I am getting the same unauthorized like most people. After reading this, it is probably with my signature. I am trying to do a query using the geocode. here is my code:


    var geocode = "42.791306,-86.033448,1mi";
            var baseFormat = "geocode={7}&oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}" +
                            "&oauth_timestamp={3}&oauth_token={4}&oauth_version={5}&q={6}";
        var baseString = string.Format(baseFormat,
                                    oauth_consumer_key,
                                    oauth_nonce,
                                    oauth_signature_method,
                                    oauth_timestamp,
                                    oauth_token,
                                    oauth_version,
                                    Uri.EscapeDataString(q),
                                    Uri.EscapeDataString(geocode)
                                    );

.....

var postBody = "q=" + Uri.EscapeDataString(q) + "&geocode=" + Uri.EscapeDataString(geocode);
            resource_url += "?" + postBody;

Thank you @JoshuaGrippo, your code works. it saved my day. Thakn you

mclen_qlikview · 2013-12-14T16:23:16.000Z

I used to get the same 401 error when I added count and language paramenters, but with solutions from this thread, I am not getting any error after I changed the order of parameters in the baseformat string initialisation. But I don’t see any difference in the output in the list, after I changed the language to “en” and count to 100. Could someone help me in this. Any help would be very much appreciated.

DharaMaheshwari · 2013-12-16T12:27:35.000Z

Hey thanks a lot Britney, it saved my day.
Using your code i can get only 20 tweets what if I want more no. of tweets.
Even I tried to mention
var baseFormat = “count=30&oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}” …
and resource_url += “?” + postBody +"&count=30";
then too only 20 reviews are coming, any help ll be greatly appreciated…
Please reply ASAP as I need it for my college project

AParavantavida · 2014-01-07T11:53:10.000Z

hi Britney,

i am getting user search result as per the given code . But i still get 20 count. its not more than that even if i add 100. please let me know the issue?

String baseFormat = “count=100&oauth_consumer_key={0}&oauth_nonce={1}&oauth_signature_method={2}” +

    string oauth_signature;
    using (HMACSHA1 hasher = new HMACSHA1(ASCIIEncoding.ASCII.GetBytes(compositeKey)))
    {
      oauth_signature = Convert.ToBase64String( hasher.ComputeHash(ASCIIEncoding.ASCII.GetBytes(baseString)));

    }

    var response = (HttpWebResponse)request.GetResponse();

Please help me as soon as possible… thank you!

tsearchhero · 2014-03-02T16:45:00.000Z

Hi Joshua,

code works perfect. But, how can I add geocode and unti parameters to your MakeTwitterCall function. These parameters are listed in this url: https://dev.twitter.com/docs/api/1.1/get/search/tweets

Many of these are working but when I add these two parameters in my IEnumerable<KeyValuePair<string, string>> RequestParameters then twitter send empty results.

Can you help me?
Thanks.

That all looks fine to me I haven’t tried using Geocode at all I can try and get code working for you tomorrow. I can’t promise anything though.

This worked for me you may have your tokens wrong.

hi Britney,
thanks for your code example, It has helped me a lot with my application but i still have a problem.
Im trying to use streaming API and send a POST in order to connect and read tweets to the public stream
https://stream.twitter.com/1.1/statuses/filter.json
I followed your example but i still receive Error 401 Unauthorized.

here my code:


        string URL = "https://stream.twitter.com/1.1/statuses/filter.json";
        string query = "track=twitter";

can you help me to find out what am I doing wrong?

thanks in advance

Hi Britney,

I want to get the replies for this post using twitter api. how can i do it.

twitter.com

Mujeeb Farooqi (MujeebFarooqi)

3G and 4G? Will you use it?

7:38 PM - 24 Apr 2014

i tried many ways but not getting the replies in web response.

Help me out in this.

thanks,
Mujeeb.

MujeebFarooqi · 2014-04-25T10:23:00.000Z

I’m using this example to get the replies on a tweet but return json doesn’t include the replies at all.
https://dev.twitter.com/docs/api/1.1/get/statuses/home_timeline

Please help me on this. I’m using this url:
https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=mujeebfarooqi&count=1&exclude_replies=false

Also, if I want to get the replies of a particular tweet then how i’ll do it?
like sample url: https://twitter.com/MujeebFarooqi/status/459340704356261888

Thanks,
Mujeeb.
