GZip+Base64压缩字符串在ios上解压报错问题解决（安卓、PC模拟器正常）

java这边的压缩代码

引入的是java8 jdk自带的gzip压缩（ java.util.zip.GZIPOutputStream）、BASE64Encoder( sun.misc.BASE64Encoder)

java 复制代码

public static String compress(String str) {
        if (str != null && str.length() != 0) {
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            GZIPOutputStream gzip = null;

            try {
                gzip = new GZIPOutputStream(out);
                gzip.write(str.getBytes());
            } catch (IOException e) {
                log.error("字符串压缩异常!", e);
                e.printStackTrace();
            } finally {
                IoUtil.close(gzip);
            }

            return (new BASE64Encoder()).encode(out.toByteArray());
        } else {
            return str;
        }
    }

小程序的解压代码

js 复制代码

	let pakoContent =  uni.base64ToArrayBuffer(content);
	pakoContent = pako.ungzip(pakoContent, { to: 'string' });
	return pakoContent

被压缩字符串

ios报错信息

aotb failed : invalid string length 105

经过测试，java端压缩出的结果长度有106，不是4的整数倍

自行查看没有发现明显问题后询问AI查找可能原因

经过验证，确实sum.misc的base64有问题，更换为java.util下的解决了

修改后的
