如何在Swift中解析特定的JSON
如何在Swift中解析特定的JSON
提问于 2018-10-23 00:45:12
为了解析JSON，正如我在web上发现的那样，我通常使用这种代码：
guard let results = receivedUserJSON["results"] as? [String: Any] else {
print("Error interpreting results")
return
}这一次我有一个问题，因为它似乎结束在这个守卫的其他let。JSON的结构如下：
{
"results": [{
"gender": "female",
"name": {
"title": "mrs",
"first": "silene",
"last": "almeida"
},
"location": {
"street": "2594 rua maranhão ",
"city": "pouso alegre",
"state": "distrito federal",
"postcode": 20447,
"coordinates": {
"latitude": "-70.0198",
"longitude": "123.6577"
},
"timezone": {
"offset": "+4:30",
"description": "Kabul"
}
},
"email": "silene.almeida@example.com",
"login": {
"uuid": "d06a46b3-1c00-42be-b8fc-d271bf901f7d",
"username": "silversnake251",
"password": "ventura",
"salt": "UcckU6RG",
"md5": "7c8c4129587c61da01ca7cf4f88353c5",
"sha1": "6cbf7ec377ff4ebad5a392ec487343bf613858ef",
"sha256": "8dedf3649fb833a1936b8885627b86c6cf02062eb74f727b2cbd674a30f73e75"
},
"dob": {
"date": "1969-07-13T00:58:26Z",
"age": 49
},
"registered": {
"date": "2003-09-28T09:44:56Z",
"age": 15
},
"phone": "(95) 0094-8716",
"cell": "(20) 1014-3529",
"id": {
"name": "",
"value": null
},
"picture": {
"large": "https://randomuser.me/api/portraits/women/66.jpg",
"medium": "https://randomuser.me/api/portraits/med/women/66.jpg",
"thumbnail": "https://randomuser.me/api/portraits/thumb/women/66.jpg"
},
"nat": "BR"
}],
"info": {
"seed": "dd971cddf636d2d7",
"results": 1,
"page": 1,
"version": "1.2"
}
}我应该怎么做才能正确地解析这个JSON？我不喜欢使用可编码的解决方案，因为我不需要所有这些值。
PS:我知道json是正确的，因为我尝试并打印了它：
if let JSONString = String(data: responseData, encoding: String.Encoding.utf8) {
print(JSONString)

results是一个数组
guard let results = receivedUserJSON["results"] as? [[String:Any]] else {
print("Error interpreting results")
return
}我没有看到它是一个数组的值，因为它包含1个元素，所以你可以考虑修改这个json
当前结构
{
"results": [{}],
"info": {
"seed": "dd971cddf636d2d7",
"results": 1,
"page": 1,
"version": "1.2"
}
}您可以将其更改为
{
"results": {},
"info": {
"seed": "dd971cddf636d2d7",
"results": 1,
"page": 1,
"version": "1.2"
}
