Question

我有以下代码来获取fb页面列表

int readLine(FILE *infile, char **line_buffer) {
    char * line = NULL;
    size_t len = 0;
    ssize_t read;

    while ((read = getline(&line, &len, infile)) != -1) {
        *line_buffer = line;
        if(read == 0 || read == -1)
            return -1;

        return 1;
    }
}

struct node *readStringList(FILE *infile) {
    char* str_buffer;
    while(readLine(infile, &str_buffer) == 1) {
        // do something with str_buffer
        // though remember to save it somewhere, you need to free() it later
    }
    [...]

$ pagedata 和 $ pages 为空，因此不会填充下拉列表。

在页面顶部的某处，我使用的是db.tests.aggregate({ $redact: { $cond: { if: {$eq: [ {$setIsSubset: [ '$a', [ "1", "2", "3" ] ]}]}, then: '$$KEEP', else: '$$PRUNE' } } })，最后是$graph_url_pages = "https://graph.facebook.com/me/accounts?access_token=".$_SESSION['token']; $pagedata=file_get_contents($graph_url_pages); echo "DATA : <br>"; print_r($pagedata); $pages=json_decode($pagedata,true); var_dump($pages); $dropdown = ""; for($i=0;$i<count($pages->data);$i++) { if($me=="iamindex"){ $dropdown .= "<option value='".$pages->data[$i]->access_token."-".$pages->data[$i]->id."'>".$pages->data[$i]->name."</option>"; }elseif($me=="iammulti"){ $dropdown .= "<input type='checkbox' name='page' id='status' value='".$pages->data[$i]->access_token."-".$pages->data[$i]->id."'>".$pages->data[$i]->name."<br>"; }else{$dropdown.="<option value=''>No Category Selection</option>";} }并且需要它们。我不知道这是不是问题。

如果有人可以指出出了什么问题，那会很棒！如果需要更多代码，我可以提供。请注意我是业余程序员。自学成才。

我建议使用cURL

  $graph_url_pages = "https://graph.facebook.com/me/accounts?access_token=".$_SESSION['token'];

  $ch = curl_init();
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_URL, $graph_url_pages);

  if(curl_error($c))
  {
     echo 'error:' . curl_error($c);
     //it will produce the error if any exists 
  } 

  $data = curl_exec($ch);
  curl_close($ch);
  print_r($data);

获取fb页面数据时，php文件获取内容不起作用
