需要帮助从PHP的混合源中为Swift准备JSON

  • json
  • php
  • arrays
  • xcode
  • swift

I will try to be as thorough as possible with this question.

To start, I have the following struct defined in my code:

struct LogInfo {
    var logNumber: Int
    var species: String
    var diameter: Float
    var formClass: Int
    var numLogs: Float
    var boardFootage: Double

    static func jsonArray(array : [LogInfo]) -> String {
        return "[" + array.map {$0.jsonRepresentation}.joinWithSeparator(",") + "]"
    }

    var jsonRepresentation : String {
        return "{\"logNumber\":\"\(logNumber)\",\"species\":\"\(species)\",\"diameter\":\"\(diameter)\",\"formClass\":\"\(formClass)\",\"numLogs\":\"\(boardFootage)\"}"
    }
}

This basically creates a JSON representation of the defined struct.

In another part of my code, I am composing a JSON string with the following:

let sessionConfig = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration: sessionConfig, delegate: nil, delegateQueue: nil)

guard let URL = NSURL(string: "http://logster.dynamiscms.com/jsonTest.php") else {return}

let request = NSMutableURLRequest(URL: URL) 
request.HTTPMethod = "POST"

// Headers
request.addValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")


//Get the JSON Array from the Struct
let jsonArray = LogInfo.jsonArray(logArray)


// Compose the JSON Body
let bodyObject = [
    "propertyOwner": "\(propertyOwner)",
    "propertyID": "\(propertyID)",
    "scaledBy": "\(scaledBy)",
    "acres": "\(acres)",
    "notes": "\(notes)",
    "logDetails": jsonArray
]

Everything up to this point basically takes 5 variables that were passed into my segue, and then appends the JSON that was prepared in the struct.

I want to pass that JSON that I compiled to a PHP script, which will then parse that JSON and eventually store it into a database.

I am not getting any errors in my code - but the JSON is not being prepared properly, which is causing me to be unable to parse through it in PHP.

Based on this code, I AM able to parse the first five values (propertyOwner, propertyID, scaledBy, acres and notes) with PHP. However, when I get into the array of details, I cannot get into those nested values.

It looks like when I pass it into my PHP script, it is spitting out this as the JSON (which I realize is not valid JSON):

[
    "notes": "This is a test.",
    "propertyID": "Beam Residence",
    "acres": "1",
    "scaledBy": "Andy Spencer",
    "propertyOwner": "Jim Beam",
    "logDetails": "
        {\"logNumber\":\"1\",\"species\":\"White Pine\",\"diameter\":\"18.0\",\"formClass\":\"78\",\"numLogs\":\"124.56227\"},

        {\"logNumber\":\"2\",\"species\":\"Hemlock\",\"diameter\":\"17.0\",\"formClass\":\"78\",\"numLogs\":\"147.0589725\"},

        {\"logNumber\":\"3\",\"species\":\"Spruce\",\"diameter\":\"21.0\",\"formClass\":\"82\",\"numLogs\":\"335.9106016\"}"

]

Is anybody able to help me make sense of what I am missing?
