Question

我一直在为谷歌阅读器的客户工作。一切正常，但我无法编辑条目以添加标签，如“已加星标”和“已阅读”。 code.google.com/p/pyrfeed/wiki/GoogleReaderAPI和www.niallkennedy.com/blog/2005/12/google-reader-api.html上的说明似乎已过时。更奇怪的是，我一直在检查谷歌本身使用的POST数据，并试图完全复制它，但我仍然无法让它工作。我最接近的是，例如，http://www.google.com/reader/api/0/edit-tag有POST数据a = / user / - / state / com.google / starred＆amp; async = true＆amp; s = [feed]＆amp; i = [item] ＆amp; T公司= [令牌]

这似乎正是谷歌本身所做的，但我总是回到“无效的流名称”。有什么建议吗？

我没有给你一个明确的答案，但我在使用API api / 0 / edit-tag时遇到了一些麻烦，并设法让它们正常工作。

我已经在使用API的其他部分而没有任何问题（api / 0 / stream / items / ids，api / 0 / unread-count），但是这个部分并没有那么容易。

过了一段时间，我开始检查通过他们的网络前端发送到谷歌阅读器的请求（使用Chrome开发工具），并做了一个硬编码的例子（你可以使用这个代码，你只需要更改ID和流对于你自己 - 只要小心他们拥有所有需要的前缀：feed / for stream，以及tag：google.com，2005：reader / item / for 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标记为read的最终代码（translateToItemAtomId方法用于将api / 0 / stream / items / ids返回的长整数id转换为此接受的atom xml id API）：

        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();

您可能需要的一些额外代码（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;
}

希望这有帮助！
