How to read the network picture file stream and display it by Weex

due to business needs, I want to request (stream) through the network in the vue code of native weex to read a picture and display it on the page. I am listening to the return of the request, and the picture has been returned normally. Please tell me, how can I read the stream and display it in the interface?

<image :src="picSr" resize="contain"></image>


 stream.fetch({
    method: "GET",
    url: url,
    type: "arraybuffer"
} (resp) => {
//(blob)?
    this.picSr = resp.data //new Filereader, new Blob
},
(resp)=>{
    //progressCallback
})

finally let the server return in the form of base64 string to solve
