我正在尝试使用带有请求的协议规范来为 Google 电子表格实现一些基本功能。

我这样做的原因是因为它适用于 Android，而 gdata-java 库并不能真正工作，而 alpha android 库并没有真正削减它。我设法实现了身份验证，并获取列表和删除，但是对于编辑\更新一行，我真的无法完全理解它。

例如我想改变一个单元格的内容 这里是协议的规范

根据我的理解，我必须向编辑 URL 发送某种 atom 或 xml 格式的请求。我从来没有发送过这种类型的请求。

我还发现 了这个，它提供了一个关于应该如何完成的线索（也是论坛上一个未回答的问题），但并没有真正管理它。

这是我的身份验证功能，如果您需要它，因此如果您想尝试编写它，请不要再次实现它。

/**
 * Logs in to the Google service using the ClientLogin HttpRequest API and returns an authentification token
 */
 private String getAuthToken() {


HttpClient httpclient = new DefaultHttpClient();

HttpPost httppost = new HttpPost(CLIENT_LOGIN_ADDRESS);

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("accountType", "GOOGLE"));
nameValuePairs.add(new BasicNameValuePair("Email", "username@gmail.com"));
nameValuePairs.add(new BasicNameValuePair("Passwd", "password"));
nameValuePairs.add(new BasicNameValuePair("service", "wise"));
nameValuePairs.add(new BasicNameValuePair("source", SERVICE_NAME));

try {
  httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
}
catch (UnsupportedEncodingException e) {
  //Log.e("ERROR", "UnsupportedEncodingException");
}

//Log.v("TEST", "Executing request " + httppost.getURI());

ResponseHandler<String> responseHandler = new BasicResponseHandler();
String responseBody = null;

try {
  responseBody = httpclient.execute(httppost, responseHandler);
}
catch (ClientProtocolException e) {
  //Log.e("ERROR", "ClientProtocolException");
}
catch (IOException e) {
  //Log.e("ERROR", "IOException");
}

//Log.v("TEST", "response:" + responseBody);

String[] vals = responseBody.split("\n")[2].split("=");
String auth_string = vals[1];
//Log.v("TEST", "auth_token:" + vals[1]);

return auth_string;
}

这是我正在尝试的更新功能，请注意，如果您尝试它，我的文档的编辑 URL 将不起作用，这只是我目前所拥有的一个 iea：

/**
 * Ignore this i use it for testing
 */
 public void justTesting() {

String url = "http://spreadsheets.google.com/feeds/cells/tl7RKkCaAxvO1f3U9Y8k5Dw/od6/private/full/R2C1/1q0cdh";

HttpClient httpclient = new DefaultHttpClient();

HttpPut httpput = new HttpPut(url);
httpput.addHeader(new BasicHeader("Authorization", "GoogleLogin auth=" + getAuthToken()));
httpput.addHeader(new BasicHeader("GData-Version", "2.0"));

HttpEntity he = null;

String messageBody = "<entry>"+
                     "<id>https://spreadsheets.google.com/feeds/cells/tl7RKkCaAxvO1f3U9Y8k5Dw/od6/private/full/R2C1</id>"+
                     "<link rel=\"edit\" type=\"application/atom+xml\""+
                     "  href=\"https://spreadsheets.google.com/feeds/cells/tl7RKkCaAxvO1f3U9Y8k5Dw/od6/private/full/R2C1\"/>"+
                     "<gs:cell row=\"2\" col=\"2\" inputValue=\"300\"/>"+
                      "</entry>";


try {
  he = new StringEntity(messageBody);
}
catch (UnsupportedEncodingException e) {
  //Log.e("ERROR", "UnsupportedEncodingException");
}

httpput.setEntity(he);


try {

  HttpResponse hr = httpclient.execute(httpput);
  //Log.d("DEBUG", "sl : " + hr.getStatusLine());
}
catch (ClientProtocolException e) {
  //Log.e("ERROR", "ClientProtocolException");
}
catch (IOException e) {
  //Log.e("ERROR", "IOException");
}

//Log.v("TEST", "executed");

}

这当前给出了 400 Bad 请求。我也在尝试使用 Apache HttpClient 来实现这一点。

有没有人知道如何实现\实施\我应该如何发送什么请求？

谢谢，您的帮助将不胜感激。

我取得了一些进展并写了这个：

public void justTesting() {

String url = "https://spreadsheets.google.com/feeds/cells/tl7RKkCaAxvO1f3U9Y8k5Dw/od6/private/full/R2C1";

HttpClient httpclient = new DefaultHttpClient();

HttpPut httpput = new HttpPut(url);
httpput.addHeader(new BasicHeader("Authorization", "GoogleLogin auth=" + getAuthToken()));
httpput.addHeader(new BasicHeader("GData-Version", "3.0"));

HttpEntity he = null;

String messageBody = "<entry xmlns='http://www.w3.org/2005/Atom' xmlns:gs='http://schemas.google.com/spreadsheets/2006'> <id>http://spreadsheets.google.com/feeds/cells/tl7RKkCaAxvO1f3U9Y8k5Dw/od6/private/full/R2C1 </id> <gs:cell row='2' col='1' inputValue='mouuuuuuuuusee'/> </entry>";
  //RequestEntity requestEntity = new StringRequestEntity(xml.toString(), "application/atom+xml", "UTF-8");


try {
  he = new StringEntity(messageBody);
}
catch (UnsupportedEncodingException e) {
  Log.e("ERROR", "UnsupportedEncodingException");
}

httpput.addHeader("Content-Type", "application/atom+xml");
httpput.setEntity(he);


try {
  HttpResponse hr = httpclient.execute(httpput);
  Log.d("DEBUG", "sl : " + hr.getStatusLine());
}
catch (ClientProtocolException e) {
  Log.e("ERROR", "ClientProtocolException");
}
catch (IOException e) {
  Log.e("ERROR", "IOException");
}

Log.v("TEST", "executed");

}

现在它给了我一个 403 Forbidden。知道为什么吗？

嘿，我想通了，我错过了这个：

httpput.addHeader(new BasicHeader("If-Match", "*"));

现在函数看起来像这样：

  public void justTesting() {

String url = "http://spreadsheets.google.com/feeds/cells/t9VU1IwRrmG3h-nhI_J2fzg/od6/private/full/R2C1";

HttpClient httpclient = new DefaultHttpClient();

HttpPut httpput = new HttpPut(url);
httpput.addHeader(new BasicHeader("Authorization", "GoogleLogin auth=" + getAuthToken()));
httpput.addHeader(new BasicHeader("GData-Version", "2.0"));
httpput.addHeader(new BasicHeader("If-Match", "*"));

HttpEntity he = null;

String messageBody = "<entry xmlns='http://www.w3.org/2005/Atom' xmlns:gs='http://schemas.google.com/spreadsheets/2006'> <id>http://spreadsheets.google.com/feeds/cells/tl7RKkCaAxvO1f3U9Y8k5Dw/od6/private/full/R2C1</id> <link rel='edit' type='application/atom+xml' href='http://spreadsheets.google.com/feeds/cells/t9VU1IwRrmG3h-nhI_J2fzg/od6/private/full/R2C1/1en5'/> <gs:cell row='2' col='1' inputValue='mouuuuuuuuusee' /> </entry>";

try {
  he = new StringEntity(messageBody);
}
catch (UnsupportedEncodingException e) {
  Log.e("ERROR", "UnsupportedEncodingException");
}

httpput.addHeader("Content-Type", "application/atom+xml");
httpput.setEntity(he);


try {
  HttpResponse hr = httpclient.execute(httpput);
  Log.d("DEBUG", "sl : " + hr.getStatusLine());
}
catch (ClientProtocolException e) {
  Log.e("ERROR", "ClientProtocolException");
}
catch (IOException e) {
  Log.e("ERROR", "IOException");
}

Log.v("TEST", "executed");

}
