我使用AngularJS與使用$ resource的REST風格的Web服務(使用spring引導運行)進行通信。我想上傳一些文件和相同的多POST請求內發送表單字段,但我得到以下錯誤:

"Unsupported Media Type" exception: "org.springframework.web.HttpMediaTypeNotSupportedException" message: "Content type 'application/xml' not supported" path: "/study/upload" status: 415

這裏是我的看法形式:

<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> 

這裏是視圖控制器:

$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() { 

'嚴格使用'; ('GalleryService',GalleryService);或者,您可以使用以下功能:

功能GalleryService($資源,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 }} 


}); 

}

})();

這裏是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"; 
}

我看不出有什麼

GalleryService.upload 

是幹什麼的,但看起來你並沒有真正發送表單到服務器,但只有一些領域。在這種情況下,

enctype="multipart/form-data" 

將不會被使用,這可以解釋您收到的錯誤。

看看瀏覽器中的開發人員工具,哪個請求實際上發送到您的服務器以及它正在使用哪種內容類型。
