使用 twitterkit 将图片发布到 Twitter
Posting image to twitter using twitterkit
我正在尝试 post 使用带有自定义 UI 的 Twitter 新 TwitterKit 制作图像和推文。他们提供的唯一文档是如何用他们的观点来做。
所以我可以弄清楚如何在没有图像的情况下做到这一点
NSMutableDictionary *message = [[NSMutableDictionary alloc] initWithObjectsAndKeys:[params objectForKey:@"description"],@"status",@"true",@"wrap_links", nil];
NSURLRequest* request = [twAPIClient URLRequestWithMethod:@"POST" URL:@"https://api.twitter.com/1.1/statuses/update.json" parameters:message error:nil];
[twAPIClient sendTwitterRequest:request completion:^(NSURLResponse* response, NSData* data, NSError* connectionError){
}];
但是他们的 URLRequestWithMethod 方法是不可变的。我将如何向其中添加图像。您曾经使用
的 SLRequest 来完成它
[postRequest addMultipartData:UIImageJPEGRepresentation(image, 0.5) withName:@"media" type:@"image/jpeg" filename:@"image.png"];
我想通了。
首先，您需要post 将图像发送到 Twitter。
NSString *media = @"https://upload.twitter.com/1.1/media/upload.json";
NSData *imageData = UIImageJPEGRepresentation(image, 0.9);
NSString *imageString = [corgiData base64EncodedStringWithOptions:0];
NSURLRequest *request = [client URLRequestWithMethod:@"POST" URL:media parameters:@{@"media":imageString} error:&requestError];
[[[Twitter sharedInstance] APIClient] sendTwitterRequest:request completion:^(NSURLResponse *urlResponse, NSData *data, NSError *connectionError) {
}];
然后在响应对象中使用 media_id_string 并将其添加到我问题中代码的参数中。
所以
NSMutableDictionary *message = [[NSMutableDictionary alloc] initWithObjectsAndKeys:[params objectForKey:@"description"],@"status",@"true",@"wrap_links",mediaIDString, @"media_ids", nil];
NSURLRequest* request = [twAPIClient URLRequestWithMethod:@"POST" URL:@"https://api.twitter.com/1.1/statuses/update.json" parameters:message error:nil];
[twAPIClient sendTwitterRequest:request completion:^(NSURLResponse* response, NSData* data, NSError* connectionError){
NSDictionary *responseDict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&parsingError];
}];
注意第一个请求的响应中的 media_ids 对象
NSMutableDictionary *message = [[NSMutableDictionary alloc] initWithObjectsAndKeys:[params objectForKey:@"description"],@"status",@"true",@"wrap_links",[responseDict objectForKey:@"media_id_string"], @"media_ids", nil];
所以你可以把它放在完成块中，它会 post 图片和推文。
Swift
func post (tweetString: String, tweetImage: NSData) {
let uploadUrl = "https://upload.twitter.com/1.1/media/upload.json"
let updateUrl = "https://api.twitter.com/1.1/statuses/update.json"
let imageString = tweetImage.base64EncodedStringWithOptions(NSDataBase64EncodingOptions())
let request = Twitter.sharedInstance().APIClient.URLRequestWithMethod("POST",
URL: uploadUrl, parameters: ["media": imageString], error: nil)
Twitter.sharedInstance().APIClient.sendTwitterRequest(request, completion: { (urlResponse, data, connectionError) -> Void in
if let mediaDict = self.nsdataToJSON(data!) {
let validTweetString = TweetValidator().validTween(tweetString)
let message = ["status": validTweetString, "media_ids": mediaDict["media_id_string"]]
let request = Twitter.sharedInstance().APIClient.URLRequestWithMethod("POST",
URL: updateUrl, parameters: message, error:nil)
Twitter.sharedInstance().APIClient.sendTwitterRequest(request, completion: { (response, data, connectionError) -> Void in
})
}
})
}
func nsdataToJSON (data: NSData) -> AnyObject? {
do {
return try NSJSONSerialization.JSONObjectWithData(data, options: .MutableContainers)
} catch let myJSONError {
print(myJSONError)
}
return nil
}
截至 2016 年 4 月左右，Fabric 的 TwitterKit 2.0（或更新版本）公开了一种新方法 uploadMedia 来涵盖媒体上传部分。这是一些对我有用的 objc 代码。
(earlier)
self.userID = [[Twitter sharedInstance] sessionStore].session.userID;
- (void)tweetImage:(UIImage*)image {
NSAssert([NSThread currentThread].isMainThread && self.userID, @"Twitterkit needs main thread, with self.userID set");
if (!self.userID)
return;
NSString *tweetStr = @"Look at me! I'm tweeting! #hashtag";
TWTRAPIClient *twitterClient = [[TWTRAPIClient alloc] initWithUserID:self.userID];
NSData *imgData = UIImageJPEGRepresentation(image, 0.6f);
if (!imgData) {
NSAssert(false, @"ERROR: could not make nsdata out of image");
return;
}
[twitterClient uploadMedia:imgData contentType:@"image/jpeg" completion:^(NSString * _Nullable mediaID, NSError * _Nullable error) {
if (error) {
NSAssert(false, @"ERROR: error uploading collage to twitter");
return;
}
NSError *urlerror = nil;
NSURLRequest *request = [twitterClient URLRequestWithMethod:@"POST" URL:@"https://api.twitter.com/1.1/statuses/update.json" parameters:@{ @"status":tweetStr, @"media_ids":mediaID } error:&urlerror];
if (urlerror) {
NSAssert(false, @"ERROR creating twitter URL request: %@", urlerror);
return;
}
[twitterClient sendTwitterRequest:request completion:^(NSURLResponse * _Nullable response, NSData * _Nullable data, NSError * _Nullable connectionError) {
if (!connectionError && ((NSHTTPURLResponse*)response).statusCode != 200) {
DDLogInfo(@"TwitterHelper tweetImage: non-200 response: %d. Data:\n%@", (int)((NSHTTPURLResponse*)response).statusCode, [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);
}
}];
}];

1) 检查登录是否完成
let store = TWTRTwitter.sharedInstance().sessionStore
if let store = store.session() {
print("signed in as \(String(describing: store.authToken))");
print("signed in as \(String(describing: store.authTokenSecret))");
let postImage = UIImage(named: "testImage")
let imageData = UIImagePNGRepresentation(postImage!) as Data?
self.post(tweetString: "Test post image", tweetImage: (imageData! as NSData) as Data, withUserID: store.userID)
}
else {
TWTRTwitter.sharedInstance().logIn(completion: { (session, error) in
if (session != nil) {
print("login first time in twitter as \(String(describing: session?.userName))");
} else {
print("error: \(String(describing: error?.localizedDescription))");
}
})
}
2) 上传带文字的图片
func post(tweetString: String, tweetImage: Data ,withUserID :String) {
let uploadUrl = "https://upload.twitter.com/1.1/media/upload.json"
let updateUrl = "https://api.twitter.com/1.1/statuses/update.json"
let imageString = tweetImage.base64EncodedString(options: NSData.Base64EncodingOptions())
let client = TWTRAPIClient.init(userID: withUserID)
let requestUploadUrl = client.urlRequest(withMethod: "POST", urlString: uploadUrl, parameters: ["media": imageString], error: nil)
client.sendTwitterRequest(requestUploadUrl) { (urlResponse, data, connectionError) -> Void in
if connectionError == nil {
if let mediaDict = self.nsDataToJson(data: (data! as NSData) as Data) as? [String : Any] {
let media_id = mediaDict["media_id_string"] as! String
let message = ["status": tweetString, "media_ids": media_id]
let requestUpdateUrl = client.urlRequest(withMethod: "POST", urlString: updateUrl, parameters: message, error: nil)
client.sendTwitterRequest(requestUpdateUrl, completion: { (urlResponse, data, connectionError) -> Void in
if connectionError == nil {
if let _ = self.nsDataToJson(data: (data! as NSData) as Data) as? [String : Any] {
print("Upload suceess to Twitter")
}
}
})
}
}
}
}
func nsDataToJson (data: Data) -> AnyObject? {
do {
return try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as AnyObject
} catch let myJSONError {
print(myJSONError)
}
return nil
}
注意：安装 pod 文件 pod 'TwitterKit'. 您需要在 appdelegate 和 URL 方案中设置与登录相关的其他小事情（以上代码是与登录和 post 带文字的图像有关）
