我们在测试tourguide应用程序时发现了一个问题https://github.com/Fiware/tutorials.TourGuide-App.
如果我们试图从餐厅获得属性值：
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'
我们得到了预期的属性值：
{"reviewCount":1,"ratingValue":3}
但是，如果我们尝试按照更新属性值的说明更新值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}'
我们得到一个404错误。
如果我们遵循API食谱中更新属性的详细说明，则为JSONhttp://fiware.github.io/context.Orion/api/v2/cookbook/
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}}'
我们还得到一个404错误。
复制步骤：
- 克隆tourguide存储库
- 部署docker容器：
cd fiware-devguide-app/docker/compose和docker-compose -f docker-compose.yml up - 获取令牌，如下所述：https://github.com/Fiware/tutorials.TourGuide-App#how-检索oauth令牌以使用api
- 执行指定的请求
关于orion版本的信息：
<orion>
<version>0.28.0</version>
<uptime>0 d, 1 h, 12 m, 25 s</uptime>
<git_hash>aaf8020a5de680b6d7e0c00c70cf425bcc4f39c8</git_hash>

<compiled_by>root</compiled_by>
<compiled_in>838a42ae8431</compiled_in>
</orion>
已更新
为了使用Docker上提供的Orion CB的最后一个版本，我们更新了tourguide应用程序的Docker组件，但也出现了同样的错误。
这是关于最后一个版本的信息：
{
"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上下文代理，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"Elizalde"），但没有成功。对我来说效果很好。。。
首先，下面一行：
/v2/Entities/Elizalde/attrs/aggregateRating/value?Type=Restaurant
不正确。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Type被忽略，并且类型不存在，因此PUT将攻击所有名为Elizalde的实体，而不管它们的类型如何。你可能只有一个，所以没关系。如果你有不止一个名为Elizalde的实体，你会得到一个409（冲突）作为响应，但事实并非如此，因为你看到的是一个404（未找到）。
我不知道你为什么得了404分。在我的简单测试中，一切都正常（我使用的是最新版本的broker，但这不会真正改变任何事情）。
为了尝试解决您的问题，我建议您以详细模式启动代理（使用-t0-255 -logLevel DEBUG），并在收到失败的PUT请求时发布代理的输出。
此外，为了缩小范围，你可能想使用我组装的脚本在我的机器中测试它（希望它在你的机器中失败——对我来说它是有效的）：
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
启动此测试之前，请先清理数据库。
[如果您在步骤04中将type=Restaurant更改为type=Restau餐厅，您应该会看到一个409，因为有两个实体的id为Elizalde]
