我认为TDOAuth是最好的解决方案。它干净简单,只有一个 .h 和 .m 文件可以使用,没有复杂的示例项目..
这是 OAuth 1.0 流程:
第 1 步 - 获取请求令牌
//withings additional params
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
[dict setObject:CALL_BACK_URL forKey:@"oauth_callback"];
//init request
NSURLRequest *rq = [TDOAuth URLRequestForPath:@"/request_token" GETParameters:dict scheme:@"https" host:@"oauth.withings.com/account" consumerKey:WITHINGS_OAUTH_KEY consumerSecret:WITHINGS_OAUTH_SECRET accessToken:nil tokenSecret:nil];
//fire request
NSURLResponse* response;
NSError* error = nil;
NSData* result = [NSURLConnection sendSynchronousRequest:rq returningResponse:&response error:&error];
NSString *s = [[NSString alloc] initWithData:result encoding:NSUTF8StringEncoding];
//parse result
NSMutableDictionary *params = [NSMutableDictionary dictionary];
NSArray *split = [s componentsSeparatedByString:@"&"];
for (NSString *str in split){
NSArray *split2 = [str componentsSeparatedByString:@"="];
[params setObject:split2[1] forKey:split2[0]];
}
token = params[@"oauth_token"];
tokenSecret = params[@"oauth_token_secret"];
第 2 步 - 获取授权令牌(通过在 UIWebView 中加载请求,webViewDidFinishLoad 委托方法将处理回调..)
//withings additional params
NSMutableDictionary *dict2 = [NSMutableDictionary dictionary];
[dict setObject:CALL_BACK_URL forKey:@"oauth_callback"];
//init request
NSURLRequest *rq2 = [TDOAuth URLRequestForPath:@"/authorize" GETParameters:dict2 scheme:@"https" host:@"oauth.withings.com/account" consumerKey:WITHINGS_OAUTH_KEY consumerSecret:WITHINGS_OAUTH_SECRET accessToken:token tokenSecret:tokenSecret];
webView.delegate = self;
[DBLoaderHUD showDBLoaderInView:webView];
[webView loadRequest:rq2];
按如下方式处理 webView 以启动第 3 步(我知道 isAuthorizeCallBack 闻起来很臭,但它可以完成工作,应该重构它..)
- (void)webViewDidFinishLoad:(UIWebView *)aWebView
{
[DBLoaderHUD hideDBLoaderInView:webView];
NSString *userId = [self isAuthorizeCallBack];
if (userId) {
//step 3 - get access token
[DBLoaderHUD showDBLoaderInView:self.view];
[self getAccessTokenForUserId:userId];
}
//ugly patchup to fix an invalid token bug
if ([webView.request.URL.absoluteString isEqualToString:@"http://oauth.withings.com/account/authorize?"])
[self startOAuthFlow];
}
- (NSString *)isAuthorizeCallBack
{
NSString *fullUrlString = webView.request.URL.absoluteString;
if (!fullUrlString)
return nil;
NSArray *arr = [fullUrlString componentsSeparatedByString:@"?"];
if (!arr || arr.count!=2)
return nil;
if (![arr[0] isEqualToString:CALL_BACK_URL])
return nil;
NSString *resultString = arr[1];
NSArray *arr2 = [resultString componentsSeparatedByString:@"&"];
if (!arr2 || arr2.count!=3)
return nil;
NSString *userCred = arr2[0];
NSArray *arr3 = [userCred componentsSeparatedByString:@"="];
if (!arr3 || arr3.count!=2)
return nil;
if (![arr3[0] isEqualToString:@"userid"])
return nil;
return arr3[1];
}
- (void)startOAuthFlow
{
[self step1];
[self step2];
}
最后 - 第 3 步 - 获取访问令牌
- (void)getAccessTokenForUserId:(NSString *)userId
{
//step 3 - get access token
//withings additional params
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
[dict setObject:CALL_BACK_URL forKey:@"oauth_callback"];
[dict setObject:userId forKey:@"userid"];
//init request
NSURLRequest *rq = [TDOAuth URLRequestForPath:@"/access_token" GETParameters:dict scheme:@"https" host:@"oauth.withings.com/account" consumerKey:WITHINGS_OAUTH_KEY consumerSecret:WITHINGS_OAUTH_SECRET accessToken:token tokenSecret:tokenSecret];
//fire request
NSURLResponse* response;
NSError* error = nil;
NSData* result = [NSURLConnection sendSynchronousRequest:rq returningResponse:&response error:&error];
NSString *s = [[NSString alloc] initWithData:result encoding:NSUTF8StringEncoding];
//parse result
NSMutableDictionary *params = [NSMutableDictionary dictionary];
NSArray *split = [s componentsSeparatedByString:@"&"];
for (NSString *str in split){
NSArray *split2 = [str componentsSeparatedByString:@"="];
[params setObject:split2[1] forKey:split2[0]];
}
[self finishedAthourizationProcessWithUserId:userId AccessToken:params[@"oauth_token"] AccessTokenSecret:params[@"oauth_token_secret"]];
}
