获取推特朋友列表? [英] Get twitter friends list?
问题描述
我在twitter好友/列表API中得到了Bad Authentication data响应.登录时得到用户名，屏幕名称，authToken和authTokenSecret.
I'm getting Bad Authentication data response in twitter friends/list API. I'm getting userid, screen name, authToken and authTokenSecret when login.
func loadFollowers(userid:String) {
//let twapi = "https://api.twitter.com/1.1/followers/list.json?cursor=-1&user_id=\(session)&count=5000"
let twapi = "https://api.twitter.com/1.1/friends/list.json?cursor=-1&user_id=\(userid)&count=10"
let url2 = URL(string: twapi)!
print(url2)
URLSession.shared.dataTask(with: url2, completionHandler: { (data, response, error) in
//UIApplication.shared.isNetworkActivityIndicatorVisible = false
do {
let userData = try JSONSerialization.jsonObject(with: data!, options:[])
print(userData)
} catch {
NSLog("Account Information could not be loaded \(error)")
}
}).resume()
}
输出:
{
"errors": [
{
"code": 215,
"message": "Bad Authentication data."
}
]
}

推荐答案
在Swift 4.2，Xcode 10.1和iOS 12.1
In Swift 4.2, Xcode 10.1 and iOS 12.1
最后，我得到了解决方案.首先，我们需要授权，然后需要实现好友列表api.
Finally i got the solution for this. Here first we need Authorisation then need to implement friends list api.
纯Swift代码不可用.但是我完全是迅速实现的.
Pure Swift code is not available. But i implemented in pure swift.
如果要从Twitter获取朋友/列表数据，则需要使用两个API .
If you want to get friends/list data from twitter you need to use two API's.
1)oauth2/令牌 API
2)朋友/列表API
在 oauth2/token api中，您可以获得访问令牌，因为您需要访问令牌来访问好友列表.并且您需要用户ID，屏幕名称.
In oauth2/token api you can get access token, because you need access token for friends list. And you need user id, screen name.
但是在这里，您必须记住一个要点.
But here you must remember one important point.
1)首先使用 oauth2/token api作为访问令牌.
1) First use oauth2/token api for access token.
2)获取访问令牌后，使用 twitter登录 API来获取用户ID和屏幕名称.
2) After getting access token use twitter login api for user id and screen name.
3)现在使用朋友/列表 api.
3) Now use friends/list api.
首先，如果您使用 twitter登录，然后使用oauth2/token api作为访问令牌，则会收到类似 Bad Authentication data 的错误消息.因此，请按以下3个步骤进行操作.
Here first if you use twitter login then oauth2/token api for access token, you can get like Bad Authentication data error. So you please follow above 3 steps in order.
1)获取访问令牌代码(oauth2/令牌api):
func getAccessToken() {
//RFC encoding of ConsumerKey and ConsumerSecretKey
let encodedConsumerKeyString:String = "sx5r...S9QRw".addingPercentEncoding(withAllowedCharacters: CharacterSet.urlHostAllowed)!
let encodedConsumerSecretKeyString:String = "KpaSpSt.....tZVGhY".addingPercentEncoding(withAllowedCharacters: CharacterSet.urlHostAllowed)!
print(encodedConsumerKeyString)
print(encodedConsumerSecretKeyString)
//Combine both encodedConsumerKeyString & encodedConsumerSecretKeyString with " : "
let combinedString = encodedConsumerKeyString+":"+encodedConsumerSecretKeyString
print(combinedString)
//Base64 encoding
let data = combinedString.data(using: .utf8)
let encodingString = "Basic "+(data?.base64EncodedString())!
print(encodingString)
//Create URL request
var request = URLRequest(url: URL(string: "https://api.twitter.com/oauth2/token")!)
request.httpMethod = "POST"
request.setValue(encodingString, forHTTPHeaderField: "Authorization")
request.setValue("application/x-www-form-urlencoded;charset=UTF-8", forHTTPHeaderField: "Content-Type")
let bodyData = "grant_type=client_credentials".data(using: .utf8)!
request.setValue("\(bodyData.count)", forHTTPHeaderField: "Content-Length")
request.httpBody = bodyData
let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil else { // check for fundamental networking error
print("error=\(String(describing: error))")
return
}
let responseString = String(data: data, encoding: .utf8)
let dictionary = data
print("dictionary = \(dictionary)")
print("responseString = \(String(describing: responseString!))")
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(String(describing: response))")
}
do {
let response = try JSONSerialization.jsonObject(with: data, options: []) as! Dictionary<String, Any>
print("Access Token response : \(response)")
print(response["access_token"]!)
self.accessToken = response["access_token"] as! String
self.getStatusesUserTimeline(accessToken:self.accessToken)
} catch let error as NSError {
print(error)
}
}
task.resume()
}
输出:
{"token_type":"bearer","access_token":"AAAAAAAAAAAAAAAAAAA............xqT3t8T"}
2)使用Twitter代码登录
@IBAction func onClickTwitterSignin(_ sender: UIButton) {
//Login and get session
TWTRTwitter.sharedInstance().logIn { (session, error) in
if (session != nil) {
//Read data
let name = session?.userName ?? ""
print(name)
print(session?.userID ?? "")
print(session?.authToken ?? "")
print(session?.authTokenSecret ?? "")
// self.loadFollowers(userid: session?.userID ?? "")
//Get user email id
let client = TWTRAPIClient.withCurrentUser()
client.requestEmail { email, error in
if (email != nil) {
let recivedEmailID = email ?? ""
print(recivedEmailID)
} else {
print("error--: \(String(describing: error?.localizedDescription))");
}
}
//Get user profile image url's and screen name
let twitterClient = TWTRAPIClient(userID: session?.userID)
twitterClient.loadUser(withID: session?.userID ?? "") { (user, error) in
print(user?.profileImageURL ?? "")
print(user?.profileImageLargeURL ?? "")
print(user?.screenName ?? "")
}
let storyboard = self.storyboard?.instantiateViewController(withIdentifier: "SVC") as! SecondViewController
self.navigationController?.pushViewController(storyboard, animated: true)
} else {
print("error: \(String(describing: error?.localizedDescription))");
}
}
}
输出:
在这里您将获得userName，userId，authtoken，authTokenSecret，屏幕名称和电子邮件等.
Here you will get userName, userId, authtoken, authTokenSecret, screen name and email etc.
3)现在从朋友/列表api"中获取朋友列表.在这里，您可以获取朋友/列表，用户/查找，关注者/id，关注者/列表api的数据等...
3) Now get friends list from friends/list api. Here you can get friends/list, users/lookup, followers/ids, followers/list api's data etc...
func getStatusesUserTimeline(accessToken:String) {
let userId = "109....456"
let twitterClient = TWTRAPIClient(userID: userId)
twitterClient.loadUser(withID: userId) { (user, error) in
if user != nil {
//Get users timeline tweets
var request = URLRequest(url: URL(string: "https://api.twitter.com/1.1/friends/list.json?screen_name=KS....80&count=10")!) //users/lookup, followers/ids, followers/list
request.httpMethod = "GET"
request.setValue("Bearer "+accessToken, forHTTPHeaderField: "Authorization")
let task = URLSession.shared.dataTask(with: request) { data, response, error in guard let data = data, error == nil else { // check for fundamental networking error
print("error=\(String(describing: error))")
return
}
// let responseString = String(data: data, encoding: .utf8)
// let dictionary = data
// print("dictionary = \(dictionary)")
// print("responseString = \(String(describing: responseString!))")
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(String(describing: response))")
}
do {
let response = try JSONSerialization.jsonObject(with: data, options: [])
print(response)
} catch let error as NSError {
print(error)
}
}
task.resume()
}
}
}
此代码在任何地方均不可用.我为此代码做了很多尝试，为此花了很多时间.谢谢.
This code not available any where. I tried a lot for this code and i spent lot of time for this. Thank you.
