一、简单介绍
在百度AI智能平台网站购买天文气象API服务。
购买完了以后，在控制台会看到购买信息。
二、使用方法
可通过AppCode或API签名的方式调用。两种调用方式都需要在请求中添加名为X-Bce-Signature的请求头（Header），该请求头的值AppCode或API签名的方式不同。
签名中需要用到的AppCode或AccessKey/AppSecret可在云市场的已购服务列表中已购买的API商品的订单详情页获得。
这里我们简单直接使用AppCode方式调用：
使用AppCode方式调用API较为简单，只要将AppCode以特定的格式放置于X-Bce-Signature请求头中即可。具体格式为"AppCode/" + AppCode值。如AppCode值为6f4ac66971454093bcceb34521bb541e，那么X-Bce-Signature的值为AppCode/6f4ac66971454093bcceb34521bb541e。
URL：
https://jisuweather.api.bdymkt.com/weather/query
后面拼接参数city、cityid、citycode、location等 （注意，其中一个即可，不是所有都要拼接）
例如：
String Url = "https://jisuweather.api.bdymkt.com/weather/query?location="+location+"";
或者
String Url = "https://jisuweather.api.bdymkt.com/weather/query?citycode="+citycode+"";
三、代码实现
public String getWeatherByLocaltion(String location){
String Url = "https://jisuweather.api.bdymkt.com/weather/query?location="+location+"";
StringBuffer sb = null;
try {
URL url = new URL(Url);
HttpURLConnection httpUrlConn = (HttpURLConnection) url.openConnection();
httpUrlConn.setDoInput(true);
httpUrlConn.setRequestMethod("GET");
//设置请求头 后面是你的AppCode
httpUrlConn.setRequestProperty("X-Bce-Signature","AppCode/********************");
//httpUrlConn.connect(); 可要 可不要
// 获取输入流
InputStream inputStream = httpUrlConn.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
// 读取返回结果
sb = new StringBuffer();
String str = null;
while ((str = bufferedReader.readLine()) != null) {
sb.append(str);
}
// 释放资源
bufferedReader.close();
inputStreamReader.close();
inputStream.close();
httpUrlConn.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
String str = sb.toString();
return dealWeatherStr(str);
}
public String getWeatherByCitycode(String citycode){
String Url = "https://jisuweather.api.bdymkt.com/weather/query?citycode="+citycode+"";
StringBuffer sb = null;
try {
URL url = new URL(Url);
HttpURLConnection httpUrlConn = (HttpURLConnection) url.openConnection();
httpUrlConn.setDoInput(true);
httpUrlConn.setRequestMethod("GET");
//设置请求头
httpUrlConn.setRequestProperty("X-Bce-Signature","AppCode/0a7f170702e341f6b3cbd8a4e8274cb9");
//httpUrlConn.connect(); 可要 可不要
// 获取输入流
InputStream inputStream = httpUrlConn.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
// 读取返回结果
sb = new StringBuffer();
String str = null;
while ((str = bufferedReader.readLine()) != null) {
sb.append(str);
}
// 释放资源
bufferedReader.close();
inputStreamReader.close();
inputStream.close();
httpUrlConn.disconnect();
} catch (Exception e) {
e.printStackTrace();
}
String str = sb.toString();
return dealWeatherStr(str);
}
