1.android端免费获取天气信息的服务器接口有么

2.iOS开发，想知道国家气象局api返回过来的天气数据将天气总共描述为几种类型，

3.我想知道大连未来五天的天气，最好是发过来你信息的来源的

4.如何使用中国气象局API开发天气APP

html天气插件代码_天气预报代码html代码

取天气预报需要连接网络取，思路如下：

1.通过HTTP协议到达某个网站取到天气预报信息，是XML或HTML格式

2.解析XML或HTML格式的数据，将天气预报信息解析出来

3.显示出来

例如获取://.nmc.gov.cn/的信息，解析，显示就可以了

但是这种当这个网站的数据格式更新后，你也要更新你的解析处理程序部分

android端免费获取天气信息的服务器接口有么

你这个不是接口，只是个网页地址。

我找到另外一个天气预报的接口：

://.webxml.cn/WebServices/WeatherWebService.asmx

只要在项目中添加Web引用：

按照这个做：

然后人就可以实例化这个对象：

调用对应的方法就可以获取接口中的信息了。

直接在IE或其它浏览器中打开这接口网址：

://.webxml.cn/WebServices/WeatherWebService.asmx

可以看到那些方法的使用说明。

还是不会就不应该了。为了这15分，可以加我好友再问。

iOS开发，想知道国家气象局api返回过来的天气数据将天气总共描述为几种类型，

中国国家气象局提供了获取所在城市天气预报信息接口。通过这个接口，我们就可以获取天气信息了。

关于获取天气预报的实例参考android学习手册，里面有源码。android学习手册包含9个章节，108个例子，源码文档随便看，例子都是可交互，可运行，源码用android studio目录结构，高亮显示代码，文档都用文档结构图显示，可以快速定位。360手机助手中下载,图标上有贝壳

中国国家气象局天气预报接口总共提供了三个：

://.weather.cn/data/sk/101010100.html

://.weather.cn/data/cityinfo/101010100.html

://m.weather.cn/data/101010100.html

注：上面接口2014.3.4日已不再更新。换成这个：://m.weather.cn/atad/101230201.html。各位看34楼。在此感谢tdwll和黄晓佳cobish。

最详细的信息来自第三个接口。上面url中的101010100是城市代码，这里是北京的城市代码。只需要改变城市代码，就可以得到所在城市的天气信息。笔者在福州，所以选择的城市代码是福州101230101。

在浏览器上输入url：://m.weather.cn/data/101230101.html得到信息，天气信息是json的数据格式，数据如下：

{"weatherinfo":{"city":"福州","city_en":"fuzhou","date_y":"2012年5月14日","date":"","week":"星期一","fchh":"08","cityid":"101230101","temp1":"29℃~23℃","temp2":"26℃~20℃","temp3":"24℃~20℃","temp4":"25℃~20℃","temp5":"24℃~21℃","temp6":"25℃~22℃","tempF1":"84.2℉~73.4℉","tempF2":"78.8℉~68℉","tempF3":"75.2℉~68℉","tempF4":"77℉~68℉","tempF5":"75.2℉~69.8℉","tempF6":"77℉~71.6℉","weather1":"阵雨转中雨","weather2":"中雨转小雨","weather3":"小雨","weather4":"小雨","weather5":"小雨转阵雨","weather6":"阵雨转小雨","img1":"3","img2":"8","img3":"8","img4":"7","img5":"7","img6":"99","img7":"7","img8":"99","img9":"7","img10":"3","img11":"3","img12":"7","img_single":"3","img_title1":"阵雨","img_title2":"中雨","img_title3":"中雨","img_title4":"小雨","img_title5":"小雨","img_title6":"小雨","img_title7":"小雨","img_title8":"小雨","img_title9":"小雨","img_title10":"阵雨","img_title11":"阵雨","img_title12":"小雨","img_title_single":"阵雨","wind1":"微风","wind2":"微风","wind3":"微风","wind4":"微风","wind5":"微风","wind6":"微风","fx1":"微风","fx2":"微风","fl1":"小于3级","fl2":"小于3级","fl3":"小于3级","fl4":"小于3级","fl5":"小于3级","fl6":"小于3级","index":"热","index_d":"天气较热，建议着短裙、短裤、短套装、T恤等夏季服装。年老体弱者宜着长袖衬衫和单裤。","index48":"暖","index48_d":"较凉爽，建议着长袖衬衫加单裤等春秋过渡装。年老体弱者宜着针织长袖衬衫、马甲和长裤。","index_uv":"弱","index48_uv":"最弱","index_xc":"不宜","index_tr":"适宜","index_co":"较不舒适","st1":"27","st2":"21","st3":"24","st4":"18","st5":"22","st6":"18","index_cl":"较不宜","index_ls":"不太适宜","index_ag":"不易发"}}

我们可以解析json数据去得到自己想用的天气信息。

我想知道大连未来五天的天气，最好是发过来你信息的来源的

之前做过相关的App，网上搜出来的，直接粘贴了。有用请纳哦~

国家气象局提供的天气预报接口

接口地址：

1. XML接口 ://flash.weather.cn/wmaps/xml/china.xml 这个是全国天气的根节点，列出所有的省，其中的pyName字段是各个省XML的文件名，比如北京的是beijing，那就意味着北京的XML地址为 ://flash.weather.cn/wmaps/xml/beijing.xml 一个省的天气，其中列出该省各个市的数据，北京就列出各个区。 tmp1是最低温低，tmp2是最高温度，url非常重要，我们一会儿再说。state1和state2是神马转神马，每个数代表一个天气现象。天气现象非常多，我本想全部分析出来，后来直接放弃了这个想法。因为我看到了一个城市的天气现象的编码是26...我现在知道的有0.晴 1.多云 2.阴 6.雨夹雪 7.小雨 8.中雨 13.阵雪 14.小雪其中后来发现知道这个没用，这个数字的主要作用是检索的！！！

2. 接口 ://m.weather.cn/img/c0.gif ://m.weather.cn/img/b0.gif ://.weather.cn/m/i/weatherpic/29x20/d0.gif ://.weather.cn/m2/i/icon_weather/29x20/n00.gif 这个图就是天气现象0（晴）的，其他天气现象的依此类推。c打头的是20*20像素的，b打头的是50*46像素的，d打头的是反白的图标，29*20像素，n打头的是夜间反白图标，29*20像素，注意这里的文件名是两位数字！也许还有更多的图标，等待大家发掘啦~

3. JSON接口真没想到~居然有JSON接口~JSON在iPhone上分析起来要比XML简单很多 ://m.weather.cn/data/101010200.html 这个是北京的JSON数据，那个HTML的名字是根据上文XML中的url得到的。这个JSON中包含了实时数据、7天天气预报、气象指数等丰富的数据

获取省级代码：://.weather.cn/data/list3/city.xml?level=1获取城市代码(比如安徽是22)：://.weather.cn/data/list3/city22.xml?level=2获取区域代码（比如安庆是2206）：://.weather.cn/data/list3/city2206.xml?level=3获取到安徽省安庆市望江县的代码是220607然后去加上中国代码请求URL：://m.weather.cn/data/101220607.html就可以获取当地天气。

另外再给几个有用的探索得到的URL：天气 FLASH实况：://flash.weather.cn/sk2/101220607.xml实况FLASH：://flash.weather.cn/sk2/shikuang.swf?id=101220607

选择菜单（注明，这里有四个INPUT，其中有一个被隐藏了，可用FIREFOX改下源代码查看）：://.weather.cn/static/custom/search3.htm

实时天气（很有用哦）：://.weather.cn/data/sk/101220607.html

如何使用中国气象局API开发天气APP

15日星期三多云转阵雨高温：12℃低温：6℃南风4-5级转东北风5-6级16日星期四

晴高温：14℃低温：5℃北风5-6级17日星期五

晴高温：16℃低温：7℃西南风4-5级18日星期六

晴高温：17℃低温：8℃南风5-6级19日星期日

多云转中雨高温：20℃低温：13℃微风20日星期一

中雨转晴高温：22℃低温：12℃微风转北风3-4级

前期的准备工作：

一、申请API（拿好id和private_key）

二、解读《SmartWeatherAPI<Lite> WebAPI版接口使用说明书》

三、准备好areaid、type、date、id、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id，和private_key

NSString *id =

@"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“

://writecodeonline/php/ ”下进行算法的检验

echo

urlencode(base64_encode(hash_hmac('sha1', " ://open.weather.cn/data/?areaid=101010100&type=index_f&date=201409041509&id=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*)id {

NSString *Key = [[NSString alloc]

initWithFormat:@"://open.weather.cn/data/?areaid=%@&type=%@&date=%@&id=%@",

areaid, type, [date substringToIndex:12], id];

return

Key;

}

//获得完整的API

- (NSString*) getAPI:(NSString*)areaid

:(NSString*)type :(NSString*)date :(NSString*)id :(NSString*)key

{

NSString *API = [[NSString alloc]

initWithFormat:@"://open.weather.cn/data/?areaid=%@&type=%@&date=%@&id=%@&key=%@",

areaid, type, [date substringToIndex:12], [id substringToIndex:6],

key];

//-------------这里需要主要的是只需要id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 :id] :private_key];

NSString *key =

[getTime

stringByEncodingURLFormat:_key];

最后一步了吧！拼接API

NSString *weatherAPI = [getTime getAPI:areaid :type :date

:id

: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:@"://.weather.cn/data/cityinfo/101010100.html"];

// 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"}}
