通过if语句进行多次赋值

Question

It is possible to execute multiple assignment by if condition, like the following code?

func SendEmail(url, email string) (string, error) {

    genUri := buildUri()
    if err := setRedisIdentity(genUri, email); err != nil; genUrl, err := buildActivateUrl(url, genUri);  {
        return "", err
    }  

    return "test", nil

}

No. Only one 'simple statement' is permitted at the beginning of an if-statement, per the spec.

The recommended approach is multiple tests which might return an error, so I think you want something like:

func SendEmail(url, email string) (string, error) {
    genUri := buildUri()
    if err := setRedisIdentity(genUri, email); err != nil {
        return "", err
    }  
    if genUrl, err := buildActivateUrl(url, genUri); err != nil {
        return "", err
    }
    return "test", nil
}
