使用post方法反应本机rn-fetch-blob下载

Question

我需要下载一个文件(.pdf)，这是来自flask rest API的代码

return send_file(file_location, as_attachment=True)

我试着使用RNFetchBlob

RNFetchBlob
        .config({
            addAndroidDownloads: {
                useDownloadManager: true, // <-- this is the only thing required
                // Optional, override notification setting (default to true)
                notification: false,
                // Optional, but recommended since android DownloadManager will fail when
                // the url does not contains a file extension, by default the mime type will be text/plain
                mime: 'application/pdf',
                description: 'File downloaded by download manager.',
            },
          })
          .fetch('POST', 'http://192.168.0.199:8000/v1/quote/view', data)
          .then((res)=>console.log('The file saved to ', res.path()))
          .catch((err)=>console.log(err));

但是，即使我在flask中提到POST方法，它也是作为GET方法接收的

192.168.0.186 - - [11/Aug/2021 19:05:31] "GET /v1/quote/view HTTP/1.1" 405 -

我做错了什么？

感谢@Xhirazi，

fetch(方法、URL、headers、body)的顺序应该是这样的，修复了这个问题
