从内存中上传数据

以下代码用于从内存中上传数据：

#include "oss_api.h"
#include "aos_http_io.h"
const char *endpoint = "<yourEndpoint>";
const char *access_key_id = "<yourAccessKeyId>";
const char *access_key_secret = "<yourAccessKeySecret>";

const char *object_name = "<yourObjectName>";
const char *object_content = "More than just cloud.";
void init_options(oss_request_options_t *options)

    /* 用于内存管理的内存池（pool），等价于apr_pool_t。其实现代码在apr库中。*/

上传本地文件

以下代码用于上传本地文件：

#include "oss_api.h"
#include "aos_http_io.h"
const char *endpoint = "<yourEndpoint>";
const char *access_key_id = "<yourAccessKeyId>";
const char *access_key_secret = "<yourAccessKeySecret>";
const char *bucket_name = "<yourBucketName>";
const char *object_name = "<yourObjectName>";
const char *local_filename = "<yourLocalFilename>";
void init_options(oss_request_options_t *options)
{
    options->config = oss_config_create(options->pool);
    /* 用char*类型的字符串初始化aos_string_t类型。*/
    aos_str_set(&options->config->endpoint, endpoint);
    aos_str_set(&options->config->access_key_id, access_key_id);
    aos_str_set(&options->config->access_key_secret, access_key_secret);
    /* 是否使用了CNAME。0表示不使用。*/
    options->config->is_cname = 0;
    /* 设置网络相关参数，比如超时时间等。*/
    options->ctl = aos_http_controller_create(options->pool, 0);
}
int main(int argc, char *argv[])
{
    /* 在程序入口调用aos_http_io_initialize方法来初始化网络、内存等全局资源。*/
    if (aos_http_io_initialize(NULL, 0) != AOSE_OK) {
        exit(1);
    }
    /* 用于内存管理的内存池（pool），等价于apr_pool_t。其实现代码在apr库中。*/
    aos_pool_t *pool;
    /* 重新创建一个内存池，第二个参数是NULL，表示没有继承其它内存池。*/
    aos_pool_create(&pool, NULL);

    oss_request_options_t *oss_client_options;
    /* 在内存池中分配内存给options。*/
    oss_client_options = oss_request_options_create(pool);
    /* 初始化Client的选项oss_client_options。*/
    init_options(oss_client_options);
    /* 初始化参数。*/
    aos_string_t bucket;
    aos_string_t object;
    aos_string_t file;
    aos_table_t *headers = NULL;
    aos_table_t *resp_headers = NULL; 
    aos_status_t *resp_status = NULL; 
    aos_str_set(&bucket, bucket_name);
    aos_str_set(&object, object_name);
    aos_str_set(&file, local_filename);
    /* 上传文件。*/
    resp_status = oss_put_object_from_file(oss_client_options, &bucket, &object, &file, headers, &resp_headers);
    /* 判断上传是否成功。*/
    if (aos_status_is_ok(resp_status)) {
        printf("put object from file succeeded\n");
    } else {
        printf("put object from file failed\n");
    }
    /* 释放内存池，相当于释放了请求过程中各资源分配的内存。*/
    aos_pool_destroy(pool);
    /* 释放之前分配的全局资源。*/
    aos_http_io_deinitialize();
    return 0;
}
