Google Drive API V3（javascript）更新文件内容 [英] Google Drive API V3 (javascript) update file contents

问题描述

我想使用Google Drive API V3更新Google文档的内容（javascript）：
$ b https://developers.google.com/drive/v3/reference/files/update

我可以更新文件元数据（例如名称），但文档不包含实际文件内容的补丁语义。有没有办法在 gapi.client.drive.files.update JSON.stringify（）值作为参数

  var request = gapi.client.drive.files.update（{
'fileId' ：fileId，
'name'：'更新文件名'，
'uploadType'：'media'，
'mimeType'：'application / vnd.google-apps.document'
}）; 
 
 var fulfilledCallback = function（fulfilled）{
 console.log（Update fulfilled！，fulfilled）; 
}; 
 var rejectedCallback =函数（拒绝）{
 console.log（拒绝更新！，拒绝）; 
}; 
 
 request.then（fulfilledCallback，rejectedCallback）
  

解决方案 div>

有两个问题：

1. JavaScript客户端库不支持媒体上传。


2. Google文件没有原生文件格式。

您可以通过编写自己的文件来解决问题＃1上传功能构建在XHR之上。下面的代码应该适用于大多数现代Web浏览器：

  function updateFileContent（fileId，contentBlob，callback）{
 var xhr = new XMLHttpRequest（）; 
 xhr.responseType ='json'; 
 xhr.onreadystatechange = function（）{
 if（xhr.readyState！= XMLHttpRequest.DONE）{
 return; 
} 
 callback（xhr.response）; 
}; 
 xhr.open（'PATCH'，'https://www.googleapis.com/upload/drive/v3/files/'+ fileId +'？uploadType = media'）; 
 xhr.setRequestHeader（'Authorization'，'Bearer'+ gapi.auth.getToken（）。access_token）; 
 xhr.send（contentBlob）; 
 
 $ / code> 

要解决问题＃2，您可以向Google云端硬盘发送文件类型可以从.txt，.docx等导入。以下代码使用上述功能以纯文本格式更新Google文档的内容：

  function run（）{
 var docId ='...'; 
 var content ='Hello World'; 
 var contentBlob = new Blob（[content]，{
'type'：'text / plain'
}）; 
 updateFileContent（fileId，contentBlob，function（response）{
 console.log（response）; 
}）; 
} 
  




I want to update the contents of a Google doc using the Google Drive API V3 (javascript):

https://developers.google.com/drive/v3/reference/files/update

I'm able to update the file metadata (such as the name) but the documentation doesn't include patch semantics for the actual file content. Is there a way to pass a JSON.stringify() value as a param in the gapi.client.drive.files.update request:

var request = gapi.client.drive.files.update({
    'fileId': fileId,
    'name' : 'Updated File Name',
    'uploadType': 'media',
    'mimeType' : 'application/vnd.google-apps.document'
  });

var fulfilledCallback = function(fulfilled) { 
    console.log("Update fulfilled!", fulfilled);
};
var rejectedCallback = function(rejected) { 
    console.log("Update rejected!", rejected);
};

request.then(fulfilledCallback, rejectedCallback)

解决方案

There are two issues:

1. The JavaScript client library doesn't support media upload.
2. Google Docs files don't have a native file format.

You can work around issue #1 by writing your own upload functionality built on top of XHR. The following code should work on most modern web browsers:

function updateFileContent(fileId, contentBlob, callback) {
  var xhr = new XMLHttpRequest();
  xhr.responseType = 'json';
  xhr.onreadystatechange = function() {
    if (xhr.readyState != XMLHttpRequest.DONE) {
      return;
    }
    callback(xhr.response);
  };
  xhr.open('PATCH', 'https://www.googleapis.com/upload/drive/v3/files/' + fileId + '?uploadType=media');
  xhr.setRequestHeader('Authorization', 'Bearer ' + gapi.auth.getToken().access_token);
  xhr.send(contentBlob);
}

To work around issue #2 you can send Drive a file type that Google Docs can import from, such .txt, .docx, etc. The following code uses the function above to update the content of a Google Doc using plain text:

function run() {
  var docId = '...';
  var content = 'Hello World';
  var contentBlob = new  Blob([content], {
    'type': 'text/plain'
  });
  updateFileContent(fileId, contentBlob, function(response) {
    console.log(response);
  });
}
