我正在尝试使用以下curl从zip文件并通过REST API创建一个nodejs函数:
curl --request PUT --url 'https://my:credentials@openwhisk.eu-gb.bluemix.net/api/v1/namespaces/mynamespace/actions/my_action_name?overwrite=true' --header 'accept: application/json' --header 'content-type: application/json' --data '{"annotations":[{"key":"exec","value":"nodejs:10"},{"key":"web-export","value":true}],"exec":{"kind":"nodejs:10","init":"./action.zip"},"parameters":[{"key":"message","value":"Hello World"}]}'
结果我得到一个错误:
"error":"The request content was malformed:\n'code' must be a string or attachment object defined in 'exec' for 'nodejs:10' actions"
是否可以通过示例从zip文件以及通过REST API创建新动作的示例?谢谢。

您必须对.zip文件进行 base64编码,然后将其作为code
参数传递。我已经编写了一个shell脚本(bash)进行编码,还创建了一个名为“ action ”的操作。将脚本另存为create.sh
并执行脚本./create.sh
#!/bin/sh
ACTION=action
ZIP=$ACTION.zip
base64 $ZIP | echo "\"$(cat)\"" | jq "{namespace:\"_\", name:\"$ACTION\", exec:{kind:\"nodejs:10\", code:., binary:true, main:\"main\"}}" | curl -X PUT -H "Content-Type:application/json" -d @- https://USERNAME:PASSWORD@openwhisk.ng.bluemix.net/api/v1/namespaces/_/actions/$ACTION?overwrite=true
完整代码
app.js或index.js代码
function myAction(args) {
const leftPad = require("left-pad")
const lines = args.lines || [];
return { padded: lines.map(l => leftPad(l, 30, ".")) }
}
exports.main = myAction;
package.json
{
"name": "node",
"version": "1.0.0",
"description": "",
"main": "app.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC",
"dependencies": {
"left-pad" : "1.1.3"
}
}
运行npm install
并压缩文件zip -r action.zip *
。
测试动作
ibmcloud fn action invoke --result action --param lines "[\"and now\", \"for something completely\", \"different\" ]"

REST API for creating or updating a Cloud Functions actions is documented中的IBM Cloud Functions API docs。找出确切的curl / request语法的一种好方法是在详细模式(-v
)中使用IBM Cloud Functions CLI。 CLI只是REST API的包装,在详细模式下,所有REST详细信息都会打印出来。
以下是可打印内容的相关部分:
Req Body
Body exceeds 1000 bytes and will be truncated
{"namespace":"_","name":"mytest/myaction","exec":{"kind":"nodejs:8","code":"UEsDBBQAAAAIAHJPhEzjlkxc8wYAAH8VAAALABwAX19tYWluX18ucHlVVAkAA+iFxFrohcRadXgLAAEE9AEAAAT0AQAAxVhtb9s2EP6uX8HRCCLBipb002DA69YkbYo17dZ0GwbDMGSKlrXJokfSToNh/313R+rNL2labJiK1iJ578/x7tTBgJ7A/QzYq8IuN3NmdbpYFIIZm9rC2EKYmiIYsB+1ynW6Ykqz1y9u2WWpNhl7uamELVTFrGJClaUUtha2LeQ9S6uMiVJVspYNgnDPWKVhb5lalqU2ZUXFUqZlmaKwtKTNeWpkzKp0JcsHdj
您需要将binary
字段设置为true,并将zip内容包括为code
。 curl docs建议使用@filename引用您的zip文件:
如果要从文件读取内容,请使用<@filename>作为 内容。
