我无法解析改装响应
我无法解析改装响应
提问于 2018-02-19 10:01:28
我创建了一个公共类来访问所有POJO类。当我试图解析和访问POJO变量时，我得到的是空指针异常。我真的不知道我哪里错了。有人能帮我解决这个问题吗？
CommonReponse.java
public class CommonResponse {
private Github github;
public Github getGithub() {
return github;
}
public void setGithub(Github github) {
this.github = github;
}}GithubService.java
public interface GithubService {
@GET("users/{username}")
Call<CommonResponse> getGithubUserInfo(@Path("username") String username);}Github.java // POJO
public class Github {
@SerializedName("name")
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}}GetUserInfo() // Method
private void getUserInfo() {
Retrofit retrofit = new Retrofit.Builder()
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.baseUrl("https://api.github.com/")
.build();
GithubService githubService = retrofit.create(GithubService.class);
Call<CommonResponse> call = githubService.getGithubUserInfo(mGitUserName);
call.enqueue(new retrofit2.Callback<CommonResponse>() {
@Override
public void onResponse(Call<CommonResponse> call, Response<CommonResponse> response) {
System.out.println("Response:+"+response.body().getGithub().getName());
}
@Override
public void onFailure(Call<CommonResponse> call, Throwable t) {
System.out.println("Response error:+"+t.getMessage());
}
});}日志

尝尝这个
private void getUserInfo() {
Retrofit retrofit = new Retrofit.Builder()
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.baseUrl("https://api.github.com/")
.build();
GithubService githubService = retrofit.create(GithubService.class);
Call<Github> call = githubService.getGithubUserInfo(mGitUserName);
call.enqueue(new retrofit2.Callback<Github>() {
@Override
public void onResponse(Call<Github> call, Response<Github> response) {
System.out.println("Response:+"+response.body().getName());
}
@Override
public void onFailure(Call<Github> call, Throwable t) {
System.out.println("Response error:+"+t.getMessage());
}
});}和
public interface GithubService {
@GET("users/{username}")
Call<Github> getGithubUserInfo(@Path("username") String username);}页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
