对于特定的配置文件查询，我收到“无法解析http响应”异常。从日志中可以看出，似乎已成功读取200 OK响应的数据，但控件转到查询的onFailure。

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

谢谢您的建议。

这是从堆栈跟踪中发现的Apollo Client Builder中缺少“自定义DATE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)
我已经在Apollo Client Builder中添加了以下自定义类型适配器，并且现在可以正常使用了。
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;
}
