我正在尝试进行 yelp 查询并使用 OAuth Lib

这是代码

  NSURL *URL = [NSURL URLWithString:[NSString stringWithFormat:@"http://api.yelp.com/v2/search?term=petrol+restaurants&ll=%f,%f&radius_filter=300",coordinate.latitude,coordinate.longitude]];

  OAConsumer *consumer = [[OAConsumer alloc] initWithKey:consumerKey secret:consumerSecret];
  OAToken *token = [[OAToken alloc] initWithKey:tokenUrl secret:tokenSecret];

  id<OASignatureProviding, NSObject> provider = [[OAHMAC_SHA1SignatureProvider alloc] init];
  NSString *realm = nil;

  OAMutableURLRequest *request = [[OAMutableURLRequest alloc] initWithURL:URL
                                                                 consumer:consumer
                                                                    token:token
                                                                    realm:realm
                                                        signatureProvider:provider];
  [request prepare];

  NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
  connection = nil;

如果查询有一个术语，则代码可以完美运行，term=petrol例如但是如果我添加两个术语，就像term=petrol+fuel它开始给我错误一样{"error": {"text": "Signature was invalid", "id": "INVALID_SIGNATURE", "description": "Invalid signature

这段代码有什么问题？

示例 API 请求

http://api.yelp.com/v2/search?term=cream+puffs&location=San+Francisco

iTS 包含一个 + 但当我使用 + 时，它给了我以上错误

我用 UTF8 编码对字符串进行了编码，现在运行良好
