Facebook登录 - 获取用户数据 [英] Facebook Login - Get User Data
问题描述
这样做，我先使用Parse Facebook SDK，首先将Facebook链接到我的Parse用户然后查询他的数据并保存。
问题是：有时候我没有收到一些像eMail（userData [@email]为nil），first_name，name ..或Profile Pic不下载。
并不是所有的时间（实际上很少见），并且不可能可靠地复制问题，所以我可以解决它。而且通常只有一个缺失的字段不是全部。
所以我在数据库中有漏洞（当用户的电子邮件地址不好， 我的主要关注 ）
这是我如何编写我的方法（我编辑了大多数if（错误）管理来缩短）。
任何想法？
谢谢你们！
NSArray * permissionsArray = @ [@public_profile，@email，@user_friends];
[PFFacebookUtils initializeFacebook];
//登录PFUser使用Facebook
[PFFacebookUtils logInWithPermissions：permissionsArray block：^（PFUser * user，NSError * error）{
if（user.isNew）{
NSLog（@用户注册并登录！）;
[self fbData：self];
} else {
NSLog（@用户已登录！）;
[self fbDataAlreadyLog：self];
}
}];
然后我调用我的fbData函数，以便将用户数据填写到Parse： p>
- （IBAction）fbData：（id）sender {
[PFFacebookUtils initializeFacebook];
FBRequest * request = [FBRequest requestForMe];
//向Facebook发送请求
[request startWithCompletionHandler：^（FBRequestConnection * connection，NSDictionary< FBGraphUser> * userCloud，NSError * error）{
if（！error）{
//结果是一个带有用户Facebook数据的字典
NSDictionary * userData = userCloud;
NSString * facebookID = userData [@id];
NSURL * pictureURL = [NSURL URLWithString：[NSString stringWithFormat：@https://graph.facebook.com/%@/picture?type=large&return_ssl_resources=1，facebookID]];
PFUser * user = [PFUser currentUser];
if（userData [@name]）{
user [@name] = userData [@name];
}
if（userData [@first_name]）{
user [@first_name] = userData [@first_name];
}
if（userData [@last_name]）{
user [@last_name] = userData [@last_name];
}
if（userData [@id]）{
user [@fbID] = userData [@id];
}
if（userData [@gender]）{
user [@gender] = userData [@gender];
}
if（userData [@email]）{
user.email = userData [@email];
user.username = userData [@email];
}
if（userData [@age_range]）{
user [@age_range] = userData [@age_range];
}
SDWebImageManager * manager = [SDWebImageManager sharedManager];
[manager downloadImageWithURL：pictureURL
options：0
progress：^（NSInteger receivedSize，NSInteger expectedSize）
{
//进度跟踪代码
}
完成：^（UIImage * image，NSError *错误，SDImageCacheType cacheType，BOOL完成，NSURL * imageURL）
{
if（image）
{
// do图像
NSData * imageNSData = UIImagePNGRepresentation（image）;
PFFile * imageFile = [PFFile fileWithName：@profilePicdata：imageNSData];
user [@image] = imageFile;
[user saveInBackgroundWithBlock];
//一旦保存块完成，我再管理一些东西，然后再转到下一个ViewController
}
}];
}];
尝试这样
NSArray * permissionsArray = @ [@user_about_me，@user_relationships，@user_birthday，@user_location];
I'm building an app on iOS using Parse as a backend.
Doing so I use the Parse Facebook SDK in order first to link Facebook to my Parse User and then to query his data and save them.
The Problem is: sometimes I don't get some of the info like eMail (userData[@"email"] is nil), first_name,name .., or the Profile Pic doesn't download.
Not all the time (quite rare actually), and impossible to reliably replicate the issue so I can solve it. And it's often only one missing field not all.
So I got holes in my Database (not cool when it is the user's email address: my main concern)
Here is how I wrote my methods (i edited most of the if(error) management to make it shorter).
Any ideas ?
Thank you guys !
NSArray *permissionsArray = @[@"public_profile",@"email", @"user_friends"];
[PFFacebookUtils initializeFacebook];
// Login PFUser using Facebook
[PFFacebookUtils logInWithPermissions:permissionsArray block:^(PFUser *user, NSError *error) {
if (user.isNew) {
NSLog(@"User with facebook signed up and logged in!");
[self fbData:self];
} else {
NSLog(@"User with facebook logged in!");
[self fbDataAlreadyLog:self];
}
}];
Then I call my "fbData" function in order to fill in the user data into Parse:
-(IBAction)fbData:(id)sender{
[PFFacebookUtils initializeFacebook];
FBRequest *request = [FBRequest requestForMe];
// Send request to Facebook
[request startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *userCloud, NSError *error) {
if (!error) {
// result is a dictionary with the user's Facebook data
NSDictionary *userData = userCloud;
NSString *facebookID = userData[@"id"];
NSURL *pictureURL = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=large&return_ssl_resources=1", facebookID]];
PFUser *user = [PFUser currentUser];
if (userData[@"name"]) {
user[@"name"] = userData[@"name"];
}
if (userData[@"first_name"]) {
user[@"first_name"] = userData[@"first_name"];
}
if (userData[@"last_name"]) {
user[@"last_name"] = userData[@"last_name"];
}
if (userData[@"id"]) {
user[@"fbID"] = userData[@"id"];
}
if (userData[@"gender"]) {
user[@"gender"] = userData[@"gender"];
}
if (userData[@"email"]) {
user.email = userData[@"email"];
user.username = userData[@"email"];
}
if (userData[@"age_range"]) {
user[@"age_range"] = userData[@"age_range"];
}
SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager downloadImageWithURL:pictureURL
options:0
progress:^(NSInteger receivedSize, NSInteger expectedSize)
{
// progression tracking code
}
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, BOOL finished,NSURL *imageURL)
{
if (image)
{
// do something with image
NSData *imageNSData = UIImagePNGRepresentation(image);
PFFile *imageFile = [PFFile fileWithName:@"profilePic" data:imageNSData];
user[@"image"] = imageFile;
[user saveInBackgroundWithBlock];
//Once the Save Block is done I managed a few more thing before moving on to the next ViewController
}
}];
}];
try like this
NSArray *permissionsArray = @[ @"user_about_me", @"user_relationships", @"user_birthday", @"user_location"];
