postdata

Post Twitter data

Syntax

d = postdata(c,baseurl)
d = postdata(c,baseurl,parameters)
d = postdata(c,baseurl,QueryName1,QueryValue1,...,QueryNameN,QueryValueN)

Description

example

d = postdata(c,baseurl) posts Twitter® data for REST API POST endpoints that do not require any web service query parameters.

example

d = postdata(c,baseurl,parameters) posts Twitter data using web service query parameters. The Twitter REST API defines web service query parameters for each endpoint. For valid parameters, see the Twitter REST API Endpoint Reference Documentation.

example

d = postdata(c,baseurl,QueryName1,QueryValue1,...,QueryNameN,QueryValueN) specifies web service query parameters as one or more pairs of name-value arguments.

Examples

collapse all

Use a Twitter connection object to check Twitter account settings. The REST API endpoint POST account/settings does not require any web service query parameters.

Create a Twitter connection using your credentials. (The values in this example do not represent real Twitter credentials.)

consumerkey = 'abcdefghijklmnop123456789';
consumersecret = 'qrstuvwxyz123456789';
accesstoken = '123456789abcdefghijklmnop';
accesstokensecret = '123456789qrstuvwxyz';

c = twitter(consumerkey,consumersecret,accesstoken,accesstokensecret);

Check the Twitter connection. If the StatusCode property has the value OK, the connection is successful.

c.StatusCode
ans = 

    OK

Specify the Twitter base URL.

baseurl = 'https://api.twitter.com/1.1/account/settings.json';

Retrieve account settings using the Twitter connection object and base URL.

d = postdata(c,baseurl)
d = 

  ResponseMessage with properties:

    StatusLine: 'HTTP/1.1 200 OK'
    StatusCode: OK
        Header: [1×22 matlab.net.http.HeaderField]
          Body: [1×1 matlab.net.http.MessageBody]
     Completed: 0

d is a matlab.net.http.ResponseMessage object. The StatusCode property shows OK, indicating a successful HTTP request.

Access account settings data. Display the structure Data.

d.Body.Data
ans = 

  struct with fields:

                       protected: 0
                     screen_name: 'screenName'
                always_use_https: 1
      use_cookie_personalization: 0

    discoverable_by_mobile_phone: 0
         display_sensitive_media: 0
       allow_contributor_request: 'none'
                  allow_dms_from: 'following'
            allow_dm_groups_from: 'following'
                 translator_type: 'none'

(These values do not represent real Twitter data.)

You can post data using other REST API endpoints by substituting another URL for the baseurl input argument.

Use a Twitter connection object to create a Twitter search. Specify the search term for the saved search using a structure.

Create a Twitter connection using your credentials. (The values in this example do not represent real Twitter credentials.)

consumerkey = 'abcdefghijklmnop123456789';
consumersecret = 'qrstuvwxyz123456789';
accesstoken = '123456789abcdefghijklmnop';
accesstokensecret = '123456789qrstuvwxyz';

c = twitter(consumerkey,consumersecret,accesstoken,accesstokensecret);

Check the Twitter connection. If the StatusCode property has the value OK, the connection is successful.

c.StatusCode
ans = 

    OK

Specify the search term MathWorks as a field of the structure parameters. Specify the Twitter base URL for the REST API POST endpoint POST saved_searches/create.

parameters.query = 'MathWorks';
baseurl = 'https://api.twitter.com/1.1/saved_searches/create.json';

Create a saved search using the Twitter connection object, base URL, and structure parameters.

d = postdata(c,baseurl,parameters)
d = 

  ResponseMessage with properties:

    StatusLine: 'HTTP/1.1 200 OK'
    StatusCode: OK
        Header: [1×23 matlab.net.http.HeaderField]
          Body: [1×1 matlab.net.http.MessageBody]
     Completed: 0

d is a matlab.net.http.ResponseMessage object. The StatusCode property shows OK, indicating a successful HTTP request.

Access the saved search data.

d.Body.Data
ans = 

  struct with fields:

            id: 8.6011e+17
        id_str: '860112019273416704'
         query: 'MathWorks'
          name: 'MathWorks'
      position: []
    created_at: 'Thu May 04 12:41:00 +0000 2017'

d.Body.Data is a structure that contains information about the saved search in fields. For example, the field query contains the search term MathWorks as a character vector.

You can post data using other REST API endpoints by substituting another URL for the baseurl input argument.

Use a Twitter connection object to create a Twitter search. Specify the search term for the saved search as a name-value argument.

Input Arguments

collapse all

Twitter connection, specified as a twitter object.

Twitter base URL, specified as a character vector or string scalar. Use this URL to access the Twitter REST API endpoints.

Example: 'https://api.twitter.com/1.1/followers/list.json' specifies a GET REST API endpoint.

Data Types: char | string

Web service query parameters, specified as a structure. Each parameter is specified as a field in the structure. Set the field to a specific value in the structure. For example, specify the number of items for the HTTP request:

parameters.count = 20;

The Twitter REST API defines web service query parameters that it accepts as part of an HTTP request. For valid parameters, see the Twitter REST API Endpoint Reference Documentation.

Data Types: struct

Web service query parameters, specified as one or more pairs of name-value arguments. A QueryName argument is a character vector or string scalar that specifies the name of a query parameter. A QueryValue argument is a character vector or string scalar that specifies the value of the query parameter.

The Twitter REST API defines web service query parameters that it accepts as part of an HTTP request. For valid parameters, see the Twitter REST API Endpoint Reference Documentation.

Example: 'count',20 specifies the number of items for the HTTP request.

Data Types: char | string

Output Arguments

collapse all

Twitter data, returned as a matlab.net.http.ResponseMessage object.

To retrieve Twitter data, access properties in d, for example:

data = d.Body.Data
data = 
    
      struct with fields:
    
               statuses: {50×1 cell}
        search_metadata: [1×1 struct]

Continue to access the nested structure data to retrieve Twitter data. For accessing nested structures, see Access Data in Nested Structures (MATLAB).
