然后我在这里设置了改造：
package com.salammedindonesia.ptsalammeddeviceindonesia.networks;
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import java.util.concurrent.TimeUnit;
import okhttp3.OkHttpClient;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
public class RetrofitConfig {
private static Retrofit setInitRetrofit() {
OkHttpClient client = new OkHttpClient.Builder()
.readTimeout(30, TimeUnit.SECONDS)
.connectTimeout(30, TimeUnit.SECONDS)
.build();
Gson gson = new GsonBuilder()
.setLenient()
.create();
return new Retrofit.Builder()
.baseUrl("http://192.168.43.103/PermohonanPenawaranHarga/Permohonan/")
.addConverterFactory(GsonConverterFactory.create(gson))
.client(client)
.build();
}
public static ApiService getInitRetrofit() {
return setInitRetrofit().create(ApiService.class);
}
}
我的Apiservice接口中有此代码：
package com.salammedindonesia.ptsalammeddeviceindonesia.networks;
import com.salammedindonesia.ptsalammeddeviceindonesia.models.AddImageBarangResponse;
import com.salammedindonesia.ptsalammeddeviceindonesia.models.AddResponse;
import java.util.List;
import okhttp3.MultipartBody;
import okhttp3.RequestBody;
import okhttp3.ResponseBody;
import retrofit2.Call;
import retrofit2.http.Field;
import retrofit2.http.FormUrlEncoded;
import retrofit2.http.GET;
import retrofit2.http.Headers;
import retrofit2.http.Multipart;
import retrofit2.http.POST;
import retrofit2.http.Part;
public interface ApiService {
@Headers({"Content-Type: application/json", "Content-Type: multipart/form-data"})
@Multipart
@POST("addImageBarang")
Call<AddResponse> uploadImageBarang(
@Part List<MultipartBody.Part> upload_image_barang
);
@FormUrlEncoded
@POST("addNewRequestPesananBarang")
Call<AddResponse> addPesananBarang(
@Field("customer_id") int customer_id,
@Field("pemesan_name") String pemesan_name,
@Field("pemesan_jabatan") String pemesan_jabatan,
@Field("pemesan_phone") String pemesan_phone,
@Field("pemesan_email") String pemesan_email
);
}
这是我的pojo：
package com.salammedindonesia.ptsalammeddeviceindonesia.models;
import lombok.Data;
@Data
public class AddResponse {
private boolean response;
}
最后，这是我使用CodeIgniter框架创建的API代码：
这是我的控制器：
<?php
/**
*
*/
class Permohonan extends CI_Controller
{
function __construct() {
parent::__construct();
$this->load->model('Permohonan_model');
$this->load->helper(array('form', 'url'));
}
public function getCustomerData() {
$data['customerData'] = $this->Permohonan_model->getCustomerData();
echo json_encode($data);
}
public function addImageBarang() {
// $permohonan_id = $this->input->post('permohonan_id');
if(!empty($_FILES['upload_image_barang']['name'])) {
$filesCount = count($_FILES['upload_image_barang']['name']);
for($i = 0; $i < $filesCount; $i++) {
$_FILES['upload_File']['name'] = $_FILES['upload_image_barang']['name'][$i];
$_FILES['upload_File']['type'] = $_FILES['upload_image_barang']['type'][$i];
$_FILES['upload_File']['tmp_name'] = $_FILES['upload_image_barang']['tmp_name'][$i];
$_FILES['upload_File']['error'] = $_FILES['upload_image_barang']['error'][$i];
$_FILES['upload_File']['size'] = $_FILES['upload_image_barang']['size'][$i];
$uploadPath = './uploadImages/BarangPesanan/';
$config['upload_path'] = $uploadPath;
$config['allowed_types'] = 'gif|jpg|png';
$this->load->library('upload', $config);
$this->upload->initialize($config);
if($this->upload->do_upload('upload_File')) {
$fileData = $this->upload->data();
// $uploadData[$i]['permohonan_id'] = implode(",", $permohonan_id);
$uploadData[$i]['image_name'] = $fileData['file_name'];
}
}
if(!empty($uploadData)) {
//Insert file information into the database
$insertImageBarang = $this->Permohonan_model->insertImageBarang($uploadData);
if ($insertImageBarang === TRUE) {
$data['response'] = true;
echo json_encode($data);
} else {
$data['response'] = false;
echo json_encode($data);
}
}
}
}
public function addNewRequestPesananBarang() {
$customer_id = $this->input->post('customer_id');
$pemesan_name = $this->input->post('pemesan_name');
$pemesan_jabatan = $this->input->post('pemesan_jabatan');
$pemesan_phone = $this->input->post('pemesan_phone');
$pemesan_email = $this->input->post('pemesan_email');
$pesananValue = array(
'customer_id' => $customer_id,
'pemesan_name' => $pemesan_name,
'pemesan_jabatan' => $pemesan_jabatan,
'pemesan_phone' => $pemesan_phone,
'pemesan_email' => $pemesan_email
);
$addNewRequestPesananBarang = $this->Permohonan_model->insertNewRequestPesananBarang($pesananValue);
if ($addNewRequestPesananBarang === TRUE) {
$data['response'] = true;
echo json_encode($data);
} else {
$data['response'] = false;
echo json_encode($data);
}
}
public function addNewCustomer() {
$customer_name = $this->input->post('customer_name');
$customer_address = $this->input->post('customer_address');
$customerValue = array(
'customer_name' => $customer_name,
'customer_address' => $customer_address
);
$addNewCustomer = $this->Permohonan_model->insertNewCustomerData($customerValue);
if ($addNewCustomer === TRUE) {
$data['response'] = true;
echo json_encode($data);
} else {
$data['response'] = false;
echo json_encode($data);
}
}
}
?>
这是我的模型：
<?php
/**
*
*/
class Permohonan_model extends CI_Model {
public function insertImageBarang($data = array()){
$insert = $this->db->insert_batch('tb_image_barang', $data);
return $insert?true:false;
}
public function insertNewRequestPesananBarang($pesananValue){
$insert = $this->db->insert('tb_permohonan_pemesanan_barang', $pesananValue);
return $insert?true:false;
}
public function insertNewCustomerData($customerValue){
$insert = $this->db->insert('tb_customer', $customerValue);
return $insert?true:false;
}
public function getCustomerData() {
return $this->db->get('tb_customer')->result();
}
}
?>
运行此应用程序后，我收到了此错误消息：
java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $
，但我认为我的JSON响应是正确的，这是我在Postman尝试过的JSON回应：
{
"response": true
}
您从JSosObject中获得了服务器的数据，然后将其保存或将其解析为刺痛，这是该错误的主要原因。请检查响应。
