问题描述
我整天都在寻找答案，我快要崩溃了并且哭泣，但是任何人都可以向我展示或指出我如何解析此JSON文件，以便可以访问第一个JSON文件.数组成员"并打印出所有成员的名字?我现在查看的所有信息都无法在Swift 3(!!!)中使用.
I have been searching for an answer to this all day and I'm about to break down and cry but can anyone show me or point me in the direction of how I would parse this JSON file so that I could access the first array of 'members' and print out the first name of all of them? All of the info I looked at now doesn't work in Swift 3(!!!).
JSON文件:
[
{
"id" : "001",
"firstName" : "Mark",
"lastName" : "Mason",
"role" : "CEO",
"profileImageURL" : "http://developers.mub.lu/resources/profilePlaceholder.png"

我一直收到错误消息类型'Any'没有下标成员"，我只是不知道该怎么办.我这样解析数据:
I keep getting the error 'Type 'Any' has no subscript members' and I just don't know what to do anymore. I parsed the data like this:
let urlString = "url of the json file"
let url = URL(string: urlString)
URLSession.shared.dataTask(with:url!, completionHandler: {(data, response, error) in
if error != nil {
print(error)
} else {
do {
let parsedData = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as! NSMutableArray
} catch let error as NSError {
print(error)
}
}
}).resume()
但是我不知道如何访问各个数组和字典.
but then I have no idea how to access the individual arrays and dictionaries.
谢谢！
推荐答案
因为您的数组包含格式不同的项目.第一项包含CEO信息，其余项包含团队信息.
Because your array contain items not in same format. The first item contain CEO info, an rest items contain teams info.
您可以通过检查当前项目是CEO还是团队来解析它们
You can parse them by check current items is CEO or teams
这是您在 Swift3
do {
if let parsedData = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as? [[String: AnyObject]] {
// parse data here
for item in parsedData {
if let ceoFirstName = item["firstName"] as? String { // first item is CEO info. You can get more info like id, lastName, role, profileImageURL here
print("CEO firstName is \(ceoFirstName)")
}
if let teamName = item["teamName"], members = item["members"] as? [[String: AnyObject]] { // rest items are teams
print("all members firstName from team \(teamName):")
for member in members { // loop for all members
if let firstName = member["firstName"] as? String {
print("firstName = \(firstName)")
}
// you can get other member info like id, lastName, role, profileImageURL, teamLead here
}
}
}
}
} catch {
print(exception)
}
结果:
CEO firstName is Mark
all members firstName from team iOS:
firstName = Olly
firstName = James
firstName = Liam
firstName = Chris
firstName = Richard
firstName = Matt
firstName = David
firstName = Tom
firstName = Rich
all members firstName from team Android:
firstName = David
firstName = Dre
firstName = Ray
firstName = Charly
all members firstName from team Web:
firstName = Ryan
firstName = James
firstName = Adam
firstName = Leonard
all members firstName from team Design:
firstName = Hannah
firstName = Ellis
firstName = Pete
firstName = Hemel
firstName = Hannah
