我已经有一段时间了,但无法正确解析。我正在尝试解析此 json 文件:
{
"order_history" : [ {
"items" : [ {
"id" : 284,
"created" : [ 2016, 5, 26, 5, 27, 53 ],

"discount" : null
}, {
"id" : 285,
"created" : [ 2016, 5, 26, 5, 27, 53 ],
"updated" : [ 2016, 5, 27, 0, 31, 10 ],

"items" : [ {

} ]
}
]
}
就像现在一样,我能从中得到的只是第一套产品。我想做的是获取所有三个集合以及"创建"字段。我根本没有运气得到创建的字段。它只是空的。
这就是我从 json 文件中获取数据的方式
for (_, myosin) in newJson["order_history"][0]["items"] {
if let set = myosin["name"].string {
//products is a string crated somewhere up there ^
products.appendContentsOf("n" + name)
}
}
感谢您对此的任何帮助。
您正在将"name"字段解码为set
变量,但随后您尝试使用不存在的name
变量。您也在使用appendContentsOf
但它应该是append
的。
var products = [String]()
for (_, myosin) in newJson["order_history"][0]["items"] {
if let set = myosin["name"].string {
products.append("n" + set)
}
}
print(products)
要获取每个字典的"创建"数组:
var createdArrays = [[Int]]()
for (_, myosin) in newJson["order_history"][0]["items"] {
if let created = myosin["created"].arrayObject as? [Int] {
createdArrays.append(created)
}
}
print(createdArrays)
