Question

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term=petrol，则代码可以正常工作，例如但如果我添加两个术语，例如term=petrol+fuel，则会开始给我错误{"error": {"text": "Signature was invalid", "id": "INVALID_SIGNATURE", "description": "Invalid signature

此代码有什么问题？

SAMPLE API REQUEST

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

iTS包含一个+但是当我使用+时它会给我上面的错误

Answer 1

我使用UTF8编码编码了字符串，现在运行良好

在yelp url中传递两个术语时签名无效
