我们的应用程序使用ng flow上传文件。当我们尝试上传多个文件时,它会对每个文件进行单独的后端调用。所以,如果我们上传100个文件,就会有100个后端服务调用。有没有一种方法可以将数组或文件列表发送到控制器?
下面是代码段:
<div data-flow-object="testModel.documentsFlowObject"
data-flow-files-submitted="testModel.validateAndUpload($files, $event, $flow)"
data-flow-file-success="testModel.documentUploadSuccess($file, $message, $flow)"
data-flow-file-error="testModel.documentUploadError($file, $message, $flow)"
data-flow-init>
function validateAndUpload(files,$event,flow)
{
checkAllFiles(files); // Few validations
for(var file in files)
{
// Flag is set based on validation
var fileName = formatFileName(files[file].name);
if(checkFileNames(fileName)===false)
{
testModel.uploadFlag=false;
break;
}
else
{
setDocumentUploadPath();
testModel.uploadFlag = true;
}
}
if(testModel.uploadFlag===false )
{
$event.preventDefault();
resetDocumentsUpload(files, $event, flow);
}
else
{
LoadingModalService.open();
flow.upload();
}
}
mvc控制器:
@RequestMapping(value = "/documents/{id}", method = POST)
public ResponseEntity<?> uploadDocument(@PathVariable String id, @RequestParam("docIds") List<String> docIds, @RequestParam("file") MultipartFile file) {
有没有办法通过ng流获取请求中的list或multipartfile[]?
