[英]PHP cURL, POST JSON
我需要POST以下JSON代碼,但由於某種原因它無法正常工作。 以下是我的代碼。
$fieldString = "395609399";
//the curl request processor
function processCurlJsonrequest($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, $this->_cookie_file_path);
curl_setopt($ch, 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 $resulta;
}
這是調用cURL請求的函數:
function get_cat($categoryId, $URL) {
$fields = array(
"categoryId" => $categoryId
);
$fields_string = $fields;
return $this->processCurlJsonrequest($URL, $fields_string);
}
問題是:
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode("{categoryId: $fieldString}"));
CURLOPT_POSTFIELDS將接受參數數組或URL編碼的參數字符串:
curl_setopt($ch, CURLOPT_POSTFIELDS, array('json'=>json_encode($stuff)));
curl_setopt($ch, CURLOPT_POSTFIELDS, 'json='.urlencode(json_encode($stuff)));
其中json
將是POST字段的名稱(即:將導致$_POST['json']
可訪問)。
發送沒有JSON編碼的文本,並添加此標題代碼:
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json; charset=utf-8","Accept:application/json, text/javascript, */*; q=0.01"));
在最初的示例中,工作代碼應如下所示:
//the curl request processor
function processCurlJsonrequest($URL, $fieldString) { //Initiate cURL request and send back the result
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, 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, $this->_cookie_file_path);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_VERBOSE, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode(array("myJsonData" => "test")));
curl_setopt($ch, CURLOPT_POST, 1);
$resulta = curl_exec($ch);
if (curl_errno($ch)) {
print curl_error($ch);
} else {
curl_close($ch);
}
return $resulta;
}
我有問題通過cURL發送JSON,問題是我沒有在標頭中明確設置內容長度。
所以標題應該是:
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Content-Length: ' . strlen($json)));
這很簡單,確保你為json設置了額外的Content-Type標頭集,然后CURLOPT_POSTFIELDS可以將json作為字符串。 無需編碼。
