Question

我们在测试导游应用https://github.com/Fiware/tutorials.TourGuide-App时发现了一个问题。

如果我们尝试从餐馆获取属性值：

curl  <cb_host>:<cb_port>/v2/Entities/Elizalde/attrs/aggregateRating/value -s -S --header 'Content-Type: application/json' --header 'x-auth-token:<token>' --header 'Fiware-service: tourguide'

我们按预期获得属性值：

{"reviewCount":1,"ratingValue":3}

但是，如果我们尝试按照更新说明更新属性值http://fiware.github.io/context.Orion/api/v2/：

curl -v -X PUT <cb_host>:<cb_port>/v2/Entities/Elizalde/attrs/aggregateRating/value?Type=Restaurant -s -S --header 'Content-Type: application/json' --header 'x-auth-token:<token>' --header 'Fiware-service: tourguide' -d '{"reviewCount": 1,"ratingValue": 10}'

我们收到404错误。

如果我们按照API菜谱http://fiware.github.io/context.Orion/api/v2/cookbook/中的JSON更新属性的详细说明进行操作

curl -v -X PUT <cb_host>:<cb_port>/v2/Entities/Elizalde/attrs/aggregateRating/value -s -S --header 'Content-Type: application/json' --header 'x-auth-token:<token>' --header 'Fiware-service: tourguide' -d '{"value": {"reviewCount": 1,"ratingValue": 10}}'

我们也收到404错误。

复制步骤：

克隆导游资料库。
部署docker容器：cd fiware-devguide-app/docker/compose和docker-compose -f docker-compose.yml up
按照此处的说明获取令牌：https://github.com/Fiware/tutorials.TourGuide-App#how-to-retrieve-an-oauth-token-to-use-the-api
执行指定的请求。

有关猎户座版的信息：

<orion>
   <version>0.28.0</version>
    <uptime>0 d, 1 h, 12 m, 25 s</uptime>
    <git_hash>aaf8020a5de680b6d7e0c00c70cf425bcc4f39c8</git_hash>
    <compile_time>Mon Mar 21 13:20:37 UTC 2016</compile_time>
    <compiled_by>root</compiled_by>
    <compiled_in>838a42ae8431</compiled_in>
</orion>

更新

为了使用Docker上提供的Orion CB的最新版本，我们更新了tourguide应用程序的docker-compose，我们也遇到了相同的错误。

这是有关上一版本的信息：

{
  "orion" : {
  "version" : "1.0.0-next",
  "uptime" : "0 d, 0 h, 8 m, 20 s",
  "git_hash" : "9a35f04739a4236711bdf5b48152eaa21c3377b2",
  "compile_time" : "Wed Apr 20 11:41:57 UTC 2016",
  "compiled_by" : "root",
  "compiled_in" : "838a42ae8431"
 }
}

我们已经在调试模式下执行了Context Broker，如果我们执行：

curl -v -X PUT orion:1026/v2/Entities/Elizalde/attrs/aggregateRating/value?type=Restaurant -s -S --header 'Content-Type: application/json' --header 'x-auth-token:HuUUHhQ6Qh8myI3o3uI2rYeOIK1Ym1' --header 'Fiware-service: tourguide' -d '{"reviewCount": 1,"ratingValue": 10}'

我们得到这个输出：

我试图在有限的环境中重现您的问题（只是创建实体＆＃39; Elizalde＆＃39;）但没有成功。对我来说它很好......

首先，以下一行：
/v2/Entities/Elizalde/attrs/aggregateRating/value?Type=Restaurant 是不正确的。它必须是.../value?type=Restaurant，因为URI参数区分大小写。

使用Type而不是type意味着忽略Type并且type不存在，因此PUT将攻击称为Elizalde的所有实体，无论其类型如何。你可能只有一个，所以“好的”＃39;如果您有多个名为Elizalde的实体，那么您将获得409（冲突）作为响应，而这不是您的情况，因为您看到404（未找到）。

现在，我不知道你为什么会得到404.在我的简单测试中，一切正常（我使用的是经纪人的最新版本，但这不应该改变任何东西）。

为了尝试解决您的问题，我建议您让代理以详细模式启动（使用-t0-255 -logLevel DEBUG）并在收到失败的PUT请求时发布代理的输出。

另外，为了缩小范围，您可能希望使用我放在一起的脚本在我的机器上测试它（希望它在您的机器中失败 - 对我来说它有效）：

echo "01. Create Entity Elizalde, type Restaurant, with compound attribute 'aggregateRating'"
echo "======================================================================================"
curl -X POST localhost:1026/v2/Entities  -s -S --header 'Content-Type: application/json' --header 'x-auth-token:<token>' --header 'Fiware-service: tourguide' -d '{"id": "Elizalde", "type": "Restaurant", "aggr\
egateRating": { "value": { "reviewCount": 1, "ratingValue": 10 }}}'
echo
echo

echo "02. Create Entity Elizalde, type Restaurant2, with compound attribute 'aggregateRating'"
echo "======================================================================================"
curl -X POST localhost:1026/v2/Entities  -s -S --header 'Content-Type: application/json' --header 'x-auth-token:<token>' --header 'Fiware-service: tourguide' -d '{"id": "Elizalde", "type": "Restaurant2", "agg\
regateRating": { "value": { "reviewCount": 1, "ratingValue": 10 }}}'
echo
echo

echo "03. Get Entity Elizalde, see ratingValue == 10"
echo "=============================================="
curl localhost:1026/v2/Entities/Elizalde?type=Restaurant
echo
echo

echo "04. Change value of aggregateRating, setting ratingValue to 20 (was 10)"
echo "======================================================================="
curl -X PUT localhost:1026/v2/Entities/Elizalde/attrs/aggregateRating/value?type=Restaurant -s -S --header 'Content-Type: application/json' --header 'x-auth-token:<token>' --header 'Fiware-service: tourguide'\
 -d '{"reviewCount": 1,"ratingValue": 20}'
echo
echo

echo "05. Get Entity Elizalde, see ratingValue == 20"
echo "=============================================="
curl localhost:1026/v2/Entities/Elizalde?type=Restaurant
echo
echo

echo "06. Delete Elizalde, type Restaurant"
echo "===================================="
curl -X DELETE localhost:1026/v2/Entities/Elizalde?type=Restaurant
echo
echo

echo "07. Delete Elizalde, type Restaurant2"
echo "====================================="
curl -X DELETE localhost:1026/v2/Entities/Elizalde
echo
echo

echo "08. Intent to Get Entity Elizalde - nothing found"
echo "================================================="
curl localhost:1026/v2/Entities/Elizalde
echo
echo

在开始此测试之前清理数据库。

[如果您在步骤04中更改类型=餐馆 类型=餐馆，则应该看到409，因为有两个实体ID为Elizalde]

我使用的经纪人版本是：

"version" : "1.0.0-next",
"uptime" : "0 d, 0 h, 54 m, 42 s",
"git_hash" : "70cc445d0555cbed50134452ae9858a7ddc05d7e",
"compile_time" : "Wed Apr 20 12:35:23 CEST 2016",
"compiled_by" : "kz",
"compiled_in" : "hoppe"

git hash：70cc445d0555cbed50134452ae9858a7ddc05d7e
