我如何解析一个JSON,它在一个JSON对象中包含一个数组,而没有arrayName[closed]

你可能需要检查一下 SwiftyJSON 但这是你使用Foundation的答案。

Swift 4:

let str = """
[
{
"accNo":"8567856",
"ifscCode":"YESB000001"
},
{
"accNo":"85678556786",
"ifscCode":"YESB000001"
}
]
"""

let data = str.data(using: .utf8)!

do {

    let json = try JSONSerialization.jsonObject(with: data) as? [[String:String]]

    for item in json! {

        if let accNo = item["accNo"] {
            print(accNo)
        }

        if let ifscCode = item["ifscCode"] {
            print(ifscCode)
        }
    }

} catch {
    print("Error deserializing JSON: \(error)")
}

使用 JSONSerialization 要将数据转换为字符串字典数组, [[String:String]] .

let str = """
[
{
"accNo":"8567856",
"ifscCode":"YESB000001"
},
{
"accNo":"85678556786",
"ifscCode":"YESB000001"
}
]
"""
let data = str.data(using: .utf8)!
let json = try JSONSerialization.jsonObject(with: data, options: JSONSerialization.ReadingOptions.allowFragments) as! [[String:String]]
print(json) // [["accNo": "8567856", "ifscCode": "YESB000001"], ["accNo": "85678556786", "ifscCode": "YESB000001"]]
