This article mainly introduces "how to use Java to print out all the posts posted by a certain user". In daily operation, I believe that many people have doubts about how to use Java to print out all the posts posted by a certain user. Xiaobian consulted all kinds of materials and sorted out simple and useful methods of operation. I hope it will be helpful to answer the doubts of "how to use Java to print out all the posts posted by a certain user". Next, please follow the editor to study!

The code is as follows:

A {color: green; font-family: arial; font-weight: bold} / * this warning means that the requested resource may be blocked by (extension / or some other mechanism). The reason for this warning is that the request to get the resource did not really happen, so the false information is displayed in Header, and the Header information will not be updated to real until the server does return a response. However, this may not happen because the request may be blocked. For example, AdBlock and so on, of course, not all browser extensions, specific analysis of the specific situation. By the way, don't forget to use chrome://net-internals to help you find blocked requests and possible reasons. * / var PREFIX = "http://tieba.baidu.com";var START =" http://tieba.baidu.com/i/i/my_tie";//var START = "http://www.baidu.com";var POST = {}; var TOTAL = 0 function getTotalCount SORTED = []; function getTotalCount (collection) {var count = 0; for (bar in collection) {if (! collection.hasOwnProperty (bar) continue; var postList = collection [bar]) Count + = postList.length;} return count;} function shouldEnd (previousCount) {TOTAL = getTotalCount (POST); console.log ("pre:" + previousCount + "total:" + TOTAL); return (previousCount = = TOTAL);} function main () {var html = getPostByAJAX (START); handleLiChildren (html); var page = 2; while (1) {var prevCount = getTotalCount (POST) Var task = START + "? & pn=" + page; var html = getPostByAJAX (task); handleLiChildren (html); page++; / * if (page > = 2) break;*/ if (shouldEnd (prevCount)) break;} sort (); generate ();} function handleLiChildren (resultString) {var htmlDom = $(resultString) Var liChildren = $("li", htmlDom); $.each (liChildren, function (I, value) {/ / if (value.className.indexOf ("nav_item")! =-1) if (value.className) return true; if (value.innerText = "my reply" | | value.innerText = = "my boutique") return true; var detail = parseDetail (value) InsertPost (detail);});} / * 2016 urea nitrogen 2015 urea nitrogen 2 * / function getpostSource (post) {var source = ""; source + = post.date + "/"; source + =''+ post.postTitle + ""; return source;} function getBarPostsSource (barName, posts) {var source =''+ barName +':'+ posts.length +'' Source + = ""; for (var I = 0; I < posts.length; iTunes +) {var post = posts [I]; source + = getpostSource (post);} source + = ""; return source;} function sortNumber (aQuery b) {return b.size-a.size;} function sort () {for (barName in POST) {if (!
