Why Does `xml.NewDecoder()` Throw an EOF Error After Reading the HTTP Response Body?

XML Decoding Error with xml.NewDecoder() After Reading Body Content

When attempting to decode XML from a HTTP response body, developers may encounter an EOF (end-of-file) error with xml.NewDecoder(). This error typically occurs if the body content has already been read or processed.

The provided code sample includes a section where the response body is first read using ioutil.ReadAll(). This action consumes the entire body content, making it unavailable for subsequent operations. Consequently, when xml.NewDecoder() is used to read the body, it reaches the end of the file and triggers the EOF error.

To avoid this error, it is recommended to cache the response body content into a variable before performing any read operations. This allows other functions, such as xml.NewDecoder(), to access the content without triggering the EOF error.

Sample Code Modification:

<code class="go">var bodyContent []byte

resp1, err := client.Do(req1)
error_handler(err)

defer resp1.Body.Close()
bodyContent, err = ioutil.ReadAll(resp1.Body)
error_handler(err)
resp1.Body = ioutil.NopCloser(bytes.NewBuffer(bodyContent))

if err := xml.NewDecoder(resp1.Body).Decode(&amp;v); err != nil {
    fmt.Printf("error is : %v", err)
    return
}</code>
Copy after login

By introducing the bodyContent variable and updating the resp1.Body, the content can be reused for both actions. This approach eliminates the EOF error and allows for successful XML decoding.
