问题描述

我试图访​​问与C流API,和我用下面的code:

I'm trying to access the Streaming API with C, and am using the following code:

#include <stdio.h>
#include <curl/curl.h>

int main(void)
{
  CURL *curl;
  CURLcode res;

  curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "http://stream.twitter.com/1/statuses/sample.json?delimited=length -uJEggers2:password");
    res = curl_easy_perform(curl);
    printf("results: %c", res);
    /* always cleanup */ 
    curl_easy_cleanup(curl);
  }
  return 0;
}

这没什么打印在执行时,我究竟做错了什么?谢谢。
修改的code工作时,我用google.com的网址,但它只是似乎是与流API的问题。有任何想法吗?

This prints nothing upon execution, what am I doing wrong? Thanks. The Code works when I use google.com as the URL, but it just seems to be an issue with the Streaming API. Any Ideas?

推荐答案

函数 curl_easy_perform( )只返回错误code。要实际检索数据,你必须设置 CURLOPT_WRITEFUNCTION 以自己回调函数。

The function curl_easy_perform() only returns the error code. To actually retrieve the data you'll have to set CURLOPT_WRITEFUNCTION to your own callback function.

编辑:您也不能使用-uJEggers2:密码中的URL字符串,你必须设置使用的 CURLOPT_HTTPAUTH CURLOPT_USERNAME CURLOPT_PASSWORD

You also can't use " -uJEggers2:password" in the URL string, you'll have to set the authentication options using CURLOPT_HTTPAUTH, CURLOPT_USERNAME and CURLOPT_PASSWORD.
