如何使用dropzone.js上传图像

Question

我想使用// m_handlers is a member of type std::vector<CComPtr<IAssocHandler>> HRESULT FileManager::GetAssocHandlers(const std::wstring& strFileExtension, ASSOC_FILTER filter) { HRESULT hr = S_OK; CComPtr<IEnumAssocHandlers> enumerator; m_handlers.clear(); hr = SHAssocEnumHandlers(strFileExtension.c_str(), filter, &enumerator); if (SUCCEEDED(hr)) { for (CComPtr<IAssocHandler> handler; enumerator->Next(1, &handler, nullptr) == S_OK; handler.Release()) { m_handlers.push_back(handler); } } return hr; } HRESULT FileManager::GetAssociatedPrograms(BSTR bstrFileName, BSTR* bstrRet) { ... hr = GetAssocHandlers(strFileExtension, ASSOC_FILTER_RECOMMENDED); if (SUCCEEDED(hr)) { ... for (auto& handler : m_handlers) { ... if (SUCCEEDED(handler->GetIconLocation(&tmpStr, &resourceIndex))) { // And this is where I get classic full file path to regular // applications like "MS Paint" or this weird path mentioned // above for "Photos" UWP application for example which can't // be used in regular ExtractIcon functions. } } } } 插件上传图片或图片。 但它没有上传图片：

dropzone

我的剧本：

                    <form enctype="multipart/form-data" id="my-awesome-dropzone" class="dropzone dz-clickable" action="http://www.****/Upload.php">
                        <div class="dropzone-previews"></div>
                        <button type="submit" class="btn btn-primary pull-left">Submit</button>
                        <div class="dz-default dz-message"><span>Drop files here to upload</span></div></form>
                    <div>
