file-upload - 使用 Dart 上传文件到服务器

Question

我正在使用这样的东西进行测试:

_sendFormData(final File file) {
    final HttpRequest httprequest = new HttpRequest();
    final String filename = file.name;

    httprequest.open('POST', "http://localhost:8080/api/file/upload");
    httprequest.on.readyStateChange.add((e) {
      if (httprequest.readyState == 4 && httprequest.status == 200) {
        window.alert("upload complete");
      }
    });

    print("Filename: ${filename}");

    final FormData formData = new FormData();
    formData.append('file', null, filename);
    httprequest.send(formData);
}

是的，我知道我发送的只是文件名，但我如何才能将整个文件发送到服务器？

您应该能够上传文件:

formData.append('file', file);
