Question

我想用GET方法发送HTTP请求，但我无法设置GET方法。这是我的代码：

try {
                URL url = new URL(path);
                conn = (HttpURLConnection) url.openConnection();

                conn.setReadTimeout(10000);
                conn.setConnectTimeout(15000);
                conn.setRequestMethod("GET");
                conn.setDoInput(true);
                conn.setDoOutput(true);
Uri.Builder builder = new Uri.Builder()
                        .appendQueryParameter("p1", "123")
                        .appendQueryParameter("p2", "123");
                String query = builder.build().getEncodedQuery();
                OutputStream os = conn.getOutputStream();
                BufferedWriter writer = new BufferedWriter(
                        new OutputStreamWriter(os, "UTF-8"));
                writer.write(query);
                writer.flush();
                writer.close();
                os.close();

                conn.connect();
                Log.e("ERROR", conn.getResponseMessage());
                Log.e("ERROR", conn.getRequestMethod());
                Log.e("ERROR", String.valueOf(conn.getResponseCode()));

            } catch (Exception e) {
                Log.e("ERROR", e.getMessage());
            }

在代码中，我设置了GET方法，但在日志中，请求方法是POST：

02-01 16:48:54.766  23799-23831/? E/ERROR﹕ Method Not Allowed
02-01 16:48:54.766  23799-23831/? E/ERROR﹕ POST
02-01 16:48:54.766  23799-23831/? E/ERROR﹕ 405

什么问题？

Answer 1

问题是

conn.setDoOutput(true);

当设置为true时，请求方法更改为POST，因为GET或DELETE不能有请求正文

Android HttpURLConnection设置GET Request方法
