推荐答案

基本上该错误消息是正确的，您不能使用 http:组件提供基于HTTP的终结点，用于消耗外部HTTP资源"，然后在下一节中指出"您只能 >产生到由HTTP组件生成的端点.因此，永远不要将其用作骆驼路线的输入."

Basically the error message is correct, you cannot use the http component as a consumer. However the documentation is kind of unhelpful. The first line says "The http: component provides HTTP based endpoints for consuming external HTTP resources" but then in the next section it states "You can only produce to endpoints generated by the HTTP component. Therefore it should never be used as input into your camel Routes."

一种方法是使用诸如"direct"或"quartz2"组件之类的东西作为使用者，然后在生产者中使用"http"组件.例如，此路由将每分钟运行一次，提交到指定的URL并使用带时间戳的文件名将响应保存在/tmp中:-

One approach would be to use something like the 'direct' or 'quartz2' components as the consumer, then use the 'http' component in a producer. For example, this route will run every minute, submit to the URL specified and save the response in /tmp with a timestamped filename :-

<route id="httpFetch">
    <from uri="quartz2://httpFetch?cron=00+/1+*+?+*+1-5" />
    <to uri="http://gatest.dnb.com/daasaccess/scripts/broker.asp?request=%3C%3Fxml+version%3D%271.0%27+encoding%3D%27UTF-8%27%3F%3E%3CDGX%3E%3CSIGNONMSGSRQV1%3E%3CSONRQ%3E%3CDTCLIENT%3E2007-05-04%3C%2FDTCLIENT%3E%3CUSERID%3Esalesautomation%3C%2FUSERID%3E%3CUSERPASS%3ESFAAdmin%3C%2FUSERPASS%3E%3CLANGUAGE%3EEN%3C%2FLANGUAGE%3E%3CFI%3E%3CORG%3EDandB%3C%2FORG%3E%3C%2FFI%3E%3CAPPID%3EXML%3C%2FAPPID%3E%3CAPPVER%3E0010%3C%2FAPPVER%3E%3C%2FSONRQ%3E%3C%2FSIGNONMSGSRQV1%3E%3CCREDITMSGSRQV2%3E%3CDATATRNRQ%3E%3CTRNUID%3E2D995FE0173B2C%3C%2FTRNUID%3E%3CDATARQ%3E%3CSRVRTID%3E%3C%2FSRVRTID%3E%3CSVC_TYPE_CD%3E%3C%2FSVC_TYPE_CD%3E%3CREAS_CD%3E%3C%2FREAS_CD%3E%3CCUST_ENDR%3E%3C%2FCUST_ENDR%3E%3CCUST_RQ%3E%3C%2FCUST_RQ%3E%3CREFRESH_IND%3E%3C%2FREFRESH_IND%3E%3CIGNORE_REQD_FLDS_IND%3E%3C%2FIGNORE_REQD_FLDS_IND%3E%3CSUBJ_DET%3E%3CDUNS_NBR%3E829654420%3C%2FDUNS_NBR%3E%3CCTRY_CD%3E%3C%2FCTRY_CD%3E%3CTRD_UP_IND%3E%3C%2FTRD_UP_IND%3E%3CPRIM_NME%3E%3C%2FPRIM_NME%3E%3CBUS_REGN_NBR%3E%3C%2FBUS_REGN_NBR%3E%3CBUS_REGN_NBR_TYPE_CD%3E%3C%2FBUS_REGN_NBR_TYPE_CD%3E%3CADR_LINE%3E%3C%2FADR_LINE%3E%3CPOST_TOWN%3E%3C%2FPOST_TOWN%3E%3CPRIM_GEO_AREA%3E%3C%2FPRIM_GEO_AREA%3E%3CPOST_CODE%3E%3C%2FPOST_CODE%3E%3CTLCM_NBR%3E%3C%2FTLCM_NBR%3E%3C%2FSUBJ_DET%3E%3CPROD%3EEnterprise+Management%3C%2FPROD%3E%3CPROD_TYPE_CD%3ED%3C%2FPROD_TYPE_CD%3E%3CDELV_REQS_NOW%3E%3CDELV_MODE_CD%3EDIRECT%3C%2FDELV_MODE_CD%3E%3CDELV_FMT_CD%3EXML%3C%2FDELV_FMT_CD%3E%3CLANG%3EEN%3C%2FLANG%3E%3CDELV_EMAIL%3E%3C%2FDELV_EMAIL%3E%3CDELV_EMAIL_CC%3E%3C%2FDELV_EMAIL_CC%3E%3C%2FDELV_REQS_NOW%3E%3CDELV_REQS_INV%3E%3CDELV_MODE_CD%3E%3C%2FDELV_MODE_CD%3E%3CDELV_FMT_CD%3E%3C%2FDELV_FMT_CD%3E%3CLANG%3E%3C%2FLANG%3E%3CDELV_EMAIL%3E%3C%2FDELV_EMAIL%3E%3CDELV_EMAIL_CC%3E%3C%2FDELV_EMAIL_CC%3E%3C%2FDELV_REQS_INV%3E%3CDELV_REQS_NTFY%3E%3CDELV_MODE_CD%3E%3C%2FDELV_MODE_CD%3E%3CDELV_FMT_CD%3E%3C%2FDELV_FMT_CD%3E%3CLANG%3E%3C%2FLANG%3E%3CDELV_EMAIL%3E%3C%2FDELV_EMAIL%3E%3CDELV_EMAIL_CC%3E%3C%2FDELV_EMAIL_CC%3E%3C%2FDELV_REQS_NTFY%3E%3C%2FDATARQ%3E%3C%2FDATATRNRQ%3E%3C%2FCREDITMSGSRQV2%3E%3C%2FDGX%3E"/>
