Question

我正在使用libcurl发送http消息。

我开发了以下函数，其中我启动curl选项，然后执行http消息的发送。以下代码中未激活选项CURLOPT_VERBOSE。但是在执行以下功能时，收到的http消息会显示在详细信息中。我该如何解决这个问题？

http_lightweight_notification(char *msg_out, int msg_out_len)
{
    static CURL *n_curl;
    CURLcode res;
    struct curl_slist *chunk = NULL;
    char *url="http://192.168.1.133:8080";
    char buf[SIGNATURE_LEN + sizeof("Signature: ")] = "Signature: ";
    char *signature = buf + sizeof("Signature: ") - 1;

    if (!msg_out) return -1;
    n_curl = curl_easy_init();
    if (!n_curl) return -1;

    signature_hmac_sha1(msg_out, "anykey", signature);

    chunk = curl_slist_append(chunk, "Content-Type: text/xml; charset=utf-8");
    if (!chunk) return -1;
    chunk = curl_slist_append(chunk, "Accept:");
    if (!chunk) return -1;
    chunk = curl_slist_append(chunk, buf);
    if (!chunk) return -1;

    curl_easy_setopt(n_curl, CURLOPT_URL, url);
    curl_easy_setopt(n_curl, CURLOPT_HTTPHEADER, chunk);
    curl_easy_setopt(n_curl, CURLOPT_TIMEOUT, 30);
    curl_easy_setopt(n_curl, CURLOPT_CONNECTTIMEOUT, 30);

    curl_easy_setopt(n_curl, CURLOPT_POSTFIELDS, msg_out);
    curl_easy_setopt(n_curl, CURLOPT_POSTFIELDSIZE, (long) msg_out_len);

# if 0
    curl_easy_setopt(n_curl, CURLOPT_VERBOSE, 1L);
# endif

    res = curl_easy_perform(n_curl);
    if (chunk) {
        curl_slist_free_all(chunk);
        chunk = NULL;
    }
    curl_easy_cleanup(n_curl);
    curl_global_cleanup();

    if (res) return -1;
    return 0;
}

详细输出是：

Answer 1

这不是详细的输出，而是您收到的内容的正文。

通过将CURLOPT_WRITEFUNCTION设置为接收数据，或者可能将CURLOPT_WRITEDATA设置为不同的FILE *句柄，禁止将内容发送到stdout（这是默认设置）。

显示在getinmemory.c示例中。

Libcurl显示日志消息甚至CURLOPT_VERBOSE都未激活
