ios - Youtube API iOS : Request failed: bad request (400)
<p><p>我正在开发一个需要获取 youtubechannel 并订阅它的 iOS 应用程序。
我可以获得没有 OAuth2 的 channel 列表，但要订阅它，我需要通过 OAuth2 标准获取访问 token 。 </p>
<p>我可以通过一些手工获得访问 token 。但是，当我将此 token 发送到 header 并请求正文进行订阅时，它会给我“错误请求(400)”错误。</p>
<h2>发送请求代码</h2>
<pre><code>NSString *URLString = "];
AFHTTPRequestOperationManager *manager = ;
AFHTTPRequestSerializer *requestSerializer = ;
] forHTTPHeaderField:@"Authorization"];
;
manager.requestSerializer = requestSerializer;
NSDictionary *parameters = @{@"snippet":@{
@"resourceId":@{
@"channelId":[[ valueForKey:@"snippet"] valueForKey:@"channelId"],
@"kind":@"youtube#channel"
}
}
};
[manager POST:URLString parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"response ; %@",responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"failed");
}];
}
</code></pre>

<p><p>我发现了问题。有两个错误。</p>
<ol>
<li><p>其实我是在设置不同的requestSerializer，传递不同的序列化器。</p></li>
<li><p>我正在将 APIKey 传递给 url 进行订阅，但不需要传递它。</p></li>
</ol>
<p><strong>我的新代码是</strong></p>
<pre><code> NSString *URLString = ;
AFHTTPRequestOperationManager *manager = ;
AFHTTPRequestSerializer *requestSerializer = ;
] forHTTPHeaderField:@"Authorization"];
;
manager.requestSerializer = requestSerializer;
