Why Am I Getting

Compilation Error: "Expected Declaration, Found 'IDENT' Item" in Memcache Go API

When attempting to utilize the Memcache Go API to retrieve data from a specified key, an error message indicating "expected declaration, found 'IDENT' item" may arise. This issue occurs due to an improper syntax in variable declaration.

The provided code snippet:

import "appengine/memcache"

item := &memcache.Item {
    Key:   "lyric",
    Value: []byte("Oh, give me a home"),
}
Copy after login

utilizes the := short variable declaration syntax, which is only permitted within functions. Therefore, to resolve this issue, modify the code as follows:

Using a Function:

import "appengine/memcache"

func MyFunc() {
    item := &memcache.Item {
        Key:   "lyric",
        Value: []byte("Oh, give me a home"),
    }
    // Perform operations using the item variable
}
Copy after login

Using a Global Variable:

import "appengine/memcache"

var item = &memcache.Item {
    Key:   "lyric",
    Value: []byte("Oh, give me a home"),
}
Copy after login

By adhering to these guidelines, the compilation error will be eliminated, allowing you to successfully access the Memcache data using the defined item variable.
