Fiddler工作图解

Before explaining caught,先看一下我们的HTTPRequest header contains the parameters,这些参数的含义是什么.

HTTPRegular request header

抓包

Grasp package is the client sendserver的网络包,以及serverReturned to the client's package.

HTTPCaught the sample and parameters on

示例：

1. get请求：在百度中搜索 fiddler的使用,查看返回结果.
2. post请求：A website login

请求

在百度中搜索 fiddler的使用,抓取到的数据：Request header and line as shown below：

1、请求行

如图所示,This part is request line.

数据copyThe content is：

GET /s?ie=utf-8&f=3&rsv_bp=1&rsv_idx=1&tn=monline_3_dg&wd=fiddler%E4%BD%BF%E7%94%A8&fenlei=256&rsv_pq=d410c48d002f6544&rsv_t=16c9GIjIWx7au4zPRdR1ReDb8luE9OKPs8zeEqmb%2Bh7lQvG%2B4SonxX5O2LsV&rqlang=en&rsv_dl=ih_0&rsv_enter=1&rsv_sug3=2&rsv_sug1=2&rsv_sug7=001&rsv_sug2=1&rsv_btype=t&rsp=0&rsv_sug9=es_2_1&rsv_sug4=2835&rsv_sug=9 HTTP/1.1

These data meaning, in turn, is：请求方法、请求路径(包含了请求参数)、请求协议.
Request parameters can also see here,Comparison of the be clear at a glance.

2、请求头

As shown in the figure below is the content of the request header,Due to the content of the request header is too much,就不方便copy出来看了.

3、请求体

get请求没有请求体.
使用查询ip地址的postRequest to show the content of the request body.

响应

在百度中搜索 fiddler的使用,抓取server返回给客户端的响应消息.

1、状态行

如图所示,This part is the status line marked,The meaning of these parameters, in turn, is：响应协议、响应状态码、State response message.

2、响应头

Tell the browser what is server returned data.

3、响应体

如图所示,We see is the response body

3.1、查看响应结果

Depending on the value returned by the,It is ok to choose a different data format.

• 文本：TextView
• 图片：ImageView
• 网页：WebView
• json：Json
• xml：XML

3.2、中文乱码

If the response results contained in Chinese,Will display stil,不要慌,Click on the yellow block,The result of the response decoding can be.

正常显示了：

get和post区别

1. get没有请求体,post有请求体
2. get的请求参数拼接在url之后,用？分割URL和传输数据,Request parameters with&相连,而postSubmit data inhttp请求的请求体中.
   例如：加粗的是url,Is behind the request parameters and values

ie=utf8&f=3&rsv_bp=1&rsv_idx=1&tn=monline_3_dg&wd=fiddler%E4%BD%BF%E7%94%A8&fenlei=256&rsv_pq=d410c48d002f6544&rsv_t=16c9GIjIWx7au4zPRdR1ReDb8luE9OKPs8zeEqmb%2Bh7lQvG%2B4SonxX5O2LsV&rqlang=en&rsv_dl=ih_0&rsv_enter=1&rsv_sug3=2&rsv_sug1=2&rsv_sug7=001&rsv_sug2=1&rsv_btype=t&rsp=0&rsv_sug9=es_2_1&rsv_sug4=2835&rsv_sug=9

3. getRequest parameters of co,因为浏览器的urlInput box has length show.而postThe request parameter of any number
4. get请求没有post请求安全,因为get的请求参数在url中可见,而且getTo obtain the response data fromcache(缓存)中获取的.
5. getValue of the variable access request method isRequest.querystring.postTo obtain the value of a variable method isRequest.body

HTTPS抓包

在抓取httpsUnder the agreement of packets before,我们要先在fiddler中配置HTTPs,Consult my blog：fiddler工具详解-包含配置https
https的抓包和httpCaught the same,The above example some is fromhttps类型的网站.

快速抓包tips

1. 点击capturing开启抓包,Access to the data they want and then shut downcapturing,不要让fiddler继续抓包
2. 隐藏图片请求、Hidden link request.设置：菜单栏 - Rules - 勾选 hide image request和hide CONNECTs.
3. 关键字搜索,使用ctrl + f,在sessionList to find the key,To quickly locate you want that a request.然后选中这个session,右键- Mark - Red,可以标记一下.
4. 控制capturingThe beginning of the time,When we entered the final page started to capture,And then refresh this page,So you can directly get the list of session we want.
5. In the auxiliary tool bar - FiltersCan be set in the capture data from a web site.设置方法参考：fiddler工具详解 - 包含Filters的使用,在这篇文章的最后一部分.

In the interface testing purpose

如果devPeople didn't give interface document,So we can get interface by caught the way of information：请求url,请求方法、参数、响应结果.
还是以搜索 fiddler使用 为例展示.
The request of the interface path can be found here.辅助工具栏 - inspector - Raw,Request method is also can seeget请求,

打开postman,创建一个请求,输入请求URL,然后点击send,You can see our request the results.
