我可以使用curl向浏览器模式发送请求，如下所示： curl -X PUT -d "pageRef=car" localhost:9000/proxy/8081/har/pageRef。但是，我想在nodejs中使用请求模块执行此操作。什么是使用请求模块的等效命令？我想这是一样的东西request.put(url, data, callback)但是当我尝试request.put('localhost:9000/proxy/8081/har/pageRef', {form: { pageRef: encodeURI(browser.platform) + encodeURI(browser.browserName) + encodeURI(browser.version) }})，我得到如何使用nodejs请求模块进行卷曲调用
