Android Retrofit | Post custom object (send json to server)
提问by FRR
I was wondering how could I go about sending a custom object to my API using retrofit, something like this:
我想知道如何使用改造将自定义对象发送到我的 API，如下所示：
@POST(URL_ORDERS)
public void newOrder(Order order, Callback<Boolean> success);
Here's how I'd parse it on my server
这是我在服务器上解析它的方式
public function store()
{
if(Auth::check()){
$order = Input::get();
$table = $order->table;
$items = $order->items;
if(!$table->taken){
$table->taken = true;
$order->push();
$table->push();
return true;
}
}
return false;
}
For some reason I'm getting
出于某种原因，我得到
06-04 20:45:59.275 6085-6306/com.tesis.restapp.restapp W/dalvikvm﹕ threadid=11: thread exiting with uncaught exception (group=0x40aae210)

at retrofit.RestMethodInfo.parseParameters(RestMethodInfo.java:443)
at retrofit.RestMethodInfo.init(RestMethodInfo.java:131)
I guess what I want it do to is to somehow transform my object into a json and send it to my server. Am I approaching this the right way?
我想我想要它做的是以某种方式将我的对象转换为 json 并将其发送到我的服务器。我是否以正确的方式接近这个？

The error is from not providing the @Bodyannotation on your Orderparameter. Change it to:
错误是由于未@Body在您的Order参数上提供注释。将其更改为：
@POST(URL_ORDERS)
public void newOrder(@Body Order order, Callback<Boolean> success);
Retrofit uses Gsonto serialize and deserialize JSON by default. Gson uses variable names by default for serialization, but they can be changed using the annotation @SerializedName("replacement_name").
Retrofit默认使用Gson对 JSON 进行序列化和反序列化。Gson 默认使用变量名进行序列化，但可以使用 annotation 更改它们@SerializedName("replacement_name")。
For Example, If your Orderclass looked like this:
例如，如果您的Order课程如下所示：
public class Order {
@SerializedName("custom_id")
private int id;
private String name;
private List<Item> items;
}
public class Item {
private int id;
private String name;
}
Then Gson would automatically serialize that to
然后 Gson 会自动将其序列化为
{
"custom_id": 1,
"name": "Hello Object",
"items": [
{
"id": 1,
"name": "Hello Item"
}
]
}
