iphone - -[GTMHTTPUploadFetcher connectionDidFinishLoading :] 中的断言失败

Question

我正在尝试使用适用于 Objective-C 的 Google API 客户端库在 youtube 上上传视频，我使用下面给出的代码，但它一直给我这个错误，我试图再次在 youtube 示例项目上运行我的帐户，它给出了同样的错误。

谁能指导我哪里出了问题。我在服务页面上检查了 YouTube Data API v3。

*** Assertion failure in -[GTMHTTPUploadFetcher connectionDidFinishLoading:], /Volumes/data/Work/test/DLNew/DL/google-api-objectivec-client-read-only/Source/HTTPFetcher/GTMHTTPUploadFetcher.m:399
2013-08-30 14:28:31.399 [1250:907] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'unexpected response data (uploading to the wrong URL?)'

我检查了 GTMHTTPUploadFetcher 类的代码，它正在使此链接上的应用程序崩溃

`#if DEBUG
  // The initial response of the resumable upload protocol should have an
  // empty body
  //
  // This assert typically happens because the upload create/edit link URL was
  // not supplied with the request, and the server is thus expecting a non-
  // resumable request/response.
  NSAssert([[self downloadedData] length] == 0,
                    @"unexpected response data (uploading to the wrong URL?)");
 #endif

问题是我从一个新的 gmail 帐户登录，所以我需要登录 youtube 站点并需要创建一个 channel ，然后才能将视频上传到 youtube。所以现在我可以在创建 youtube channel 后上传视频。但是我如何为其他用户处理这种情况，任何想法

我遇到了同样的崩溃并找到了解决方案。如果底层请求是错误请求但未明确提供响应信息(我的授权方有效并使用方法 canAuthorize 通过检查，如 Ryan_IRL 指出)，客户端似乎也会发生此崩溃。

查看库后，我发现设置预处理器宏 STRIP_GTM_FETCH_LOGGING并为 HTTPFetcher 启用日志记录代码中的某处

#if STRIP_GTM_FETCH_LOGGING
[GTMHTTPFetcher setLoggingEnabled:YES];
#endif

日志存储在 GTMHTTPDebugLogs 中模拟器内的文件夹(类似于 /Users/<username>/Library/Application Support/iPhone Simulator/6.1/Applications/65451CDB-27D6-4BE2-910C-7F22D6A01832/GTMHTTPDebugLogs )。您可以在那里找到 HTML 格式的完整日志 (...)。

单击“请求/响应日志”，在我的案例中显示了以下日志。

Response body: (201 bytes)
{
  "id" : "gtl_1",
  "error" : {
    "message" : "Bad Request",
    "code" : -32602,
    "data" : [
      {
        "domain" : "youtube.video",
        "reason" : "invalidTitle",
        "locationType" : "other",
        "location" : "body.snippet.title",
        "message" : "Bad Request"
      }
    ]
  }
}

错误的请求与(要上传的视频的)标题有关，其中包含一些禁止使用的字符。修复标题解决了崩溃问题，视频已正确上传。在这种情况下状态 200 当然是......令人沮丧并且显然是错误的。

我也对 GTM 库以及在这种情况下使用 NSAssert 感到非常失望。
