北京天气查询API(北京天气查询2345)
本文目录一览:
前期的准备工作:
一、申请API(拿好appid和private_key)
二、解读《SmartWeatherAPILite WebAPI版接口使用说明书》
三、准备好areaid、type、date、appid、urlencode($key)(注意,这里经加密的key是需要encodeurl之后的才能成为接口链接的一部分)
好了下面的编码开始:
1、从附件中的areaid_list中找到你想要的地方的areaid,并且选择要查询天气的类型
NSString *areaid = @"101010100";
NSString *type =
@"index_f";
/**
* 官方文档更新的数据类型号
* 指数:index_f(基础接口);index_v(常规接口)
3天预报:forecast_f(基础接口);forecast_v(常规接口)
*
*/
2、获得当前天气date
NSDate
*_date = [NSDate date];
NSDateFormatter *dateFormatter =
[[NSDateFormatter alloc] init];
[dateFormatter
setDateFormat:@"yyyyMMddHHmmss"];//注意日期的格式
NSString *date =
[[dateFormatter stringFromDate:_date]
substringToIndex:12];//用到的精确到分,24小时制60分钟制
3、申请的appid,和private_key
NSString *appid =
@"15ds45s13a465s";//这里是楼主随便输入的,瞎编的
NSString *private_key =
@"46s4ds_SmartWeatherAPI_45s44d6";//也是瞎编的
4、算出经过urlencode后的key,这步比较重要,步骤也多,请耐心看完。
在原来的的基础上是在PHP的环境中算出的,代码如下,可在“
”下进行算法的检验
echo
urlencode(base64_encode(hash_hmac('sha1', " ;type=index_fdate=201409041509appid=15ds45s13a465s",
"46s4ds_SmartWeatherAPI_45s44d6",
TRUE)));
首先定义得到public_key和API的方法,还有就是对key进行encodeurl操作的方法
注意,这里的方法都是被我定义在getTime的类里面,后面是在main中实例化出来的
//获得publicky
- (NSString*)
getPublicKey:(NSString*)areaid :(NSString*)type :(NSString*)date
:(NSString*)appid {
NSString *Key = [[NSString alloc]
initWithFormat:@";type=%@date=%@appid=%@",
areaid, type, [date substringToIndex:12], appid];
return
Key;
}
//获得完整的API
- (NSString*) getAPI:(NSString*)areaid
:(NSString*)type :(NSString*)date :(NSString*)appid :(NSString*)key
{
NSString *API = [[NSString alloc]
initWithFormat:@";type=%@date=%@appid=%@key=%@",
areaid, type, [date substringToIndex:12], [appid substringToIndex:6],
key];
//-------------这里需要主要的是只需要appid的前6位!!!
return
API;
}
//将获得的key进性urlencode操作
- (NSString
*)stringByEncodingURLFormat:(NSString*)_key{
NSString *encodedString
= (__bridge NSString
*)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,(CFStringRef)_key,
nil, (CFStringRef) @"!$'()*+,-./:;=?@_~%#[]",
kCFStringEncodingUTF8);
//由于ARC的存在,这里的转换需要添加__bridge,原因我不明。求大神讲解
return
encodedString;
}
重点来了,在oc下的算法如下,记得把附件的Base64.h
加进来并引用到工程里面
//对publickey和privatekey进行加密
- (NSString *)
hmacSha1:(NSString*)public_key :(NSString*)private_key{
NSData*
secretData = [private_key
dataUsingEncoding:NSUTF8StringEncoding];
NSData* stringData = [public_key
dataUsingEncoding:NSUTF8StringEncoding];
const void* keyBytes =
[secretData bytes];
const void* dataBytes = [stringData
bytes];
///#define CC_SHA1_DIGEST_LENGTH 20 /* digest
length in bytes */
void* outs =
malloc(CC_SHA1_DIGEST_LENGTH);
CCHmac(kCCHmacAlgSHA1, keyBytes,
[secretData length], dataBytes, [stringData length], outs);
//
Soluion 1
NSData* signatureData = [NSData dataWithBytesNoCopy:outs
length:CC_SHA1_DIGEST_LENGTH freeWhenDone:YES];
return
[signatureData
base64EncodedString];
}
这里只是初步算出来的key,还未encodeurl,链接不能被浏览器识别,所以现在经过算法得到的_key还有一步操作才能的到真正的key。
NSString *_key = [getTime hmacSha1:[getTime
getPublicKey:areaid :type :date :appid] :private_key];
NSString *key =
[getTime
stringByEncodingURLFormat:_key];
最后一步了吧!拼接API
NSString *weatherAPI = [getTime getAPI:areaid :type :date
:appid
:key];
//OK,我们的API就可以用啦。
最后,通过API返回的值是JSON文件,通过解析,就能得到我们想要的数据了,下面拿一个开发的接口举例
NSDictionary *weatherDic = [getTime
getWeatherDic:@""];
// weatherDic字典中存放的数据也是字典型,从它里面通过键值取值
NSDictionary
*weatherInfo = [weatherDic
objectForKey:@"weatherinfo"];
NSLog(@"今天是 %@ %@ %@ 的天气状况是:%@ %@ -
%@",[newDateOne substringWithRange:NSMakeRange(0, 4)],[newDateOne
substringWithRange:NSMakeRange(4, 2)] ,[newDateOne
substringWithRange:NSMakeRange(6, 2)],[weatherInfo
objectForKey:@"weather"],[weatherInfo objectForKey:@"temp1"],[weatherInfo
objectForKey:@"temp2"]);
输出:2014-09-04 23:40:23.243
WeatherAPP[5688:201108] 今天是 2014-09-04 的天气状况是:晴 17℃ - 30℃
weatherInfo字典里面的内容是---{"weatherinfo":{"city":"北京","cityid":"101010100","temp1":"17℃","temp2":"30℃","weather":"晴","img1":"n0.gif","img2":"d0.gif","ptime":"18:00"}}
因微信公共号提供城市天气预报服务,发现网山天气预报接口和环境数据接口方面资料比较乱,而且有不少内容已经失效,下面内容由过程日志整理形成,希望可用得上。
一 天气预报
国内的天气预报数据,主要是国家气象局和国外两个来源(指数据来源)。
国外方面主要是雅虎(XML格式,谷歌已经停掉了自家的天气API);
国内数据由国家气象局提供(JSON格式)。
在知乎看到过一篇专业人士评论,雅虎可以提供全球范围的且非常精细的天气数据(小时级更新),但主要是通过计算机自动生成。而国家气象局则是各地经验丰富的专家人士结合计算机综合分析得出,在准确性上更胜一筹。我就这样信了!
国家气象局接口资源及用法
气象局的天气预报主页:移动版普通版 ,仔细挖掘这两个地址可以发现很多好东西哦。
特点:接口多,来自weather.com.cn和mobile.weather.com.cn都有,次数不限制,服务稳定,功能全面,优先推荐。
1. 实时天气接口
有多个接口,好像差别不大:
实时天气1:
实时天气2:
实时天气3(带时间戳):
2. 一周天气预报接口
7天预报数据 URL:
该接口来源气象局移动版网站,目测数据最为精确,详细接口格式如下:

3. 我们来写个demo,代码如下:
package com.example.administrator.jsontest;
public class MainActivity extends Activity {
private Button button;
private TextView textView;
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case 0:
String re = (String) msg.obj;
textView.setText(re);
break;
}
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.button);
textView = (TextView) findViewById(R.id.textView);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i("TAG", "点击了Button");
sendRequestWithHttpClient();
}
});
}
private void sendRequestWithHttpClient() {
new Thread(new Runnable() {
@Override
public void run() {
HttpURLConnection connection = null;
try {
URL url = new URL("南昌output=jsonak=8ixCCFzlBB617YX7tONI2P5Bmcode=1C:6B:42:33:E8:A6:DC:A2:11:6E:26:EC:84:BD:42:E3:8E:6B:57:9A;com.example.administrator.jsontest");
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setConnectTimeout(5000);
connection.setReadTimeout(5000);
InputStream in = connection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder response = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
response.append(line);
}
Log.i("TAG", response.toString()); parseJSONObjectOrJSONArray(response.toString());
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}).start();
}
//解析JSON数据
private void parseJSONObjectOrJSONArray(String jsonData) {
try {
String count = "";
JSONObject jsonObject = new JSONObject(jsonData);
JSONArray jsonArray = jsonObject.getJSONArray("results");
if (jsonArray.length() 0) {
JSONObject object = jsonArray.getJSONObject(0);
String city = object.optString("currentCity");
JSONArray array = object.getJSONArray("weather_data");
for (int i = 0; i array.length(); i++) {
JSONObject jsonObject1 = array.getJSONObject(i);
String dateDay = jsonObject1.optString("date");
String weather = jsonObject1.optString("weather");
String wind = jsonObject1.optString("wind");
String temperature = jsonObject1.optString("temperature");
count =count +"\n"+ dateDay + " " + weather + " " + wind + " " + temperature;
Log.i("AAA",count);
}
Message message = new Message();
message.what = 0;
message.obj = count;
handler.sendMessage(message);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
