minio403问题

[water2060]

我能获取到具体的参数
uri:http://localhost:9000/user-profile-picture
x-amz-date:20240412T060645Z
x-amz-signature:545fcd84eac9447574832351c5b0266ad403d18135aa2412eed1dca83c27630a

key:1

但是使用StorageService里面的upload会提示403。
然而上面的参数，我用下面的代码，是可以上传成功的额，不会报403

public static void main(String[] args) throws IOException, InvalidKeyException, NoSuchAlgorithmException, ErrorResponseException, InternalException, InsufficientDataException {
String endpoint = "http://localhost:9000"; // MinIO服务的URL
String accessKey = "minioadmin"; // MinIO访问密钥
String secretKey = "minioadmin"; // MinIO访问密钥的密钥

    // 创建MinioClient对象
    MinioClient minioClient = MinioClient.builder()
            .endpoint(endpoint)
            .credentials(accessKey, secretKey)
            .build();

    // 上传文件
    try {
        String bucketName = "user-profile-picture";
        String objectName = "1";
        File file = new File("D:\\1.png"); // 读取的文件路径 // 要上传的文件内容，这里是示例内容

        // 生成POST Policy
        String policy = generatePostPolicy(bucketName, objectName);

        // 计算签名
        String signature = generateSignature(secretKey, policy);
        
        // 上传文件
        Map<String, String> headers = new HashMap<>();
        headers.put("x-amz-algorithm", "AWS4-HMAC-SHA256");
        headers.put("x-amz-credential", "minioadmin/20240412/us-east-1/s3/aws4_request");
        headers.put("x-amz-date", "20240412T050414Z");
        headers.put("policy", "eyJleHBpcmF0aW9uIjoiMjAyNC0wNC0xMlQwNTowOToxNC4xODZaIiwiY29uZGl0aW9ucyI6W1siZXEiLCIkYnVja2V0IiwidXNlci1wcm9maWxlLXBpY3R1cmUiXSxbImVxIiwiJGtleSIsIjEiXSxbInN0YXJ0cy13aXRoIiwiJENvbnRlbnQtVHlwZSIsImltYWdlLyJdLFsiY29udGVudC1sZW5ndGgtcmFuZ2UiLDAsMTA0ODU3Nl0sWyJlcSIsIiR4LWFtei1hbGdvcml0aG0iLCJBV1M0LUhNQUMtU0hBMjU2Il0sWyJlcSIsIiR4LWFtei1jcmVkZW50aWFsIiwibWluaW9hZG1pbi8yMDI0MDQxMi91cy1lYXN0LTEvczMvYXdzNF9yZXF1ZXN0Il0sWyJlcSIsIiR4LWFtei1kYXRlIiwiMjAyNDA0MTJUMDUwNDE0WiJdXX0=");
        headers.put("x-amz-signature", "8a27fb50dd530860bb8d188f7d8b9a8c015c623c8360bebece073e2f9dfa0420");
        headers.put("key", "1");
        for (Map.Entry<String, String> entry : headers.entrySet()) {
            System.out.println(entry.getKey() + ": " + entry.getValue());
        }

        minioClient.putObject(io.minio.PutObjectArgs.builder()
                .bucket(bucketName)
                .object(objectName)
                .headers(headers)
                .contentType("application/octet-stream")
                .stream(new FileInputStream(file), file.length(), -1)
                .build());

        System.out.println("File uploaded successfully.");
    } catch (MinioException e) {
        e.printStackTrace();
    }
}

报403的提示如下：
code: 91, reason: Failed to retrieve the resource because the HTTP response status code is: 403

I just updated turms-plugin-minio days ago. You can download and use the latest turms-plugin-minio to have a try first.

And the clients should always pass the non-null mediaType value when calling uplodateXXX methods in storageService so that it can pass the Content-Type header, or you will get the 403 error.

If you have followed the steps mentioned above and still encounter 403, it is suggested you can set a break point on the HTTP response so that you can view the HTTP response body as a string, and the body will tell you the exact reason why the request fails.

我明白了。kotlin里面需要

这样写就ok了
