问题描述

这是我的 POST 请求。

curl -v -k -H "Content-Type:application/json" -b /tmp/zen.cookies -X POST https://${WEB_URL}/zen-data/v2/serviceInstance -d 
{"serviceInstanceNamespace":"${namespace}","serviceInstanceVersion":"1.3.5","createArguments":{"parameters":{"global.icp4Data":"true","global.pvc.pvProvisioning":"NamedStorageClass","global.filebeat.output.logstashEnabled":"false","global.filebeat.output.consoleEnabled":"true","metadata.storageClass":\\"${storageclass}\\","imagePullSecrets":"ownerServiceInstanceUsername":""},"transientFields":{}}

它给了我这个错误:

{"code":400,"message":"parsing body body from \"\" failed, because invalid character 's' looking for beginning of value"}* Could not resolve host: serviceInstanceDisplayName; Unknown error
12:24:32 * Closing connection 1
12:24:32 curl: (6) Could not resolve host: serviceInstanceDisplayName; Unknown error
12:24:33 * Could not resolve host: serviceInstanceNamespace; Unknown error

解决方案


要在 POST 命令中替换 JSON 中的变量,您需要执行以下操作:

"'"${variableName}"'"

单引号内的双引号在双引号内。所以它看起来像这样:

 curl -X POST www.example.com -d '{"country": "city","province":"'"${variableName}"'"}'
