ios – 云存储服务,什么,如何以及哪些？

它告诉您这个包装器库是基于底层JSON API自动生成的.因此,所有GTLStorage …类都将模仿Google Storage的JSON API.执行实际API调用的类是GTLQueryStorage.

如果查看该JSON文档,您会发现有一个用于将数据存储到存储桶中的对象：https://developers.google.com/storage/docs/json_api/v1/#Objects
上传新对象的方法是“插入”

回到GTLQueryStorage.h文件,您将找到相应的Objective-C方法将新对象插入到存储桶中：

// Method: storage.objects.insert
// Stores new data blobs and associated Metadata.
//  required:
//   bucket: Name of the bucket in which to store the new object. Overrides the
//     provided object Metadata's bucket value,if any.
//  Optional:
//   ifGenerationMatch: Makes the operation conditional on whether the object's
//     current generation matches the given value.
//   ifGenerationNotMatch: Makes the operation conditional on whether the
//     object's current generation does not match the given value.
//   ifMetagenerationMatch: Makes the operation conditional on whether the
//     object's current Metageneration matches the given value.
//   ifMetagenerationNotMatch: Makes the operation conditional on whether the 
//     object's current Metageneration does not match the given value.
//   name: Name of the object. required when the object Metadata is not
//     otherwise provided. Overrides the object Metadata's name value,if any.
//   projection: Set of properties to return. Defaults to noAcl,unless the
//     object resource specifies the acl property,when it defaults to full.
//      kGTLStorageProjectionFull: Include all properties.
//      kGTLStorageProjectionNoAcl: Omit the acl property.
//  Upload Parameters:
//   Accepted MIME type(s): */*
//  Authorization scope(s):
//   kGTLAuthScopeStorageDevstorageFullControl
//   kGTLAuthScopeStorageDevstorageReadWrite
// Fetches a GTLStorageObject.
+ (id)queryForObjectsInsertWithObject:(GTLStorageObject *)object
                           bucket:(NSString *)bucket
                 uploadParameters:(GTLUploadParameters *)uploadParametersOrNil;

所以你应该：

>分配GTLserviceStorage的实例>将API密钥设置为该对象>使用上面的类方法为要使用正确存储桶保存的对象实例化GTLQueryStorage对象>创建一个服务票据,它执行查询并获得一个完成处理程序来处理完成(成功,错误情况).
