I'm trying to retrieve an article from Google news and parse it using Swift. I'm using Alamofire. I know the basics of what to when parsing, but the output seems kind of complex and I don't know how to access the "title" value. Any help would be appreciated. Thanks!
这是JSON输出:
responseData = {
cursor = {
currentPageIndex = 0;
estimatedResultCount = 445755633;
moreResultsUrl = "http://news.google.com/nwshp?oe=utf8&ie=utf8&source=uds&q=sports&hl=en&start=0";
pages = (
{
label = 1;
start = 0;
},
{
label = 2;
start = 1;
},
{
label = 3;
start = 2;
},
{
label = 4;
start = 3;
},
{
label = 5;
start = 4;
},
{
label = 6;
start = 5;
},
{
label = 7;
start = 6;
},
{
label = 8;
start = 7;
}
);
};
results = (
{
GsearchResultClass = GnewsSearch;
clusterUrl = "http://news.google.com/news/story?ncl=dO-ivvqeXteuGKMAkRap55WyAkOvM&hl=en&ned=us";
content = "sportsbook The Third Circuit Court of Appeals will rehear a potentially landmark case Wednesday brought by the NCAA, NFL, MLB, NBA and NHL claiming a New Jersey gambling law enacted in 2014 that repealed certain prohibitions on sports wagering in ...";
image = {
originalContextUrl = "http://lawnewz.com/sports/new-jersey-lawsuit-could-make-sports-betting-legal-across-the-country/";
publisher = LawNewz;
tbHeight = 53;
tbUrl = "http://t0.gstatic.com/images?q=tbn:ANd9GcQ2htg8w11Y6_4ClDD80jdQN6VtGGMya5KomCyLCgzVjOsyMJLVdkffcSg9";
tbWidth = 80;
url = "http://lawnewz.com/wp-content/uploads/2016/02/800px-Las_Vegas_sportsbook-351x234.jpg";
};
language = en;
location = "";
publishedDate = "Tue, 16 Feb 2016 10:47:00 -0800";
publisher = LawNewz;
relatedStories = (
{
language = en;
location = "";
publishedDate = "Tue, 16 Feb 2016 07:34:35 -0800";
publisher = ESPN;
signedRedirectUrl = "http://news.google.com/news/url?sa=T&ct2=us&fd=S&url=http://espn.go.com/chalk/story/_/id/14785562/chalk-previewing-latest-new-jersey-sports-betting-appeal&cid=52779048299261&ei=5OHDVujuMfOmwQHOn53oAg&usg=AFQjCNH7bfL6cWr1Q8PKgPOkQIP7ZRUoRw";
title = "Future of sports betting once again at stake in New Jersey";
titleNoFormatting = "Future of sports betting once again at stake in New Jersey";
unescapedUrl = "http://espn.go.com/chalk/story/_/id/14785562/chalk-previewing-latest-new-jersey-sports-betting-appeal";
url = "http%3A%2F%2Fespn.go.com%2Fchalk%2Fstory%2F_%2Fid%2F14785562%2Fchalk-previewing-latest-new-jersey-sports-betting-appeal";
}
);
signedRedirectUrl = "http://news.google.com/news/url?sa=T&ct2=us&fd=S&url=http://lawnewz.com/sports/new-jersey-lawsuit-could-make-sports-betting-legal-across-the-country/&cid=52779048299261&ei=5OHDVujuMfOmwQHOn53oAg&usg=AFQjCNHAqRF8uPjG1Ki7yxjz0sATv05i6A";
title = "New Jersey Lawsuit Could Make Sports Betting Legal Across the Country";
titleNoFormatting = "New Jersey Lawsuit Could Make Sports Betting Legal Across the Country";
unescapedUrl = "http://lawnewz.com/sports/new-jersey-lawsuit-could-make-sports-betting-legal-across-the-country/";
url = "http%3A%2F%2Flawnewz.com%2Fsports%2Fnew-jersey-lawsuit-could-make-sports-betting-legal-across-the-country%2F";
}
);
};
responseDetails = "";
responseStatus = 200;
}
我对此感到非常困惑，因为它看起来不像我在网上看到的大多数示例.
I'm really confused by this because it doesn't look like most examples I've seen online.
推荐答案
从github添加SwiftyJSON并执行以下操作
add SwiftyJSON from github and do the stuff below
import SwiftyJSON
func parseJson() {
Alamofire.request(.POST, "urlString", parameters: parameter, encoding: .JSON)
.responseJSON { response in
//Check Response
if response.result.isFailure == true {
return
}
let json = JSON(response.result.value!)
let cursorEntity = json["Cursor"]
let currentIndex = json["cursor"].currentPageIndex
let pageEntity = json["cursor"]["pages"]
let resultsEntity = json["cursor"]["results"]
}
}
