android - 使用 Retrofit 发送 POST 参数

Question

我正在尝试通过 Retrofit 实现 POST 请求，但我猜这种方法似乎是错误的。我遵循了用于 GET 请求的步骤:

我定义了终点:

 public interface GitHubEmailAPI {

    @POST("/users/{user}")
    Call<GitHubEmail> postEmail(@Field("email") String email);
}

模型:

    public class GitHubEmail {

    @SerializedName("email")
    private String email;

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }
}

还有呼唤:

 public void postEmail (){
    GitHubEmailAPI apiService =
            ApiClient.getClient().create(GitHubEmailAPI.class);

    final Call<GitHubEmail> callEmail = apiService.postEmail
            (String.valueOf(enterEmailEt.getText()));

    callEmail.enqueue(new Callback<GitHubEmail>() {
        @Override
        public void onResponse(Call<GitHubEmail> call, Response<GitHubEmail> response) {
            testTV.setText(callEmail.toString());
        }

        @Override
        public void onFailure(Call<GitHubEmail> call, Throwable t) {
            Log.e("Email", t.toString());

        }
    });

我正在使用 github api 作为测试，不确定是否需要将访问 token 作为参数包含在请求中。

关于Retrofit，你知道一些信息......

1. Your BASE_URL must be end with / .

2. When you using @Field notation you must put @FormUrlEncoded in Your Api call.

3. When you using {user} in the API method you have to use @Path("user") String user to relate to url data .

4. Your POST method URL will be like this @POST("users/{user}").

5. When your response Callback done the actual Data inside your Response<GitHubEmail> response in this variable. You have to use response.body() to get what you get response from API CALL.

这是一个示例代码

@FormUrlEncoded
@POST("users/{user}")
Call<YourResultPojoClassHere> yourFuntionName(@Field("id") String id,@Path("user") String path);

请看下面的代码....

callEmail.enqueue(new Callback<GitHubEmail>() {
        @Override
        public void onResponse(Call<GitHubEmail> call, Response<GitHubEmail> response) {
              if (response.isSuccessful()) {
                        if (response.body().getSuccess()) 

                            Toast.makeText(ClassName.this, response.body().getMessage(), Toast.LENGTH_SHORT).show();
                        else
                            Toast.makeText(ClassName.this, response.body().getMessage(), Toast.LENGTH_SHORT).show();
                    } else 
                        Toast.makeText(ClassName.this, "Sorry for inconvince server is down", Toast.LENGTH_SHORT).show();

        }

        @Override
        public void onFailure(Call<GitHubEmail> call, Throwable t) {
                Toast.makeText(ClassName.this, "Check your Internet connection", Toast.LENGTH_SHORT).show();
            }
        }
    });
