使用 Apollo 客户端购物 "Failed to parse http response"

Question

我在产品查询时遇到解析问题。这是我的查询：

query getProducts($productCount: Int, $variantsCount: Int) {
products(first: $productCount) { edges { node { title variants(first: $variantsCount) { edges { node { title id image { originalSrc } } } } } } } }

如果我排除 image { originalSrc }，此查询工作正常。所以图像 URL 解析导致了问题。其他相关信息：

ApolloClient

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

在使用调用进行测试之前，您应该先验证您的调用。如果您使用提供的工具来构建查询并以这种方式测试它们，那么使用 GraphQL 会容易得多。然后，一旦您开始取回数据，将工作查询插入您的代码以获得结果。比像你这样猜测正确的调用结构要容易得多。
