ios - 如何在 swift 4 中使用 json 对象发送 json 数据
<p><p>我需要按以下顺序将 json 发送到服务器</p>
<pre><code>data:{"firstname":"Alpha","lastname":"Beta"}
</code></pre>
<p> <a href="/image/uIYR9.png" rel="noreferrer noopener nofollow"><img src="/image/uIYR9.png" alt="enter image description here"/></a> </p>
<p>在这种情况下,数据键在 <code></code> 之类的 json 之外,但是当我进行序列化时,它将请求作为 </p>
<pre><code>{
"data" : {
"firstname" : "alpha",
"lastname" : "beta"
}
}
</code></pre>
<p>这些是我的模型:</p>
<pre><code>struct UserDetail :Codable {
let data :CreateProfileModel
}
struct CreateProfileModel :Codable {
let firstname :String
let lastname :String
}
</code></pre>
<p>我在这些模型中添加的数据</p>
<pre><code>let profileInfo = CreateProfileModel(firstname: "alpha" , lastname: "beta")
let userDetails = UserDetail(data: profileInfo)
</code></pre>
<p>这是我使用 swift 进行的 json 编码:</p>
<pre><code> let jsonEncoder = JSONEncoder()
jsonEncoder.outputFormatting = .prettyPrinted
do{
let userData = try jsonEncoder.encode(userDetails)
print(String(data: userData, encoding: .utf8)!)
networkListener.requestPost(endpoint: endpoint, data: userData , headerValue: nil)
}catch{
print(error)
}
</code></pre>
<p>在 requestPost 方法中</p>
<pre><code>func requestPost(endpoint : String , data :Data,headerValue : String?){....
request.httpbody = data
}
</code></pre>
<p>我正在将该数据添加到 <code>request.httpbody</code>。</p>
<p>如何使用 profileInfo 添加数据键? </p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>试试这个代码:</p>
<pre><code>var columnValus:= [:]
columnValus["firstname"] = userDetails.data.firstname
columnValus["lastname"] = userDetails.data.lastname
let userData = [
"data": columnValus
] as
do {
let postData = try JSONSerialization.data(withJSONObject: userData, options: [])
networkListener.requestPost(endpoint: endpoint, data: postData , headerValue: nil)
}catch let error as NSError {
print(error)
}
</code></pre></p>
