JSON错误“java.lang.IllegalStateException:期望的BEGIN_OBJECT,但在第1行第1列路径$”STRING“ [英] JSON Error "java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $"
问题描述
public interface UserService {
@POST(Constants.Api.URL_REGISTRATION)
@FormUrlEncoded
BaseWrapper registerUser(@Field(first_name)String firstname,@Field(last_name)String lastname,@Field(regNumber)String phone,@Field(regRole)int role);
$ b $ public BaseWrapper registerUser(User user){
return getUserService()。registerUser(user.getFirstName(),user.getLastName(),user.getPhone(),user .getRole());
}
这个创建异常
com.google.gson.JsonSyntaxException:java.lang.IllegalStateException:预期的BEGIN_OBJECT,但是在第1行第1列路径中为STRING $
非常感谢您的帮助。
让我们来看看您收到的错误。
期望的BEGIN_OBJECT
您的JSON是一个对象,并且所有JSON对象都用大括号({})括起来。 BEGIN_OBJECT因此是{。
但是是STRING
$ b $但是他却发现了一个字符串Something。还没有告诉我们在哪里。
at line 1 column 1 path $
啊,完美。在第1行第1列。哪个是JSON的开始。所以你忘了把所有东西都放在{}中(或者至少你已经忘记了第一个,但我敢打赌你们都忘记了它们)。
public interface UserService {
@POST(Constants.Api.URL_REGISTRATION)
@FormUrlEncoded
BaseWrapper registerUser(@Field("first_name") String firstname, @Field("last_name") String lastname, @Field("regNumber") String phone, @Field("regRole") int role);
public BaseWrapper registerUser(User user) {
return getUserService().registerUser(user.getFirstName(), user.getLastName(), user.getPhone(), user.getRole());
}
This create Exception
com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $
Big thanks for help.
Let's look at the error you are receiving.
Expected BEGIN_OBJECT
Your JSON is an object, and all JSON objects are enclosed in curly braces ({}). BEGIN_OBJECT is therefore {. And it's expecting it somewhere.
but was STRING
But instead he found a string "Something". Still doesn't tell us where.
at line 1 column 1 path $
Ah, perfect. At line 1 column 1. Which is the start of the JSON. So you have forgotten to enclose the whole thing in {} (or at least you have forgotten the first one, but I bet you've forgotten them both).
