在C語(yǔ)言中連接天氣API，語(yǔ)言連通常需要使用網(wǎng)絡(luò )庫（如lib??curl）來(lái)發(fā)送HTTP請求，接天以下是語(yǔ)言連一個(gè)簡(jiǎn)單的示例，展示了如何使用libcurl庫從Op??enWeatherMap API獲取天氣信息。接天

（圖片來(lái)源網(wǎng)絡(luò )，語(yǔ)言連侵刪）

1、接天確保已經(jīng)安裝了libcurl庫，語(yǔ)言連在Ubuntu系統中，接?天可以(yi)使用以下命令安裝：

sudo aptget install libcurl4openssldev

2、語(yǔ)言連創(chuàng )建一個(gè)名為weather.c的接天C文件，并添加以下代碼：

#includ???e <stdio.h>#include <stdlib.h>#include <string.h>#inヾ(′?｀)?clude &l??t;curl/curl.h>// 回調函數，語(yǔ)言連用于處理ヽ(′ー｀)ノ接收到的接天數據size_t write_callback(char *ptr, size_t size, size_t nmemb, void *userdata) {  size_t realsize = size * nmemb; char *buffer = (cha(′?_?`)r *)userdata; memcpy(buffer, ptr, realsize); buffer[realsize] = ''; return realsize;}int main() {  CURL *curl; CURLcode res; char urlヾ(′▽?zhuān)??[] = "https://ap(╯°□°）╯︵ ┻━┻i.open="open"weathermap.org/dat(?????)a/2.5/weather?q=北京&┐(′ー｀)┌;appid=your_api_key&(╯°□°）╯︵ ┻━┻quot;; // 替換為你的API密鑰 char buffer[1024]; curl_(′_ゝ`)glob(′▽?zhuān)?)al_in(′_ゝ`)it(CURL_GLOBAL_DEFAULT); curl = curl_easy_init(); if(curl) {  curl_easy_setopt(curl, CURLOPT_??URL, url); curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, wr(??-)?ite_callback); curl_easy_setopt(curl, CURLOPT_WRITEDATA, buffer); res = curl_easy_perform(curl); if(res != CURLE_OK) {  fprintf(stderr, "curl_easy_perform() failed: %s", curl_easy_strerror??(res)); } else {  pr??intf("Weather information: %s", buffer); } curl_easy_cleanup(curl); } curl_globa??l_cleanup(); return 0;}

3、將your_api_key替換為你在OpenW??eatherMap網(wǎng)站上注冊的語(yǔ)言連API密鑰，如果沒(méi)有API密鑰，接天請先注冊一個(gè)，語(yǔ)言連注意，免費計劃每天有( ?ヮ?)限制的請求次數。

4、編譯并運行程序：

gcc weather.c o weather??? lcur(°o°)l./weather

程序將輸出類(lèi)似以下格式的天氣信息：

Weather information: { "coord":{ "lon&q(′?｀)uot;:116.4074,"lat":39.9042},"weather":[{ "id":803,"main":"Clouds"??,"description":&┐(′д｀)┌quot;broken clouds","icon"(???):"04d"}],"base&q??uot;(′▽?zhuān)?:"stations","main":{ "temp":293.15,"pressure":1012(′ω｀*),"humidity&qu??ot;:81,"temp_min":??2??91.15,"temp_max":295.15},"vi??sibility":16093,"wind":{ &qu??ot;speed":1.1,&(??ヮ?)?*:???quot;deg":300},&quoヽ(′▽?zhuān)?ノt;clouds":{ "all&qu??ot;:75},&??quot;dt":1629459200,"sys":{ "type":2,"id":2019686,"cou??ntry&q??uot;:"C?N","sunrise&quo(′ω｀*)t;:1629422743,"sunset":1629478177},"??;timヽ(′ー｀)ノezone"(//ω//):86(′?_?`)400??,"id":101010100,"name":"??Beijing","cod":200}
