打印堆栈:printStack god.printstack()

得到堆栈String:getStack

----------------php,

debug_print_backtrace(),加入error line的前面行上...

保存stack到文件：print_r(debug_backtrace());

C:\phpdeskc9>D:\wamp\php\php.exe E:\DedeCMS-V5.7-UTF8-SP1-Full\uploads\del_some

_dir.php E:\OfflineExplorerPortable\Download budejie,xiaohua

#0 c() called at [E:\DedeCMS-V5.7-UTF8-SP1-Full\uploads\del_some_dir.php:31]

#1 b() called at [E:\DedeCMS-V5.7-UTF8-SP1-Full\uploads\del_some_dir.php:27]

#2 a() called at [E:\DedeCMS-V5.7-UTF8-SP1-Full\uploads\del_some_dir.php:38]

Fatal error: Call to undefined function d() in E:\DedeCMS-V5.7-UTF8-SP1-Full\upl

oads\del_some_dir.php on line 35

debug_backtrace() 函数生成一个 backtrace。[1]

该函数返回一个关联数组

------------java

e.printStackTrace()

保存stack到文件,方法1

StackTraceElement [] messages=ex.getStackTrace();

int length=messages.length;

for(int i=0;i<length;i++){

System.out.println("ClassName:"+messages[i].getClassName());

System.out.println("getFileName:"+messages[i].getFileName());

System.out.println("getLineNumber:"+messages[i].getLineNumber());

System.out.println("getMethodName:"+messages[i].getMethodName());

System.out.println("toString:"+messages[i].toString());

}

}

保存stack到文件,方法2

public String getTrace(Throwable t) {

StringWriter stringWriter= new StringWriter();

PrintWriter writer= new PrintWriter(stringWriter);

t.printStackTrace(writer);

StringBuffer buffer= stringWriter.getBuffer();

return buffer.toString();

}

------------python

info = traceback.format_exc()

print info
