使用角厂服务和$资源将分段上传到Spring Rest
我使用AngularJS与REST风格的Web服务(使用spring启动)进行通信,使用$ resource。 我试图上传一些文件并发送一个相同的多部分发布请求中的表单域,但我收到以下错误:
“不支持的媒体类型”异常:“org.springframework.web.HttpMediaTypeNotSupportedException”消息:“不支持内容类型'application / xml'路径:”/ study / upload“状态:415
这里是我的观点形式:
<form method="post" enctype="multipart/form-data" ng-submit="submit()">
<table>
<tr><td>File to upload:</td><td><input type="file" name="file" ng-model="form.file"/></td></tr>
<tr><td>Name:</td><td><input type="text" name="name" ng-model="form.name"/></td></tr>
<tr><td></td><td><input type="submit" value="Upload" /></td></tr>
</table>
</form>
这里是视图控制器:
$scope.submit=function(){
GalleryService.upload({file: $scope.form.file, name: $scope.form.name}, function(data) {
console.log("Success ... " + status);
}, function(error) {
console.log(error);
});
}
gallery.service:
(function() {
'严格使用';
angular .module('ekellsApp').factory('GalleryService',GalleryService);
函数GalleryService($ resource,restApi){
return $resource(restApi.url + '/study/:action', {},{
save: {method: 'POST', params: {action: 'save'}},
getAll: {method: 'GET', params: {action: 'getAll'},isArray:true},
upload: {method: 'POST', params: {action: 'upload'}, transformRequest: angular.identity,headers: { 'Content-Type': undefined }}
});
}
})();
这里是REST控制器:
@RequestMapping(value = "/upload",method = RequestMethod.POST,headers = "content-type=multipart/*")
public String handleFileUpload(@RequestParam("name") String name,
@RequestParam("file") MultipartFile file,
RedirectAttributes redirectAttributes) {
if (name.contains("/")) {
redirectAttributes.addFlashAttribute("message", "Folder separators not allowed");
return "redirect:upload";
}
if (name.contains("/")) {
redirectAttributes.addFlashAttribute("message", "Relative pathnames not allowed");
return "redirect:upload";
}
if (!file.isEmpty()) {
try {
BufferedOutputStream stream = new BufferedOutputStream(
new FileOutputStream(new File("user/bouhuila/" + name)));
FileCopyUtils.copy(file.getInputStream(), stream);
stream.close();
redirectAttributes.addFlashAttribute("message",
"You successfully uploaded " + name + "!");
}
catch (Exception e) {
redirectAttributes.addFlashAttribute("message",
"You failed to upload " + name + " => " + e.getMessage());
}
}
else {
redirectAttributes.addFlashAttribute("message",
"You failed to upload " + name + " because the file was empty");
}
return "redirect:upload";
}
我看不到什么
GalleryService.upload
正在做,但看起来你并没有真正发送表单到服务器,但只有一些字段。 在这种情况下
enctype="multipart/form-data"
将不会被使用,这可以解释你得到的错误。
查看浏览器中的开发人员工具,该请求实际上已发送到服务器以及它正在使用哪种内容类型..
