您好我是Android新手,现在我正在使用Retrofit来集成Web服务。
我不了解如何使用Retrofit POST请求将参数发送到服务器。
请帮帮我。感谢。
String url = "XXXXXXXXX/";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Retrofit retrofit = new Retrofit.Builder().baseUrl(url).
addConverterFactory(GsonConverterFactory.create()).build();
PostInterface service = retrofit.create(PostInterface.class);
JSONObject jsonObject = new JSONObject();
try {
jsonObject.put("email", "device3@gmail.com");
jsonObject.put("password", "1234");
} catch (JSONException e) {
e.printStackTrace();
}
final String result = jsonObject.toString();
service.getStringScalar(result).enqueue(new Callback<String>() {
@Override
public void onResponse(Call<String> call, Response<String> response) {
System.out.println("result is====>" + response.body());
}
@Override
public void onFailure(Call<String> call, Throwable t) {
System.out.println("Failuere");
}
});
}
public interface PostInterface {
@POST("User/DoctorLogin")
Call<String> getStringScalar(@Body String body);
}

制作一个新的模型类:
public class Credentials {
private String email;
private String password;
public Credentials(String email, String password) {
this.email = email;
this.password = password;
}
}
然后修改你的界面:
public interface PostInterface {
@POST("User/DoctorLogin")
Call<String> getStringScalar(@Body Credentials body);
}
然后这样称呼:
service.getStringScalar(new Credentials("device3@gmail.com", "1234")).enqueue(new Callback<String>() {
@Override
public void onResponse(Call<String> call, Response<String> response) {
System.out.println("result is====>" + response.body());
}
@Override
public void onFailure(Call<String> call, Throwable t) {
System.out.println("Failuere");
}
});

public interface PostInterface {
@POST("User/DoctorLogin")
Call<JsonObject> getStringScalar(@Field("PARAMATER_ID") String body);}
您也可以使用字符串代替jsonobject,但我会建议使用json。 &#34; @Field(YOUR_PARAMETER)&#34;是你使用这个

阅读this artical这有助于您了解改造。
答案 3 :(得分:0)
创建一个模型类
public class Model {
String userName;
String password;
}
生成getter和setter
修改您的界面
public interface ApiInterface {
@FormUrlEncoded
@POST("User/DoctorLogin")
Call<Model> loadDetail(@Field("user_id") String user_id,
@Field("password") String password);
}
并像这样称呼它
Retrofit retrofit = new Retrofit.Builder()
.addConverterFactory(GsonConverterFactory.create()).baseUrl(url)
.build();
ApiInterface service = retrofit.create(ApiInterface.class);
Call<Model> call = service.loadDetail("username", "password");
call.enqueue(new Callback<Model>() {
@Override
public void onResponse(Call<Model> call, Response<Model> response) {
int statusCode = response.code();
Model user = response.body();
Log.d("userName: " user.getUserName());
Log.d("password: " + user.getPassword());
}
@Override
public void onFailure(Call<Model> call, Throwable t) {
Toast.makeText(getApplicationContext(), "data not found", Toast.LENGTH_SHORT).show();
}
