• STN: a signaling network component, the major part of Mars.

Samples

Start with sample usage here.

Getting started

Choose Android or iOS/OS X or Windows.

Android

You can use either mars-wrapper or mars-core. We recommend you to use mars-wrapper when you just wanna build a sample or demo, while mars-core is preferred to be used in your APP.

mars-wrapper

Add dependencies by adding the following lines to your app/build.gradle.

dependencies {
    compile 'com.tencent.mars:mars-wrapper:1.2.3'
}

OR

mars-core

Add dependencies by adding the following lines to your app/build.gradle.

dependencies {
    compile 'com.tencent.mars:mars-core:1.2.3'
}

OR

mars-xlog

If you just want to user xlog, add dependencies by adding the following lines to your app/build.gradle. note: xlog is included in mars-core and mars-wrapper.

dependencies {
    compile 'com.tencent.mars:mars-xlog:1.2.3'
}

If you read here, make sure you have added dependencies of mars-wrapper, mars-core or mars-xlog.

Xlog Init

Initialize Xlog when your APP starts. Remember to use an exclusive folder to save the log files, no other files are acceptable in the folder since they would be removed by the cleansing function in Xlog automatically.

When multiple processes is used in your app, make sure that each process owns its exclusive log file.

System.loadLibrary("c++_shared");
System.loadLibrary("marsxlog");

final String SDCARD = Environment.getExternalStorageDirectory().getAbsolutePath();
final String logPath = SDCARD + "/marssample/log";

// this is necessary, or may crash for SIGBUS
final String cachePath = this.getFilesDir() + "/xlog"

//init xlog
if (BuildConfig.DEBUG) {
    Xlog.appenderOpen(Xlog.LEVEL_DEBUG, Xlog.AppenderModeAsync, cachePath, logPath, "MarsSample", 0, "");
    Xlog.setConsoleLogOpen(true);

} else {
    Xlog.appenderOpen(Xlog.LEVEL_INFO, Xlog.AppenderModeAsync, cachePath, logPath, "MarsSample", 0, "");
    Xlog.setConsoleLogOpen(false);
}

Log.setLogImp(new Xlog());

Uninitialized Xlog when your app exits

Log.appenderClose();

STN Init

If you add dependencies of mars-core to your project, you need to initialize and release STN. Initialize STN before you use it

// set callback
AppLogic.setCallBack(stub);
StnLogic.setCallBack(stub);
SdtLogic.setCallBack(stub);

// Initialize the Mars PlatformComm
Mars.init(getApplicationContext(), new Handler(Looper.getMainLooper()));

// Initialize the Mars
StnLogic.setLonglinkSvrAddr(profile.longLinkHost(), profile.longLinkPorts());
StnLogic.setShortlinkSvrAddr(profile.shortLinkPort());
StnLogic.setClientVersion(profile.productID());
Mars.onCreate(true);

BaseEvent.onForeground(true);
StnLogic.makesureLongLinkConnected();

Firstly, you should call the setCallBack interface, and secondly, the Mars.init. Then, to initialize the Mars, there is to need to strictly follow the orders of the four commands. Finally, after Mars are initialized, onForeground and makesureLongLinkConnect can be called.

Destroy STN or exit your app:

Mars.onDestroy();

Event Change

Network change:

BaseEvent.onNetworkChange()

---

If you add dependencies of mars-wrapper to your project, you just need initialize STN and no need uninitialized.

MarsServiceProxy.init(this, getMainLooper(),null);

---

No matter which way of dependencies you used, you must pay attention to these.

The state (background or foreground) of the APP is changed:

BaseEvent.onForeground(boolean);

The account of the APP is changed:

StnLogic.reset();

If you want to modify the encryption algorithm of Xlog, the packer/unpacker of longlink/shortlink, or you want to define the other components by yourself, refer here

iOS/OS X

Compile

python build_ios.py

or

python build_osx.py

1. Add mars.framework as a dependency of your project.
2. Rename files in mars/libraries/mars_android_sdk/jni with .rewriteme extension to .cc extension.
3. Add header files in mars/libraries/mars_android_sdk/jni and source files from step 2 into your project.

Xlog Init

Initialize Xlog when your app starts. Remember to use an exclusive folder to save the log files, no other files are acceptable in the folder since they would be removed by the cleansing function in Xlog automatically.

NSString* logPath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingString:@"/log"];

// set do not backup for logpath
const char* attrName = "com.apple.MobileBackup";
u_int8_t attrValue = 1;
setxattr([logPath UTF8String], attrName, &attrValue, sizeof(attrValue), 0, 0);

// init xlogger
#if DEBUG
xlogger_SetLevel(kLevelDebug);
appender_set_console_log(true);
#else
xlogger_SetLevel(kLevelInfo);
appender_set_console_log(false);
#endif
appender_open(kAppednerAsync, [logPath UTF8String], "Test",  0, "");

Close xlog in function "applicationWillTerminate"

appender_close();

STN Init

Initialize STN before you use it:

- (void)setCallBack {
    mars::stn::SetCallback(mars::stn::StnCallBack::Instance());
    mars::app::SetCallback(mars::app::AppCallBack::Instance());
}

- (void) createMars {
    mars::baseevent::OnCreate();
}

- (void)setClientVersion:(UInt32)clientVersion {
    mars::stn::SetClientVersion(clientVersion);
}

- (void)setShortLinkDebugIP:(NSString *)IP port:(const unsigned short)port {
    std::string ipAddress([IP UTF8String]);
    mars::stn::SetShortlinkSvrAddr(port, ipAddress);
}

- (void)setShortLinkPort:(const unsigned short)port {
    mars::stn::SetShortlinkSvrAddr(port);
}

- (void)setLongLinkAddress:(NSString *)string port:(const unsigned short)port debugIP:(NSString *)IP {
    std::string ipAddress([string UTF8String]);
    std::string debugIP([IP UTF8String]);
    std::vector<uint16_t> ports;
    ports.push_back(port);
    mars::stn::SetLonglinkSvrAddr(ipAddress,ports,debugIP);
}

- (void)setLongLinkAddress:(NSString *)string port:(const unsigned short)port {
    std::string ipAddress([string UTF8String]);
    std::vector<uint16_t> ports;
    ports.push_back(port);
    mars::stn::SetLonglinkSvrAddr(ipAddress,ports);
}

- (void)reportEvent_OnForeground:(BOOL)isForeground {
    mars::baseevent::OnForeground(isForeground);
}

- (void)makesureLongLinkConnect {
    mars::stn::MakesureLonglinkConnected();
}

Firstly, you should call the setCallBack interface, and secondly, the Mars.init. Then, to initialize the Mars, there is to need to strictly follow the orders of the four commands. Finally, after Mars are initialized, onForeground and makesureLongLinkConnect can be called.

If you want to destroy STN or exit App:

- (void)destroyMars {
    mars::baseevent::OnDestroy();
}

Event Change

When the App's state of background or foreground is changed:

- (void)reportEvent_OnForeground:(BOOL)isForeground {
    mars::baseevent::OnForeground(isForeground);
}

Network change:

- (void)reportEvent_OnNetworkChange {
    mars::baseevent::OnNetworkChange();
}

Windows

Install Visual Studio 2015.

Compile

python build_windows.py

2. Rename files in mars/libraries/mars_android_sdk/jni with .rewriteme extension to .cc extension.
3. Add header files in mars/libraries/mars_android_sdk/jni and source files from step 2 into your project.

Xlog Init

Initialize Xlog when your app starts. Remember to use an exclusive folder to save the log files, no other files are acceptable in the folder since they would be removed by the cleansing function in Xlog automatically.

std::string logPath = ""; //use your log path
std::string pubKey = ""; //use you pubkey for log encrypt

// init xlog
#if DEBUG
xlogger_SetLevel(kLevelDebug);
appender_set_console_log(true);
#else
xlogger_SetLevel(kLevelInfo);
appender_set_console_log(false);
#endif
appender_open(kAppednerAsync, logPath.c_str(), "Test", 0, pubKey.c_str());

Uninitialized xlog before your app exits

appender_close();

{
	mars::stn::SetShortlinkSvrAddr(_port, _ip);
}
void setShortLinkPort(unsigned short _port)
{
	mars::stn::SetShortlinkSvrAddr(_port, "");
}
void setLongLinkAddress(const std::string& _ip, unsigned short _port, const std::string& _debug_ip)
{
	vector<uint16_t> ports;

Mars

Mars 是微信官方的跨平台跨业务的终端基础组件。

• comm：可以独立使用的公共库，包括 socket、线程、消息队列、协程等；
• xlog：高可靠性高性能的运行期日志组件；
• SDT： 网络诊断组件；
• STN： 信令分发网络模块，也是 Mars 最主要的部分。

Samples

sample 的使用请参考这里。

Getting started

接入 Android 或者 iOS/OS X 或者 Windows 。

Android

gradle 接入我们提供了两种接入方式：mars-wrapper 或者 mars-core。如果你只是想做个 sample 推荐使用 mars-wrapper，可以快速开发；但是如果你想把 mars 用到你的 app 中的话，推荐使用 mars-core，可定制性更高。

mars-wrapper

在 app/build.gradle 中添加 mars-wrapper 的依赖：

dependencies {
    compile 'com.tencent.mars:mars-wrapper:1.2.3'
}

或者

mars-core

在 app/build.gradle 中添加 mars-core 的依赖：

dependencies {
    compile 'com.tencent.mars:mars-core:1.2.3'
}

或者

mars-xlog

如果只想使用 xlog,可以只加 xlog 的依赖(mars-core,mars-wrapper 中都已经包括 xlog)：

dependencies {
    compile 'com.tencent.mars:mars-xlog:1.2.3'
}

接着往下操作之前，请先确保你已经添加了 mars-wrapper 或者 mars-core 或者 mars-xlog 的依赖

Xlog Init

在程序启动加载 Xlog 后紧接着初始化 Xlog。但要注意如果你的程序使用了多进程，不要把多个进程的日志输出到同一个文件中，保证每个进程独享一个日志文件。而且保存 log 的目录请使用单独的目录，不要存放任何其他文件防止被 xlog 自动清理功能误删。

System.loadLibrary("c++_shared");
System.loadLibrary("marsxlog");

final String SDCARD = Environment.getExternalStorageDirectory().getAbsolutePath();
final String logPath = SDCARD + "/marssample/log";

// this is necessary, or may crash for SIGBUS
final String cachePath = this.getFilesDir() + "/xlog"

//init xlog
if (BuildConfig.DEBUG) {
    Xlog.appenderOpen(Xlog.LEVEL_DEBUG, Xlog.AppenderModeAsync, cachePath, logPath, "MarsSample", 0, "");
    Xlog.setConsoleLogOpen(true);

} else {
    Xlog.appenderOpen(Xlog.LEVEL_INFO, Xlog.AppenderModeAsync, cachePath, logPath, "MarsSample", 0, "");
    Xlog.setConsoleLogOpen(false);
}

Log.setLogImp(new Xlog());

程序退出时关闭日志：

Log.appenderClose();

STN Init

如果你是把 mars-core 作为依赖加入到你的项目中的话，你需要显式的初始化和反初始化 STN

在使用 STN 之前进行初始化

// set callback
AppLogic.setCallBack(stub);
StnLogic.setCallBack(stub);
SdtLogic.setCallBack(stub);

// Initialize the Mars PlatformComm
Mars.init(getApplicationContext(), new Handler(Looper.getMainLooper()));

// Initialize the Mars
StnLogic.setLonglinkSvrAddr(profile.longLinkHost(), profile.longLinkPorts());
StnLogic.setShortlinkSvrAddr(profile.shortLinkPort());
StnLogic.setClientVersion(profile.productID());
Mars.onCreate(true);
BaseEvent.onForeground(true);

StnLogic.makesureLongLinkConnected();

初始化顺序不一定要严格遵守上述代码的顺序，但在初始化时首先要调用 setCallBack 接口 (callback 文件的编写可以参考 demo)，再调用 Mars.init，最后再调用 onForeground 和 makesureLongLinkConnect，中间顺序可以随意更改。注意：STN 默认是后台，所以初始化 STN 后需要主动调用一次BaseEvent.onForeground(true)

需要释放 STN 或者退出程序时:

Mars.onDestroy();

Event Change

网络切换时:

BaseEvent.onNetworkChange()

---

如果你是把 mars-wrapper 作为依赖加入到你的项目中，你只需要显式的初始化 STN，不需要反初始化(因为 mars-wrapper 会进行反初始化)

MarsServiceProxy.init(this, getMainLooper(),null);

---

不管你是使用 mars-wrapper 还是 mars-core，你都需要特别注意以下事件：

前后台切换:

BaseEvent.onForeground(boolean);

应用的账号信息更改:

StnLogic.reset();

如果你想修改 Xlog 的加密算法或者长短连的加解包部分甚至更改组件的其他部分，可以参考这里

iOS/OS X

编译

python build_ios.py

or

python build_osx.py

把 mars.framework 作为依赖加入到你的项目中，把mars/libraries/mars_android_sdk/jni 目录的后缀名为 rewriteme 的文件名删掉".rewriteme"和头文件一起加入到你的项目中。

Xlog Init

在程序启动加载 Xlog 后紧接着初始化 Xlog。但要注意保存 log 的目录请使用单独的目录，不要存放任何其他文件防止被 xlog 自动清理功能误删。

NSString* logPath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingString:@"/log"];

// set do not backup for logpath
const char* attrName = "com.apple.MobileBackup";
u_int8_t attrValue = 1;
setxattr([logPath UTF8String], attrName, &attrValue, sizeof(attrValue), 0, 0);

// init xlogger
#if DEBUG
xlogger_SetLevel(kLevelDebug);
appender_set_console_log(true);
#else
xlogger_SetLevel(kLevelInfo);
appender_set_console_log(false);
#endif
appender_open(kAppednerAsync, [logPath UTF8String], "Test",  0, "");

在函数 "applicationWillTerminate" 中反初始化 Xlog

appender_close();

STN Init

在你用 STN 之前初始化：

    mars::stn::SetShortlinkSvrAddr(port);
}

- (void)setLongLinkAddress:(NSString *)string port:(const unsigned short)port debugIP:(NSString *)IP {

    std::string debugIP([IP UTF8String]);
    std::vector<uint16_t> ports;
    ports.push_back(port);
    mars::stn::SetLonglinkSvrAddr(ipAddress,ports,debugIP);
}

- (void)setLongLinkAddress:(NSString *)string port:(const unsigned short)port {
    std::string ipAddress([string UTF8String]);
    std::vector<uint16_t> ports;
    ports.push_back(port);
    mars::stn::SetLonglinkSvrAddr(ipAddress,ports);
}

- (void)reportEvent_OnForeground:(BOOL)isForeground {
    mars::baseevent::OnForeground(isForground);
}

- (void)makesureLongLinkConnect {
    mars::stn::MakesureLonglinkConnected();
}

初始化顺序不一定要严格遵守上述代码的顺序，但在初始化时首先要调用 setCallBack 接口 (callback 文件的编写可以参考 demo)，再调用 Mars.init，最后再调用 onForeground 和 makesureLongLinkConnect，中间顺序可以随意更改。注意：STN 默认是后台，所以初始化 STN 后需要主动调用一次BaseEvent.onForeground(true)

需要释放 STN 或者退出程序时:

    mars::baseevent::OnDestroy();
}

Event Change

前后台切换时:

- (void)reportEvent_OnForeground:(BOOL)isForeground {
    mars::baseevent::OnForeground(isForeground);
