云函数REST API:从压缩文件创建新操作

Question

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:[e-mail]/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"

有没有可能获得一个如何通过RESTneneneba API从zip文件创建新操作的示例？非常感谢。

您必须base64编码您的.zip文件，然后将其作为code参数传递。我已经编写了一个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:"$ACTION", exec:{kind:"nodejs:10", code:., binary:true, main:"main"}}" | curl -X PUT -H "Content-Type:application/json"  -d @- https://USERNAME:[e-mail]/api/v1/namespaces/_/actions/$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" ]"

用于创建或更新云函数操作的REST API记录在IBM云函数API文档中。了解确切的curl/request语法的一个好方法是在详细模式(-v(中使用IBMCloudFunctionsCLI。CLI只是REST API的包装器，并且在详细模式下打印所有REST详细信息。

以下是可以打印的内容的相关部分：

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内容包含为code。curl文档建议使用@filename来引用您的zip文件：

如果希望从文件中读取内容，请使用<filename>作为目录
