我收到特定配置文件查询的“无法解析 http 响应”异常。从日志中可以看出，数据似乎已成功读取，响应为 200 OK，但控制转到查询的 onFailure。

  1. 在此查询之前，程序成功运行突变，没有任何问题。
  2. 只有 Profile 查询会发出异常。
  3. 这个查询也在服务器上运行良好。

我的查询：

RequestHeaders requestHeaders = RequestHeaders.builder().addHeader(LoginActivity.AUTHORIZATION, bearerTokenTest).build();
        ProfileQuery profileQuery = ProfileQuery.builder().build();
        ApiClient.getMyApolloClient().query(profileQuery)
                .requestHeaders(requestHeaders)
                .enqueue(new ApolloCall.Callback<ProfileQuery.Data>() {
                    @Override
                    public void onResponse(@NotNull Response<ProfileQuery.Data> response) {

                        if (response.data() != null) {
                            Timber.e("onResponse: %s", response.data().profile()._id());
                            //processResponse(response);
                        }
                        if (!response.errors().isEmpty())
                            Timber.e("onResponse error: %s", response.errors().get(0).message());
                    }

                    @Override
                    public void onFailure(@NotNull ApolloException e) {
                        Timber.e("onFailure: %s", e.toString());
                        //processFailure();
                    }
                });

图形：

query profile($_id:ID){
    profile(_id:$_id){
        _id
        fullName
        firstName
        lastName
        email
        classDetails{
            _id
            className
            section
            subjectName
        }
        academicYear{
            startYear
            endYear
        }
    }
}

阿波罗客户端：


public class ApiClient {

    private static final String BASE_URL = "https://rf-xxxx.x.com";
    public static ApolloClient apolloClient;

    public static ApolloClient getMyApolloClient() {
        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.level(HttpLoggingInterceptor.Level.BODY);

        OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();

        apolloClient = ApolloClient.builder()
                .serverUrl(BASE_URL)
                .okHttpClient(client)
                .build();
        return apolloClient;
    }

}

毕业典礼：

buildscript {

    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" } //comment if necessary
        maven { url 'https://oss.sonatype.org/content/repositories/snapshots/' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
        classpath 'com.apollographql.apollo:apollo-gradle-plugin:1.1.3'
        classpath 'com.apollographql.apollo:apollo-gradle-plugin:1.2.0-SNAPSHOT'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

    }
}

感谢您的任何建议。

这是从堆栈跟踪中发现的 Apollo 客户端构建器中缺少“自定义日期类型适配器”的问题。

java.lang.IllegalArgumentException: Can't map GraphQL type: Date to: class java.lang.Object. Did you forget to add custom type adapter?
    at com.apollographql.apollo.response.ScalarTypeAdapters.adapterFor(ScalarTypeAdapters.java:30)
    at com.apollographql.apollo.internal.response.RealResponseReader.readCustomType(RealResponseReader.java:193)

我已将如下自定义类型适配器添加到 Apollo Client Builder 中，现在它工作正常。


public static ApolloClient getMyApolloClient() {
    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.sss'Z'", Locale.US);
    CustomTypeAdapter dateCustomTypeAdapter = new CustomTypeAdapter<Date>() {
        @Override
        public Date decode(CustomTypeValue value) {
            try {
                return dateFormat.parse(value.value.toString());
            } catch (ParseException e) {
                throw new RuntimeException(e);
            }
        }

        @Override
        public CustomTypeValue encode(Date value) {
            return new CustomTypeValue.GraphQLString(dateFormat.format(value));
        }
    };

    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.level(HttpLoggingInterceptor.Level.BODY);

    OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();

    apolloClient = ApolloClient.builder()
            .serverUrl(BASE_URL)
            .okHttpClient(client)
            .addCustomTypeAdapter(CustomType.DATE, dateCustomTypeAdapter)
            .build();
    return apolloClient;
}
