following command in bash:\n\n```\ncd nacos-sdk-cpp\ncmake .\nmake\n```\n\na libnacos-cli.so and a nacos-cli.out will be generated\n\nrun `./nacos-cli.out` to perform test on the library\n\nrun `make install` to install the libnacos-cli to your system library path\n\n**Note:** You need to run a nacos server on your local machine listening on port 8848 to go through the whole test\nOne of the testcases will test endpoint functionality, so **you also need** to run a simple http server on port 80 which provides the following content:\n\n`127.0.0.1:8848`\n\n**on path /nacos/endpoint0**\n\n**All these examples could be found in nacos-sdk-cpp/examples/**\n\n## Integrate the library into your project\n\nHere is an example showing how to integrate the library(.so) into your project:\n\nIntegratingIntoYourProject.cpp:\n```C++\n#include \n#include \"Nacos.h\"\n\nusing namespace std;\nusing namespace nacos;\n\nint main() {\n Properties props;\n props[PropertyKeyConst::SERVER_ADDR] = \"127.0.0.1:8848\";//Server address\n NacosServiceFactory *factory = new NacosServiceFactory(props);\n ResourceGuard _guardFactory(factory);\n ConfigService *n = factory->CreateConfigService();\n ResourceGuard _serviceFactory(n);\n NacosString ss = \"\";\n try {\n ss = n->getConfig(\"k\", NULLSTR, 1000);\n }\n catch (NacosException &e) {\n cout <<\n \"Request failed with curl code:\" << e.errorcode() << endl <<\n \"Reason:\" << e.what() << endl;\n return -1;\n }\n cout << ss << endl;\n\n return 0;\n}\n\n```\n\n`g++ -I/usr/local/include/nacos/ IntegratingIntoYourProject.cpp -lnacos-cli -o integrated.out`\n\nStart a nacos on your localmachine listening on port 8848, and run `./integrated.out`\n\nThen you'll see:\n\n`SuccessfullyIntegrated`\n\n## If you are using a static lib(.a):\nAssume that the file you are compiling resides in the same directory as the .a library, please use the following command:\n\n`g++ -I/usr/local/include/nacos/ IntegratingIntoYourProject.cpp -lcurl -lz -L. -lnacos-cli-static -o integrated.out`\n\n-lcurl -lz Specifies the curl and lz library used by libnacos\n\n-L.

examples above to enable authentication:\n\n```C++\nusing namespace nacos;\n......\n configProps[PropertyKeyConst::SERVER_ADDR] = \"127.0.0.1\";\n configProps[PropertyKeyConst::AUTH_USERNAME] = \"username\";\n configProps[PropertyKeyConst::AUTH_PASSWORD] = \"password\";\n NacosServiceFactory *factory = new NacosServiceFactory(configProps);\n ConfigService *n = factory->CreateConfigService();\n NamingService *namingSvc = factory->CreateNamingService();\n......\n```\n\n### Enabling SPAS Authentication\n\n```C++\nusing namespace nacos;\n......\n configProps[PropertyKeyConst::SERVER_ADDR] = \"127.0.0.1\";\n configProps[PropertyKeyConst::ACCESS_KEY] = \"accessKey\";\n configProps[PropertyKeyConst::SECRET_KEY] = \"secretKey\";\n

(official site: [http://nacos.io](http://nacos.io)) is an easy-to-use platform designed for dynamic service discovery and configuration and service management. It helps you to build cloud native applications and microservices platform easily.\n\nService is a first-class citizen in Nacos. Nacos supports almost all type of services, for example: [Dubbo/gRPC service](https://nacos.io/en-us/docs/use-nacos-with-dubbo.html), [Spring Cloud RESTFul service](https://nacos.io/en-us/docs/use-nacos-with-springcloud.html) and [Kubernetes service](https://nacos.io/en-us/docs/use-nacos-with-kubernetes.html).\n" }, { "path": "README_zh_CN.md",

.\nmake\n```\n\n将会产生一个libnacos-cli.so 和一个 nacos-cli.out\n\n运行 `./nacos-cli.out` 以执行客户端的所有testcase\n\n运行 `make install` 将libnacos-cli安装到lib目录\n\n**注意:** 你需要在本机运行一个nacos server，监听8848端口以完成所有测试\n其中有个测试将会测试端点（endpoint）功能，**所以你还需要**在本机运行一个http服务器，在路径/endpoints/endpoint0提供下述内容：\n\n`127.0.0.1:8848`\n\n**这些例子你都能在nacos-sdk-cpp/examples/找到**\n\n##

`./integrated.out`\n\n你将会看到:\n\n`SuccessfullyIntegrated`\n\n## 如果你使用静态库(.a)链接\n假设.a文件和待编译文件在同一目录, 请执行下述命令:\n\n`g++ -I/usr/local/include/nacos/ IntegratingIntoYourProject.cpp -lcurl -lz -L. -lnacos-cli-static -o integrated.out`\n\n使用-lcurl -lz指定nacos客户端使用的curl和lz库\n\n使用-L. -lnacos-cli-static引用当前目录下的libnacos-cli-static.a\n\n## 配置\n\n### 获取配置\n\ngetConfig.cpp:\n```C++\n#include \n#include

Brown \nStill 100% Public Domain\n\nCorrected a problem which generated improper hash values on 16 bit machines\nRoutine SHA1Update changed from\n\tvoid SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned int\nlen)\nto\n\tvoid SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned\nlong len)\n\nThe 'len' parameter was declared an int which works fine on 32 bit machines.\nHowever, on 16 bit machines an int is too small for the shifts being done\nagainst\nit. This caused the hash function to generate incorrect values if len was\ngreater than 8191 (8K - 1) due to the 'len << 3' on line 3 of SHA1Update().\n\nSince the file IO in main() reads 16K at a time, any file 8K or larger would\nbe guaranteed to generate the wrong hash (e.g. Test Vector #3, a million\n\"a\"s).\n\nI also changed the declaration of variables i & j in SHA1Update to\nunsigned long from unsigned int for the same reason.\n\nThese changes should make no difference to any 32 bit implementations since\nan\nint and a long are the same size in those environments.\n\n--\nI also corrected a few compiler warnings generated by Borland C.\n1. Added #include for exit() prototype\n2. Removed unused variable 'j' in SHA1Final\n3.

It can simplify coding of DOM tree manipulation, because it\n can access multiple-level depth of DOM tree with single API call.\n\n After it parses a string representation (e.g. \"/foo/0\" or URI fragment \n representation (e.g. \"#/foo/0\") into its internal representation (tokens),\n it can be used to resolve a specific value in multiple documents, or sub-tree \n of documents.\n\n Contrary to GenericValue, Pointer can be copy constructed and copy assigned.\n Apart from assignment, a Pointer cannot be modified after construction.\n\n Although Pointer is very convenient, please aware that constructing Pointer\n involves parsing and dynamic memory allocation. A special constructor with user-\n supplied tokens eliminates these.\n\n GenericPointer depends on GenericDocument and GenericValue.\n \n \\tparam ValueType The value type of the DOM tree. E.g. GenericValue >\n \\tparam Allocator The allocator type for allocating memory for internal representation.\n \n \\note GenericPointer uses same encoding of ValueType.\n However, Allocator of GenericPointer is independent of Allocator of Value.\n*/\ntemplate \nclass GenericPointer {\npublic:\n typedef typename ValueType::EncodingType EncodingType; //!< Encoding type from Value\n typedef typename ValueType::Ch Ch; //!< Character type from Value\n\n //!
