使用参数改造后的请求 [英] Retrofit post request with parameters

问题描述

我正在使用邮递员扩展名进行邮寄请求.我想用android发出相同的请求.我使用改造库来访问我的目标.但是我无法获得成功的结果.我的代码错误在哪里?

I am using postman extension for post request. I want to make same request with android. I used retrofit library for access my goal. But I can't get successful result. Where is my mistake in code ?

邮递员:

我的界面:

public interface Interfacem {

    @FormUrlEncoded
    @POST("/login")
    Call<ResponseBody> getResponse(@Field("signin[username]") String username,@Field("signin[password]")String password );
}

和改造用途:

Retrofit retrofit = new Retrofit.Builder()
                        .baseUrl("http://myurl.com")
                        .build();

                Interfacem service = retrofit.create(Interfacem.class);
                Call<ResponseBody> result =service.getResponse("myUsername","myPassword");
                result.enqueue(new Callback<ResponseBody>() {
                    @Override
                    public void onResponse(Response<ResponseBody> response) {
                        try {
                            System.out.println(response.body().string().toString());
                        } catch (IOException|NullPointerException e) {
                            e.printStackTrace();
                        }

                    }

                    @Override
                    public void onFailure(Throwable t) {
                        t.printStackTrace();
                    }
                });

推荐答案

如果使用的是 Retrofit 2.x ，请尝试如下更改Retrofit对象的版本:

if you are using Retrofit 2.x, Try to change your build of Retrofit object as below :

Retrofit retrofit = new Retrofit.Builder()
                        .baseUrl("http://myurl.com/")
                        .build();

也许下面的事情会有所帮助

maybe the things below will help

前导 /会覆盖API端点定义的末尾.从部分网址中删除/并将其添加到基本网址中将会带来预期的结果.

the leading / within the partial url overrides the end of API endpoint definition. Removing the / from the partial url and adding it to the base url will bring the expected result.

示例:

API接口

    public interface UserService {  
    @POST("/me")
    Call<User> me();}

使用 baseUrl

Build Retrofit with baseUrl

    Retrofit retrofit = Retrofit.Builder()  
    .baseUrl("https://your.api.url/v2");
    .build();

然后致电:

UserService service = retrofit.create(UserService.class);

-> 请求网址将为 https://your.api.url/me (/v2 已消失)

--> The request Url will be https://your.api.url/me (/v2 has been disapear)

专业提示

使用相对URL作为部分终结点URL，并结束您的基本网址，后跟/.

界面

public interface UserService {  
    @POST("me")
    Call<User>me();
}

使用baseURL进行改进

Retrofit retrofit = Retrofit.Builder()  
    .baseUrl("https://your.api.url/v2/");
    .build();

致电

UserService service = retrofit.create(UserService.class);

-> 请求URL将为 https://your.api.url/v2/me
