贴代码：

function getData(url, callback) {
    stream.sendHttp({
        method: ‘GET’,
        url: url
    }, function (ret) {
        var retdata = JSON.parse(ret);
    });
}

retdata为json object，其中里面有一个属性 Time 的值为 null ，怎么判断这个属性值是不是为 null ？
用了 retdata.Time == null 一直是 false（如果是用浏览器调试的话是 true，但是上了Android之后是 false），然后打印出来 retdata.Time 是 [object object]

{"Res":'',"Ret":{"Time":null,"Date":20160909}}
其中Ret里的Time的值为null

你先打印ret,看看是什么内容.

btw: sendhttp接口将会启用,改用stream.fetch

恩，用stream.fetch发现一个新问题：
stream.fetch({
method: ‘GET’,
url: url
}, function (ret) {
// modal.alert ( "ret = " + ret +" --- " + ret.Ret );
});

在浏览器上调试，打印出是 “ret = [object Object] --- [object Object]”;
在Android上测试，打印出是“ret = [object Object] --- undefined”;
经过抓包看两者请求的返回结果都是 {"Res":'',"Ret":{"Time":null,"Date":20160909}}

fetch的数据结构与sendhttp不同,具体请看一下 http://alibaba.github.io/weex/doc/modules/stream.html,
是在data字段中,而不是在第一级结构里,h5的实现有点问题,会进行修改.
