文件上传是调用oss_append_object_from_file， 怎么把md5用起来？是放在Content-MD5还是调用后从resp_headers读md5跟本地文件的md5比较？有Demo吗？
aos_table_t *resp_headers使用后怎么释放？

调用oss_head_object()，当object不存在的时候，返回的status如下：

req_id: 56DCFA06DA14FDFF1BC21924
error_code: "UnkonwnError"
error_msg: ""

这里面有两个问题：

1. 这个error code反映不了到底这个请求是因为什么原因失败
2. error code有一处typo，应该是UnknownError

Do you have a script to build oss-c-sdk targeting android and ios?

这种情况 该如何处理？ 需要怎样设置 超时时长？ aliyun-oss-c-sdk-3.5.0/oss_c_sdk/aos_transport.c:456 transport failure curl code:28 error:Timeout was reached

如图：

已经安装了 mxml 的 rpm 安装包

when call aos_request_get, request will be reset to init status.
If we reset request before add to requestStackG, we can release unneed memory.

// related codes:

CURL *aos_request_get()
{
CURL *request = NULL;

apr_thread_mutex_lock(requestStackMutexG);
if (requestStackCountG > 0) {
    request = requestStackG[--requestStackCountG];
}
apr_thread_mutex_unlock(requestStackMutexG);

// If we got one, deinitialize it for re-use
if (request) {
    curl_easy_reset(request);
}
else {
    request = curl_easy_init();
}

return request;

}

void request_release(CURL *request)
{
apr_thread_mutex_lock(requestStackMutexG);

// If the request stack is full, destroy this one
// else put this one at the front of the request stack; we do this because
// we want the most-recently-used curl handle to be re-used on the next
// request, to maximize our chances of re-using a TCP connection before it
// times out
if (requestStackCountG == AOS_REQUEST_STACK_SIZE) {
    apr_thread_mutex_unlock(requestStackMutexG);
    curl_easy_cleanup(request);
}
else {
    requestStackG[requestStackCountG++] = request;
    apr_thread_mutex_unlock(requestStackMutexG);
}

}

如下：

使用 oss_resumable_upload_file （开启 checkpoint） 上传文件时存在内存泄漏问题。

重现：
使用官网“断点续传”例子编译运行。https://help.aliyun.com/document_detail/90219.html?spm=a2c4g.11174283.6.1121.40087da23nKquN

typedef void (*oss_progress_callback)(int64_t consumed_bytes, int64_t total_bytes);
只有进度信息，但没有对象信息，无法知道是哪个对象的进度信息，希望加一个void*参数进去。这样更加合理方便

调用 OSS C API oss_get_object_to_buffer 出错

struct aos_status_s {
int code; // > 0 http code
char *error_code; // can't modify
char *error_msg; // can't modify
char *req_id; // can't modify
};

aos_status_s 结构反馈的错误信息：

code -992
error_code HttpIoError
error_msg Timeout
req_id 58EC0CD00731DD416E838728

aos_should_retry 函数的判断是否有BUG
应该判断 int code 的值，而不是判断 error_code

目前已知oss_request_options_create 和 aos_http_controller_create没有相应的资源释放函数。

从官网上下载的c sdk 3.5 for windows，调用oss_resumable_upload_file或者oss_resumable_download_file接口时，传入的回掉函数只有2个参数分别表示已经处理的和全部的数据量。这种在多线程调用的时候，怎么区分哪个进度是哪个正在进行中的任务呢？

	aos_string_t object;
	int is_cname = 0;
	oss_request_options_t *options = NULL;
	aos_table_t *params = NULL;
	aos_table_t *resp_headers = NULL;
	aos_table_t *headers = NULL;
	aos_status_t *s = NULL;
	aos_string_t file;
	aos_pool_t *p = NULL;
	aos_string_t bucket;

	aos_pool_create(&p, NULL);
	options = oss_request_options_create(p);
	initRequestOptions(options, is_cname);

	headers = aos_table_make(p, 0);

	aos_str_set(&bucket, bucketName.c_str());
	aos_str_set(&object, objectName.c_str());
	aos_str_set(&file, filePath.c_str());

	if (resumable)
	{
		oss_resumable_clt_params_t *clt_params;

	}
	else
	{
		s = oss_do_get_object_to_file(options, &bucket, &object, headers, 0,
			&file, downloadCallback, 0);
	}

我上面的断点续传没写错吧。为什么会从头开始下载文件呢，我看了你的demo写的。哪里写错了吗

--interface INTERFACE Use network INTERFACE (or address)

Hi, after i installed latest oss c sdk, i found oss_resumable.h is not installed into /usr/local/include, which could cause my program fail to compile.

Then I checked the CMakeLists.txt , i found oss_resumable.h missed in INSTALL part, please add it

编译后出现这样的一句话怎么解决：
C:/Windows/System32/libcurl.dll: file not recognized: file format not recognized

请问aliyun-oss-c-sdk什么时候支持64位Windows库？

上传采用curl没有启用CURLOPT_TCP_KEEPALIVE，会导致应用占用大量端口

按照官网教程，在centos7环境下安装完依赖：

yum install cmake
yum install curl-devel apr-devel apr-util-devel  mxml mxml-devel

安装依赖如下：

下载oss sdk 3.10.0后，cmake . 前未出现错误，make时报了如下错误：

aliyun-oss-c-sdk版本：3.6.0
libcurl版本：7.63.0
问题：当我用aos_http_io_initialize()初始化网络和其他资源后，先后发起一个Content-Length为0的PUT请求（比如设置bucket的ACL）和一个GET请求，毋庸置疑，这两个HTTP请求会共用同一条TCP连接。发送第一个PUT请求时，虽然设置了”Content-Length:0“，并没有主动设置“Transfer-Encoding:chunked”（我查阅了代码），但是在发送的包里还是发现了“Transfer-Encoding:chunked”这个header，这导致服务器端忽略了Content-length，从而不能正确区分两个HTTP请求的边界，导致第二个请求失败。（当PUT请求的Content-length不为0时（比如分块上传），并没有发现“Transfer-Encoding”header）。

解决：我查阅了libcurl官方文档，发现对于“Transfer-Encoding”有这样的描述：

Enforcing chunked transfer-encoding
By making sure a request uses the custom header "Transfer-Encoding: chunked" when doing a non-GET HTTP operation, libcurl will switch over to "chunked" upload, even though the size of the data to upload might be known. By default, libcurl usually switches over to chunked upload automatically if the upload data size is unknown.

对于PUT请求，有这样的描述：

A parameter set to 1 tells the library to use HTTP PUT to transfer data. The data should be set with CURLOPT_READDATA and CURLOPT_INFILESIZE.

因此我在aos_transport.c的aos_curl_transport_setup()函数中添加了一句：

switch (t->req->method) {
        case HTTP_HEAD:
            curl_easy_setopt_safe(CURLOPT_NOBODY, 1);
            break;
        case HTTP_PUT:
            curl_easy_setopt_safe(CURLOPT_UPLOAD, 1);
            /* modify here */
            curl_easy_setopt_safe(CURLOPT_INFILESIZE, t->req->body_len);
            break;
        case HTTP_POST:
            curl_easy_setopt_safe(CURLOPT_POST, 1);
            break;
        case HTTP_DELETE:
            curl_easy_setopt_safe(CURLOPT_CUSTOMREQUEST, "DELETE");
            break;
        default: // HTTP_GET
            break;
    }

现在它正常工作了，我觉得需要报告一下。

使用https://github.com/baiyubin/aliyun-oss-c-sdk-sample?spm=a2c4g.11186623.2.17.xrhV7M
这里面的例子运行多片上传命令，大概率返回400错误，请问是什么原因？

c sdk V3.5.0 断点续传下载时出现如题的错误，麻烦请问下是什么原因造成的

oss-c-sdk 使用的版本是 3.5.0的
code = CURLE_OPERATION_TIMEDOUT (28)，实际上url地址是完全正确的

aliyun-oss-c-sdk 从哪个版本开始支持ipv6

void put_object_from_file() 实现上传本地文件到OSS介绍中描述：
通过oss_put_object_from_file接口，并指定fliepath参数，可以实现上传一个本地文件到OSS。

实际上，api提供的oss_put_object_from_file接口，并没有这个path参数，该如何解决。

[问题描述在：官方问题描述链接
问题代码在：aliyun-oss-c-sdk / oss_c_sdk_sample / oss_put_object_sample.c

请问需要如何解决？

參考鏈接 https://help.aliyun.com/document_detail/90219.html?spm=a2c4g.11186623.6.1137.7fd42989fIdVD0 和 oss_c_sdk_test代碼，當設置 proxy 選項時：

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);
    aos_str_set(&options->config->proxy_host, proxy_host);
    aos_str_set(&options->config->proxy_user, proxy_user);
    aos_str_set(&options->config->proxy_passwd, proxy_passwd);
    options->config->proxy_port = atoi(proxy_port);

    /* 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);
    options->ctl->options = aos_http_request_options_create(options->pool);
    oss_config_resolve(options->pool, options->config, options->ctl);
    options->ctl->options->verify_ssl = AOS_FALSE;
}

調用斷點續傳 api：

    /* 断点续传。*/
    clt_params = oss_create_resumable_clt_params_content(pool, 1024 * 100, 3, AOS_TRUE, NULL);
    resp_status = oss_resumable_upload_file(oss_client_options, &bucket, &object, &file, headers, NULL, clt_params, NULL, &resp_headers, &resp_body);

將出現以下錯誤

aliyun-oss-c-sdk/oss_c_sdk/aos_transport.c:497 transport failure curl code:28 error:Timeout was reached
resumable upload failed

簡單看了下源代碼，猜測可能是沒有將 proxy 相關選項傳遞給 checkpoint content 的定義中。

API中的URL params用的是apr_table_t，如oss_do_put_object_from_buffer()，oss_do_get_object_to_buffer()等。apr_table_get/set不区分key的大小写，如果外部传入的params的key与oss定义key的有大小写不敏感匹配（如EXPires）时，在对params table进行set时可能覆盖原value，并无法改写key的大小写。这可能导致一些不符合预期的访问。

crc64 code uses macro ONCE() to do dynamic initialization, and ONCE() is defined as

/* Run the init() function exactly once.  If pthread.h is not included, then
   this macro will use a simple static state variable for the purpose, which is
   not thread-safe.  The init function must be of the type void init(void). */
#ifdef PTHREAD_ONCE_INIT
#  define ONCE(init) \
    do { \
        static pthread_once_t once = PTHREAD_ONCE_INIT; \
        pthread_once(&once, init); \
    } while (0)
#else
#  define ONCE(init) \
    do { \
        static volatile int once = 1; \
        if (once) { \
            if (once++ == 1) { \
                init(); \
                once = 0; \
            } \
            else \
                while (once) \
                    ; \
        } \
    } while (0)
#endif

So it's meant to be defined to use pthread_once() when pthread is available. But aos_crc64.c doesn't include pthread.h from any header files, so even if we have APR_HAVE_PTHREAD_H defined as 1 (from apr.h), pthread.h is not included either. And this may result in infinite loop in multi-thread environments.

I'll submit a PR for this issue.

那rust可以用c的sdk吗
