PHP cURL,POST JSON

导读：我需要POST以下 JSON代码,但由于某种原因,它不起作用.以下是我有的代码. $fieldString = "395609399";//the curl request processorfunction processCurlJsonrequest($URL,$fieldString) { //Initiate cURL request and send back the result $ch = curl_ini

我需要POST以下 JSON代码,但由于某种原因,它不起作用.以下是我有的代码.

$fieldString = "395609399";
//the curl request processor
function processCurlJsonrequest($URL,$fieldString) { //Initiate cURL request and send back the result
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_HTTPHEADERS,array('Content-Type: application/json'));
    curl_setopt($ch,CURLOPT_URL,$URL);
    curl_setopt($ch,CURLOPT_USERAGENT,$this->_agent);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
    curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,0);
    curl_setopt($ch,CURLOPT_COOKIEFILE,$this->_cookie_file_path);
    curl_setopt($ch,CURLOPT_COOKIEJAR,CURLOPT_FOLLOWLOCATION,TRUE);
    curl_setopt($ch,CURLOPT_VERBOSE,TRUE);
    if ($fieldCount) { // in case of post fields present then pass it on
        curl_setopt($ch,CURLOPT_POSTFIELDS,json_encode("{categoryId: $fieldString}"));
        curl_setopt($ch,CURLOPT_POST,1);
    }
    $resulta = curl_exec($ch);
    if (curl_errno($ch)) {
        print curl_error($ch);
    } else {
        curl_close($ch);
    }
    return $resulta;
}

这是调用cURL请求的函数：

function get_cat($categoryId,$URL) {
    $fields = array(
        "categoryId" => $categoryId
    );
    $fields_string = $fields;
    return $this->processCurlJsonrequest($URL,$fields_string);
}

问题的一点是：

curl_setopt($ch,json_encode("{categoryId: $fieldString}"));

CURLOPT_POSTFIELDS将接受参数数组或URL编码的参数串：

curl_setopt($ch,array('json'=>json_encode($stuff)));
curl_setopt($ch,'json='.urlencode(json_encode($stuff)));

其中json将是POST字段的名称(即：将导致$_POST [‘json’]可访问).
