golang获取调用者的方法名及所在源码行数

代码如下

参数：skip是要提升的堆栈帧数，0-当前函数，1-上一层函数，....

返回值：

pc是uintptr这个返回的是函数指针

file是函数所在文件名目录

line所在行号

ok 是否可以获取到信息

  pc0, file0, line0, ok0 := runtime.Caller(0)
  logs.Error(" runtime.Caller(0) pc0:",pc0)
  logs.Error(" runtime.Caller(0) file0:",file0)
  logs.Error(" runtime.Caller(0) line0:",line0)
  logs.Error(" runtime.Caller(0) ok0:",ok0)
  f0 := runtime.FuncForPC(pc0)
  logs.Error(" runtime.FuncForPC(pc0):",f0.Name())
  pc1, file1, line1, ok1 := runtime.Caller(1)
  logs.Error(" runtime.Caller(1) pc1:",pc1)
  logs.Error(" runtime.Caller(1) file1:",file1)
  logs.Error(" runtime.Caller(1) line1:",line1)
  logs.Error(" runtime.Caller(1) ok1:",ok1)
  f1 := runtime.FuncForPC(pc1)
  logs.Error(" runtime.FuncForPC(pc1):",f1.Name())
  pc2, file2, line2, ok2 := runtime.Caller(2)
  logs.Error(" runtime.Caller(2) pc2:",pc2)
  logs.Error(" runtime.Caller(2) file2:",file2)
  logs.Error(" runtime.Caller(2) line2:",line2)
  logs.Error(" runtime.Caller(2) ok2:",ok2)
  f2 := runtime.FuncForPC(pc2)
  logs.Error(" runtime.FuncForPC(pc2):",f2.Name())

输入结果
