我的PHP服务器上出现未知JSON错误

我正在开发一个允许数据从Android传输到PHP服务器的应用程序，我不知道为什么它不支持JSON

这是我的密码：

<?php
JSON.parse();
$decode = json_decode($_REQUEST['request']);
$json = $decode->name;
header('Content-type:application/json');
echo json_encode($json);
?>

检查您的JSON地址 如果JSON有效，则php代码可能不正确

显示一些具体代码。

您可以使用以下代码从android以字符串形式发送Json数据：

BufferedReader reader = null;

        // Send data
        try {

            /* forming th java.net.URL object */
            URL url = new URL(this.url);
            urlConnection = (HttpURLConnection) url.openConnection();
            urlConnection.setRequestProperty("Content-Type", "application/json");
            urlConnection.setRequestProperty("Accept", "application/json");
            urlConnection.setRequestMethod("POST");
            urlConnection.connect();

            /* pass post data */
            byte[] outputBytes = jsonData.toString().getBytes("UTF-8");
            OutputStream os = urlConnection.getOutputStream();
            os.write(outputBytes);
            os.close();

            /* Get Response and execute WebService request*/
            int statusCode = urlConnection.getResponseCode();

            /* 200 represents HTTP OK */
            if (statusCode == HttpsURLConnection.HTTP_OK) {

                inputStream = new BufferedInputStream(urlConnection.getInputStream());
                ResponseData= convertStreamToString(inputStream);

            } else {

                ResponseData = null;
            }

    $post_body = file_get_contents('php://input');
    $post_body = iconv('UTF-8', 'UTF-8//IGNORE', utf8_encode($post_body));
    $reqData[] = json_decode($post_body);

    $postData = $reqData[0];
    echo $postData->name;

在php中，您可以通过添加以下代码来获取数据：

BufferedReader reader = null;

        // Send data
        try {

            /* forming th java.net.URL object */
            URL url = new URL(this.url);
            urlConnection = (HttpURLConnection) url.openConnection();
            urlConnection.setRequestProperty("Content-Type", "application/json");
            urlConnection.setRequestProperty("Accept", "application/json");
            urlConnection.setRequestMethod("POST");
            urlConnection.connect();

            /* pass post data */
            byte[] outputBytes = jsonData.toString().getBytes("UTF-8");
            OutputStream os = urlConnection.getOutputStream();
            os.write(outputBytes);
            os.close();

            /* Get Response and execute WebService request*/
            int statusCode = urlConnection.getResponseCode();

            /* 200 represents HTTP OK */
            if (statusCode == HttpsURLConnection.HTTP_OK) {

                inputStream = new BufferedInputStream(urlConnection.getInputStream());
                ResponseData= convertStreamToString(inputStream);

            } else {

                ResponseData = null;
            }

    $post_body = file_get_contents('php://input');
    $post_body = iconv('UTF-8', 'UTF-8//IGNORE', utf8_encode($post_body));
    $reqData[] = json_decode($post_body);

    $postData = $reqData[0];
    echo $postData->name;
