Question

我目前正在使用Java中的Google Contact API实施Contact Application。我已经完成了联系人的单独添加，删除和更新。现在，我正在对联系人实施批处理操作。

我已经创建了XML文件，该文件需要作为批处理操作的请求主体发送。以下是我创建的请求的正文

<?xml version="1.0" encoding="UTF-8"?>
<feed
    xmlns="http://www.w3.org/2005/Atom"
    xmlns:batch="http://schemas.google.com/gdata/batch"

当我将上述XML作为 POST 请求的正文发送到URI

https://www.google.com/m8/feeds/contacts/default/full/batch

在OAuth Playground和Postman中，我得到了有效的答复。

但是当我在Java代码中将上述XML作为请求的主体发送时，我得到以下XML作为响应，并获得200作为响应代码。

    <?xml version='1.0' encoding='UTF-8'?>

</entry>
</feed>

下面是我的Java代码

String getUrl = "https://www.google.com/m8/feeds/contacts/default/full/batch?oauth_token=" + accessToken;
URL url = new URL(getUrl);
HttpURLConnection con = (HttpURLConnection) url.openConnection();
con.setDoOutput(true);
con.setRequestMethod("POST");
con.setRequestProperty("Content-Type", "application/atom+xml");
con.setRequestProperty("Gdata-version","3.0");      
con.setRequestProperty("Content-Length", Integer.toString(responseXML.length()));
//responseXML is body of the request
con.getOutputStream().write(responseXML.getBytes("UTF8"));
System.out.println(con.getResponseCode() + ":" + con.getResponseMessage());

批处理插入操作正常运行。但是更新和删除操作无法正常工作。

我尝试用https://issuetracker.google.com/issues/36756279

中的建议将uri中的base完全替换为

但是我遇到了同样的错误。有什么建议吗？

Answer 1

我修改了请求XML，最后使我的代码正常工作。

我用'default'（我的邮件ID）替换了XML中的每个userEmail。

我仍然不知道为什么代码会产生'default'错误。我知道

The special userEmail value default can be used to refer to the authenticated user

但是单独的添加，删除和更新操作可以与default值完美配合，而批处理操作不能与默认值一起使用。
