Question

我有一个NodeJS API，用于查询MongoDB集群并以下列格式返回附近的数据。问题是我无法使用Swift 3和XCode 8.1枚举位置。

[ { ＆＃34; _id＆＃34;：＆＃34; 57b03fa32c6835946afd358c＆＃34;，＆＃34; location＆＃34;：{ ＆＃34;坐标＆＃34;：[ 144.2， -34 ] ＆＃34;海拔＆＃34;：＆＃34; 1＆＃34;，＆＃34;输入＆＃34;：＆＃34;点＆＃34; }，＆＃34; name＆＃34;：＆＃34;资源01＆＃34;，＆＃34; url＆＃34;：＆＃34; http://www.url.com/Resource01.html＆＃34; }， { ＆＃34; _id＆＃34;：＆＃34; 34b03fa32c6835946afd358c＆＃34;，＆＃34; location＆＃34;：{ ＆＃34;坐标＆＃34;：[ 154.2， -35.3 ] ＆＃34;海拔＆＃34;：＆＃34; 1＆＃34;，＆＃34;输入＆＃34;：＆＃34;点＆＃34; }，＆＃34;名称＆＃34;：＆＃34;资源02＆＃34;，＆＃34; url＆＃34;：＆＃34; http://www.url.com/Resource02.html＆＃34; } ]

这是我的查询代码。

let json = try! JSONSerialization.jsonObject(with: data)

print(json)

if let statusesArray = try? JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [[String: AnyObject]],
    let jsonbranch = statusesArray?[0] as? [String: AnyObject],
    let therecord = jsonbranch["_id"] as? String {
    print ("_id: " + therecord)
}

我尝试使用SwiftyJSON，但它也不起作用？

解决：

if let jsonBranch = try? JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [[String: AnyObject]],
    let name = jsonBranch?[0]["name"] as? String {
    print ("name: " + name)
}
if let jsonBranch = try? JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [[String: AnyObject]],
    let name = jsonBranch?[1]["name"] as? String {
    print ("name: " + name)
}

在Xcode 8.1 Swift 3中从MongDB读取GeoJSON数据？
