折腾:
【未解决】Python代码模拟google翻译把中文翻译为英文
期间,本以为已经写好模拟google翻译的python代码了。
结果换了个语言,换了要翻译的内容,结果发现tk值就变了,旧tk值就无效了。
所以只能想办法搞清楚生成tk参数的逻辑,才能用代码去模拟。
要翻译内容:test translate logic
英文-》中文
此时tk值:389397.220291
那接着去分析,何处生成这个值的
很明显,只能搜出一个,也就是之前知道的url:
https://translate.google.cn/translate_a/single?client=webapp&sl=en&tl=zh-CN&hl=zh-CN&dt=at&dt=bd&dt=ex&dt=ld&dt=md&dt=qca&dt=rw&dt=rm&dt=ss&dt=t&pc=1&otf=1&ssel=0&tsel=0&kc=1&tk=389397.220291&q=test%20translate%20logic
即:
https://translate.google.cn/translate_a/single
没啥帮助,不知道具体哪里生成的。
看来要去找tk了。
结果搜出来东西太多。
搜 tk=
搜出来不是太多
去分别看看
https://apis.google.com/_/scs/abc-static/_/js/k=gapi.gapi.en.7kWSr24wXFc.O/m=gapi_iframes,googleapis_client,plusone/rt=j/sv=1/d=1/ed=1/rs=AHpOoo-i9r7IbCTUQfJ0v-FPhRKRS8aihQ/cb=gapi.loaded_0

var ok,nk,uk,vk,pk,sk,qk,wk,rk;_.tk=function(){if(nk){var a=new _.ke.Uint32Array(1);ok.getRandomValues(a);a=Number("0."+a[0])}else a=pk,a+=parseInt(qk.substr(0,20),16),qk=rk(qk),a/=sk+Math.pow(16,20);return a};ok=_.ke.crypto;nk=!1;uk=0;vk=0;pk=1;sk=0;qk="";wk=function(a){a=a||_.ke.event;var b=a.screenX+a.clientX<<16;b+=a.screenY+a.clientY;b*=(new Date).getTime()%1E6;pk=pk*b%sk;0<uk&&++vk==uk&&_.ye(_.ke,"mousemove",wk,"remove","de")};rk=function(a){var b=new _.Kh;b.IE(a);return b.Pg()};
-》有点可能,像function去计算出来的?
以及:
https://www.gstatic.cn/inputtools/js/ita/inputtools_1.js

a.metaKey;this.G=lk?a.metaKey:a.ctrlKey;this.B=a;a.defaultPrevented&&this.preventDefault()}},pk=function(a){return(nk?0==a.B.button:a.type==n?!0:!!(a.B.button&ok[0]))&&!(N&&lk&&a.ctrlKey)},rk=function(a,b,c,d,e){this.listener=a;this.A=null;this.src=b;this.type=c;this.capture=!!d;this.ma=e;this.key=++qk;this.hd=this.wd=!1},sk=function(a){a.hd=!0;a.listener=null;a.A=null;a.src=null;a.ma=null},tk=function(a){this.src=a;this.A={};this.B=0},vk=function(a,b,c,d,e,g){var h=b.toString();b=a.A[h];b||(b=a.A[h]=
不是太像:只是赋值
https://www.gstatic.com/og/_/js/k=og.qtm.en_US.D7UMNFi9kB0.O/rt=j/m=q_d,qmd,qcwid,qmutsd,qapid/exm=qaaw,qabr,qadd,qaid,qalo,qebr,qein,qhaw,qhbr,qhch,qhga,qhid,qhin,qhlo,qhmn,qhpc,qhpr,qhsf,qhtb,qhtt/d=1/ed=1/rs=AA2YrTt_kg-hfAJB9XubfvSn4sJw-qSM8A

var sk,uk,wk,xk,zk,Ak,Ck,Dk,Ik;sk=function(a){if(_.Aa(a)){for(var c=Array(a.length),d=0;d<a.length;d++){var e=a[d];null!=e&&(c[d]="object"==typeof e?sk(e):e)}return c}if(_.sc&&a instanceof Uint8Array)return new Uint8Array(a);c={};for(d in a)e=a[d],null!=e&&(c[d]="object"==typeof e?sk(e):e);return c};_.tk=function(a){return new a.constructor(sk(a.tb()))};uk=function(a,c){a.f=c;a.Hb&&a.qc?(a.stop(),a.start()):a.Hb&&a.stop()};
也有点像:
_.tk=function(a){return new a.constructor(sk(a.tb()))};
-》调用别的函数

非常像:
文件名translate_m_zh-CN.js
感觉或许是:对于(从英文?)翻译为中文,所以后缀是zh-CN.js ?
