Google Drive可恢復文件上傳問題，使用JavaScript API

我試圖將Google Drive可恢復文件上傳/更新與我的應用程序集成。但是，當我更新文件時，文件正在以編碼格式進行更新，它並未採取實際內容。編碼格式適用於分段uploadType，但相同內容不適用於可恢復上傳。請找到下面的細節Google Drive可恢復文件上傳問題，使用JavaScript API

步驟1：此處開始可恢復會話

function uploadFile(fileData) { 

    var accessToken = 'ya29.nwI5Em6UnYGHvVzVx7lBk5tD-xzFl4_JG3_c-_t4FJ3owll_8i_rL5M17LFV6VlF7QE'; 

    const boundary = '-------314159265358979323846'; 
    const delimiter = "\r\n--" + boundary + "\r\n"; 
    const close_delim = "\r\n--" + boundary + "--"; 

    var contentType = fileData.type || 'application/octet-stream'; 
    var metadata = { 
      'name': fileData.name, 
      'mimeType': contentType, 
      'Content-Type': contentType, 
      'Content-Length': fileData.size 
     }; 

    var request = gapi.client.request({ 
     'path' : 'upload/drive/v3/files', 
     'method' : 'POST', 
     'params' : {'uploadType':'resumable'}, 
     'headers' : { 
      'X-Upload-Content-Type' : fileData.type, 
      'Content-Type': 'application/json; charset=UTF-8', 
      'Authorization': 'Bearer ' + accessToken, 
     }, 
     'body' : metadata 
    }); 

    request.execute(function(resp, raw_resp) { 
     var locationUrl = JSON.parse(raw_resp).gapiRequest.data.headers.location; 
     console.log(locationUrl); 
     uploadToLocationUrl(locationUrl, fileData); 
    }); 
}

高達它的優良我越來越位置URL，然後調用上傳文件的功能。

步驟2：可恢復的會話發起請求

 function uploadToLocationUrl(locationUrl, fileData) 
     { 
      var reader = new FileReader(); 
      reader.readAsBinaryString(fileData); 
      reader.onload = function (e) { 
      var contentType = fileData.type || 'application/octet-stream'; 
      var metadata = { 
       'name': fileData.name, 
       'mimeType': contentType, 
       'Content-Type': contentType, 
       'Content-Length': fileData.size 
      }; 

       var base64Data = btoa(reader.result); 
       var multipartRequestBody = 
        delimiter + 
        'Content-Type: application/json\r\n\r\n' + 
        JSON.stringify(metadata) + 
        delimiter + 
        'Content-Type: ' + contentType + '\r\n' + 
        'Content-Transfer-Encoding: base64\r\n' + 
        '\r\n' + 
        base64Data + 
        close_delim; 

      var requestPost = gapi.client.request({ 
       'path' : locationUrl, 
       'method' : 'PUT', 
       'headers' : { 
        'X-Upload-Content-Length' : fileData.size 
       }, 
       'body' : multipartRequestBody 
       }); 
      console.log(requestPost); 

      requestPost.execute(function(resp, raw_resp) { 
       console.log(resp); 
      }); 
     } 
}

結果：谷歌更新的文件驅動

{"name":"api.txt","mimeType":"text/plain"}

抱歉延遲答案，

你只需要改變uploadToLocationUrl功能代碼

找到更新的代碼下面，

function uploadToLocationUrl(locationUrl, fileData,arrayBuffer) 
    { 


     var contentType = fileData.type || 'application/octet-stream'; 

     var requestPost = gapi.client.request({ 
      'path' : locationUrl, 
      'method' : 'PUT', 
      'headers' : { 
       'Content-Type': contentType, 
       "Content-Length": arrayBuffer.byteLength, 

      }, 
      'data' : arrayBuffer 
      }); 
     console.log(requestPost); 

     requestPost.execute(function(resp, raw_resp) { 
      console.log(resp); 
     }); 



    }

您無需重新發送元，只是字節數組很好。
