具有数组参数用法的Alamofire 5 POST方法，使用速度为5

Question

我正在使用带有Almofire 5.0.2的Swift 5的iOS项目。我尝试了与此类似的在线线程上建议的所有选项，但看起来我仍然缺少某些内容。

我在进行POST方法API调用时遇到了困难，其中包含一系列作为请求主体的项目。

API看起来像：

@RequestMapping(...)
SomeResponse doSomething (@RequestBody SomeRequest request) {}

[我使用的是Swift 5和Alamo fire 5.0.2版本，我尝试了上面的选项和下面的选项，但是根本没有打API（返回AFError）：

let parameters: [String: Any] = [
            "block": true,
            "items": [],
            "name": "xxxxx",
            "mobile": "xxxxxxxxxx",
            "email": "[email protected]",
            "List": [["place": "london"],["place": "holand"]]

  ]

AF.request(BookingConstants.httpEndpoint, method: .post, parameters: parameters, headers: headers)
            .validate()
            .responseData { response in

}

我在Java Spring Boot API端收到此错误：

Invalid index in property path 'item[][place]'; nested exception is java.lang.NumberFormatException: For input string: ""] with root cause

我知道我丢失了一些东西，但无法弄清楚。有人可以帮我这个忙吗？请让我知道您的意见/建议。在此先感谢

我切换回Alamofire 4.0.1版本，并使用Alamofire上传方法来实现这一目标。

let objectAsJSON: JSON = request.toJSON()
let data: Data = try objectAsJSON.serialize()

Alamofire.upload(data, to: BookingConstants.httpEndpoint, headers: headers)
                .validate()
                .responseData { response in
        // response code logic

}
