Salesforce extract files within Blob Zip File

Question

I am developing an application in Salesforce Where i get a zip file form an external server using HttpRequest.

The file i get from the server is Blob, but i don't know how to process it to extract the files i want.

Here's the code

        HttpRequest req = new HttpRequest();

       /* Here i set the HttpRequest Attributes*/

        Http http = new Http();                
        HttpResponse response = http.send(req);

        Blob file = response.getBodyAsBlob();

        /*Now i need to access: file to extract the files i want*/

Answer 1

This can be done with the Zippex library. It's open source and available here: https://github.com/pdalcol/Zippex

HttpRequest request = new HttpRequest();

/* Here set the HttpRequest Attributes */

Http http = new Http();                
HttpResponse response = http.send(request);

Blob file = response.getBodyAsBlob();

//Instantiate Zippex with zip file Blob
Zippex zip = Zippex(file);

for (String fileName : zip.getFileNames()) {    
    //Extract file
    Blob fileData = zip.getFile(fileName);
    //Process the file here
    ...
}
