jakarta-ee - 为什么我在尝试从 WSO2 ESB 流执行此 REST API POST 请求时收到此错误？

问题描述

我在尝试从 WSO2 ESB 流向外部 REST API 执行 HTTP POST 请求时发现了一些问题。

这是必须在我的 ESB 流程中复制的原始 cURL 调用：

curl -v -X POST -k -H "Content-type: text/plain" -d @fpma_payload.json https://us-central1-fao-gift-app.cloudfunctions.net/fpmaGetData

这是fpma_payload.json文件中包含的有效负载：

{
    "source":"pricingdata",
    "filters": {
        "country_iso3": "KGZ",
        "granularity":"daily",
        "pricing_date_from": "2018-01-01",
        "pricing_date_to": "2018-01-12",
        "commodity":["Пшеница"],
        "measureunit":["килограмм"]
   }
}

请注意，“Content-type: text/plain”是强制性的（否则调用会出错）。

另请注意，商品和度量单位字段的值包含（并且是正确的）西里尔字符。

我创建了这个执行上一个调用的 ESB API：

但是电话打不通。

我在 WSO2 上启用了有线日志来分析进出流量，并在我获得的日志中：

最后有这个错误：

HTTPS-Sender I/O dispatcher-1 >> "Error: could not handle the request[\n]" {org.apache.synapse.transport.http.wire}

查看日志可能是什么问题？我不确定执行调用的中介链是否正确，或者问题是否与西里尔字符有关（查看线路日志，发送中介似乎将这些字符翻译为：

"commodity":["[0xd0][0x9f][0xd1][0x88][0xd0][0xb5][0xd0][0xbd][0xd0][0xb8][0xd1][0x86][0xd0][0xb0]"], 
                                                                                                                                                     "measureunit":["[0xd0][0xba][0xd0][0xb8][0xd0][0xbb][0xd0][0xbe][0xd0][0xb3][0xd1][0x80][0xd0][0xb0][0xd0][0xbc][0xd0][0xbc]"]

如何尝试修复它并正确执行此 REST 调用？

解决方案

在调解员之后，您不能有任何调解send员。您可以登录outSequence并send返回对客户端的响应
