【问题描述】:
所以我正在尝试在 Swift 中制作一个应用程序,我需要为此登录 OAuth 以检索访问令牌。 API 采用参数“grant_type”和“code”。
我试过了:
let params = ["grant_type":"authorization_code", "code":"123456789"] as Dictionary<String, String>
var request = URLRequest(url: URL(string: "https://myschool.zportal.nl/api/v3/oauth/token")!)
request.httpMethod = "POST"
request.httpBody = try? JSONSerialization.data(withJSONObject: params, options: [])
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
let session = URLSession.shared
let task = session.dataTask(with: request, completionHandler: { data, response, error -> Void in
do {
let json = try JSONSerialization.jsonObject(with: data!) as! Dictionary<String, AnyObject>
print(json)
} catch {
print("error")
}
})
task.resume()
这会返回:
["response": {
data = (
);
details = "class org.springframework.web.bind.MissingServletRequestParameterException: Required String parameter 'grant_type' is not present";
endRow = 0;
eventId = 216795;
message = "Internal problems.";
startRow = 0;
status = 500;
totalRows = 0;
}]
这很奇怪,因为我确实将“grant_type”参数解析为正确的值。
它应该返回类似:
{
"response": {
"status":200,
"message":"",
"startRow":0,
"endRow":27,
"totalRows":27,
"data":[
{
},
...
]
}
}
