Curl常用参数

1. CURLOPT_FAILONERROR

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FAILONERROR, long fail);

当http code >= 400时,默认是返回页面。通过这个把fail设置为1,perform执行的请求会是失败。

https://curl.se/libcurl/c/CURLOPT_FAILONERROR.html

代码语言:javascript复制
CURL *curl = curl_easy_init();
if(curl) {
  CURLcode ret;
  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
  curl_easy_setopt(curl, CURLOPT_FAILONERROR, 1L);
  ret = curl_easy_perform(curl);
  if(ret == CURLE_HTTP_RETURNED_ERROR) {
    /* an HTTP response error problem */
  }
}

2. 速度限制
