我从Retrofit开始，我可以成功执行GET请求，但是当我尝试执行POST或PUT请求时，我得到一个SocketTimeOut异常。
我根据this question将OkHttp添加到我的libs文件夹中，但它没有解决问题。
这是界面定义：
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 );
}
这就是我执行POST请求的方式：
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();
}
} );
执行webservice.saveOrder(...)后，我在服务器日志中看不到任何请求（我看到每个GET请求的日志）。 RetrofitError的原因是retrofit.RetrofitError: java.net.SocketTimeoutException。
所有库都已更新（Retrofit 1.5.0和OkHttp 1.5.3），我正在使用运行Android 4.4.2的真实设备。
与GitHub上报告的问题不同，对于POST或PUT请求，此错误始终。
提前致谢！

启用Retrofit FULL Log后，我注意到在PUT请求之后，我无法再连接到服务器（即使是GET请求）。在下面的日志中可以看到一个成功的GET请求，接下来是一个“显然”成功的PUT请求（没有命中服务器 - 根本没有服务器中的日志），然后另一个PUT请求抛出一个ConnectException。之后，即使是相同的先前GET请求也不会被发送到服务器 - 并调度相同的异常。有什么想法吗？
