使用 Json 数据改造 POST 方法得到错误代码 400:错误请求 [英] Retrofit POST Method with Json data got error code 400 : Bad Request
本文介绍了使用 Json 数据改造 POST 方法得到错误代码 400:错误请求的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想使用 JSON 数据(提供 JSON 作为 JsonObject)在 Retrofit 中调用 POST 方法(Magento REST API).为此,我从邮递员那里打电话给我,对我来说工作正常.
I would like to call a POST Method(Magento REST API) in Retrofit with a JSON data(provide JSON as JsonObject). For that, I call as follow from the postman and work fine for me.
我已经完成了android部分如下,
I have done the android parts as follow,
API 接口
public interface APIService {
@POST("seq/restapi/checkpassword")
@Headers({
"Content-Type: application/json;charset=utf-8",
"Accept: application/json;charset=utf-8",
"Cache-Control: max-age=640000"
})
Call<Post> savePost(
@Body JSONObject jsonObject
);}
APIUtility 类为
APIUtility class as
public class ApiUtils {
private ApiUtils() {
}
public static final String BASE_URL = "http://xx.xxxx.xxx.xxx/api/rest/";
public static APIService getAPIService() {
return RetrofitClient.getClient(BASE_URL).create(APIService.class);
}
}
RetrofitClient 类为
RetrofitClient class as
private static Retrofit retrofit = null;
public static Retrofit getClient(String baseUrl) {
if (retrofit==null) {
retrofit = new Retrofit.Builder()
.baseUrl(baseUrl)
.addConverterFactory(GsonConverterFactory.create())
.build();
}
return retrofit;
}
最后,调用函数如下
public void sendPost(JSONObject jsonObject) {
Log.e("TEST", "****************************************** jsonObject" + jsonObject);
mAPIService.savePost(jsonObject).enqueue(new Callback<Post>() {
@Override
public void onResponse(Call<Post> call, Response<Post> response) {
if (response.isSuccessful()) {
}
}
@Override
public void onFailure(Call<Post> call, Throwable t) {
}
});
}
使用带有主体的 POST 方法调用 Retrofit API.
CallRetrofit API with the POST method with a body.
推荐答案
将您的代码更改为这样的内容,GsonConverterFactory 会将 User 对象转换为 json 本身.
Change your code to something like this, GsonConverterFactory converts a User object to json itself.
public interface APIService {
@POST("seq/restapi/checkpassword")
@Headers({
"Content-Type: application/json;charset=utf-8",
"Accept: application/json;charset=utf-8",
"Cache-Control: max-age=640000"
})
Call<Post> savePost(@Body User user);
}
这是用户类:
public class User {
private String username;
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
