Question

我正在使用slim框架实现Retrofit，但它无法正常工作。

当我使用chrome中的邮递员测试我的Web api（PHP超薄代码）时，它工作正常，并且在Android端数据传递URL，我也可以在logcat中看到。这是我的代码。

    <?php
$app->post('/directorder',function($request) {

    require_once('dbconnect.php');

    $query = "INSERT INTO  direct_order (d_name,d_contact,d_address) values (?,?,?)";
    $stmt = $mysqli->prepare($query);
    $stmt->bind_param("sss",$a,$b,$c);


        $a = $request->getParsedBody()['d_name'];
        $b = $request->getParsedBody()['d_contact'];
        $c = $request->getParsedBody()['d_address'];

    if ($stmt->execute()) { 
            echo json_encode("success");
        } else {
            echo json_encode("fail");
        }
});

?>

这是我的Android Side COde

活性

    public class DirectOrderActivity extends AppCompatActivity {

    EditText name,contact,address;
    Button buttonUpload;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_direct_order);

        name = (EditText) findViewById(R.id.input_name);
        address = (EditText) findViewById(R.id.input_address);
        contact = (EditText) findViewById(R.id.input_contact);
        buttonUpload = (Button) findViewById(R.id.btn_directorder);

        buttonUpload.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String ename=name.getText().toString();
                String eaddress=address.getText().toString();
                String econtact=contact.getText().toString();

                RestAdapter adapterCity = new RestAdapter.Builder()
                        .setEndpoint(Base.Base_Url)
                        .setLogLevel(RestAdapter.LogLevel.FULL)
                        .build();

                UserInterface services = adapterCity.create(UserInterface.class);
                services.directorder(ename , econtact,eaddress , new Callback<String>() {
                    @Override
                    public void success(String s, Response response) {
                        Toast.makeText(getApplicationContext(), "Order Successfully", Toast.LENGTH_LONG).show();
                        Intent intent = new Intent(getApplicationContext() , MainActivity.class);
                        startActivity(intent);
                    }

                    @Override
                    public void failure(RetrofitError error) {

                    }
                });



            }
        });

    }
}

您应该发回正确的HTTP状态代码以确定失败。这是在Slim中通过返回您的路由可调用的$响应来完成的。

即。代码应该看起来像这样：

$app->post('/directorder',function($request) {

    require_once('dbconnect.php');

    $query = "INSERT INTO  direct_order (d_name,d_contact,d_address) values (?,?,?)";
    $stmt = $mysqli->prepare($query);

    $a = $request->getParsedBody()['d_name'];
    $b = $request->getParsedBody()['d_contact'];
    $c = $request->getParsedBody()['d_address'];
    $stmt->bind_param("sss",$a,$b,$c);


    if ($stmt->execute()) {
        $statusCode = 200;
        $output['result'] = 'success';
    } else {
        $statusCode = 500;
        $output['result'] = 'fail';
    }

    return $response->withJson($output, $statusCode);
});

请注意，如果您使用withJson，可以让Slim对JSON进行编码并为您设置正确的Content-Type标头，这会让生活变得更轻松。
