JavaScript-比较两个相同的字符串但它们不相等

Question

I use angularjs $http to send a request, for basic authorization I provided headers with 'Authorization': this.basicAuthorization

But it doesn't work, I found out that there is a problem in this.basicAuthorization . When I replace it with a string 'Basic SOME_BASE64_ENCODED_STRING'

this.basicAuthorization = 'Basic'+' '+ btoa('username'+';'+'password');
this.myString = 'Basic SOME_BASE64_ENCODED_STRING';

console.log(this.basicAuthorization + " " + typeof this.basicAuthorization + " lenght " + this.basicAuthorization.length);
console.log(this.myString + " " + typeof this.myString + " length " + this.myString.length);


if(this.basicAuthorization == this.myString){
    console.log("equal")
}
else{
    console.log('not equal');
    console.log(this.basicAuthorization + " " + typeof this.basicAuthorization + " lenght " + this.basicAuthorization.length);
    console.log(this.myString + " " + typeof this.myString + " length " + this.myString.length);

}

And what I see in a console is

not equal

Basic SOME_BASE64_ENCODED_STRING string 82

Basic SOME_BASE64_ENCODED_STRING string 82

Why are the strings are not equal and why when I use btoa() also my http request is not working and when I provide it with this.myString it works

Change:

this.basicAuthorization = 'Basic'+' '+ btoa('username'+';'+'password');

To:

this.basicAuthorization = 'Basic'+' '+ btoa('username'+':'+'password');

In basic authentication the username and password must be seperated by : . See the HTTP Authentication RFC .
