Feature description

The QR code recognition feature can recognize QR codes when files are uploaded.

Sample code

PutObjectRequest request = new PutObjectRequest(bucket, key, srcPath);

JObject o = new JObject();
// Do not return the input image
o["is_pic_info"] = 1;
JArray rules = new JArray();
JObject rule = new JObject();
rule["bucket"] = bucket;
rule["fileid"] = "qrcode.jpg";
// Processing parameters. For rules, visit https://www.tencentcloud.com/document/product/436/54070?from_cn_redirect=1.
rule["rule"] = "QRcode/cover/<mode>";
rules.Add(rule);
o["rules"] = rules;

string ruleString = o.ToString(Formatting.None);
request.SetRequestHeader("Pic-Operations", ruleString);
// Execute the request
PutObjectResult result = cosXml.PutObject(request);
