Question

ASP.NET Web Api无法正确读取流，错误消息为：＆＃34; MIME多部分流的意外结束。 MIME多部分邮件不完整。＆＃34;

这是我的角度上传代码：

    vm.fileUploader = new FileUploader({
    url: 'api/FileAPI/Upload', withCredentials: true, method: 'POST',             
});

vm.fileUploader.onCompleteItem = function (fileItem, response, status, headers) {
    vm.data = response;
};

vm.fileUploader.onBeforeUploadItem = function (item) {
    item.formData = [{ folder: vm.folderName }];
}

这是我读取流的地方以及抛出异常的位置。从api控制器调用此方法，我将form-data作为参数。

    public async Task<IEnumerable<PhotoViewModel>> AddFile(HttpRequestMessage request)
{
    try
    {
        //nothing special in PhotoMultipartFormDataStreamProvider
        var provider = new PhotoMultipartFormDataStreamProvider(this.workingFolder);
        await request.Content.ReadAsMultipartAsync(provider);
        var photos = new List<PhotoViewModel>();
        foreach (var file in provider.FileData)
        {
            var fileInfo = new FileInfo(file.LocalFileName);
            photos.Add(new PhotoViewModel
            {
                Name = fileInfo.Name,
                Size = fileInfo.Length / 1024
            });
        }
        return photos;
    }
    catch(Exception ex)
    {
        throw new Exception("Error uploading file", ex);
    }
}

这是我的请求字符串：

Method: POST, RequestUri: 'http://localhost:49645/api/FileAPI/Upload', Version: 1.1, Content: System.Web.Http.WebHost.HttpControllerHandler+LazyStreamContent, Headers:
{

  Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryxUFnwtUwHSuA4X5Q
}

当我上传没有附加数据的文件时，它工作正常，但是当我添加表单数据时，我得到了这个例外。我试图更改标题，内容类型，但没有运气。我也尝试过从其他问题中读到的东西，但没有使用angular-file-upload。

Answer 1

在onBeforeUploadItem代码中

尝试此操作

vm.fileUploader.onBeforeUploadItem = function (item) {
    item.formData.push({ folder: vm.folderName });
}

angular-file-upload：无法上传带有数据的文件
