Linked pull requests. If you're going to use a file as request body, just wrap the path with wrap API. Elements have property filename will be transformed into binary format, otherwise, it turns into utf8 string. What if you want to append a file to form data? But keep in mind when the file is large it's likely to crash your app. Please consider use other strategy see Notice that count argument will not work if the server does not provide response content length.
Upon cancellation, it throws a promise rejection, be sure to catch it. If you have existing code that uses whatwg-fetch the official fetch , it's not necessary to replace them with RNFetchblob. The difference between Official them is official fetch uses whatwg-fetch which wraps XMLHttpRequest polyfill under the hood.
It's a great library for web developers, but does not play very well with RN. Our implementation is simply a wrapper of our fetch and fs APIs, so you can access all the features we provided. See document and examples. If you want to make a file in External Storage becomes visible in Picture, Downloads, or other built-in apps, you will have to use Media Scanner or Download Manager.
When downloading large files on Android it is recommended to use Download Manager , it supports a lot of native features like the progress bar, and notification, also the download task will be handled by OS, and more efficient. When using DownloadManager, fileCache and path properties in config will not take effect, because Android DownloadManager can only store files to external storage, also notice that Download Manager can only support GET method, which means the request body will be ignored.
When download complete, DownloadManager will generate a file path so that you can deal with it. If you need to display a notification upon the file is downloaded to storage as the above or make the downloaded file visible in "Downloads" app. You have to add some options to config. This is a new feature added in 0. File access APIs were made when developing v0.
However, we realized that it's hard to find a great solution to manage cached files, everyone who uses this module may need these APIs for their cases. See File API for more information. In v0. It's handy when processing large files. When calling readStream method, you have to open the stream, and start to read data.
When the file is large, consider using an appropriate bufferSize and interval to reduce the native event dispatching overhead see Performance Tips. The file stream event has a default throttle 10ms and buffer size which preventing it cause too much overhead to main thread, yo can also tweak these values. When using writeStream , the stream object becomes writable, and you can then perform operations like write and close.
Since version 0. The problem with the above code is that the promises from the ofstream. That means the entire promise chain A resolves without waiting for the writes to finish and B any errors caused by them are lost.
That code may seem to work if there are no errors, but those writes are of the type "fire and forget": You start them and then turn away and never know if they really succeeded. The path for iOS and Android is differente. Look at my config.
The file is well downloaded. The thing i can't do is open it with RNFetchBlob. Only to discard mistakes. Are you using the "Download Manager"? Here is a demo of what happens.
I see You are using Download Manager as well. Before I used Download Manager as you can see in my config and it works perfectly. In my opinion, there is some option that you haven't put in your config. Test this options in your code:. I've tried with this image so we can try with the same file ;.
