A Twitter API Wrapper Library for C.
- REST APIs(GET/POST) Support
- Streaming APIs Support
- libcurl
- openssl
You should include for using t4c these headers:
- t4c/parameters.h
- t4c/string.h
- t4c/t4c.h
- sds/sds.h
#include <t4c/parameters.h>
#include <t4c/string.h>
#include <t4c/t4c.h>
#include <sds/sds.h>#At first, Define and Initialize an instance of T4C
T4C t4c = {
.consumerKey = sdsnew("Your Consumer Key"),
.consumerSecret = sdsnew("Your Consumer Secret"),
.accessToken = sdsnew("Your AccessToken"),
.accessTokenSecret = sdsnew("Your AccessTokenSecret")
};This Library provides only manual way to access Twitter API Like Twitter4D.
This means that t4c doesn't provides functions for each of the APIs, only request function.
#Parameters Preparing parameters for each of the API gose like: ##1. Define and Initialize parameters
Parameters* params = new_parameters();##2. Add parameter's key and that of value
add_parameter(params, sdsnew("Key"), sdsnew("Value"));##If the parameters are unneeded, you should free as follows
free_parameters(params);#REST APIs(POST/GET)
Using request function.
Function prototype declaration is:
string request(T4C* t4c, METHOD method, string endPoint, Parameters* paramsArgument);
/*
Parameters:
t4c: pointer for an instance of T4C
method: specification whether the request is POST or GET
endPoint: specification of endPoint(Ex: /foo/bar.json)
paramsArgument: parameters for the endPoint
Returns:
string of raw Twitter returned JSON
If you need returned value, you must use some JSON parser(This library doesn't serve it)
*/##POST request. for example: statuses/update.json
Parameters* params = new_parameters();
add_parameter(params, sdsnew("status"), sdsnew("Hello World!"));
string result = request(&t4c, POST, sdsnew("/statuses/update.json"), params);
printf("RESULT for Tweet: %s\n", string_get_value(result));
free_parameters(params);##GET request. for example: account/verify_credentials.json This API doesn't require essential parameter.
string result = request(&t4c, GET, sdsnew("/account/verify_credentials.json"), NULL);
printf("RESULT for /account/verify_credentials.json: %s\n", string_get_value(result));#Streaming API You can use Streaming API, but must should prepare callback function for each result of Streaming API as libcurl callback, like:
static size_t streaming_callback_sample(void* ptr, size_t size, size_t nmemb, void* data) {
if (size * nmemb == 0)
return 0;
size_t realsize = size * nmemb;
string* str = (string*)data;
str->length = realsize + 1;
str->value = MALLOC_TN(char, str->length);
if (str->value != NULL) {
memcpy(str->value, ptr, realsize);
strcat(str->value, "\0");
fprintf(stderr, "RECIEVED: %ld bytes\n", realsize);
fprintf(stderr, "[STREAMING API] received -> %s\n", str->value);
}
return realsize;
}##UserStream user.json
stream(&t4c, sdsnew("https://userstream.twitter.com/1.1/user.json"), NULL, streaming_callback_sample);
/*
If any result from twitter recives, streaming_callback_sample is called.
*/##Filtered Stream statuses/filter.json
Parameters* params = new_parameters();
add_parameter(params, sdsnew("track"), sdsnew("foobar"));
stream(&t4c, sdsnew("https://stream.twitter.com/1.1/statuses/filter.json"), params, streaming_callback_sample);
free_parameters(params);$ make static: build a static library(t4c.a)
$ make shared: build a shared library(t4c.so)
$ make test: build a test binary(t4c_test/t4c_test) this job is equivalent to $ make test_static in directly t4c_test/
