用于ecobee请求的Alamofire语法 [英] Alamofire syntax for ecobee request

问题描述

我试图找到使用Alamofire从Swift 4调用ecobee的API的正确语法。

I'm trying to find the correct syntax for calling ecobee's API from Swift 4 using Alamofire.

他们的cURL示例：

curl -H "Content-Type: text/json" -H "Authorization: Bearer ACCESS_TOKEN" 'https://api.ecobee.com/1/thermostat?format=json&body=\{"selection":\{"selectionType":"registered","selectionMatch":"","includeRuntime":true\}\}'

我最接近解决方案的是这个

The closest I've been to a solution is this

func doRequest() {
    guard let url = URL(string: "https://api.ecobee.com/1/thermostat?format=json") else { return }

    let parameters: Parameters = [
        "selection": [
            "selectionType": "registered",
            "selectionMatch": ""
        ]
    ]

    let headers: HTTPHeaders = [
        "Content-Type": "text/json",
        "Authorization": "Bearer \(core.accessToken)"
    ]

    let req = AF.request(url, method: .get, parameters: parameters, encoding: JSONEncoding.default, headers: headers)
        .responseJSON { response in
            print("Error:", response.error?.localizedDescription ?? "no error")
            print("Data:", String(data: response.data!, encoding: .utf8)!)
    }

    debugPrint(req)
}

运行此命令时，呼叫最终失败，状态码为408，服务器超时

When I run this, the call ultimately fails with status code 408, a server timeout.

当我将HTTP方法更改为使用.post时，调用完成，但响应为内部状态3，消息为由于通信错误，更新失败。

When I change the HTTP method to use .post, the call completes, but the response is an internal status 3 with message "Update failed due to a communication error."

有人能帮我弄清楚我在做错什么，然后再浪费第二天试图破解它吗？

Can anyone help me figure out what I'm doing wrong before I waste another day trying to hack my way through it?

推荐答案

Ecobee的请求格式有些奇怪，因为它使用了表单编码的参数，但是其中一个值是JSON编码的主体。您需要做一些准备工作，因为Alamofire并不自然支持这种功能。这只是示例代码，您需要做一些工作以使其更安全。

Ecobee's request format is a bit bizarre, as it uses form encoded parameters, but one of the values is a JSON encoded body. You'll have to do a little bit of prep work, as Alamofire doesn't naturally support something like this. This is just sample code, you'll need to do the work to make it safer.

首先，对JSON参数进行编码并获取 String 值：

First, encode the JSON parameters and get the String value:

let jsonParameters = ["selection": ["selectionType": "registered", "selectionMatch": ""]]
let jsonData = try! JSONEncoder().encode(jsonParameters)
let jsonString = String(decoding: jsonData, as: UTF8.self)

然后，创建实际的参数和标头值：

Then, create the actual parameters and headers values:

let parameters = ["format": "json", "body": jsonString]
let token = "token"
let headers: HTTPHeaders = [.authorization(bearerToken: token), .contentType("text/json")]
let url = URL(string: "https://api.ecobee.com/1/thermostat")!

并发出请求：

AF.request(url, parameters: parameters, headers: headers).responseJSON { response in ... }
