php - 在 Android 中将 Retrofit 发布到 Rest 服务器

Question

作为大学小组项目的一部分，我们使用 PHP rest 服务器将数据发送到 Oracle 服务器。到目前为止，所有 get 方法都工作正常，但我无法理解如何发布数据，因为它不起作用。

这是PHP

    $app->post('/room', function () use ($app) {
    $request = $app->getInstance()->request();
    $room = json_decode($request->getBody(), true);
    $sql = 'INSERT INTO rooms VALUES(null, :room_pcm, :property_id)';
    $query = oci_parse(getConnection(), $sql);
    $room_pcm = $room['ROOM_PCM'];
    $property_id = $room['PROPERTY_ID'];
    oci_bind_by_name($query, ':room_pcm', $room_pcm);
    oci_bind_by_name($query, ':property_id', $property_id);
    oci_execute($query);
});

但我一辈子都无法让它在 Android 中运行。

这是我用来发布数据的方法:

    @FormUrlEncoded
@POST("/room")
Room postRoom(Integer roomId, Double pcm, Integer propID);

从 Activity 中

    public void insertARoom(){
    RestService.INSTANCE.getService().postRoom(200, 50.0, 103);
}

它说的错误是它需要对参数 1 进行改造注释。我也尝试过使用 Property 类型的回调，但这仍然给我带来了问题。

理想情况下，第一个参数应该为 null，因为它是主键，我该怎么做？

谢谢奥马尔

其余适配器正在使用 GSON

    public Rest getService() {
    if (RestService.service == null) {
        Gson gson = new GsonBuilder().registerTypeAdapter(Image.class,
                new ImageDeserialiser()).registerTypeAdapter(CountInteger.class, new CountDeserialiser()).create();
        RestService.service = new RestAdapter.Builder()
                .setEndpoint(RestService.URL)
                .setConverter(new GsonConverter(gson)).build()
                .create(Rest.class);
    }
    return RestService.service;
}

Answer 1

为了发送您的数据，您必须使用 @Field 注释为每个参数“添加前缀”，如下所示:

@FormUrlEncoded
@POST("/room")
Room postRoom(@Field("roomId") Integer roomId, @Field("pcm") Double pcm, @Field("propID") Integer propID);
