Terakhir diperbarui: 2024-02-04 15:40:24

Overview

This document provides an overview of APIs and SDK code samples for hash calculation.
API
Description
Uses a sync GET request to perform hash calculation and return a calculated hash value in real time.
Submits a hash calculation job through a POST request. You can submit a job to perform hash calculation and asynchronously return a calculated hash value.
Queries the result of a specified hash calculation job.

Sync Request for Hash Calculation

Feature description

This API uses a sync GET request to perform hash calculation and return a calculated hash value in real time.

Method prototype

public Guzzle\\Service\\Resource\\Model FileJobs4Hash(array $args = array());

Sample request

<?php

require dirname(__FILE__, 2) . '/vendor/autoload.php';

$secretId = "SECRETID"; //Replace it with the actual `SecretId`, which can be viewed and managed in the CAM console at https://console.tencentcloud.com/cam/capi
$secretKey = "SECRETKEY"; //Replace it with the actual `SecretKey`, which can be viewed and managed in the CAM console at https://console.tencentcloud.com/cam/capi
$region = "ap-beijing"; //Replace it with the actual `region`, which can be viewed in the console at https://console.tencentcloud.com/cos5/bucket.
$cosClient = new Qcloud\\Cos\\Client(
    array(
        'region' => $region,
        'schema' => 'https', // Protocol, which is `http` by default
        'credentials'=> array(
            'secretId'  => $secretId ,
            'secretKey' => $secretKey)));
try {
    // https://www.tencentcloud.com/document/product/436/53990: Sync Request for Hash Calculation
    $result = $cosClient->FileJobs4Hash(array(
        'Bucket' => 'examplebucket-1250000000', // Bucket name in the format of `BucketName-Appid`, which can be viewed in the COS console at https://console.tencentcloud.com/cos5/bucket.
        'Key' => 'for-test.mp4', // File in the bucket
        'Type' => 'md5', // Supported hash algorithm. Valid values: `md5`, `sha1`, `sha256`
//        'AddToHeader' => 'true', // Whether to automatically add the calculated hash value to the custom header in the file. Format: x-cos-meta-md5/sha1/sha256. Valid values: `true`, `false`. If this parameter is left empty, it is `false` by default.
    ));
    // Request succeeded
    print_r($result);
} catch (\\Exception $e) {
    // Request failed
    echo($e);
    /**
     * Possible exceptions
     * 1. Error Message: file processing is not active yet, please apply for file processing service first
     *    Solution: Activate the file processing service.
     */
