序言

如果您认为这可能与Using iOS Dropbox SDK to do a Chunked Upload of Core Data重复，那么我不得不让您失望 - 我的问题不在于如何进行上传。相反，我的问题是比较两种上传方法的优缺点。其他问题没有涉及，所以我的问题不重复。

问题：

对于使用DropboxSDK上传文件，有两种方法可用于两种不同的方法。评论只说一种方法更适合大于几兆字节的文件＆＃34;。有什么具体的好处？第二种方法似乎更难以使用，它提供了哪些优势？

以下是iOS DropboxSDK中的两种方法：

1。 uploadFile:

/* Uploads a file that will be named filename to the given path on the server. sourcePath is the`
   full path of the file you want to upload. If you are modifying a file, parentRev represents the
   rev of the file before you modified it as returned from the server. If you are uploading a new
   file set parentRev to nil. */
- (void)uploadFile:(NSString *)filename toPath:(NSString *)path withParentRev:(NSString *)parentRev
    fromPath:(NSString *)sourcePath;

2。 uploadFileChunk:

/* These calls allow you to upload files in chunks, which is better for file larger than a few megabytes.
   You can append bytes to the file using -[DBRestClient uploadFileChunk:offset:uploadId:] and then call
   -[DBRestClient uploadFile:toPath:withParentRev:fromUploadId:] to turn the bytes appended at that uploadId
   into an actual file in the user's Dropbox.
   Use a nil uploadId to start uploading a new file. */
- (void)uploadFileChunk:(NSString *)uploadId offset:(unsigned long long)offset fromPath:(NSString *)localPath;

请参阅https://www.dropbox.com/developers/core/docs#files_put和https://www.dropbox.com/developers/core/docs#chunked-upload。

前者允许最多150MB并将文件写入单个HTTP请求中，因此无法在不从文件开头重新开始的情况下恢复失败的上载。

后者允许任何大小，任何失败的上传都可以在中断的地方恢复（只需发送下一个块）。

DropboxSDK：上传文件块的好处是：上传文件：在RestClient中？
