【问题描述】:

我正在尝试从 android 活动将数据连接到我的 sqldatabase 进行注册页面,我收到此错误“org.json.JSONException: Value

首先,谁能建议我在将mysql数据库与php脚本用于android应用程序时如何调试我的程序?因为我通常使用日志猫,但这里的错误不是很清楚:S ...

这是活动代码:

public class Subscribe extends Activity {

    Button bSubscribe;
    EditText etPwdSub, etPwdConf, etLoginSub, etNameSub, etFnSub;
    String result = null;
    InputStream is = null;
    String donnees = "";

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.subscribe);

        etLoginSub = (EditText) findViewById(R.id.etLoginSub);
        etPwdSub = (EditText) findViewById(R.id.etPwdSub);
        etPwdConf = (EditText) findViewById(R.id.etPwdConf);
        etNameSub = (EditText) findViewById(R.id.etNameSub);
        etFnSub = (EditText) findViewById(R.id.etFnSub);

        bSubscribe = (Button) findViewById(R.id.bSubscribe);        
        bSubscribe.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {

                Pattern p = Pattern.compile(".+@.+\\.[a-z]+");
                Matcher m = p.matcher(etLoginSub.getEditableText());

                if (m.matches() == false) {

                    Toast.makeText(
                            getBaseContext(),

                            Toast.LENGTH_SHORT).show();
                } else {

                    // autre méthode : etPwdSub.equals("")

    【解决方案1】:

    您对http://192.168.1.101/spotnshare/subscribe.php 的请求失败并返回非 JSON 字符串(可能是 PHP 错误)。您可以使用

    打印出该值

    Log.i("tagconvertstr", "["+result+"]");

    new JSONObject 调用之前,在解析它之前看看你得到了什么。

    编辑:如果您使用的是 Eclipse,您可以设置一个断点并逐步查看发生了什么。

    【讨论】:

    • 感谢我设法纠正了一些错误 2 ';'丢失了,我可以看到 Log.i("tagconvertstr", "["+result+"]"); 的错误显示的是这样的:
    • 我遇到了同样的情况,谁能帮帮我?
    【解决方案2】:

    感谢我设法纠正了一些错误 2 ';'丢失了,我可以看到 Log.i("tagconvertstr", "["+result+"]"); 的错误

    它显示的味精是这样的:

    [&lt;br/ &gt; font size = 1 table class=''xdebug-erroe' dir='ltr' ... loads of html code that wasn't in my initial code then....{"message":"Problem sending you the activation mail !"}]

    因此,消息“向您发送激活邮件时出现问题”的 json 格式存在问题,但用户注册成功!

    所以我第二次尝试该代码时,它会以正确的 json 格式显示:“此电子邮件已被使用”! (没有任何错误)但我仍然无法在我的 php 代码中找到错误:S

      【解决方案3】:

      尝试在打印之前阻止任何输出并将print 更改为echo

      您也可以删除关闭的?&gt; 以防止在 php 脚本之后进一步输出

      【讨论】:

        【解决方案4】:

        您应该在发回响应之前设置Content-Type 标头。

        header('Content-Type: application/json');
        print(json_encode(array("message" => $msg)));
        

        检查这个:Returning JSON from a PHP Script

          【解决方案5】:

          我也有同样的问题;我找到了简单的方法。

          在 Java 代码中只需键入 Log.e("anyText",response); 在 logCat 中它会告诉你什么是问题
