直到昨天我还有工作代码，今天我在com.google.gdata.util.ResourceNotFoundException 从我的 gae 代码中读取谷歌文档时看到了异常，如下所示。请注意，最后一行抛出此异常。
DocsService client = new DocsService("sakshum-YourAppName-v1");
client.setOAuthCredentials(oauthParameters,
new OAuthHmacSha1Signer());
URL feedUrl = new URL(
"https://docs.google.com/feeds/default/private/full/");
DocumentQuery dquery = new DocumentQuery(feedUrl);
dquery.setTitleQuery(title);
dquery.setTitleExact(true);
dquery.setMaxResults(10);
DocumentListFeed resultFeed = client.getFeed(dquery,
DocumentListFeed.class);
log.info("feed size:" + resultFeed.getEntries().size());
if (resultFeed.getEntries().size() != 1) {
log.info("More than one document is found with same title.");
return null;
}
emailBody = new StringBuffer("");
for (DocumentListEntry entry : resultFeed.getEntries()) {
String docId = entry.getDocId();
String docType = entry.getType();
log.info("Getting doc from url with docId:" + docId
+ " docType:" + docType);
URL exportUrl = new URL(
"https://docs.google.com/feeds/download/" + docType
+ "s/Export?docID=" + docId
+ "&exportFormat=html");
MediaContent mc = new MediaContent();
mc.setUri(exportUrl.toString());
log.info("Getting media");
MediaSource ms = client.getMedia(mc);
详细的堆栈跟踪：
