How to Fix an Interface Conversion Error When Parsing Google Search Results?

Interface Conversion Error in Parsing Google Search Results

Problem:

While building a project that parses Google search results using the serpwow API, an error is encountered:

panic: interface conversion: interface {} is []interface {}, not map[string]interface {}.

The error suggests a mismatch between the expected and actual data types while accessing the "organic_results" field.

Cause:

The error occurs because "organic_results" is an array in the JSON response from the API, not a map as the code assumes.

Solution:

To resolve the error, the code needs to treat "organic_results" as an array and iterate over its elements to extract the desired data. Here's the corrected code:

<code class="go">for _, item := range response["organic_results"].([]interface{}) {
    fmt.Sprintf("%v", item.(map[string]interface{})["title"])
}</code>

This code iterates over the "organic_results" array and accesses the "title" field for each result, which is a map of key-value pairs.
