英文:
Expected a string but was BEGIN_OBJECT at line 3 column 4 path $.SUCCESS
问题
我使用 Retrofit2 创建了一个 POST 请求方法，但在响应中遇到了以下问题：
预期得到一个字符串，但在第3行第4列处实际得到了一个 BEGIN_OBJECT，路径为 $.SUCCESS
响应应该是：
{
"SUCCESS" :
{
"200" : "访问已授权",
"ra" : "已批准",
"la" : "已批准",
"ch" : "已批准"
}
}
我使用了以下代码进行 POST 请求：
@POST("login")
Call<Post> createPost(@Body Post post);
以及 POJO 类：
public class Post {
private String anthony;
private String SUCCESS;
public Post(String name) {
this.anthony = name;
}
public String getSUCCESS() {
return SUCCESS;
}
}
对于方法，我使用了以下代码：
private void createPost() {
Post post = new Post("mypassword");
Call<Post> call = jsonPlaceHolderApi.createPost(post);
call.enqueue(new Callback<Post>() {
@Override
public void onResponse(Call<Post> call, Response<Post> response) {
if (!response.isSuccessful()) {
textViewResult.setText("Code: " + response.code());
return;
}
Post postResponse = response.body();
String content = "";
content += "Code: " + response.code() + "\n";
content += "S" + postResponse.getSUCCESS();
textViewResult.setText(content);
}
@Override
public void onFailure(Call<Post> call, Throwable t) {
textViewResult.setText(t.getMessage());
}
});
}
有人知道我的代码有什么问题吗？我预期能够在 "SUCCESS" 的 JSON 对象中获取响应。
英文:
I made a post request method with Retrofit2 but I encountered this problem on my response.
Expected a string but was BEGIN_OBJECT at line 3 column 4 path $.SUCCESS
The response should be
{
"SUCCESS" :
{
"200" : "access granted",
"ra" : "approved",
"la" : "approved",
"ch" : "approved"
}
}
I uses this code for the post request
@POST("login")
Call<Post> createPost(@Body Post post);
And for the POJO class
public class Post {
private String anthony;
private String SUCCESS;
public Post(String name) {
this.anthony = name;
}
public String getSUCCESS() {
return SUCCESS;
}
}
For the method I use the following code
private void createPost() {
Post post = new Post("mypassword");
Call<Post> call = jsonPlaceHolderApi.createPost(post);
call.enqueue(new Callback<Post>() {
@Override
public void onResponse(Call<Post> call, Response<Post> response) {
if (!response.isSuccessful()) {
textViewResult.setText("Code: " + response.code());
return;
}
Post postResponse = response.body();
String content = "";
content += "Code: " + response.code() + "\n";
content += "S" + postResponse.getSUCCESS();
textViewResult.setText(content);
}
@Override
public void onFailure(Call<Post> call, Throwable t) {
textViewResult.setText(t.getMessage());
}
});
}
Does anyone know what's wrong with my code? I expected to get the response inside the "SUCCESS" json object.

得分: 1
你期望在你想要的响应中，SUCCESS 是一个对象，但是你在 Post 类中将其定义为一个字符串。你应该将 SUCCESS 改为对象。
public class Post {
private String anthony;
private PostSuccess SUCCESS;
public Post(String name) {
this.anthony = name;
}
public PostSuccess getSUCCESS() {
return SUCCESS;
}
}
public class PostSuccess {
@JsonProperty("200")
private String _200;
private String ra;
private String la;
private String ch;
}
英文:
You expect SUCCESS to be an object in your wanted response but you have defined it as a String in your Post class. You should use an object for SUCCESS instead.
public class Post {
private String anthony;
private PostSuccess SUCCESS;
public Post(String name) {
this.anthony = name;
}
public PostSuccess getSUCCESS() {
return SUCCESS;
}
}
public class PostSuccess {
@JsonProperty("200")
private String _200;
private String ra;
private String la;
private String ch;
}
