Retrofit+OkHttp can send a GET request, but gives SocketTimetout when sending a POST… here is a solution to the problem.
Retrofit+OkHttp can send a GET request, but gives SocketTimetout when sending a POST
I
started with Retrofit and I could successfully perform a GET request, but when I tried to perform a POST or PUT request, I got a SocketTimeOut exception.
I will this question OkHttp was added to my libs folder, but that didn’t fix the problem.
An interface is defined as follows:
public interface MyService {
@GET("/orders.json")
void listOrders( Callback<List<Order>> callback );
@GET("/forms.json")
void listForms( Callback<List<Form>> callback );
@POST("/orders/{id}.json")
void saveOrder( @Path("id") int orderId, @Body Order order, Callback<Order> callback );
}
This is how I perform POST requests:
private RestAdapter restAdapter;
private MyService webservice;
restAdapter = new RestAdapter.Builder()
.setEndpoint(API_URL)
.build();
webservice = restAdapter.create(MyService.class);
webservice.saveOrder( (int) _chamado.getId(), _chamado, new Callback<Order>() {
@Override
public void success(Order arg0, Response arg1) {
Toast.makeText(MyActivity.this, "Request OK", Toast.LENGTH_SHORT).show();
}
@Override
public void failure(RetrofitError arg0) {
Toast.makeText(MyActivity.this, "ERROR", Toast.LENGTH_SHORT).show();
}
} );
After executing webservice.saveOrder(...), I don’t see any requests in the server logs (although I see a log of every GET request). The reason for RetrofitError is retrofit. RetrofitError: java.net.SocketTimeoutException。
All libraries have been updated (Retrofit 1.5.0 and OkHttp 1.5.3) and I’m using a real device running Android 4.4.2.
Unlike issues reported on GitHub , this error always occurs for POST or PUT requests.
Thanks in advance!
Edit
After enabling Retrofit FULL Log, I noticed that after a PUT request, I could no longer connect to the server (even if it was a GET request). In the log below you can see a successful GET request, followed by an “obviously” successful PUT request (no hit to the server – this request has no logs at all in the server), and then another PUT request connection exception thrown. After that, even the same GET request as before is not sent to the server – and the same exception is dispatched. Any thoughts on this?
