Windows系統(tǒng)下源代碼下載編譯、安裝方式如下：
https://blog.csdn.net/fxbjye/article/details/89152849
編譯后得到庫(kù)文件，把這兩個(gè)文件復(fù)制到項(xiàng)目文件中，

修改項(xiàng)目文件的屬性，

修改附加依賴項(xiàng)：

輸入代碼：

#include <stdio.h> #include <string.h> #include <curl.h> #define MAX_BUF 65536 char wr_buf[MAX_BUF + 1]; int wr_index;/* * Write data callback function (called within the context of * curl_easy_perform. */ size_t write_data(void *buffer, size_t size, size_t nmemb, void *userp) {int segsize = size * nmemb;/* Check to see if this data exceeds the size of our buffer. If so,* set the user-defined context value and return 0 to indicate a* problem to curl.*/if (wr_index + segsize > MAX_BUF) {*(int *)userp = 1;return 0;}/* Copy the data from the curl buffer into our buffer */memcpy((void *)&wr_buf[wr_index], buffer, (size_t)segsize);/* Update the write index */wr_index += segsize;/* Null terminate the buffer */wr_buf[wr_index] = 0;/* Return the number of bytes received, indicating to curl that all is okay */return segsize; }/* * Simple curl application to read the index.html file from a Web site. */ int main(void) {CURL *curl;CURLcode ret;int wr_error;wr_error = 0;wr_index = 0;/* First step, init curl */curl = curl_easy_init();if (!curl) {printf("couldn't init curl\n");return 0;}/* Tell curl the URL of the file we're going to retrieve */curl_easy_setopt(curl, CURLOPT_URL, "www.baidu.com");/* Tell curl that we'll receive data to the function write_data, and* also provide it with a context pointer for our error return.*/curl_easy_setopt(curl, CURLOPT_WRITEDATA, (void *)&wr_error);curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data);/* Allow curl to perform the action */ret = curl_easy_perform(curl);printf("ret = %d (write_error = %d)\n", ret, wr_error);/* Emit the page if curl indicates that no errors occurred */if (ret == 0) printf("%s\n", wr_buf);curl_easy_cleanup(curl);return 0; }
