使用swift提取数据4

我试图从swift提取数据4，我的响应为零。使用swift提取数据4

class JobSeekerJsonRequests: NSObject{ 

class func jobSeekerRequest(completion: @escaping(_ error: Error?, _ jobSeekerData : JobSeekerDataAPI?) ->Void) { 

    let jsonURLString = URLs.jobSeeker 

    guard let url = URL(string: jsonURLString) else { return } 

    URLSession.shared.dataTask(with: url) { (data, response, error) in 

     guard let data = data else { return } 

     do { 
      let jobSeekerData = try 
       JSONDecoder().decode(JobSeekerDataAPI.self, from: data) 
      print(jobSeekerData) 

     }catch let jsonError { 
      print("Error serializing json: ", jsonError) 
     } 

    }.resume() 
}

然后：

func userData(){ 

    JobSeekerJsonRequests.jobSeekerRequest { (error: Error?, jobSeekerData: JobSeekerDataAPI?) in 

     if let jobSeekerData = jobSeekerData { 

      self.myProfileJobTitle.text = jobSeekerData.most_recent_work_history?.position 
      self.menuProfileName.text = jobSeekerData.job_seeker_name 
      self.userNameLabel.text = jobSeekerData.first_name 
      self.userNameJobPositionLabel.text = jobSeekerData.most_recent_work_history?.position 
      self.userLocationLabel.text = jobSeekerData.location_country?.location_country_name 
      self.infoAboutLabel.text = jobSeekerData.about 
      self.userJobTitleLabel.text = jobSeekerData.most_recent_work_history?.position 

     } 
    }

我有一些问题了解API请求监守我一直工作在这我没有从中得到任何答案。我在过去的5个月里很快就学会了自己，我在这个问题上停滞不前。对不起，如果它看起来像一个愚蠢的问题，但它是如何新的家伙喜欢我卡住，需要帮助。

谢谢你们！

啊。评论是因为我试图手动阅读。 – Khromos

解决问题之前尝试输入较少的代码或5个月将是5年，你仍然坚持 – zombie

您使用CodingKeys enum的方式是不正确的。

正如苹果文档说：

的枚举案件的名称应与你在你的类型给出到相应属性的名称。

如果您的序列化的数据格式使用不从你的数据类型相匹配的属性名，由指定字符串作为原始值类型为CodingKeys 枚举提供替代键的键。您用作每个枚举大小写的原始值的字符串是编码和解码过程中使用的密钥名称。

简而言之：

情况名是完全一样的属性名
rawValue一个具体案件的是要使用自定义键名称 。

你正在做的事情与需要完成的事情完全相反。

例子：

struct JobSeekerDataAPI : Decodable 
{ 
    let job_seeker_id: String? 
    let job_seeker_name: String? 
    //Other properties 

    enum CodingKeys: String, CodingKey 
    { 
     case job_seeker_id = "jobSeekerID" //case name is same as property name 
     case job_seeker_name = "jobseekerName" 
     //Other cases 
    } 
}

详细说明，请参阅：https://developer.apple.com/documentation/foundation/archives_and_serialization/encoding_and_decoding_custom_types

你需要为你想成为Decodable所有structs这样做。

这一定会解决您的问题。

编辑：获得零JSON响应数据

我你正在nil解码后，请检查你的API响应返回。我已经包括了你的API响应应该是什么样子的代码片段，你会得到结果是什么：

class JobSeekerJsonRequests: NSObject 
{ 
    class func jobSeekerRequest(completion: @escaping(_ error: Error?, _ jobSeekerData : JobSeekerDataAPI?) ->Void) 
    { 
     let jsonResponseString = "{\"jobSeekerID\":\"1234\",\"jobseekerName\":\"abcd\"}" //Something like this must be the format of your JSON response. Check the key names that are used here. 
     guard let data = jsonResponseString.data(using: .utf8) else { 
      return 
     } 

     do 
     { 
      let jobSeekerData = try 
      JSONDecoder().decode(JobSeekerDataAPI.self, from: data) 
      print(jobSeekerData) 
     } 
     catch let jsonError 
     { 
      print("Error serializing json: ", jsonError) 
     } 
    } 

    func userData() 
    { 
     //Your code 
    } 
}

输出你会得到执行print(jobSeekerData)语句后：

JobSeekerDataAPI(job_seeker_id: Optional("1234"), job_seeker_name: Optional("abcd"))

刚请确保您使用正确的密钥名称，因为您的结果完全取决于它。

注：首先测试用更少的属性数你的代码struct使调试容易。添加更多的代码使得难以调试问题。所以，从小开始，然后最终变大。

让我知道你是否仍然面临任何问题。

我注意到这个名字是不一样的，你提到。我不理解的是因为它仍然在结构中返回nil和相同的错误。我不喜欢：结构名称：可解{ 让varName的（exatcly等于API密钥）：字符串（）枚举CodingKeys：字符串，CodingKey { 情况下的varName = “API KEY” } } 我也跟着苹果文档中的步骤。 – Khromos

我已经更新了我的答案。 – PGDev

太棒了！我会在这里测试它。谢谢！：D – Khromos

你忘了添加CodingKeys为低于enum CodingKeys: String, CodingKey

let most_recent_work_history: WorkHistory? 
let most_recent_education: EducationHistory?
