我们正在使用 apex 将文件上传到 Google Drive 的文件夹，并提供文件夹 ID 并发送请求。调试http请求后，我们可以看到请求良好并且获取的文件夹ID是正确的。但文件未上传到文件夹内部，而是上传到文件夹外部和驱动器内部其他位置。请帮助我们了解错误。无法理解问题出在哪里。
这是代码。 `
String boundary = '----------9889464542212';
String delimiter = '\r\n--' + boundary +'\r\n';
String close_delim = '\r\n--' + boundary + '--';
String bodyEncoded = EncodingUtil.base64Encode(att.Body);
String FolderId= '1U0vuP53dpIAM_WlmbJfvwvMCK0XZREOo';
String body=delimiter+'Content-Type: application/pdf\r\n\r\n'+'{ "title" : "'+ filename+'",'+' "mimeType" : "' + att.ContentType+ '",'+ '"parents":[{"id":"'+ FolderId +'"}] }' + delimiter+'Content-Type: ' + att.ContentType +'\nContent-Transfer-Encoding: base64\r\n'+'\r\n'+ '\r\n'+bodyEncoded+close_delim;
`
这是请求:`------------9889464542212 内容类型:应用程序/pdf
{ "title": "tester 83_Resume", "mimeType": "application/pdf","parents":[{"id":"1U0vuP53dpIAM_WlmbJfvwvMCK0XZREOo"}] } ------------9889464542212 内容类型:应用程序/pdf 内容传输编码:base64 `

最佳答案
遇到了同样的问题。它已上传到根驱动器目录，而不是您提供的父目录。它看起来像你的 parents content json is allright 。看起来您正在使用分段上传，这可能存在问题。下面在 Android 上使用 okhttp3 生成的基本请求似乎可以正常工作。这是一个简单的基本请求，没有使用任何库。
工作要求:
POST https://www.googleapis.com/upload/drive/v2/files?uploadType=multipart
Accept: application/json
Content-Type: multipart/related
Authorization: Bearer ya29.c.El__BV-q0dMeaVNil2kcVYUkpZmeEW85rjV6hRdgsoIeXbl-pFeEAaJuqcUSwok63JcnKg

用于生成请求的 Java android 代码 ( okhttp 3.10.0 ):
String fileMimeType = "image/jpeg";
String metaDataFile = "{\"title\":\"" + filename + "\"," +
"\"mimeType\":\"" + fileMimeType + "\"," +
"\"description\":\"" +account.getName() + " uploaded " + filename + "\"," +
"\"parents\":[{\"id\":\"" + account.getUploadFolderID() + "\"}]" +
"}";
RequestBody requestBodyMetaData = RequestBody.create(JSON, metaDataFile);
RequestBody requestBodyFile = RequestBody.create(fileMimeType, BitmapUtils.getBase64(sourceFile));
MultipartBody.Part requestBodyFilePart = MultipartBody.Part.create(Headers.of("Content-Disposition", "form-data; name=\"file\"", "Content-Transfer-Encoding", "base64"), requestBodyFile);
RequestBody requestBodyMultipart = new MultipartBody.Builder("hkj_multipart_data")
.setType(MultipartBody.FORM)
.addFormDataPart("metadata", null, requestBodyMetaData)
.addPart(requestBodyFilePart)
.build();
request = new Request.Builder()
.url(HKJConstants.GOOGLE_UPLOAD_API_SERVER_BASE_URL + "files?uploadType=multipart")
.header("Accept", "application/json")
.header("Content-Type", "multipart/related")
.addHeader("Authorization", "Bearer " + accessToken)
.post(requestBodyMultipart)
.build();
Call call = okHttpClient.newCall(request);
Response response = call.execute();
if (response.isSuccessful()) {
GoogleDriveFileList googleDriveFileListResult = new Gson().fromJson(response.body().charStream(), GoogleDriveFileList.class);
if(googleDriveFileListResult.IsFilled()){
return true;
}
}
关于java - 尝试将文件上传到 Google 云端硬盘的特定文件夹。尽管 http 请求具有正确的文件夹 ID，但它还是被上传到文件夹之外，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48299734/
