[SOLVED] How to make HTTP Patch request to raven db server using golang?

How to make HTTP Patch request to raven db server using golang?

I have written the following code to add a title field to the document 1 in my raven database.

url := "http://localhost:8083/databases/drone/docs/1"
fmt.Println("URL:>", url)

var jsonStr = []byte(`{"title":"Buy cheese and bread for breakfast."}`)
req, _ := http.NewRequest("PATCH", url, bytes.NewBuffer(jsonStr))
req.Header.Set("X-Custom-Header", "myvalue")
req.Header.Set("Content-Type", "application/json")

client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
    panic(err)
}
defer resp.Body.Close()

body, _ := ioutil.ReadAll(resp.Body)
fmt.Println("response Body:", string(body))

I don't understand why it is not working? I am getting the following response Body which is not what I am expecting. I am expecting a success response.

<html>
<body>
    <h1>Could not figure out what to do</h1>
    <p>Your request didn't match anything that Raven knows to do, sorry...</p>
</body>

Can someone please point out what am I missing in the above code?

Solution

For PATCH request, you need to pass an array with patch commands (in json format) to execute.

To change the title attribute, it will look like:

var jsonStr = []byte(`[{"Type": "Set", "Name": "title", "Value": "Buy cheese and bread for breakfast."}]`)
