OAConsumer API会在接收数据时发生错误
我试图使用OAConsumer API获取数据。 我尝试了下面的代码，它给我一个错误。
-(void)performQuery
{
OAConsumer *consumer = [[OAConsumer alloc] initWithKey:OAUTH_KEY
secret:OAUTH_SECRET];
NSURL *url = [NSURL URLWithString:@"https://api.semantics3.com/v1/products"];
OAMutableURLRequest *request = [[OAMutableURLRequest alloc] initWithURL:url
consumer:consumer
token:nil
realm:nil
signatureProvider:nil]; // use the default method, HMAC-SHA1
[request setHTTPMethod:@"GET"];
[consumer release];
OARequestParameter * qParam = [[OARequestParameter alloc] initWithName:@"q" value:@"{"cat_id":13658,"model":"Satellite"}"];
NSArray *params = [NSArray arrayWithObjects:qParam, nil];
[qParam release];
[request setParameters:params];
OADataFetcher *fetcher = [[OADataFetcher alloc] init];
[fetcher fetchDataWithRequest:request
delegate:self
didFinishSelector:@selector(requestDidFinishWithData:)
didFailSelector:@selector(requestDidFailWithError:)];
[request release];
}
错误如下：
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[OAServiceTicket bytes]: unrecognized selector sent to instance 0x1ed65bf0'
错误发生在这一行上： ** NSString response = [[NSString alloc] initWithData：data encoding：NSUTF8StringEncoding];
- (void)requestDidFinishWithData:(NSData *)data {
NSString *response= [[NSString alloc] initWithData:data
encoding:NSUTF8StringEncoding];
//here do what you want with the response, I use SBJson to parse it.
NSLog(@"Request success!%@", response);
[responseBody release];
}
- (void)requestDidFailWithError:(NSError *)error {
NSLog(@"Request did fail with error: %@", [error localizedDescription]);
}
任何想法我在这里做什么？
当它实际上是一个OAServiceTicket对象时，你试图读取NSData。
OAServiceTicket对象具有以下内容：
request = [aRequest retain];
response = [aResponse retain];
data = [aData retain];
didSucceed = success;
所以你的代表必须如下：
- (void)requestDidFinishWithData:(OAServiceTicket *)ticket {
NSString *response= [[NSString alloc] initWithData:ticket.data
encoding:NSUTF8StringEncoding];
//here do what you want with the response, I use SBJson to parse it.
NSLog(@"Request success!%@", response);
[response release];
}
适用于我。
请检查票是否成功，像这样...
- (void)fetchingVideoTicket:(OAServiceTicket *)ticket didFinishWithData:(NSData *)data{
if(ticket.didSucceed)
{
your code...
}
它似乎在你的情况下，请求是成功的，但没有响应产生，说明你没有包含该请求的所有必需参数，我也遇到了同样的问题，当我试图连接Vimeo，但在我添加回调参数到请求，连接成功并产生响应。 检查是否添加了所有参数。
