When a timeout occurs, this causes libcurl to jump from the signal handler back into the library with a sigsetjmp, which effectively causes libcurl to continue running within the signal handler.Consider building libcurl with c-ares support to enable asynchronous DNS lookups, which enables nice timeouts for name resolv... 阅148 转0 评0 公众公开 15-06-29 11:26 |
Libcurl多线程crash问题。在官方的Multi-threading Issues描述中并没有提及curl_global_init[4-5]的线程安全问题，而在curl_global_init(3)的接口描述中，提及了curl_global_init是非线程安全的。例如，可以这样初始化：static bool bInit = false; if (bInit == false) { bInit= true; curl_global_init(CURL_GLOBAL_ALL); } ... 阅425 转0 评0 公众公开 15-06-29 11:25 |
else timeout = timeoutms;php curl_setopt($ch, CURLOPT_NOSIGNAL, 1);If you want cURL to timeout in less than one second, you can use CURLOPT_TIMEOUT_MS, although there is a bug/”feature” on “Unix-like systems” that causes libcurl to timeout immediately if the value is <1000 ms with the error "cURL Erro... 阅3540 转3 评0 公众公开 15-06-29 11:25 |

libcurl有个默认的保护机制，检测如果curl_global_init没有在curl_easy_perform之前被调用，那么libcurl会猜测该使用的初始化模式来执行程序。你可能设置错误的libcurl选项，误解了libcurl某些选项的实际作用，或者远程服务器返回libcurl一个非标准的应答。你可以组合多种认证方式，libcurl会以合理的方式处理 curl_easy_setopt(easyhandle, CU... 阅99 转0 评0 公众公开 15-06-24 18:25 |
