node 处理 response和java接口的返回

var body = ‘’;
response.setEncoding(‘utf8’);

    response.on('data', function (chunk) {
        body += chunk;
    });
    response.on('end', function(){
        callback({'httpcode':response.statusCode, 'code':response.statusCode , 'message':statusText(response.statusCode) , 'data':JSON.parse(body)});
    });
