返回格式：json
请求方式：http get/post
请求示例：http://apis.juhe.cn/simpleWeather/query?city=%E8%8B%8F%E5%B7%9E&key=
接口备注：通过城市名称或城市ID查询天气预报情况
请求参数说明：
| | 名称 | 必填 | 类型 | 说明 | | ---- | ---- | ---- | ------ | ------------------------------------------------------------ | | | city | 是 | string | 要查询的城市名称/id，城市名称如：温州、上海、北京，需要utf8 urlencode | | | key | 是 | string | 在个人中心->我的数据,接口名称上方查看 |
返回参数说明：
| | 名称 | 类型 | 说明 | | ---- | ----------- | ------ | ------------------------- | | | error_code | int | 返回码，0为查询成功 | | | reason | string | 返回说明 | | | result | string | 返回结果集 | | | - | - | - | | | realtime | - | 当前天气详情情况 | | | info | string | 天气情况，如：晴、多云 | | | wid | string | 天气标识id，可参考小接口2 | | | temperature | string | 温度，可能为空 | | | humidity | string | 湿度，可能为空 | | | direct | string | 风向，可能为空 | | | power | string | 风力，可能为空 | | | aqi | string | 空气质量指数，可能为空 | | | - | - | - | | | future | - | 近5天天气情况 | | | date | string | 日期 | | | temperature | string | 温度，最低温/最高温 | | | weather | string | 天气情况 | | | direct | string | 风向 |
JSON返回示例：

}Linux下通过C获取天气
通过curl命令进行http get请求，并使用cJSON库解析返回结果
cJSON库：https://sourceforge.net/projects/cjson/

目前读取popen结果使用最大缓存102400，最好修改代码将缓存改小，重复读取。
#include <stdio.h>
#include "include.h"int popenCmd(char *cmd, char *result)
{//运行命令,将结果保存到resultsFILE *fp = popen(cmd, "r");if (NULL == fp){printf("打开 file命令失败n");goto err;}//将结果读取到results字符串数组中fgets(result, RESULT_BUF_LEN, fp);if (fp){pclose(fp);fp = NULL;}return 0;err:if (fp){pclose(fp);fp = NULL;}return -1;
}include.h
#include "cJSON.h"#define MAX_LEN 256
#define RESULT_BUF_LEN 102400//执行命令,将命令结果保存到result
int popenCmd(char *cmd, char *result);
#编译命令：
gcc weather.c cJSON.c tools.c -lm -o weather
./weather#输入结果:
天气预报
1.北京
2.上海
3.福州
输入序号获取天气:
1
查询城市 :北京
温度：25度
湿度：82度
天气：多云
风向：东北风
