从Swift到PHP的字典 [英] Post dictionary from Swift to PHP

问题描述

具体来说，任务是更新托管数据库上的许多字段。而不是将每个字段的新值定义为单独的参数，我希望通过一个字典，其中键是字段名称，值是新值。这个数据已经以Swift的 Dictionary< String，String> 的形式存在，如何以下列格式将其粘贴到php网址：

 http：//server/directory/targetScript.php/？recordId = \（recId）& newFieldArray = \（itemDict）
  

其中：

recId =正在更新的记录ID（作为与字典一起传递单独变量的示例）

itemDict = Swift中生成的字典

以下是当前代码 ...返回一个错误，显示 url 为nil

  class func updateItemInfo（recordId：String，updatedDict：Dictionary< String，String>） - > Void {
 // recordId =要更新的项目的FileMaker recordId 
 // updatedDict =当前项的primaryKey 
 
 //直接到php文件位置
 let server：String =myServer.com
 let phpFile：String =/php/UpdateRecord.php
 
 let baseURL = NSURL（string：http：// \ （server）\（phpFile））
 let url = NSURL（string：？recordId = \（recordId）& newData = \（updatedDict），relativeToURL：baseURL）
 let cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData 
 var request = NSMutableURLRequest（URL：url !, cachePolicy：cachePolicy，timeoutInterval：20.0）
 request.HTTPMethod =POST
 
 //设置数据
 var dataString =
 let requestBodyData =（dataString as NSString）.dataUsingEncoding（NSUTF8StringEncoding）
 request.HTTPBody = requestBodyData 
 
 var response：NSURLResponse？ = nil 
 var error：NSError？ = nil 
让回复：NSData！ = NSURLConnection.sendSynchronousRequest（request，returnsResponse：& response，error：& error）
 let result = NSString（data：reply !, encoding：NSUTF8StringEncoding）
 println（results）
} 
  

解决方案

为什么不使用JSON传递值。

1. 转换字典到JSON字符串。


2. 如果您以查询字符串的形式发送此数据;您必须对其进行URL编码


3. 最后你可以发送给PHP;它将作为$ _GET中的单个参数达到。
   您将需要PHP的 json_decode 来获取关联的数组从

How can a dictionary generated in Swift be posted as parameter in a PHP URL?

Specifically, the task is to update many fields on a hosted database. Rather than define new values for each field as a separate parameter, I am looking to pass a dictionary where the keys are the field names and the values are the new values. This data already exists as a Dictionary<String, String> in Swift - how can it be tacked on to the php url in the following format:

"http://server/directory/targetScript.php/?recordId=\(recId)&newFieldArray=\(itemDict)"

Where:

recId = the record id that is being updated (as an example of passing a separate variable along with the dictionary)

itemDict= the dictionary generated in Swift

Here is the current code: ... which returns an error showing url as "nil"

class func updateItemInfo ( recordId:String, updatedDict:Dictionary<String, String> ) -> Void {
    //recordId = the FileMaker recordId of the item being updated
    //updatedDict = the primaryKey of the current item

    //direct to php file location
    let server:String = "myServer.com"
    let phpFile:String = "/php/UpdateRecord.php"

    let baseURL = NSURL(string: "http://\(server)\(phpFile)")
    let url = NSURL(string: "?recordId=\(recordId)&newData=\(updatedDict)", relativeToURL: baseURL)
    let cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData
    var request = NSMutableURLRequest(URL: url!, cachePolicy: cachePolicy, timeoutInterval: 20.0)
    request.HTTPMethod = "POST"

    // set data
    var dataString = ""
    let requestBodyData = (dataString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
    request.HTTPBody = requestBodyData

    var response: NSURLResponse? = nil
    var error: NSError? = nil
    let reply: NSData! = NSURLConnection.sendSynchronousRequest(request, returningResponse:&response, error:&error)
    let results = NSString(data:reply!, encoding:NSUTF8StringEncoding)
    println(results)
}

解决方案

Why don't you use JSON to pass the values.

1. Convert the Dictionary to JSON String.
2. If you are sending this data as a query string; you will have to URL encode it
3. Finally you can send it to PHP; where it will reach as a single parameter in $_GET. There you will need PHP's json_decode to get an associated array back from it.
