Question

我正在尝试将 pptx 文件发送到此 link 处的 django 服务器

这是原始 django 应用程序中的 html 表单：

<form method="post" enctype="multipart/form-data" action="find_file_type">
{% csrf_token %}
<div>
    <label class = "custom-file-upload" >
        Choose file
        <input name = "filePath" type="file" accept = ".pdf , application/vnd.ms-powerpoint , application/vnd.openxmlformats-officedocument.presentationml.presentation" id="file">
    </label>
    <input type="submit" value="Make it dark" id= "submit">
</div>

</form>

我无法将文件发送到此服务器，也不知道出了什么问题。这是我使用 dio 包尝试过的：

void sendRequest() async{
    FormData formData = new FormData.fromMap({
      "file": await MultipartFile.fromFile(file.path,filename: filename)});
    response = await dio.post("https://nitemode.herokuapp.com/find_file_type", data: formData);
    print(response);
    if (response.statusCode == 200 || response.statusCode == 201) {
      print('Uploaded!');
    }
    print("Process complete");

  }
}

这是我得到的输出：

我不知道我做错了什么。 django 应用程序在文件上传后发送下载，这就是我收到此错误的原因吗？由于 django 应用程序不发送 200 或 203 响应，但响应如下：

response = HttpResponse(myfile, content_type='application/[vnd.openxmlformats-officedocument.presentationml.presentation]')
    response['Content-Disposition'] = 'attachment; filename='  + 'DarkFile.pptx'

请帮帮我，我不知道我做错了什么。我也阅读了 dio 的文档，但不知道我做错了什么我也试过 dio 中的 download() 函数，但没有下载文件。我还一起完成了一个 post() 和一个 donwload() 函数，但也没有任何作用。

如何将文件从颤振发送到 django 应用程序？
