How to convert blob to URL in ReactNative

Question

In my ReactNative application, I'm having trouble downloading files

Backend response:

{"_data": {"__collector": {}, "blobId": "E582A159-8E6E-48D2-B245-CA62A7005706", "name": "v1-download-proforma-invoice. json", "offset": 0, "size": 108769, "type": "application/json"}}

I need to download this blob file to the device

Looks like I need a data URL to download the file to my device

How to generate this URL from this response in ReactNative?

I use useMutation hook in react-query to handle this operation

To download data, you can use useQuery and provide the attribute onSuccess:

onSuccess:(blobData)=>{
   const dataUrl = URL.createObjectURL(blobData);
   //现在您拥有了URL，可以根据您的需求下载文件或在浏览器中打开
}
