我一直在为谷歌阅读器开发一个客户端。一切正常，除了我无法编辑条目以添加“已加星标”和“已读”等标签。code.google.com/p/pyrfeed/wiki/GoogleReaderAPI 和 www.niallkennedy.com/blog/2005/12/google-reader-api.html 上的说明似乎已经过时。更奇怪的是，我一直在检查谷歌自己使用的 POST 数据并试图准确地复制它，但我仍然无法让它工作。例如，我最接近的是 http://www.google.com/reader/api/0/edit-tag和 POST 数据 a=/user/-/state/com.google/starred&async=true&s= [饲料]&i=[项目]&T=[令牌]

这似乎正是谷歌本身所做的，但我总是得到“无效的流名称”。有什么建议吗？

我没有给你一个明确的答案，但我在 API api/0/edit-tag 上也遇到了一些问题，并设法让它们工作。

我已经毫无问题地使用了 API 的其他部分（api/0/stream/items/ids、api/0/unread-count），但是这一部分工作起来并不容易。

过了一会儿，我重新开始检查他们的网络前端（使用 Chrome 开发工具）发送给谷歌阅读器的请求，并做了一个硬编码的例子（你可以使用这个代码，你只需要为你自己更改 id 和流- 请注意它们具有所有需要的前缀：feed/ 用于流，tag:google.com,2005:reader/item/ 用于 id)。

        String authToken = getGoogleAuthKey();
        // I use Jsoup for the requests, but you can use anything you
        // like - for jsoup you usually just need to include a jar
        // into your java project
    Document doc = Jsoup.connect("http://www.google.com/reader/api/0/edit-tag")
        .header("Authorization", _AUTHPARAMS + authToken)
        .data(
                    // you don't need the userid, the '-' will suffice
                "a", "user/-/state/com.google/read",
                "async", "true",
                "s", "feed/http://www.gizmodo.com/index.xml",
                "i", "tag:google.com,2005:reader/item/1a68fb395bcb6947",
                "T", "//wF1kyvFPIe6JiyITNnMWdA"
        )
        // I also send my API key, but I don't think this is mandatory
        .userAgent("[YOUR_APP_ID_GOES_HERE].apps.googleusercontent.com")
        .timeout(10000)
        // don't forget the post! (using get() will not work)
        .**post()**;

这是我将流中的特定项目标记为已读的最终代码（translateToItemAtomId 方法用于将 api/0/stream/items/ids 返回的长整数 id 转换为该 API 接受的 atom xml id）：

        String authToken = getGoogleAuthKey();
    Document doc = Jsoup.connect("http://www.google.com/reader/api/0/edit-tag")
        .header("Authorization", _AUTHPARAMS + authToken)
        .data(
                "a", "user/-/state/com.google/read",
                "async", "true",
                "s", stream,
                "i", translateToItemAtomId(itemId),
                "T", getGoogleToken(authToken)
        )
        .userAgent("[YOUR_APP_ID_GOES_HERE].apps.googleusercontent.com")
        .timeout(10000).post();

您可能需要一些额外的代码（基于http://www.chrisdadswell.co.uk/android-coding-example-authenticating-clientlogin-google-reader-api/）：

    private static final String _AUTHPARAMS = "GoogleLogin auth=";
private static final String _GOOGLE_LOGIN_URL = "https://www.google.com/accounts/ClientLogin";
private static final String _READER_BASE_URL = "http://www.google.com/reader/";
private static final String _API_URL = _READER_BASE_URL + "api/0/";
private static final String _TOKEN_URL = _API_URL + "token";
private static final String _USER_INFO_URL = _API_URL + "user-info";
private static final String _USER_LABEL = "user/-/label/";
private static final String _TAG_LIST_URL = _API_URL + "tag/list";
private static final String _EDIT_TAG_URL = _API_URL + "tag/edit";
private static final String _RENAME_TAG_URL = _API_URL + "rename-tag";
private static final String _DISABLE_TAG_URL = _API_URL + "disable-tag";
private static final String _SUBSCRIPTION_URL = _API_URL
        + "subscription/edit";
private static final String _SUBSCRIPTION_LIST_URL = _API_URL
        + "subscription/list";

public static String getGoogleAuthKey() throws IOException {
    String _USERNAME = "USER_EMAIL@gmail.com";
    String _PASSWORD = "USER_PASSWORD";

    Document doc = Jsoup
            .connect(_GOOGLE_LOGIN_URL)
            .data("accountType", "GOOGLE", "Email", _USERNAME, "Passwd",
                    _PASSWORD, "service", "reader", "source",
                    "[YOUR_APP_ID_GOES_HERE].apps.googleusercontent.com")
            .userAgent("[YOUR_APP_ID_GOES_HERE].apps.googleusercontent.com")
            .timeout(4000).post();

    // RETRIEVES THE RESPONSE TEXT inc SID and AUTH. We only want the AUTH
    // key.
    String _AUTHKEY = doc
            .body()
            .text()
            .substring(doc.body().text().indexOf("Auth="),
                    doc.body().text().length());
    _AUTHKEY = _AUTHKEY.replace("Auth=", "");
    return _AUTHKEY;
}

// generates a token for edition, needed for edit-tag
public static String getGoogleToken(String authToken) throws IOException {
    Document doc = Jsoup.connect(_TOKEN_URL)
            .header("Authorization", _AUTHPARAMS + getGoogleAuthKey())
            .userAgent("[YOUR_APP_ID_GOES_HERE].apps.googleusercontent.com")
            .timeout(10000).get();

    // RETRIEVES THE RESPONSE TOKEN
    String _TOKEN = doc.body().text();
    return _TOKEN;
}

希望这可以帮助！
