swift - 如何使用 UrlSession.DataTaskPublisher 调用发布 Web 服务？

Question

我有一个简单的问题，我只能在documentation中看到dataTaskPublisher我可以通过它调用 get web 服务，但是如何调用可以返回发布者的 post web 服务呢？

Answer 1

您可以定义一个请求并在 dataTaskPublisher 中调用它，如下所示:

var request =  URLRequest(url: URL(string: "url")!)
let session = URLSession.shared
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.HTTPBody = try! JSONSerialization.dataWithJSONObject(parameters, options: [])
session.dataTaskPublisher(for: request)
