[英]Swift POST Request not working
I have this server set up with NodeJS that can receive a name and an email and let me know if they match.It can also let me know if the received data is not valid. 我使用NodeJS设置了该服务器,可以接收名称和电子邮件,并让我知道它们是否匹配,还可以让我知道接收到的数据是否无效。
This is my code in swift: 这是我的代码迅速:
func post() {
let parameters = [
"email": "windvaan@live.nl",
"password": "Dittoenbram1234!"
]
let url = NSURL(string: "http://localhost:3000/login")
var request = URLRequest(url: url! as URL)
request.httpMethod = "POST"
guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: JSONSerialization.WritingOptions.prettyPrinted) else {
return
}
request.httpBody = httpBody
let session = URLSession.shared
session.dataTask(with: request) { (data, response, error) in
if let data = data {
do {
let json = try JSONSerialization.jsonObject(with: data, options: [])
print(json)
} catch {
print(error.localizedDescription)
}
}
}.resume()
}
When I call this function my server says that the data is not valid, but the data I put as the parameters is. 当我调用此函数时,服务器会说数据无效,但我作为参数输入的数据是有效的。 I believe it has something to do with this function and the parameters because my server is working fine.
我认为这与该功能和参数有关,因为我的服务器工作正常。 Thx in advance!
提前谢谢!
I figured it out, I had to add in this in my swift file: 我想通了,我不得不在我的快速文件中添加:
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
As per as your parameters value, it's not in valid JSON format. 根据您的参数值,它不是有效的JSON格式。 When you print your parameters value it will print - ["password": "Dittoenbram1234!", "email": "windvaan@live.nl"] , which is invalid.
当您打印参数值时,它将打印-[“” password“:” Dittoenbram1234!“,” email“:” windvaan@live.nl“],这是无效的。
You need to have this format - { email = "windvaan@live.nl"; 您需要使用以下格式-{email =“ windvaan@live.nl”; password = "Dittoenbram1234!";}
密码=“ Dittoenbram1234!”;}
For this 为了这
Replace this - 取代这个-
let parameters = [
"email": "windvaan@live.nl",
"password": "Dittoenbram1234!"
]
With this - 有了这个 -
let parameters: NSDictionary = [
"email": "windvaan@live.nl",
"password": "Dittoenbram1234!"
]
Hope this will help you. 希望这会帮助你。 :)
