window7下karma 报 The header content contains invalid characters BUG

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)
    }
  };
