Feedly 标记为 Read 在 Objective-C 上不起作用

Question

我正在尝试在我的iOS应用程序中实现一种方法，以使用Feedly API将文章标记为已读。但是，我不断收到错误响应：

{
    "errorCode": 400,
    "errorId": "sandbox-he.2015010906.2770040",
    "errorMessage": "no data"
}

这是方法：

- (void)markRead:(NSString*)articleID {
    NSLog(@"Artidle ID is: %@", articleID);
    NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];
    NSString *accessToken = [standardUserDefaults objectForKey:@"AccessToken"];
    NSString *feedUrl = [NSURL URLWithString:@"https://sandbox.feedly.com/v3/markers"];
    NSError *error = nil;
    NSString *post =[[NSString alloc] initWithFormat:@"action=markAsRead&type=entries&entryIds=%@",articleID];
    NSLog(@"PostData: %@",post);
    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setURL:feedUrl];
    [request setHTTPMethod:@"POST"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-type"];
    [request setHTTPBody:postData];
    [request addValue:accessToken forHTTPHeaderField:@"Authorization"];
    //[NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:[url host]];
    NSError *errror = [[NSError alloc] init];
    NSHTTPURLResponse *response = nil;
    NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&errror];
    NSLog(@"Response code: %ld", (long)[response statusCode]);
    if ([response statusCode] >= 200 && [response statusCode] < 300)
    {
        NSLog(@"Success marking this as read.");
    } else {
        if (error) NSLog(@"Error: %@", errror);
        NSLog(@"No success marking this as read.");
    }
}

Feedly API 描述它需要这个作为输入：

{
   "entryIds": [
       "TSxGHgRh4oAiHxRU9TgPrpYvYVBPjipkmUVSHGYCTY0=_14499073085:c034:d32dab1f",
       "TSxGHgRh4oAiHxRU9TgPrpYvYVBPjipkmUVSHGYCTY0=_1449255d60a:22c3491:9c6d71ab"
   ],
   "action": "markAsRead",
   "type": "entries"
}

在我看来，我将其作为输入提供，所以我实际上期望得到适当的回应。然而，我一直在400，似乎无法弄清楚我做错了什么。我已经为此绞尽脑汁了几个小时。

尝试使用以下代码创建数据，而不是使用当前的身体数据：

NSDictionary *bodyDict = [NSDictionary dictionaryWithObjectsAndKeys:@[articleID],@"entryIds",
                          @"markAsRead",@"action",
                          @"entries",@"type", nil];
NSError *error;
NSData *postdata = [NSJSONSerialization dataWithJSONObject:bodyDict options:0 error:&error];
[request setHTTPBody:postData];

这会将正文作为 JSON 对象发送。

像你一样发送参数（使用 action=markAsRead&type=entries&entryIds=%@ ）通常在使用 GET 请求方法调用 Web 方法时使用。看看 POST vs GET 以获得更好的理解。
