool );
   JSONTEST_REGISTER_FIXTURE( runner,isInt );
   JSONTEST_REGISTER_FIXTURE( runner,isUInt );
   JSONTEST_REGISTER_FIXTURE( runner,isDouble );
   JSONTEST_REGISTER_FIXTURE( runner,isString );
   JSONTEST_REGISTER_FIXTURE( runner,isNull );
   JSONTEST_REGISTER_FIXTURE( runner,accessArray );
   JSONTEST_REGISTER_FIXTURE( runner,asFloat );
   JSONTEST_REGISTER_FIXTURE( runner,compareNull );
   JSONTEST_REGISTER_FIXTURE( runner,compareInt );
   JSONTEST_REGISTER_FIXTURE( runner,compareUInt );
   JSONTEST_REGISTER_FIXTURE( runner,compareDouble );
   JSONTEST_REGISTER_FIXTURE( runner,compareString );
   JSONTEST_REGISTER_FIXTURE( runner,compareBoolean );
   JSONTEST_REGISTER_FIXTURE( runner,compareArray );
   JSONTEST_REGISTER_FIXTURE( runner,compareObject );
   JSONTEST_REGISTER_FIXTURE( runner,compareType );
   return runner.runCommandLine( argc,argv );
