使用Swift/SwiftyJSON解析JSON

问题描述

我已经遵循了一些教程，据我所知我应该在做什么.我有来自api调用的以下json响应

I've followed several tutorials on this, and as far as I can tell what I'm doing should be working. I have the following json response from an api call

{
    "Id": "1",
    "Name": "Test User",
    "Email": "[email protected]",
    "ProfileImage": null,
    "IsAdmin": true,
    "TakesJobs": false,
    "IsLocationUser": false,
    "IsCompanyAdmin": true,
    "LocationUsers": [],
    "CompanyUsers": [{
        "CompanyName": "Test Company",
        "Id": 6,
        "CompanyId": 5,
        "UserId": "1",
        "Admin": true,
        "TakesJobs": false,
        "UserName": null,
        "UserEmail": null,
        "AssignedJobs": null
    }]
}

基本上，我只想检查Id值是否为空.这是我正在使用的代码

Essentially I just want to check if the Id value is blank or not. Here is the code I'm using

res返回类型为JSON

The res return type is JSON

ApiConnector.sharedInstance.login(emailText.text!, password: passwordText.text!) { (res) in
    if let id = res["Id"] as? String {
        if id != "" {

        }
        else
        {

        }

    }
}

我得到一条警告，提示从'JSON'转换为不相关的类型'String'总是失败.

I get a warning that says Cast from 'JSON' to unrelated type 'String' always fails.

我需要更改什么才能看到Id的值?

What do I need to change to see the value of Id?

这是ApiConnector类中的代码

This is the code from the ApiConnector class

func login(username: String, password: String, onCompletion: (JSON) -> Void) {
    let route = baseURL + "auth?Email=" + username + "&Password=" + password
    makeHTTPPostRequest(route, body: ["Email":username, "Password": password], onCompletion: { json, err in
        onCompletion(json as JSON)
        })
}

推荐答案

我认为您想要这样的东西:

I think you want something like this:

ApiConnector.sharedInstance.login(emailText.text!, password: passwordText.text!) { (res) in
    if let id = res["Id"].string {
      // Do something.
    }
}
