打开你的依赖node_modules\karma\node_modules\connect\lib\patch.js

将里面的setHeader方法改成下面这样,干掉序列化日期时出现的中文

res.setHeader = function(field, val){    var key = field.toLowerCase()      , prev;    // special-case Set-Cookie    if (key === 'set-cookie') {      // detect code doing getHeader -> setHeader      if (Array.isArray(val) && val.length > 1) {        prev = [].concat(this.getHeader(field) || []);        val = unique(prev, val);      }      return this.appendHeader(field, val);    }    // charset    if ('content-type' == key && this.charset) {      val = utils.setCharset(val, this.charset, true);    }    try{        if(typeof  val === 'string'){          val =  val.replace(/中国标准时间/,'')        }        return setHeader.call(this, field, val);    }catch(e){      console.log(e, val,field)    }  };
