本文通过Swift和Objective-C代码示例介绍了如何使用同步HTTP请求获取天气API数据，并将其解析为可读格式。演示了从指定URL获取数据的具体步骤，包括创建请求、发送请求并解析返回的JSON数据。

SynchonousRequest:

let urlPath: String = "http://www.weather.com.cn/data/sk/101010100.html"

var url: NSURL = NSURL(string: urlPath)!

var request1: NSURLRequest = NSURLRequest(URL: url)

var response: AutoreleasingUnsafeMutablePointer<NSURLResponse? >= nil

var error: NSErrorPointer = nil

var dataVal: NSData = NSURLConnection.sendSynchronousRequest(request1, returningResponse: response, error:nil)!

var err: NSError

var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(dataVal, options: NSJSONReadingOptions.MutableContainers, error: nil) as! NSDictionary

println("Synchronous \(jsonResult)")

Log:

Synchronous {

weatherinfo = {

Radar = "JC_RADAR_AZ9010_JB";

SD = "26%";

WD = "\U4e1c\U5357\U98ce";

WS = "2\U7ea7";

WSE = 2;

city = "\U5317\U4eac";

cityid = 101010100;

isRadar = 1;

njd = "\U6682\U65e0\U5b9e\U51b5";

qy = 1012;

temp = 10;

time = "10:25";

};

}

// 1.设置请求路径

NSString *urlStr=[NSString stringWithFormat:@"http://www.weather.com.cn/data/sk/101010100.html"];

NSURL *url=[NSURL URLWithString:urlStr];

// 2.创建请求对象

NSURLRequest *request=[NSURLRequest requestWithURL:url];

NSData *received = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

NSString *str = [[NSString alloc]initWithData:received encoding:NSUTF8StringEncoding];

NSLog(@"%@",str);

Log:

{"weatherinfo":{"city":"北京","cityid":"101010100","temp":"10","WD":"东南风","WS":"2级","SD":"26%","WSE":"2","time":"10:25","isRadar":"1","Radar":"JC_RADAR_AZ9010_JB","njd":"暂无实况","qy":"1012"}}
