ios - 如何在 iOS 中使用 Twitter API 1.1 获取 Token

Question

我正在使用“STTwitter”从下面的 URL 和请求正文中获取 token

https://dev.twitter.com/docs/api/1.1/post/oauth2/token

带有URL的请求正文代码如下

- (void)verifyCredentialsWithSuccessBlock:(void(^)(NSString *username))successBlock errorBlock:(void(^)(NSError *error))errorBlock {

    [self postResource:@"oauth2/token"
         baseURLString:@"https://api.twitter.com"
            parameters:@{ @"grant_type" : @"client_credentials" }
          useBasicAuth:YES
   uploadProgressBlock:nil
 downloadProgressBlock:nil
          successBlock:^(id request, NSDictionary *requestHeaders, NSDictionary *responseHeaders, id json) {

              NSString *tokenType = [json valueForKey:@"token_type"];
              if([tokenType isEqualToString:@"bearer"] == NO) {
                  NSError *error = [NSError errorWithDomain:NSStringFromClass([self class]) code:STTwitterAppOnlyCannotFindBearerTokenInResponse userInfo:@{NSLocalizedDescriptionKey : @"Cannot find bearer token in server response"}];
                  errorBlock(error);
                  return;
              }

              self.bearerToken = [json valueForKey:@"access_token"];

              successBlock(_bearerToken);

          } errorBlock:^(id request, NSDictionary *requestHeaders, NSDictionary *responseHeaders, NSError *error) {
              errorBlock(error);


              NSLog(@"ERROR %@",[error description]);

          }];
}

为了调用上面的方法我正在做下面的代码

STTwitterAppOnly *twitter1 = [[STTwitterAppOnly alloc] init];
    [twitter1 verifyCredentialsWithSuccessBlock:^(NSString *bearerToken) {

        NSLog(@"sd");

        [self.twitter getUserTimelineWithScreenName:@"SEREEN_NAME"
                                  successBlock:^(NSArray *statuses) {

                                      NSLog(@"ERROR ::: %@",[statuses description]);

                                      // ...
                                  } errorBlock:^(NSError *error) {
                                      // ...
                                  }];

    } errorBlock:^(NSError *error) {
        // ...
    }];

执行上面的代码时出现以下错误...

**Error Domain=STHTTPRequest Code=99 "Unable to verify your credentials"** 

你能告诉我我在代码中遗漏了什么吗？

我担心的是，我想在不登录 Twitter 的情况下阅读 Twitter 提要。仅在 Twitter API V1.1 中使用“Consumer Key”和“Secret Key”。

谢谢

如果你有ConsumerKey和ConsumerSecret你可以试试

STTwitterAPIWrapper *twitterAPI = [[STTwitterAPIWrapper twitterAPIApplicationOnlyWithConsumerKey:@"Your Consumer Key" consumerSecret:@"Your Consumer Secret"] autorelease];
[twitterAPI verifyCredentialsWithSuccessBlock:^(NSString *username) {
     [twitterAPI getUserTimelineWithScreenName:@"your ScreenName" count:25 successBlock:^(NSArray *statuses) {
         NSLog(@"Success:%@", statuses);

     } errorBlock:^(NSError *error){
         NSLog(@"Error : %@",error.description);
     }];

} errorBlock:^(NSError *error) {
         NSLog(@"Error : %@",error.description);
}];
