Question

我需要将请求正文看起来像这样：

{
  "accepted" : [
    {
      "deposit" : 2000,
      "name" : "Tuxedo",
      "rent" : 100,
      "id" : 3,
      "favourited_by" : [

      ],
      "tag_id" : 21,
      "status" : "unknown",
      "image_url" : "https:\/\/www.moss.co.uk\/images\/extralarge\/965549415_01.jpg",
      "addresses" : [

      ]
    },
    {
      "deposit" : 3000,
      "name" : "ps4",
      "rent" : 50,
      "id" : 2,
      "favourited_by" : [

      ],
      "tag_id" : 16,
      "status" : "unknown",
      "image_url" : "http:\/\/www.spokeslabs.com\/jstone\/ps4_images\/ps4-hrdware-large18.jpg",
      "addresses" : [

      ]
    },
    {
      "deposit" : 1000,
      "name" : "Electric drill",
      "rent" : 100,
      "id" : 1,
      "favourited_by" : [

      ],
      "tag_id" : 11,
      "status" : "unknown",
      "image_url" : "https:\/\/static.independent.co.uk\/s3fs-public\/styles\/story_medium\/public\/thumbnails\/image\/2016\/06\/20\/12\/ryobi-rpd800-k-percussion-d.jpg",
      "addresses" : [

      ]
    }
  ],
  "rejected" : [

  ],
  "address" : 
    {
      "city" : "Hong Kong",
      "lng" : "114.162699999745",
      "country" : "Hong Kong",
      "street" : "Barker Road",
      "id" : "0",
      "label" : "Home",
      "lat" : "22.269837686727"
    }
}

不幸的是，我发送了这个：

{
  "accepted" : [
    {
      "deposit" : 2000,
      "name" : "Tuxedo",
      "rent" : 100,
      "id" : 3,
      "favourited_by" : [

      ],
      "tag_id" : 21,
      "status" : "unknown",
      "image_url" : "https:\/\/www.moss.co.uk\/images\/extralarge\/965549415_01.jpg",
      "addresses" : [

      ]
    },
    {
      "deposit" : 3000,
      "name" : "ps4",
      "rent" : 50,
      "id" : 2,
      "favourited_by" : [

      ],
      "tag_id" : 16,
      "status" : "unknown",
      "image_url" : "http:\/\/www.spokeslabs.com\/jstone\/ps4_images\/ps4-hrdware-large18.jpg",
      "addresses" : [

      ]
    },
    {
      "deposit" : 1000,
      "name" : "Electric drill",
      "rent" : 100,
      "id" : 1,
      "favourited_by" : [

      ],
      "tag_id" : 11,
      "status" : "unknown",
      "image_url" : "https:\/\/static.independent.co.uk\/s3fs-public\/styles\/story_medium\/public\/thumbnails\/image\/2016\/06\/20\/12\/ryobi-rpd800-k-percussion-d.jpg",
      "addresses" : [

      ]
    }
  ],
  "rejected" : [

  ],
  "address" : [
    {
      "city" : "Hong Kong",
      "lng" : "114.162699999745",
      "country" : "Hong Kong",
      "street" : "Barker Road",
      "id" : "0",
      "label" : "Home",
      "lat" : "22.269837686727"
    }
  ]
}

区别在于JSON的最后一部分。我发送的内容包含一个地址数组，但我想发送只包含一个地址对象。

此请求正文以下列方式创建：

    var parameters = [String:[AnyObject]]()
    parameters["rejected"] = rejectedItemsArray as [AnyObject]
    parameters["accepted"] = acceptedItemsArray as [AnyObject]
    parameters["address"] = addressArray as [AnyObject]

    let request = NSMutableURLRequest(URL: NSURL(string: urlString)!)
    request.setValue(self.token!, forHTTPHeaderField: Constant.tokenUserDefaultsKey)
    request.HTTPMethod = "POST"
    do {
        let data = try NSJSONSerialization.dataWithJSONObject(parameters, options: .PrettyPrinted)
        let requestBodyString = String(data: data, encoding: NSUTF8StringEncoding)
        NSLog("Request Body: %@", requestBodyString!)
        request.HTTPBody = data
    } catch ( _) {
        NSLog("Failed to encode json for Post Items")
    }

我该如何解决？

我希望在我的JSON中有2个数组：

1 - ＆＃34;接受＆＃34; 2 - ＆＃34;拒绝＆＃34;

我的JSON中有一个单个对象：

1 - ＆＃34;地址＆＃34;

Answer 1

问题出在这一行parameters["address"] = addressArray as [AnyObject]。您正在使用Array键设置address，而不是需要设置字典。所以像这样创建addressDic。

let adddressDic = ["city" : "Hong Kong",  "lng" : "114.162699999745", "country" : "Hong Kong", 
                   "street" : "Barker Road", "id" : "0", "label" : "Home", "lat" : "22.269837686727"]

现在使用Dictionary键

设置此address

parameters["address"] = adddressDic

编辑：您还需要更改此类参数的声明。

var parameters = [String:AnyObject]()

Answer 2

parameters["address"] = addressArray as [Any]

这里（在这行代码中）您正在分配数组实例。创建'addressArray'的JSON对象（Dictionary），然后将其分配给参数[“address”]
e.g。

var addresArray = [String : Any]()

//在其中存储json值/信息，然后

parameters["address"] = addressArray as [String : Any]

为Alamofire创建请求主体
