Question

嗨我在swift中遇到JSON序列化问题。

我的代码如下：

var username = "xcode"
var password = "pass"

let json = ["username":username, "password":password]
let jsonData = try JSONSerialization.data(withJSONObject: json, options: .prettyPrinted)
var request = URLRequest(url: URL(string: "myServer")!)

request.httpMethod = "POST"
request.httpBody = jsonData

我的问题是，当我向服务器发出请愿书（工作正常）时，它会返回给我这行代码：

responseString = Optional("{\"username\":[\"This field is required.\"],\"password\":[\"This field is required.\"]}")

我做错了什么？

谢谢。

代码应为：

var username = "xcode"
var password = "pass"
let json = ["username":username, "password":password]
let jsonData = try JSONSerialization.data(withJSONObject: json, options: .prettyPrinted)
var request = URLRequest(url: URL(string: "http://10.192.118.193:8000/users/")!)

request.httpMethod = "POST"
request.httpBody = jsonData
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")

带有JSON的HTTP POST请求
