Question

我正在使用Java生成一个输入标签，以使用Cloudinary API直接从浏览器上传视频，该API适用于小型视频，但不适用于50 MB视频。

这是生成输入标签的代码：

String html = cloudinary.uploader().imageUploadTag("file", options, htmlOptions);

Map options = ObjectUtils.asMap("resource_type", "video");
    options.put("callback", "/cloudinary_cors.html");
    options.put("eager", eager);
    options.put("eager_async", true);
    options.put("tags", videoTags);
    options.put("use_filename", true);

Map htmlOptions = ObjectUtils.asMap();
    htmlOptions.put("id", "videoInput");
    htmlOptions.put("class", "upload");

这是生成的输入标签的示例：

<input type="file" name="file" 
       data-url="https://api.cloudinary.com/v1_1/rentalwebs/video/upload" 
       data-form-data="{"eager":"c_scale,h_720,w_1280","signature":"xxxfb0c461dxxx",
       "api_key":"xxx1647231xxx","eager_async":true,
       "callback":"/cloudinary_cors.html","tags":"Demo Website,1,Villa Demo 2",
       "use_filename":true,"timestamp":"1548357724"}" 
       data-cloudinary-field="file" class="cloudinary-fileupload upload" id="videoInput">

最后，这些是带有输入标签的附加到页面的.js脚本：

<script th:src="@{/js/jquery.ui.widget.js}" type='text/javascript'></script>
<script th:src="@{/js/load-image.all.min.js}" type='text/javascript'></script>
<script th:src="@{/js/canvas-to-blob.min.js}" type='text/javascript'></script>
<script th:src="@{/js/jquery.iframe-transport.js}" type='text/javascript'></script>
<script th:src="@{/js/jquery.fileupload.js}" type='text/javascript'></script>
<script th:src="@{/js/jquery.fileupload-process.js}" type='text/javascript'></script>
<script th:src="@{/js/jquery.fileupload-image.js}" type='text/javascript'></script>
<script th:src="@{/js/jquery.fileupload-validate.js}" type='text/javascript'></script>
<script th:src="@{/js/jquery.cloudinary.js}" type='text/javascript'></script>


$(document).ready(function() {
              if($.fn.cloudinary_fileupload !== undefined) {
                $("input.cloudinary-fileupload[type=file]").cloudinary_fileupload();
                }
            });

我可能缺少一些找不到的东西。在此问题附带的代码中，还有更多代码用于处理上传过程和结果，但是我想问题是以前发生的。

看起来您只需要向Java中的选项映射添加参数chunk_size。这应该将chunk_size传递给构建了javascript cloudinary_fileupload的blueimp。

我将添加20 MB的块大小，例如options.put("chunk_size", 20000000);

Cloudinary上传器无法处理大型视频
