如何将 REST API 中的 Java class 中的当前日期传递给 GraphQL API

Question

我正在尝试从我的 Springboot class 调用 graphql api。它会返回一个错误，如下所示，我知道这个问题是由于我发送到 graphql api

的日期造成的

<200,{"errors":[{"error_code":"400-900","description":"Invalid Syntax : offending token '2020' at line 1 column 204"}]},[Date:"Sun, 28 Mar 2021 11:19:05 GMT", Content-Type:"application/json;charset=UTF-8", Content-Length:"114", Connection:"keep-alive", Strict-Transport-Security:"max-age=15724800; includeSubDomains", access-control-allow-origin:"*", access-control-allow-methods:"*", access-control-max-age:"3600", access-control-allow-headers:"authorization, content-type, xxxx-token", access-control-expose-headers:"xxxx-token", vary:"Origin,Access-Control-Request-Method,Access-Control-Request-Headers", x-envoy-upstream-service-time:"3", x-envoy-decorator-operation:"<<graphql api project name>>.<<graphql api name>>.svc.cluster.local:8080/*"]>

如果我从 postman 调用同一个 graphQL，它工作正常并且数据也被插入到数据库中。邮递员正文中给出的输入如下

mutation{ createNewApplication(orgid: "test",applctnnm: "mynewappl",dispnm: "test",applfortxt: "test",crtdbytxt: "test",updtdbytxt: "test",applid: "test",loadts: "2020-06-28T16:48:37.000+0000",crtdts: "2020-06-28T16:48:37.000+0000",updtdts: "2020-06-28T16:48:37.000+0000",extrnlapplctnid: "test",isdeletedflg: true) }

我的springboot中的graphql文件api如下所示

mutation{
    createAggrgtrApplctnByOrgid(orgid: "orgid",applctnnm:  "applctnnm",dispnm: "dispnm",applfortxt: "applfortxt",crtdbytxt: "crtdbytxt",updtdbytxt: "updtdbytxt",applctnid: "applctnid",loadts: "loadts",crtdts: "crtdts",updtdts: "updtdts",extrnlapplctnid: "extrnlapplctnid",isdeletedflg: isdeletedflg)
}

我的Java文件中的代码如下

String gqlTemplate = resourceReader.asString(createAppGql);;
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern(Constants.DATE_TIME_FORMAT);
        LocalDateTime dateTime = LocalDateTime.now();
        String formattedDateTime = dateTime.format(formatter);
        return txt.replace("orgid", applicationData.getOrganizationId())
                .replace("applctnnm", applicationData.getApplicationName())
                .replace("dispnm", applicationData.getApplicationDisplayName())
                .replace("applfortxt", "")
                .replace("crtdbytxt",applicationData.getRole())
                .replace("updtdbytxt", applicationData.getRole())
                .replace("loadts", "2020-06-28T16:48:37.000+0000")
                .replace("crtdts", "2020-06-28T16:48:37.000+0000")
                .replace("updtdts", "2020-06-28T16:48:37.000+0000")
                .replace("extrnlapplctnid", applicationData.getExternalApplicationId())
                .replace("isdeletedflg", "false" ); 
HttpEntity<String> entity = new HttpEntity<>(queryTemplate, headers);
ResponseEntity<AppDataResponse> response = restTemplate.exchange(appURL, HttpMethod.POST, entity,
                    AppDataResponse.class);

请求某人帮助我解决这个问题。如何将日期从我的 java class?

传递给 graphQL api

您的 txt.replace() 没有替换 txt 字符串的正确部分。

您的 graphql 文本突变是：

mutation{
    createAggrgtrApplctnByOrgid(
        orgid: "orgid",
        applctnnm:  "applctnnm",
        dispnm: "dispnm",
        applfortxt: "applfortxt",
        crtdbytxt: "crtdbytxt",
        updtdbytxt: "updtdbytxt",
        applctnid: "applctnid",
        loadts: "loadts",
        crtdts: "crtdts",
        updtdts: "updtdts",
        extrnlapplctnid: "extrnlapplctnid",
        isdeletedflg: isdeletedflg)
}

在执行 txt.replace("updtdts", "2020-06-28T16:48:37.000+0000") 时，您将所有出现的 updtdts 替换为 2020-06-28T16:48:37.000+0000.

您的突变变为：

mutation{
    createAggrgtrApplctnByOrgid(
        orgid: "orgid",
        applctnnm:  "applctnnm",
        dispnm: "dispnm",
        applfortxt: "applfortxt",
        crtdbytxt: "crtdbytxt",
        updtdbytxt: "updtdbytxt",
        applctnid: "applctnid",
        loadts: "loadts",
        crtdts: "crtdts",
        2020-06-28T16:48:37.000+0000: "2020-06-28T16:48:37.000+0000",
        extrnlapplctnid: "extrnlapplctnid",
        isdeletedflg: isdeletedflg)
}

这是无效的，因为 2020-06-28T16:48:37.000+0000 不是有效的字段名称！您需要避免替换字段名称，而只替换值。

我还建议使用合适的 graphql 客户端库，例如 Apollo Graphql Client 而不是手动更新您的查询。
