IOS HTTP请求示例

Question

我正在尝试调用fitbit API.我不确定如何将下面显示的HTTP请求输入到我的Objective C代码中,以便进行此调用并处理响应.

POST /oauth/request_token HTTP/1.1
Host: api.fitbit.com
Authorization: OAuth oauth_consumer_key="fitbit-example-client-application",
oauth_signature_method="HMAC-SHA1",
oauth_timestamp="1270248082",
oauth_nonce="161822064",
oauth_callback="http%3A%2F%2Fexample.fitbit.com%2Fapp%2FcompleteAuthorization",
oauth_signature="Omf%2Bls2gn%2BDlghq245LRIyfMdd8%3D"
oauth_version="1.0"

一个简单的例子会有所帮助.谢谢.

我建议使用 OAuth 库来处理 OAuth 签名生成。争论授权标头可能会很痛苦。我已经成功使用了oauthconsumer 。

代码示例：

OAConsumer *consumer = [[OAConsumer alloc] initWithKey:oauthConsumerKey secret:oauthConsumerSecret];
OAToken *token = [[OAToken alloc] initWithKey:oauthAccessToken secret:oauthAccessTokenSecret];
OAHMAC_SHA1SignatureProvider *provider = [[OAHMAC_SHA1SignatureProvider alloc] init];

OAMutableURLRequest *request = [[OAMutableURLRequest alloc] initWithURL:[NSURL URLWithString:urlString] consumer:consumer token:token realm:nil signatureProvider:provider];
[request prepare];

NSHTTPURLResponse *response = nil;
NSError *error = nil;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

在此示例中，您将提供的 5 个字符串是：

oauthConsumerKey
oauthConsumerSecret
oauthAccessToken
oauthAccessTokenSecret
urlString
