在尝试将Json字符串解析为android时,会传递HTML值.
在一天之前一切都很好,突然我的应用程序在尝试使用PHP文件获取数据库时开始崩溃.
当我检查注意到HTML值..
看看logcat

此外,当我检查浏览器中的URL时,它返回正确的Json字符串,没有任何异常或错误与byethost ..但在androID给出HTML值..
这是我的JsONfunction类

解决了！
我使用Byethost从PHP服务器检索JsON数据时遇到了同样的问题.我们只需要在http请求中添加一个cookie来传递testcookie-Nginx-module
正如理查德的answer所说：
The main problem is that Byet Host implement a simple security antibots module >named testcookie-Nginx-module
07001
在他提供的链接上,我们可以看到testcookie-Nginx-module进行了两步验证：
>第一次完成http请求时,模块返回一个JavaScript而不是我们期望的JsON.此脚本在客户端(通常是Web浏览器)上执行,并生成包含AES密钥的验证cookie.
这是我从服务器收到的脚本：
<HTML><body> <script type="text/JavaScript" src="/aes.Js" ></script> <script> function toNumbers(d){ var e=[]; d.replace(/(..)/g,function(d){ e.push(parseInt(d,16))}); return e } function toHex(){ for(var d=[],d=1==arguments.length&&arguments[0].constructor==Array?arguments[0]:arguments,e="",f=0;f<d.length;f++) e+=(16>d[f]?"0":"")+d[f].toString(16); return e.tolowerCase() } var a=toNumbers("f655ba9d09a112ffff8c63579db590b4"), b=toNumbers("98344c2eee86c3ffff90592585b49f80"), c=toNumbers("1286963467aa92ffff8323bdca0d7be9"); document.cookie="__test="+toHex(slowAES.decrypt(c,2,a,b))+"; expires=Thu, 31-Dec-37 23:55:55 GMT; path=/"; location.href="http://myserver.byethost8.com/myPHPPage.PHP?i=1"; </script> <noscript>This site requires JavaScript to work, please enable JavaScript in your browser or use a browser with JavaScript support</noscript></body>>该脚本将验证cookie添加到文档中,并将其重定向到我们实际想要访问的URL. testcookie-Nginx-module验证cookie AES密钥,并让请求到达将响应我们想要访问的JsON数据的url.
在以下http请求中,客户端将存储cookie并将其添加到跳过步骤1的请求中.
我们的AndroID应用程序解决方案
我们将通过从Web浏览器获取cookie并将其直接添加到我们的AndroID http请求中来跳过cookie生成(除非您当然希望参与生成它).
在从Web浏览器获取cookie之前,请确保使用浏览器至少访问过一次url以生成它.
>从Web浏览器获取cookie密钥.我使用谷歌浏览器：
>从浏览器右上角的Chrome菜单中,选择设置.
>在页面底部,单击显示高级设置….
>在隐私下,选择内容设置….
>选择所有cookie和网站数据….
>搜索您的网站名称.通过搜索“byethost”你会找到它.
>打开名为__test的cookie并复制内容,路径和过期的值
>在我们的AndroID应用程序上设置cookie.你的代码应该是这样的：
try { if(post == "POST") { httpClIEnt httpClIEnt = new DefaulthttpClIEnt(); httpPost httpPost = new httpPost(loginUrl); httpPost.setEntity(new UrlEncodedFormEntity(para)); httpPost.setheader("User-Agent","Mozilla/5.0 (windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.135 Safari/537.36 Edge/12.10240 "); httpPost.addheader("cookie", "__test=THE_CONTENT_OF_YOUR_cookie_HERE; expires=Thu, 31-Dec-37 23:55:55 GMT; path=/"); httpResponse httpResponse = httpClIEnt.execute(httpPost); httpentity httpentity = httpResponse.getEntity(); is = httpentity.getContent();}else if(post == "GET"){ httpClIEnt httpClIEnt = new DefaulthttpClIEnt(); String paramString = URLEncodedUtils.format(para, "utf-8"); loginUrl += "?" + paramString; httpGet httpGet = new httpGet(loginUrl); httpGet.addheader("cookie", "__test=THE_CONTENT_OF_YOUR_cookie_HERE; expires=Thu, 31-Dec-37 23:55:55 GMT; path=/"); httpResponse httpResponse = httpClIEnt.execute(httpGet); httpentity httpentity = httpResponse.getEntity(); is = httpentity.getContent();}}就是这样.现在每次应用程序发出http请求时,它都会包含cookie以传递testcookie-Nginx-module并将检索您的JsON数据.
我希望这有所帮助,并且为时不晚.
