Firebreath NPAPI插件如何登录

Question

如何使用C++中的FireBreath构建的NPAPI插件输出日志消息。
日志在开发和测试期间和/或在Debug版本中应该可用。

---

修改：

的FireBreath地记录与Log4cplus，我试图尽可能接近我可以实现这些指令。
我将add_firebreath_library(log4cplus)添加到“PluginConfig.cmake”的底部。

我还没有能够创造，我可以在Windows 8.读我已经通过其他资源，比如这个浏览日志文件：FBLOG_TRACE() No logging to Logfile -- FBLOG_INFO() logging OK -- What is the DIFFERENCE

到目前为止，都是我的日志尝试如下：

#include "logging.h" 
... 
FBLOG_INFO("my function name", "and some text"); 

可选调试级别：

我不知道如果我要重写getLogLevel()，因为我很高兴与默认级别，我不知道究竟把它放在哪里，如果我做覆盖它：

FB::Log::LogLevel getLogLevel(){ 
    return FB::Log::LogLevel_Trace; // Now Trace and above is logged. 
} 

日志文件路径：

我也不确定正确的路径来写日志文件在窗口中。我曾尝试：

- outMethods.push_back(std::make_pair(FB::Log::LogMethod_File, "C:/logs/XXXX/yyyy.log")); 
- outMethods.push_back(std::make_pair(FB::Log::LogMethod_File, "C:\logs\XXXX\yyyy.log")); 
- outMethods.push_back(std::make_pair(FB::Log::LogMethod_File, "/logs/XXXX/yyyy.log")); 
etc. 

准备脚本错误：

在“PluginConfig.cmake”使Log4cplus后与add_firebreath_library(log4cplus)，我得到了我的prep在Windows脚本一些“未找到”的错误，但脚本似乎成功完成，并且我的插件没有错误地构建，所以我选择了迄今为止忽略这些错误。但是，它们是：

我的环境：

我目前正在建设我在Mac和Windows（山狮和Windows 8）的插件。

我在以下浏览器测试：

1. 的Mac：Safari浏览器Chrome的&。
2. Windows：IE 10和Chrome。

FWIW：My Win开发安装位于Mac VMWare Fusion v5.0 Guest中。

摘要：

请帮我拿Log4cplus在我的插件工作与访问日志文件。

Answer 1

看起来你是在正确的轨道上，但是你错过了一个非常重要的一块 - 你不能写入到C：\日志，因为只有管理员有权这样做。

至于“未找到”的“错误”，这些都不是错误的...只是状态消息。这是构建log4cplus的一部分，它希望看到你的平台支持什么。你可以放心地忽略这些。

如果你看看Tips and Tricks页面上，你会发现一些useful examples。

主要一个我指的是来自from a gist I created some time back;您需要使用add_boost_library（文件系统），但是您可以使用此代码来查找将日志放入其中的有效位置。代码当前会检测日志路径（它将在％AppData％\ LocalLow \ CompanyName \ logs中）这个代码）存在，并且只有写入日志。它还使用时间戳和进程ID来确保插件实例的唯一性。

#include <boost/filesystem.hpp> 
#include "SystemHelpers.h" 
using namespace boost::filesystem; 

/// ... 


void getLoggingMethods(FB::Log::LogMethodList& outMethods) 
{ 
    path appDataPath = FB::System::getLocalAppDataPath("CompanyName"); 

    path logDirPath = appDataPath/"logs"; 
    if (exists(logDirPath) && is_directory(logDirPath)) { 
     std::stringstream ss; 
     time_t seconds = time(NULL); 
     boost::thread::id threadId = boost::this_thread::get_id(); 
     ss << seconds << "_" << threadId << ".log"; 

     path logPath = logDirPath/ss.str(); 

     fprintf(stderr, "logging to %s", logPath.string().c_str()); 
     outMethods.push_back(std::make_pair(FB::Log::LogMethod_File, logPath.string())); 
    } 
#ifndef NDEBUG 
    outMethods.push_back(std::make_pair(FB::Log::LogMethod_Console, std::string())); 
#endif 
}
