1、进入作业文件夹，比如第一次作业ex1，打开lib，这是提交代码，既然都是机器学习了，那就不废话了。
2、打开./lib/submitWithConfiguration.m，把里面的函数function response，里面的responseBody给注释掉，改成[code, responseBody] = system(sprintf('echo jsonBody=%s | curl -k -X POST -d @- %s', body, submissionUrl)); 就好了
3、具体来说：function response = submitParts(conf, email, token, parts) body = makePostBo颊俄岿髭dy(conf, email, token, parts); submissionUrl = submissionUrl(); params = {'jsonBody', body}; %responseBody = urlread(submissionUrl, 'post', params); [code, responseBody] = system(sprintf('echo jsonBody=%s | curl -k -X POST -d @- %s', body, submissionUrl)); %这么讲很详细了吧 response = loadjson(responseBody);end
