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：

12:24:32 * Closing connection 1
