Noob Gopher Help for JSON to Map

<p>Hi guys,</p> <p>New to Golang (and programming in general) - so apologies first if this is not the right place to post such queries.</p> <p>My question is what is the best way to bring in JSON code into a Golang map?</p> <p>I should also add - the JSON file is an external file, and not part of the main source { &#34;data&#34; : { &#34;field1&#34; : &#34;value1&#34;, &#34;field2&#34; : &#34;value2&#34; } }</p> <p>Any assistance, even if its links, will be appreciated.</p> <hr/>**评论：**<br/><br/>dlq84: <pre><p>I always prefer to map it to structs, so that I don&#39;t have to do type assertions and stuff like that. So in your case it would be</p> <pre><code>type MyJson struct { Data struct { Field1 string `json:&#34;field1&#34;` Field2 string `json:&#34;field2&#34;` } `json:&#34;data&#34;` } </code></pre> <p>And then you simply parse it like so:</p> <pre><code>var json MyJson json.Unmarshal(jsonByteSlice, &amp;json) // Don&#39;t forget to check for errors here. </code></pre> <p>Check out the <a href="https://golang.org/pkg/encoding/json/" rel="nofollow">json package</a> for more information</p></pre>SSJ3Vegeta: <pre><p>Your&#39;re an absolute diamond. Have an upvote :-)</p></pre>dlq84: <pre><p>Thanks, glad to help. Remember that missing fields will be empty string or 0 in case of integers, or whatever the type would be per default if you simply declared a variable. So if this is supposed to be used in production where you necessarily might not have control over the input, use any of the json validation libs out there. One example of such a lib is: <a href="https://github.com/michaeljs1990/val" rel="nofollow">https://github.com/michaeljs1990/val</a></p></pre>mwholt: <pre><p>You might like <a href="https://mholt.github.io/json-to-go/" rel="nofollow">https://mholt.github.io/json-to-go/</a> although it takes the data directly to a struct, not a map.</p></pre>Redundancy_: <pre><p>This can be a massively useful.</p></pre>
