使用FileReader和mammoth库处理安卓docx文件预览问题？

Question

读取安卓本地docx 文件 转成ArrayBuffer，生成一堆数字（大佬看我转的对吗？）

export const readFile = (path) => {
            return new Promise((reslove, reject) => {
                plus.io.resolveLocalFileSystemURL(path,(entry)=> {
                    entry.file((file) => {
                        const fileReader = new plus.io.FileReader();
                        fileReader.onloadend = (e) => { 
                            let s = e.target.result  
                            s = s.replace(/^data:[^;]+;base64,/, '')  
                            s = uni.base64ToArrayBuffer(s)  
                            const int8array = new Int8Array(s);
                            reslove(int8array)  
                        }
                        fileReader.readAsText(file);
                        fileReader.onerror = (error)=> {
                            reject(error)
                        }
                    })
                },(error) => {
                    reject(error)
                })
            })
        }

利用mammoth将res1 arrayBuffer 传入 转备转成html用来预览docx文件

mammoth.convertToHtml({arrayBuffer: res1}, options).then(function(result){
                       const html = result.value
                       console.log(html)
                     }).catch(function(err){
                       console.log(err)
                     })

报错：Can't read the data of 'the loaded zip file'. Is it in a supported JavaScript type (String, Blob, ArrayBuffer, etc) ?
