requests over the wire (e.g., cURL, sockets, PHP’s stream wrapper, non-blocking event loops like React, etc.). • Guzzle makes it so that you no longer need to fool around with cURL options, stream contexts your system’s php.ini. 3. To use the cURL handler, you must have a recent version of cURL >= 7.16.2 compiled with OpenSSL and zlib. Note: Guzzle no longer requires cURL in order to send HTTP requests. Guzzle Guzzle will use the PHP stream wrapper to send HTTP requests if cURL is not installed. Alternatively, you can provide your own HTTP handler used to send requests. 1.1.2 Installation The recommended way

required). The following optional packages may be useful: • pycurl is used by the optional tornado.curl_httpclient. Libcurl version 7.22 or higher is required. • Twisted may be used with the classes in interfaces. This module defines a common interface shared by two implementations, simple_httpclient and curl_httpclient. Applications may either instantiate their chosen implementation class directly or use for most users’ needs. However, some applications may wish to switch to curl_httpclient for reasons such as the following: • curl_httpclient has some features not found in simple_httpclient, including

FindHello.cmake 模块。 一，使用 FindCURL 模块 在/backup/cmake 目录建立 t5 目录，用于存放我们的 CURL 的例子。 建立 src 目录，并建立 src/main.c，内容如下： #include <curl/curl.h> #include #include #include FILE *fp; char * path = “/tmp/curl-test”; const char * mode = “w”; fp = fopen(path,mode); curl_global_init(CURL_GLOBAL_ALL); CURLcode res; CURL *curl = curl_easy_init(); curl_easy_setopt(curl, CURLOPT_URL, “http://www linux-ren.org”); curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data); curl_easy_setopt(curl, CURLOPT_VERBOSE, 1); res = curl_easy_perform(curl); curl_easy_cleanup(curl); } 这段代码的作用是通过 curl 取回 www.linux-ren
