我正在尝试使用以下curl通过REST API从zip文件创建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"
是否可以获得有关如何从 zip 文件并通过 REST API 创建新操作的示例?谢谢。
最佳答案
您必须对 .zip 文件进行 base64 编码,然后将其作为 code
参数传递。我编写了一个 shell 脚本(bash)来编码并创建一个名为“action”的操作。将脚本保存为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 *
。
测试操作
ibmcloud fn action invoke --result action --param lines "[\"and now\", \"for something completely\", \"different\" ]"
