React-原生Google Drive如何获取文件和文件夹列表

Question

我已经在我的项目中使用了react-native-google- drive -api-wrapper，我可以成功登录并创建文件和文件夹，但我无法列出存储在我的驱动器中的文件。我正在使用这个链接中给出的react-native-google-drive-api-wrapper -- https://www.npmjs.com/package/react-native-google-drive-api-wrapper，来获取文件和文件夹的列表，上面链接中提到的代码是：

     GDrive.files.list({q: "'root' in parents"});

我的代码是：

     GDrive.files.list({q: "'root' in parents"})
             .then(response =>{ alert("response is "+JSON.stringify(response))
                  console.log(response.url)                      
            })
             .catch(er=> alert("error is" +er));

我得到的回答是，

     ty-policy":"frame-ancestors 'self'","content-type":"application/json; charset=UT

我该如何获取存储在Google Drive中的所有文件的列表。

Answer 1

我解决了。我认为这只是JSON.stringify(响应)和res.json()的区别。不管怎样，你可以使用下面的代码

    GDrive.files.list({
              q: "'root' in parents",
             })
              .then(res=>res.json())
              .then(data=>alert(data.files[1].name)) //data.files is the array containing list of files 
              .catch(err=>console.log(err))

多亏了https://github.com/RobinBobin/react-native-google-drive-api-wrapper/issues/19#issue-571412310，我复制了他获取数据的方式。
