我正在尝试使用基于此帖子的Ext JS 6组件从服务器下载文件:download a file via Ext js 4
这是组件代码:
Ext.define('Aft.view.search.FileDownload', {
extend: 'Ext.Component',
alias: 'widget.acw-fileDownload',
autoEl: {
tag: 'iframe',
cls: 'x-hidden',
src: Ext.SSL_SECURE_URL
},
load: function(config){
var e = this.getEl();
e.dom.src = config.url +
(config.params ? '?' + Ext.urlEncode(config.params) : '');
e.dom.onload = function() {
if(e.dom.contentDocument.body.childNodes[0].wholeText == '404') {
console.
Ext.create('Acw.view.commons.notifications.Error', {
html: 'The document you are after can not be found on the server.',
closeAll: true
}).show();
}
}
}
});
doExportData: function(){
this.getView().load({
url: '/aft/faults/download-file'
});
@RequestMapping(value = "/download-file", method = RequestMethod.POST)
public void downloadFilePost(HttpServletResponse response) {
String csvFileName = "searchFaults.csv";
response.setContentType("text/csv");
// creates mock data
String headerKey = "Content-disposition";
String headerValue = String.format("attachment; filename=\"%s\"", csvFileName);
response.setHeader(headerKey, headerValue);
try {
CSVWriter writer = new CSVWriter(response.getWriter(), '\t');
String[] entries = "first#second#third".split("#");
writer.writeNext(entries);
writer.close();
} catch (IOException e) {
// Todo Auto-generated catch block
e.printstacktrace();
}
}
但是,当我打电话时,我得到这样的东西:
[E] Ext.JSON.decode(): You’re trying to decode an invalid JSON String: “first” “second” “third”
Uncaught Error: You’re trying to decode an invalid JSON String: “first” “second” “third”
似乎某些东西到达客户端,但它试图将其解析为JSON.尽管如此,如果我将RequestMethod更改为GET并直接在浏览器中键入URL,我会得到该文件,这使我认为标题是正确的.
有人可以帮我解决这个问题,或者你是否使用不同的方法/组件从服务器下载文件?
解决方法:
doExportData: function(config){
window.location.assign(config.url +
(config.params ? '?' + Ext.urlEncode(config.params) : ''));
});
