Question

我正面临产品查询的解析问题。这是我的查询：

query getProducts（$ productCount：Int，$ variantsCount：Int）{
产品（第一个：$ productCount）{ 边缘{ 节点{ 标题 Variants（First：$ variantsCount）{ 边缘{ 节点{ 标题 ID 图片 { originalSrc } } } } } }}

如果我排除image { originalSrc }，则此查询工作正常。因此，图像URL解析会引起问题。其他相关信息：

ApolloClient

apolloClient = ApolloClient.builder()
                .serverUrl("https://" + SHOP_URL + "/api/graphql")
                .okHttpClient(okHttpClient)
                .defaultHttpCachePolicy(HttpCachePolicy.NETWORK_ONLY)
                .build();

在进行通话测试之前，您应该先验证通话。如果使用提供的工具来构建查询并以此方式进行测试，则使用GraphQL会容易得多。然后，一旦您开始获取数据，就将可运行的查询插入代码中以获取结果。比尝试像您一样猜测正确的呼叫结构要容易得多。

例如，此应用程序可能最有用：https://shopify-graphiql-app.shopifycloud.com/login
