我正在使用Restful API開發Google Drive API。使用JSON對Java多部分文件進行上傳
我需要上傳文件和json正文。
但是，當我嘗試上傳與我的java代碼，我遇到了谷歌驅動器的錯誤代碼。
==>無效多跟0 MIME部分
請求這裏是谷歌驅動器的導向件。 enter image description here
這是我的代碼。 我的代碼有什麼問題？
public int uploadFileToGoogleDrive(File file, Long acctId, String
accessToken, JSONObject json) {
HttpClient httpClient = new HttpClient();
PostMethod method = null;
Integer result = -1;
String boundary = "---------------------------" + System.currentTimeMillis();
try {
method = new PostMethod("https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart");
method.setRequestHeader("Authorization", "Bearer " + accessToken);
method.setRequestHeader("Content-Type", "multipart/related; boundary=" + boundary);
Part[] parts = {new StringPart("",json.toString(),"utf-8"), new FilePart(file.getName(), file, null, "utf-8")};
//MultipartRequestEntity multipartRequestEntity = new MultipartRequestEntity(parts, method.getParams());
method.setRequestEntity(new MultipartRequestEntity(parts, method.getParams()));
httpClient.getHttpConnectionManager().closeIdleConnections(0);
result = httpClient.executeMethod(method);
if (result == HttpStatus.SC_OK) {
InputStream rstream = null;
rstream = method.getResponseBodyAsStream();
BufferedReader br = new BufferedReader(
new InputStreamReader(rstream));
String line;
while ((line = br.readLine()) != null) {
resultString += line;
}
}
System.out.println("##############################################\n" + json.toString() + "\n##############################################");
logger.debug(resultString);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
logger.error(e.getMessage(), e);
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
logger.error(e.getMessage(), e);
}
catch (ProtocolException e) {
// TODO Auto-generated catch block
logger.error(e.getMessage(), e);
}
catch (IOException e) {
// TODO Auto-generated catch block
logger.error(e.getMessage(), e);
}finally {
method.releaseConnection();
}
return result;
}
}
