Why Am I Getting an Interface Conversion Error When Parsing Serpwow API Response?

Interface Conversion Error: Mapping Mismatch

In this code, an error is encountered while parsing the response from the serpwow API for Google search results. The error message indicates that the interface conversion has failed due to a type mismatch.

Root Cause:

The error occurs because the JSON response contains an array of results in the "organic_results" property. However, the code assumes that this property is a map, which leads to the interface conversion issue.

Solution:

To resolve this issue, update the code to correctly handle the array in the JSON response:

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

Explanation:

• response["organic_results"].([]interface{}) iterates over the elements in the "organic_results" array, each of which is an interface representing a result.
• item.(map[string]interface{}) converts the current interface to a map, which represents a specific search result.
• item.(map[string]interface{})["title"] extracts the "title" property from the result map as a string.
