filters

通过配置filters属性,用户可以过滤掉一些不需要捕获的错误,例如:

fundebug.init(
{
    apikey: "API-KEY",
    filters: [
    {
        message: /Cannot read property/
    },
    {
        req:
        {
            method: /^POST$/
        }
    }]
});
配置规则

filters属性有以下特点:

  • 它是一个数组,数组中的元素为过滤规则,当错误符合数组中任意一条过滤规则时,则会被过滤
  • 过滤规则是JavaScript对象,该对象的Key为错误的属性名,Value为正则表达式(唯一的特例是"inexistence");
  • 当错误的属性匹配对应正则表达式时,则会被过滤;
  • 当过滤规则的属性值为"inexistence"时,则会过滤某个属性不存在的错误;
错误事件示例:

测试Fundebug时,在微信开发者工具的调试器中,可以在Network中看到发送到https://wegame.fundebug.net/event/的网络请求,这个请求的body就是我们捕获的错误事件

示例1:过滤ReferenceError的错误
fundebug.init(
{
    apikey: "API-KEY",
    filters: [
    {
        name: /ReferenceError/
    }]
});

示例2:不监控发送到example.com的GET请求错误

fundebug.init(
{
    apikey: "API-KEY",
    filters: [
    {
        req:
        {
            url: /example\.com/,
            method: /^GET$/
        }
    }]
});
示例3:过滤iPhone5上的ReferenceError
fundebug.init(
{
    apikey: "API-KEY",
    filters: [
    {
        name: /^ReferenceError$/,
        systemInfo:
        {
            "model": /^iPhone 5$/,
        }
    }]
});
示例4:配置多条过滤规则
fundebug.init(
{
    apikey: "API-KEY",
    filters: [
    {
        scene: /^1002$/
    },
    {
        message: /TEST 02/,
        scene: /1001/
    }]
});s
