ios - 为上传的内容(Google Drive、iOS)提供了无效的 MIME 类型
<p><p>我正在尝试使用 <a href="https://developers.google.com/drive/v2/reference/files/insert" rel="noreferrer noopener nofollow">files.insert</a> 创建一个 CSV 文件到 Google Drive .不幸的是，我遇到了 2 个问题。请帮我解决它。</p>
<p>我的项目信息:</p>
<ul>
<li><p>语言:Objective-C</p></li>
<li><p>Pod:GoogleAPIClientForREST/Drive</p></li>
</ul>
<p>1/我在框架中找不到 <code>files.insert</code>。所以，我使用 <code>files.create</code>。我说的对吗？</p>
<p>2/</p>
<blockquote>
<p>Accepted Media MIME types: */*</p>
</blockquote>
<p>当我使用 mimeType:'text/csv' 时它工作正常。但它看起来像这样:</p>
<p> <a href="/image/gFwC3.png" rel="noreferrer noopener nofollow"><img src="/image/gFwC3.png" alt="CSV-file in google Drive with 'text/csv'"/></a> </p>
<p>而且，我需要这样的东西来确保客户要求和易于编辑</p>
<p> <a href="/image/09ElN.png" rel="noreferrer noopener nofollow"><img src="/image/09ElN.png" alt="CSV-file in google Drive with 'application/vnd.google-apps.spreadsheet'"/></a> </p>
<p>所以，我将 mimeType 更改为“application/vnd.google-apps.spreadsheet”。这让我犯了一个错误:</p>
<pre><code>An error occurred: Error Domain=com.google.GTLRErrorObjectDomain Code=400 "(Invalid MIME type provided for the uploaded content.)" UserInfo={error=Invalid MIME type provided for the uploaded content., GTLRStructuredError=GTLRErrorObject 0x7fc77c808840: {message:"Invalid MIME type provided for the uploaded content." errors: code:400}, NSLocalizedFailureReason=(Invalid MIME type provided for the uploaded content.)}
</code></pre>
<p>这是我的代码:</p>
<pre><code>GTLRDrive_File *metadata = ;
metadata.name = @"export.csv";
NSString *content = @"a,b,c\nx,y,z";
NSData *data = ;
GTLRUploadParameters *uploadParameters = ;
GTLRDriveQuery_FilesCreate *query = [GTLRDriveQuery_FilesCreate queryWithObject:metadata
uploadParameters:uploadParameters];
[self.service executeQuery:query completionHandler:^(GTLRServiceTicket *ticket,
GTLRDrive_File *updatedFile,
NSError *error) {
}];
</code></pre>
<p>此代码有时可以与我的谷歌帐户一起使用，并且 GTLRDriveQuery_FilesUpdate 运行良好!</p>
<pre><code>File GTLRDrive_File 0x7fee0587b970: {mimeType:"application/vnd.google-apps.spreadsheet" id:"..." kind:"drive#file" name:"export.csv"}
</code></pre></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>对我有用的是在上传参数中设置“源”mime 类型，并在文件对象中设置“目标”mime 类型:</p>
<pre><code>NSData *data = ;
NSString *mimeType = @"text/csv";
NSString *convertToMimeType = @"application/vnd.google-apps.spreadsheet";
GTLRDrive_File *newFile = ;
newFile.name = fileName;
if (convertToMimeType != nil) newFile.mimeType = convertToMimeType;
if (parentItem != nil) newFile.parents = ;
GTLRUploadParameters *uploadParameters = ;
GTLRDriveQuery_FilesCreate *query = ;
</code></pre></p>
