如题，原生包下载热更文件时失败，但是在浏览器中是能访问的，用curl也能下载成功，怀疑是证书的问题，但是不知道底层是用什么方法实现https下载，使用cacert.pem证书验证。

原生实现下载的代码是这部分：
-------------async.js-----------
...

function downloadSync(url, bin, onprog) {
    return new Promise(function (resolve, reject) {
        var f = new conch_File(url);
        var fr = new conch_FileReader();
        fr.setIgnoreError(true);
        fr.onload = () => {
            console.log('download end');
            resolve(fr.result);
        };
        fr.onerror = (e) => { console.log('onerror ' + e); 
            //if (reject)
            //    reject(e); 
            resolve(null);
        };
        fr.onprogress = onprog;
        if (bin)
            fr.readAsArrayBuffer(f);
        else
            fr.readAsText(f);
    });
}

...

conch_File 在runtimeInit.js定义

window = this;
window.conch_File=File;
window.conch_FileReader = FileReader;
