libcurl 的初步使用

一、libcurl的http使用

1.libcurl全局初始化与反初始化

初始化：

CURL_EXTERN CURLcode curl_global_init(long flags);

反初始化：

CURL_EXTERN void curl_global_cleanup(void);

curl_global_init(CURL_GLOBAL_ALL);

curl_global_cleanup( );

这是全局初始化函数，并不是线程安全的，只能全局调用一次。

2.libcurl初始化与反初始化

CURL_EXTERN CURL *curl_easy_init(void);

CURL_EXTERN void curl_easy_cleanup(CURL *curl);

局部初始化，可以多次调用。

3.设置CURL指针的属性

CURL_EXTERN CURLcode curl_easy_setopt(CURL *curl, CURLoption option, ...);

4.执行CURL请求

CURL_EXTERN CURLcode curl_easy_perform(CURL *curl);

5.具体的调用流程：

        (1)全局初始化(仅一次)：curl_global_init(CURL_GLOBAL_ALL);

        (2)局部初始化：curl_easy_init( );

        (3)设置CURL属性：curl_easy_setopt(m_lpCurl, CURLOPT_URL, lpUrl);

        (4)执行请求：curl_easy_perform(m_lpCurl);

        (5)局部反初始化：curl_easy_cleanup(m_lpCurl);

        (6)全局反初始化：curl_global_cleanup( );

6.基本的http属性字段的设置:

   (1).设置本次连接的等待时间,仅仅是HTTP连接   

   crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_CONNECTTIMEOUT, u32WaitTime);

   (2)设置URL地址

    crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_URL, lpUrl);

   (3)设置http的头回调函数

    crulCode = curl_easy_setopt( m_lpCurl, CURLOPT_HEADERFUNCTION, HeadCallBack );

   (4)设置头回调函数的上下文指针

    crulCode = curl_easy_setopt( m_lpCurl, CURLOPT_HEADERDATA, this );

   (5)设置请求方式为post

    crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_POST, 1L);

   (6)设置post所携带的数据

    crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_POSTFIELDS, lpInBuffer);

   (7)设置post数据的大小

    crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_POSTFIELDSIZE, u32InSize);

   (8))设置http请求的返回数据的回调函数的上下文指针

    crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_WRITEDATA, (void*)m_lpBody);

   (9)设置http请求的返回数据的回调函数，body数据的回调

    crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_WRITEFUNCTION, BodyCallBack); //回调http的响应数据

7.https相关属性设置

(1)设置SSL证书的路径

  crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_CAINFO, s8KeyPathString);

(2)设置是否验证SSL证书
crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_SSL_VERIFYPEER, TRUE);

(3)设置SSL证书版本
crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_SSLVERSION , CURL_SSLVERSION_TLSv1_1);

(4)设置是否验证host的证书
crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_SSL_VERIFYHOST, FALSE);

(5)设置用户名密码
crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_USERPWD, s8Param);

(6)设置认证方式为DIGEST
crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_HTTPAUTH, (long)CURLAUTH_DIGEST);

(7)设置验证方式BASIC
crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_HTTPAUTH, (long)CURLAUTH_BASIC);

(8)加入curl的标示头
crulCode = curl_easy_setopt(m_lpCurl, CURLOPT_USERAGENT, "curl/7.47.1");

(9)设置XHASH,CHASH,XHASH等属性值

lpCurlList = curl_slist_append(lpCurlList, GetSHash( ));
lpCurlList = curl_slist_append(lpCurlList, GetCHash( ));
lpCurlList = curl_slist_append(lpCurlList, GetXHash( ));
curl_easy_setopt(m_lpCurl, CURLOPT_HTTPHEADER, lpCurlList);

8.上传文件相关设置

(1)设置上传的文件路径

struct curl_httppost *post = NULL;
struct curl_httppost *last = NULL;
eFormRet = curl_formadd(&post, &last, CURLFORM_COPYNAME, "file", CURLFORM_FILE, lpInBuffer, CURLFORM_END) ;

9.代码示例:
