400 Bad request with "mark as" (using android)

[Quint]

Hello,

I'm trying to use the Google Reader API for my android app and i'm
having trouble marking items as read. I'm getting 400 bad request.

Other things do work: Logging in, Getting a token, getting
subscriptions.items etc.

I'm using apache HttpClient 4. I have almost the same thing working as
a standard java application only that one uses HttpClient 3 so i had
to change it i little bit for android. But since that is working i
know a have all the parameters and headers correct.

One thing that is different from the working java version is the way
the parameters are passed in the request. In the android version it's
like this:
public String post(String pUrl, List<Parameter> pParams, boolean
pUseCookies) throws GoogleReaderException {

ArrayList<NameValuePair> postParameters =
(ArrayList<NameValuePair>) (toNameValuePairArray(pParams));

HttpPost postRequest = new HttpPost(pUrl);

try {
postRequest.setEntity(new UrlEncodedFormEntity(postParameters,
HTTP.UTF_8));
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}

return execute(postRequest, pUseCookies);
}



Here are some details of the request and response from the android
eclipse debugger:

uri :

https://www.google.com/reader/api/0/edit-tag

postparameters(before passed to UrlEncodedFormEntity()):

[s=feed%2Fhttp%3A%2F%2Fwww.androidworld.nl%2Ffeed%2F, i=tag
%3Agoogle.com%2C2005%3Areader%2Fitem%2F6ef6e1f6dc7771f9, T=//
vwbWgfeJ5Sc03YiQ-1D3Pw, async=true, pos=0, a=user/**********/state/
com.google/read]

headers:

[Authorization: GoogleLogin
auth=DQAAAMUAAAAIpsBx9lbuZgs9yVNX4LOiKyRCj7l6KOvuq_M8-AEoFf-
U2uqGuzSqsOU943W3bgYMalT1yZi0sQoKIwllp-

This kind of post works for login but somehow doesn't work now.

What is wrong?

Let me know if i need to post more detailed info (and what)

Thanks!

One possible 400 bad request error:

Check if your used token is still valid. Google Reader sets the
response header "X-Reader-Google-Bad-Token" to "true" when it is
invalid.

Hi,

The response header does not contain "X-Reader-Google-Bad-Token" so i
don't thing thats it..

Sorry, but you really checked the response headers and not your
request headers as shown in your first post?

Do you see the other google reader specific response headers like:
X-Reader-Google-Version
X-Reader-User
...

This is a example when i post it:
async=true&i=tag%3Agoogle.com%2C2005%3Areader%2Fitem
%2F12169a891a3530a6&s=feed%2Fhttp%3A%2F%2Ffeeds.ismashphone.com
%2Ftypepad%2F1209935315s4903%2Fismasher&a=user%2F-%2Fstate%2Fcom.google
%2Fread&T=....

This is the "header collection" in the response object:

[Content-Type: text/html; charset=UTF-8, X-Reader-Google-Version:
546-000, X-Reader-User: 11196327406850766973, Set-Cookie: GRLD=en:

Hello everybody,

I knows this is an old message but i'm still having this same issue.

I keep getting 400 back when a try to mark items.

I'm using Apache HttpClient on Android now but i also tried HttpUrlConnection both fail.

I have made a TCP dump on a running Android emulator and used Wireshark to analyze the packet.

I used HTTP in stead of HTTPS to be able so view the details.

I don't see what's wrong with my request.

Below are the details for the request and result.

Does anybody see what thew problem could be?

(If necessary i could post mote details from Wireshark but i thought the rest was too "low-level".)

One thing i do notice is that the edit token (T parameter) eventually get's urlencoded. But this is just how HttpClient does this i suppose:

T=%2F%2Ftan-6fN_6O_DC_KKj1Ew8Q

Could this be a problem?

These are the details:

Request:

I really hope someone can shed some light on this!

Hello,

 

When using Java HttpUrlConnection i received a response with "X-Reader-Google-Bad-Token true" in the header in combination with 400 Bad Request (and not 401).

Does "X-Reader-Google-Bad-Token" always mean that the token is expired? or can it also mean that the token is invalid some other way?

Because i request a new action token each request so i don't see how it can be expired.

This is what i do:

1. Use Android AccountManager to request a Auth token (each time a new one). This token works for authenticated GET requests.
2. Use the token to send a authenticated request for a action token. I successfully receive a action token.
3. Use the action token for any edit post request to Google Reader but always fails with 400

All my post requests that edit something result in a 400 bad Request but all my GET requests are successful.

I also tried to not encode the action token param.

So what are the possible reasons for "X-Reader-Google-Bad-Token true" (+ 400 Bad Request)?

 

thanks.
