我正在尝试通过简单的Azure函数HTTPTrigger在JS上传文件,它给了我以下错误:
[Error] Exception while executing function: Functions.HttpTriggerJS1. Microsoft.Azure.WebJobs.Host: Microsoft Azure WebJobs SDK '[Hidden Credential]' connection string is missing or empty. The Microsoft Azure Storage account connection string can be set in the following ways:
1. Set the connection string named '[Hidden Credential]' in the connectionStrings section of the .config file in the following format <add name="[Hidden Credential]" connectionString="DefaultEndpointsProtocol=http|https;AccountName=NAME;AccountKey=KEY" />, or
2. Set the environment variable named '[Hidden Credential]', or
3. Set corresponding property of JobHostConfiguration.
我不确定在哪里可以找到并编辑.config文件或添加环境变量。连接字符串已添加到function.json
文件中,如下所示。
另外,我不知道只有context.bindings.outputBlob = req.body;
是否足以在content-type': 'application/octet-stream'
的存储容器中创建blob。
index.js:
module.exports = function (context, req) {
context.log('JavaScript HTTP trigger function processed a request.');
context.bindings.outputBlob = req.body;
context.res = {
// status: 200, /* Defaults to 200 */
body: "Uploaded "
};
context.done();
};
function.json
{
"bindings": [
{
"authLevel": "function",
"type": "httpTrigger",
"direction": "in",
"name": "req",
"route": "FileUploadNode/{filename}",
"methods": [
"post"
]
},
{
"type": "http",
"direction": "out",
"name": "res"
},
{
"type": "blob",
"name": "outputBlob",
"path": "CONTAINER-NAME/{filename}",
"connection": "SOME CONNECTION STRING",
"direction": "out"
}
],
"disabled": false
}
答案 0 :(得分:1)
导航至 Azure门户&gt;您的Azure功能应用&gt;平台功能&gt;应用程序设置并将存储帐户连接字符串添加为值,并将function.json文件中的 SOME CONNECTION STRING 字符串添加为名称
您可以将其添加为应用程序设置或自定义连接字符串,也可以正常使用。
