javascript - 在 react-native 中下载 "Content-Disposition": "attachment; filename=example.mp3"

Question

我试图下载一个 mp3 文件，它的名称在 URL 中指定。

https://aaaa&user=shanto3@gmail.com&pass=aaaa&device_id=0ef2c8496369ade1&input_text=Fine&lang=fr&output_file=151.20200706103512.mp3&info=tts_mp3

我想下载151.20200706103512.mp3文件。

            RNFetchBlob
            .config({
                fileCache: true,
                appendExt: 'mp3'
            })
            .fetch('GET', url, {
                'Content-Type': 'multipart/form-data'
            })
            .then((res) => {
                console.log(res);
                let path = 'file://' + res.path()
                console.log(path);
            })
            .catch((errorMessage, statusCode) => {
                // error handling
            })

作为回应，我得到了以下内容，其中包括 "Content-Description":"File Transfer", "Content-Disposition":"attachment; filename=151.20200706103512.mp3"。这里显示我的文件保存在 data 指定的目录中，但我在那里找不到任何文件。
