文件上传返回200但文件未上传（表示春季）

Question

我正在尝试将文件从我的本地uploads文件夹上传到外部网络服务器(Java Spring)，但我似乎无法让它工作。我收到200 Ok状态返回但是当我检查时，文件尚未上传。

以下是我的参考代码：

var form = new FormData();

form.append('my_field', 'my value');
form.append('my_buffer', new Buffer(10));
form.append('my_logo', request('http://localhost:8080/' + req.files.file.path));

request({
    url: someDomain + '/proj/new/deliveryAttachment',
    method: "POST",
    headers: {
        'Accept' : 'application/json, text/plain, */*',
        'Content-Type': 'multipart/form-data'
    },
    jar: getJar(),
    qs: {
        pid: req.query.id
    },
    formData: {
        deliveryAttachment: form
    }
}, function (error, response, body) {       
    res.send(body);
});

这是Java Spring控制器：

@RequestMapping(value = "proj/new/deliveryAttachment", method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE, produces = MediaType.TEXT_PLAIN_VALUE)
public String insertDeliveryAttachment(@RequestParam("pid") long pid,
        @RequestParam("deliveryAttachment") MultipartFile file) {
    try {
        DeliveryAttachment a = new DeliveryAttachment(file.getOriginalFilename(), pid);
        ps.insertDeliveryAttachment(a, file.getBytes());
        return String.valueOf(a.id);
    } catch (IOException e) {
        return "-1";
    }
}

任何帮助将不胜感激！

修改

我已经屏蔽了控制台日志，它似乎只能通过中间件API传递到它从uploads文件夹中获取文件的部分。它不会进入request.post。

要检索文件，请按以下步骤处理：

@RequestMapping(value = "proj/new/deliveryAttachment", method =RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE, produces = MediaType.TEXT_PLAIN_VALUE)
public String insertDeliveryAttachment(@RequestParam("pid") long pid,
    @RequestPart("deliveryAttachment") MultipartFile file) // This is the key annotation to use
{
    //Your code here 
}
