This post is a continuation of post on https://bbs.csdn.net/topics/395825790,

This requirement is to query to the stroke order in https://bihua.51240.com/e9bb84__bihuachaxun/images download (below) to form PictureBox in c #,


Thoughts and questions:
1, press F12 in the Google browser, in the NetWork - & gt; The Filter - & gt; Search box input method: "GET", the results below, and on different is: on the input method: "Post" after only one result, and now there are 9 (pictured), then how can I know what is the result of the request to return the I need pictures?



In addition of Http and Https, I have some questions, consult the together:
Problem two: Https is safer than Http was not always hear? Major browsers such as Google will lock on HTTPS in front, but why the following url is an exception



Question 3: is not to say that the HTTPS during transmission encryption the content? Then how I chart with F12 interception parameters or plain code?


Problem is more, the rare encounter outbreaks have time to study well, please generous time under the guidance teacher, ha ha,

Those not picture, click the query button should be returned from the server after the HTML code, you can see on the web right is saved as a picture?

CodePudding user response:

1. Can in the debug window Elements TAB select the image you're interested in, then see & lt; Img> What is label of SRC, the img tags address is what you want,
If HTTPS but browser tip 2. There is no security, so is likely to be used by the server SSL certificate is not in conformity with the browser security specification, specific reasons may be expired, revoked certificate has been issued by institution, the certificate issuing authority is not trust, etc., this time you click "unsafe" those three words, the browser should display the specific reason, although the certificate is not in conformity with the requirements, but is still in the process of transmission encryption, just can't make sure the content of the website will be redirected or tampered with,
3. "HTTPS during transmission encryption" the content is right, but what you see is not the contents of the transmission process, but the browser to receive after the disclosure of the content, if the browser can solution, the content can not be used, HTTPS to guarantee is that some people even to monitor your network communication, which could be installed in the router Trojan horse), also cannot get or tamper with the data transmission between you and the server,

1. Can be in the debug window Elements TAB select the image you're interested in, then see & lt; Img> What is label of SRC, the img tags address is what you want,

Thank you,
2, 3 explain clearly,
1 answer a little carried away, I want to ask the browser parses the nine HTTP requests, but how do I determine "& lt; Img> The SRC "place of the label page which Get requests the Response?

1. The picture is almost impossible to POST request,
2. To find the SRC img tags of interest to you, is the address the request

CodePudding user response:

In Elements TAB can determine what you want is the part of a picture,
I just open the web page, and not,
