简介

本文档提供关于日志管理的 API 概览以及 C SDK 示例代码。

设置日志管理

功能说明

PUT Bucket logging 用于为源存储桶开启日志记录，将源存储桶的访问日志保存到指定的目标存储桶中。

方法原型

cos_status_t *cos_put_bucket_logging(const cos_request_options_t *options,
                                      const cos_string_t *bucket,
                                      cos_logging_params_t *logging_params,
                                      cos_table_t **resp_headers);

请求示例

cos_pool_t *pool = NULL;
int is_cname = 0; 
cos_status_t *status = NULL;
cos_request_options_t *options = NULL;
cos_logging_params_t  *params = NULL;
cos_logging_params_t  *result = NULL;
cos_table_t *resp_headers = NULL;
cos_string_t bucket;

//创建内存池
cos_pool_create(&pool, NULL);

//初始化请求选项
options = cos_request_options_create(pool);
options->config = cos_config_create(options->pool); 
cos_str_set(&options->config->endpoint, TEST_COS_ENDPOINT);
cos_str_set(&options->config->access_key_id, TEST_ACCESS_KEY_ID);
cos_str_set(&options->config->access_key_secret, TEST_ACCESS_KEY_SECRET);
cos_str_set(&options->config->appid, TEST_APPID);
options->config->is_cname = is_cname;
options->ctl = cos_http_controller_create(options->pool, 0);
cos_str_set(&bucket, TEST_BUCKET_NAME);

//创建 logging 参数
params = cos_create_logging_params(options->pool);
cos_str_set(&params->target_bucket, TEST_BUCKET_NAME);
cos_str_set(&params->target_prefix, "logging/");

//设置日志管理
status = cos_put_bucket_logging(options, &bucket, params, &resp_headers);
log_status(status);

//销毁内存池
cos_pool_destroy(pool);

查询日志管理

功能说明

GET Bucket logging 用于查询指定存储桶的日志配置信息。

方法原型

cos_status_t *cos_get_bucket_logging(const cos_request_options_t *options,  
                                      const cos_string_t *bucket,    
                                      cos_logging_params_t *logging_params,
                                      cos_table_t **resp_headers);

请求示例

cos_pool_t *pool = NULL;
int is_cname = 0; 
cos_status_t *status = NULL;
cos_request_options_t *options = NULL;
cos_logging_params_t  *params = NULL;
cos_logging_params_t  *result = NULL;
cos_table_t *resp_headers = NULL;
cos_string_t bucket;

//创建内存池
cos_pool_create(&pool, NULL);

//初始化请求选项
options = cos_request_options_create(pool);
options->config = cos_config_create(options->pool); 
cos_str_set(&options->config->endpoint, TEST_COS_ENDPOINT);
cos_str_set(&options->config->access_key_id, TEST_ACCESS_KEY_ID);
cos_str_set(&options->config->access_key_secret, TEST_ACCESS_KEY_SECRET);
cos_str_set(&options->config->appid, TEST_APPID);
options->config->is_cname = is_cname;
options->ctl = cos_http_controller_create(options->pool, 0);
cos_str_set(&bucket, TEST_BUCKET_NAME);

// 查询日志配置
result = cos_create_logging_params(options->pool);
status = cos_get_bucket_logging(options, &bucket, result, &resp_headers);
log_status(status);

if (!cos_status_is_ok(status)) {
    cos_pool_destroy(pool);
    return;
}    

//查看结果
char *line = NULL;
line = apr_psprintf(options->pool, "%.*s\n", result->target_bucket.len, result->target_bucket.data);
printf("target bucket: %s", line);
line = apr_psprintf(options->pool, "%.*s\n", result->target_prefix.len, result->target_prefix.data);
printf("target prefix: %s", line);

//销毁内存池
cos_pool_destroy(pool);
