我有一个iOS应用程序,通过OAuth 2.0对Google Plus API进行身份验证。我遇到的问题是,即使我完全按照Google文档操作,我也无法发布。这是我的POST请求:
NSString *gp_moment = [NSString stringWithFormat:@"https://www.googleapis.com/plus/v1/people/me/moments/vault?access_token=%@", token_gplus];
NSString *urlString = gp_moment;
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
// Set the header - Content-Type.
NSDictionary *the_header = @{@"Content-type" : @"application/json",
@"userId" : @"me",
@"collection" : @"vault",
@"requestvisibleactions" : @"http://schemas.google.com/AddActivity"};
[request setAllHTTPHeaderFields:the_header];
// Set the metadata for the GP Moment (eg: name). - request_visible_actions
NSDictionary *metadata = @{@"target" : @{
@"id" : @"replacewithuniqueidforaddtarget",
@"image" : @"http://www.google.com/s2/static/images/GoogleyEyes.png",
@"type": @"http://schema.org/CreativeWork",
@"description" : @"test_desc",
@"name" : @"TESTNAME",
},
@"type" : @"http://schemas.google.com/AddActivity"};
// Convert metadata into JSON format and submit.
NSError *jError = nil;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:metadata options:NSJSONWritingPrettyPrinted error:&jError];
[request setHTTPBody:jsonData];
NSHTTPURLResponse *response = nil;
NSError *error = nil;
NSData *returnedData;
returnedData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSDictionary *headers = [response allHeaderFields];
NSLog(@"DATA: %@", [[NSString alloc] initWithData:returnedData encoding:NSASCIIStringEncoding]);
NSLog(@"%@", headers);
NSLog(@"%@", response);
NSLog(@"%@", error);
更新 - 我如何获得OAUTH
我使用Google提供的GTMOAuth2 iOS库获取令牌。它有4个主要类我正在使用:
这是我从类到ViewController实现的代码:
-(GTMOAuth2Authentication *)begin_authorization {
// Set the token URL to the token endpoint.
NSURL *tokenURL;
// Set a bogus redirect URI. It won't actually be used as the redirect will
// be intercepted by the OAuth library and handled in the app.
NSString *redirectURI;
GTMOAuth2Authentication *auth;
tokenURL = [NSURL URLWithString:@"https://accounts.google.com/o/oauth2/token"];
redirectURI = @"http://localhost:3000/oauth/callback/";
auth = [GTMOAuth2Authentication authenticationWithServiceProvider:@"GooglePlus" tokenURL:tokenURL redirectURI:redirectURI clientID:kMyClientID_gplus clientSecret:kMyClientSecret_gplus];
[auth setScope:@"https://www.googleapis.com/auth/plus.login"];
// Set the appropriate token type.
[auth setTokenType:@"Bearer"];
return auth;
}
-(void)authorize:(NSString *)service {
GTMOAuth2Authentication *auth = [self begin_authorization];
// Prepare the Authorization URL. We will pass in the name of the service
// that we wish to authorize with.
NSURL *authURL;
authURL = [NSURL URLWithString:[NSString stringWithFormat:@"https://accounts.google.com/o/oauth2/auth/"]];
NSString *keyname;
keyname = [NSString stringWithFormat:@"GooglePlus"];
// Display the authentication view
GTMOAuth2ViewControllerTouch *viewController;
viewController = [[GTMOAuth2ViewControllerTouch alloc] initWithAuthentication:auth authorizationURL:authURL keychainItemName:keyname delegate:self finishedSelector:@selector(viewController:finishedWithAuth:error:)];
[viewController setBrowserCookiesURL:[NSURL URLWithString:@"https://accounts.google.com/o/oauth2/auth/"]];
// Push the authentication view to our navigation controller instance
[[self navigationController] pushViewController:viewController animated:YES];
}
-(void)viewController:(GTMOAuth2ViewControllerTouch *)viewController finishedWithAuth:(GTMOAuth2Authentication *)auth error:(NSError *)error {
if (error != nil) {
// Authentication failed
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Authorization Failed" message:[error localizedDescription] delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
[alertView show];
}
else {
// Authentication succeeded
// Assign the access token to the instance property for later use
account_check = auth.accessToken;
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:account_check forKey:@"gp_token"];
[defaults synchronize];
}
}
在GTMOAuth2SignIn.m文件中,我还设置了offline_access和" requestvisisbleactions"像这样的参数:
NSMutableDictionary *paramsDict = [NSMutableDictionary dictionaryWithObjectsAndKeys:
@"code", @"response_type",
clientID, @"client_id",
scope, @"scope", // scope may be nil
@"force", @"approval_prompt",
@"offline", @"access_type",
@"http://schemas.google.com/AddActivity", @"requestvisibleactions",
nil];
更新 - 2
我尝试查看所有Google Plus文档以及查看" requestvisisbleactions"之间的差异。和" request_visisble_actions"仍然没有任何作用。有谁知道出了什么问题?
更新 - 3 - 我仍然遇到的错误
我一直在从Google Plus API中收到此错误。我只是不知道为什么......:
{
"error": {
"errors": [
{
"domain": "global",
"reason": "unauthorized",
"message": "Unauthorized"
}
],
"code": 401,
"message": "Unauthorized"
}
}
答案 0 :(得分:4)
我相信您需要使用request_visible_actions
。因此您的参数可能设置为
NSMutableDictionary *paramsDict = [NSMutableDictionary dictionaryWithObjectsAndKeys:
@"code", @"response_type",
clientID, @"client_id",
scope, @"scope", // scope may be nil
@"force", @"approval_prompt",
@"offline", @"access_type",
@"http://schemas.google.com/AddActivity", @"request_visible_actions",
nil];
