当我预先形成文件时,Google驱动器v2会默认返回完整的文件资源。获取。但是,当我针对V3发出相同的请求时,即使文档声明它应该返回文件资源,它也只返回部分文件资源。
GET /drive/v2/files/0B5pJkOVaKccEVEsybFA2WjJjQ1k?access_token={Token}
返回完整档案

然而,当我对V3提出相同的请求时
GET /drive/v3/files/0B5pJkOVaKccEVEsybFA2WjJjQ1k?access_token={Token}
仅返回部分元数据
{
"mimeType": "text/plain",
"kind": "drive#file",
"id": "0B5pJkOVaKccEVEsybFA2WjJjQ1k",
"name": "deleteme.txt"
}
我发现通过添加fields参数,我可以从V3请求其他参数。但是我无法找到一种方法来在一个请求中返回所有字段。
fields
选择器指定要包含在其中的字段子集 响应。
有关详细信息,请参阅部分响应部分 在性能提示文档中。用于提高性能。
它的一个get请求所以我不关心性能我只需要查看该文件的所有数据。
答案 0 :(得分:19)
在文档中挖掘后,我设法找到comment。
如果需要,请在字段选择中使用通配符 例如:fields = items / pagemap / *选择页面映射中的所有对象。
所以我试过了。
GET /drive/v3/files/0B5pJkOVaKccEVEsybFA2WjJjQ1k?access_token={Token}&fields=*
果然它返回了完整的文件资源。
解决方案是将fields=*
添加到请求中。我个人认为这应该是默认的。
