Question

我尝试将服务器的响应设为bool而不是{ "name": "Application Settings", "description": "Common application settings.", "visible": true, "groups": [ { "name": "General settings", "description": null, "visible": true, "groups": [ { "name": "Startup settings", "description": null, "visible": true, "groups": [], "settings": [ { "name": "Start IM with Windows", "description": null, "visible": true, "descriptionVisibility": 0, "configuration": {}, "settingValue": true, "settingType": 0, "settingControl": 0 }, { "name": "Start IM minimized", "description": null, "visible": true, "descriptionVisibility": 0, "configuration": {}, "settingValue": true, "settingType": 0, "settingControl": 0 } ] }, { "name": "Performance settings", "description": null, "visible": true, "groups": [], "settings": [ { "name": "Thread priority", "description": "This setting may not have a noticeible impact on all platforms, especially higer end ones.", "visible": true, "descriptionVisibility": 0, "configuration": { "lowVal": 0, "highVal": 7, "interval": 1 }, "settingValue": 3, "settingType": 0, "settingControl": 2 } ] } ], "settings": [] }, { "name": "Theme settings", "description": null, "visible": true, "groups": [], "settings": [] }, { "name": "Update settings", "description": null, "visible": true, "groups": [], "settings": [] }, { "name": "General settings", "description": null, "visible": true, "groups": [ { "name": "Startup settings", "description": null, "visible": true, "groups": [], "settings": [ { "name": "Start IM with Windows", "description": null, "visible": true, "descriptionVisibility": 0, "configuration": {}, "settingValue": true, "settingType": 0, "settingControl": 0 }, { "name": "Start IM minimized", "description": null, "visible": true, "descriptionVisibility": 0, "configuration": {}, "settingValue": true, "settingType": 0, "settingControl": 0 } ] }, { "name": "Performance settings", "description": null, "visible": true, "groups": [], "settings": [ { "name": "Thread priority", "description": null, "visible": true, "descriptionVisibility": 0, "configuration": {}, "settingValue": 3, "settingType": 0, "settingControl": 0 } ] } ], "settings": [] }, { "name": "Theme settings", "description": null, "visible": true, "groups": [], "settings": [] }, { "name": "Update settings", "description": null, "visible": true, "groups": [], "settings": [] } ], "settings": [] }，因此首先我使用AFNetworking库并且服务器请求这些设置为HTTP而不是NSDictionary序列化程序如下：

NSData

接下来是当我从服务器获得响应时，它变为JSON，因为我使用self.responseSerializer = AFHTTPResponseSerializer() as AFHTTPResponseSerializer self.requestSerializer = AFHTTPRequestSerializer() as AFHTTPRequestSerializer self.requestSerializer.HTTPMethodsEncodingParametersInURI = NSSet(array: ["GET"]) as! Set<String> self.responseSerializer.acceptableContentTypes = NSSet(objects: "application/json","text/json","text/javascript","text/html") as? Set<String>，这是我的代码：

NSData

同样在AFNetworking块中，不允许处理AFHTTPRequestSerializer()的try和catch，这可能是一种可能的解决方案，但它不起作用。

Answer 1

使用NSJSONSerialization，如下面的代码所示：

do {
    let jsonObject = try NSJSONSerialization.JSONObjectWithData(responseObject, options: .AllowFragments) as! NSDictionary
    // use jsonObject here
} catch {
    print("json error: \(error)")
}

Answer 2

由于您从服务器获得的响应没有Array或Dictionary的顶级对象，您必须指定自定义阅读选项， AFNetworking < / em>的。

为此，您必须在responseSerializer类的实例上设置AFURLSessionManager属性。你可以这样做：

let sessionManager = OLFURLSessionManager.init() //you probably want to keep session manager as a singleton sessionManager.responseSerializer = AFJSONResponseSerializer.serializerWithReadingOptions(.AllowFragments) //you should use that instance of session manager to create you data tasks

之后，您应该能够正确解析来自服务器的响应，如下所示：

接收响应为NSDictionary而不是NSData
