var template = encodeURIComponent(JSON.stringify(templateJosn))
var datasource = encodeURIComponent(JSON.stringify(datasourceJson))
var url = "http://127.0.0.1:9523/preview"
//var url = "http://127.0.0.1:9523/print" //直接打印地址
//var url = "http://127.0.0.1:9523/printDialog" //调用打印设置打印地址
var httpRequest = new XMLHttpRequest();

        console.info(httpRequest.responseText);
        var data = JSON.parse(httpRequest.responseText);
        if(data.code=='0'){
