我想使用OKHttp3进行POST,但它始终返回404.我的代码有什么问题吗?服务器端不断告诉我url和json是正确的.
我尝试了另一个发布网址和json,它可以正常工作,返回码200.
package com.epsfamily.www.kaipostb;
import android.os.AsyncTask;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import java.io.IOException;
import java.util.logging.Logger;
import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;
public class MainActivity extends AppCompatActivity {
OkHttpClient client = new OkHttpClient();
public static final MediaType JSON
= MediaType.parse("application/json; charset=utf-8");
String url;
// test data
String bowlingJson(String player1, String player2) {
return "{ \"deviceId\": \"1abcd\", \"buildingId\": 2, \"isRoutingOptimized\": false, \"isFromCurrentLocation\": true, \"startPoint\": 1, \"destinations\": [ 3, 4 ], \"createdAt\": \"2016-02-19T20:08:45.308Z\" } ";
}
String doPostRequest(String url, String json) throws IOException {
com.orhanobut.logger.Logger.json(json);
RequestBody body = RequestBody.create(JSON, json);
Request request = new Request.Builder()
.url(url)
.post(body)
.build();
Response response = client.newCall(request).execute();
com.orhanobut.logger.Logger.v("code: " + response.code());
return response.body().string();
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
url = "http://54.86.18.109:5080/Routing";
new PostAsync().execute();
}
public class PostAsync extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... params) {
String json = bowlingJson("Jesse", "Jake");
String postResponse = null;
try {
postResponse = doPostRequest(url, json);
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("res: " + postResponse);
return postResponse;
}
}
}
解决方法:
去这里:http://54.86.18.109:5080/Routing
你得到什么?是404.再次检查网址.
编辑:好的,它是POST,但是我仍然可以通过POST请求获得404.
