Question

我正在尝试遵循此API文档，该文档指出要传递API密钥和json对象，尽管它始终返回错误

它说请求的内容必须是JSON对象，而成分必须是数组。

我不知道即时通讯做错了还是API损坏了。我确实得到了另一个API调用来工作，但营养成分却没有。

curl -d @food.json -H "Content-Type: application/json" "https://api.edamam.com/api/food-database/nutrients?app_id=${YOUR_APP_ID}&app_key=${YOUR_APP_KEY}" 

{
    "yield": 1,
    "ingredients": [
        {
            "quantity": 1,
            "measureURI": "http://www.edamam.com/ontologies/edamam.owl#Measure_unit",
            "foodURI": "http://www.edaman.com/ontologies/edamam.owl#Food_USDABR_45039390"
        }
    ]
}

在我的代码中，这就是我得到的：

let json: [String: Any] = [
                           "ingredients": ["quantity":1,
                                           "measureURI":"http://www.edamam.com/ontologies/edamam.owl#Measure_pound",
                                           "foodURI" : "http://www.edaman.com/ontologies/edamam.owl#Food_USDABR_45039390"]]

let jsonData = try? JSONSerialization.data(withJSONObject: json)

// Nutrition API
let app_id = "51fkkff"
let app_key = "6503a430030768824iidkos03d431d94"


let urlString = String(format: "https://api.edamam.com/api/food-database/nutrients?app_id=%@&app_key=%@", app_id, app_key)
let url = URL(string: urlString)!

var request = URLRequest(url: url)
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")

request.httpBody = jsonData



let task = URLSession.shared.dataTask(with: request) { data, response, error in
    guard let data = data, error == nil else {
        print(error?.localizedDescription ?? "No data")
        return
    }
    let responseJSON = try? JSONSerialization.jsonObject(with: data, options: [])
    if let responseJSON = responseJSON as? [String: Any] {
        print(responseJSON)
    }
}

task.resume()

错误消息：["message": Entity could not be parsed, "error": bad_request]

将其与API文档进行比较时，我看到两个需要修复的错误：

您缺少yield字段。
成分应为数组。

我刚刚使用此JSON对象进行了测试，效果很好：

let json: [String: Any] = [
  "yield": 1,
  "ingredients": [
    [
      "quantity": 1,
      "measureURI": "http://www.edamam.com/ontologies/edamam.owl#Measure_pound",
      "foodURI": "http://www.edamam.com/ontologies/edamam.owl#Food_USDABR_45039390"
    ]
  ]
]

无法解析API，需要转换为JSON对象-错误
