我想一個POST體發送到使用的iOS（SWIFT）由AWS API網關產生SDK一個AWS LAMBDA功能，但發送的身體總是空的。API網關：空請求正文？
爲此我成立了一個模型：
{
"$schema": "http://json-schema.org/draft-04/schema#",
"title": "InputModel",
"type": "object",
"required" : ["name"],
"properties": {
"name": { "type": "string" },
}
}
，我包括在$資源 - > /測試 - > POST - >方法執行 - >方法請求 - >請求體面板。
然後我部署了API並下載幷包含了API網關生成的SDK。現在我調用API（如Use Generated iOS SDK (Swift) to Call API推薦），像這樣：
let apiClient = APITestClient.default()
let body = APITest()
body!.name = "HOLA"
apiClient.testPost(body: body!).continueWith { task -> Void in ... }
但體我lambda函數接收總是空{}，這是我在API網關日誌檢查：
(c421a895-b0c7-11e7-89a6-891dcbadf1f0) Method request body before transformations:
{}
和lambda函數日誌：

爲什麼身體總是空的？我是否需要初始化與我不同的身體？還是有另一個階段，身體被清除？
編輯： 我還在掙扎，但是調用正常AWS iOS版SDK：
let apiClient = APITestClient.default()
let apiGatewayRequest = AWSAPIGatewayRequest(httpMethod: "POST", urlString: "/test", queryParameters: nil, headerParameters: nil, httpBody: ["name":"example"])
apiClient.invoke(apiGatewayRequest).continueWith { task -> Void in ... }
工作完全正常。爲什麼AWS甚至不打算生成一個特殊的API網關SDK？
編輯2：API模型
public class APITest : AWSModel {
var example: String?
public override static func jsonKeyPathsByPropertyKey() -> [AnyHashable : Any]!{
var params:[AnyHashable : Any] = [:]
params["name"] = "name"
return params
}
}
然後由
public func testPost() -> AWSTask<APITest> {
let headerParameters = [
"Content-Type": "application/json",
"Accept": "application/json",
]
let queryParameters:[String:Any] = [:]
let pathParameters:[String:Any] = [:]
return self.invokeHTTPRequest("POST", urlString: "/test", pathParameters: pathParameters, queryParameters: queryParameters, headerParameters: headerParameters, body: nil, responseClass: APITest.self) as! AWSTask<APITest>
}
你可以嘗試從API網關集成請求的響應模擬？ –
我試過了，但是身體還是空的。是否生成的SDK與XCode 9.0中的Swift 4不兼容？ – Knowledge
您可以使用Postman或其他HTTP客戶端測試您的API端點嗎？ – dashmug
