有没有朋友支个招，为什么 MInIo文件上传下载生成的签名地址不能使用，总是报签名不匹配。

Question

以下是生成上传下载签名方法：

void contextLoads() {
        String SIGN = "";
        Map<String, String> reqParams = new HashMap<String, String>();
        reqParams.put("response-content-type", "application/json");
         SIGN = minIoUtil.getMinIoClient().getPresignedObjectUrl(
                GetPresignedObjectUrlArgs.builder()
                        .method(Method.GET)
                        .bucket("images")
                        .object("1.jpg")
                        .expiry(1, TimeUnit.DAYS)
                        .build()
        );
        log.info("下载地址：" +SIGN);
        SIGN = minIoUtil.getMinIoClient().getPresignedObjectUrl(
                GetPresignedObjectUrlArgs.builder()
                        .method(Method.PUT)
                        .bucket("images")
                        .object("1.jpg")
                        .expiry(1, TimeUnit.DAYS)
                        .extraQueryParams(reqParams)
                        .build()
        );
        log.info("上传地址：" +SIGN);
    }

以下是官网生成上传下载签名方法

// Get presigned URL string to upload 'my-objectname' in 'my-bucketname' 
// with response-content-type as application/json and life time as one day.
Map<String, String> reqParams = new HashMap<String, String>();
reqParams.put("response-content-type", "application/json");

String url =
    minioClient.getPresignedObjectUrl(
        GetPresignedObjectUrlArgs.builder()
            .method(Method.PUT)
            .bucket("my-bucketname")
            .object("my-objectname")
            .expiry(1, TimeUnit.DAYS)
            .extraQueryParams(reqParams)
            .build());
System.out.println(url);

// Get presigned URL string to download 'my-objectname' in 'my-bucketname' and its life time
// is 2 hours.
String url =
    minioClient.getPresignedObjectUrl(
        GetPresignedObjectUrlArgs.builder()
            .method(Method.GET)
            .bucket("my-bucketname")
            .object("my-objectname")
            .expiry(2, TimeUnit.HOURS)
            .build());
System.out.println(url);
