sourcemap-stack v1.0.2
sourcemap-stack
参数定义
| 参数属性 | 说明 |
|---|---|
| mapUrl | sourcemap 地址链接，如果不填，表示sourcemap地址跟实际js路径一样 |
| mapName | 参考webpack的地址格式，比如：name.hash.js.map |
| mapEncrypt | 如果map文件放到跟js同目录下，一起发布到cdn上，处于安全考虑，可以使用对称性加密map文件,加密包使用encrypte,如果没有加密，这项不填 |
| desc | js error 的堆栈信息 |
API
getStackByError
根据错误的stack error信息，提取出调动的堆栈关系
Input:
TypeError: console.logs is not a function

]getMapPath
根据map参数的配置，获取sourcemap地址

]getRealStack
解析真正的调用关系
调用demo
// 获取请求内容
let params = this.ctx.request.body
// 获取调用堆栈
let stacks = sourcemapStack.getStackByError(params.desc)
// 增加map地址
sourcemapStack.getMapPath(stacks, params)
// 获取真实调用地址
stacks = yield sourcemapStack.getRealStack(stacks)
