Object Storage Service：Java異常處理

異常處理樣本

以下代碼用於展示異常處理：

try {
    // OSS操作，例如上傳檔案
    ossClient.putObject(...);
} catch (OSSException oe) {
    System.out.println("Caught an OSSException, which means your request made it to OSS, "
            + "but was rejected with an error response for some reason.");
    System.out.println("Error Message: " + oe.getErrorMessage());
    System.out.println("Error Code:       " + oe.getErrorCode());
    System.out.println("Request ID:      " + oe.getRequestId());
    System.out.println("Host ID:           " + oe.getHostId());
} catch (ClientException ce) {
    System.out.println("Caught an ClientException, which means the client encountered "
            + "a serious internal problem while trying to communicate with OSS, "
            + "such as not being able to access the network.");
    System.out.println("Error Message: " + ce.getMessage());
} finally {
    if (ossClient != null) {
        ossClient.shutdown();
    }
}
            

ClientException

ClientException指用戶端嘗試向OSS發送請求以及資料轉送時遇到的異常。例如，當發送請求時網路連接不可用，則會拋出ClientException。當上傳檔案時發生IO異常，也會拋出ClientException。

OSSException

OSSException指伺服器端異常，即對伺服器錯誤資訊的解析。OSSException包含OSS返回的錯誤碼和錯誤資訊，便於定位問題，並做出適當的處理。

OSSException通常包含以下錯誤資訊：
