QUESTION
I have this code
$ curl "https://api.weixin.qq.com:443/sns/jscode2session?appid=a&secret=b&js_code=c&grant_type=authorization_code"
and it can get response from server like the following
{"errcode":40013,"errmsg":"invalid appid rid: 5f96703e-5e24e4f1-691a9221"}
However when I try to replace hostname into ip, I failed with the following message
$ host api.weixin.qq.com
api.weixin.qq.com has address 180.97.7.108
api.weixin.qq.com has address 101.226.212.27
$ curl "https://101.226.212.27:443/sns/jscode2session?appid=a&secret=b&js_code=c&grant_type=authorization_code"
curl: (60) SSL: no alternative certificate subject name matches target host name '101.226.212.27'
More details here: https://curl.haxx.se/docs/sslcerts.html
curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
I hanve to add -k to make this work
$ curl "https://101.226.212.27:443/sns/jscode2session?appid=a&secret=b&js_code=c&grant_type=authorization_code" -k
{"errcode":40013,"errmsg":"invalid appid rid: 5f967132-1ee77e4b-2f378192"}c
I want to know why this happen, and if there is any secure problems here? If there is any, how can I remove this -k flag?
ANSWER
Answered 2020-Oct-26 at 08:56Without -k (or the long version --insecure), curl makes sure that the host you connect to (specified in the URL) is also correctly mentioned in the certificate provided by the server when it connects to it, as part of the TLS handshake. The check is done to make sure that it speaks to the legitimate machine.
The server certificate contains a list of host names (or wildcards) that curl checks if they match the host name in the URL.
When you specify an IP address in the URL, curl can only use that to compare against the names in the certificate. A server can still list specific IP addresses (https://1.1.1.1 is for example known to) but is very rare and rather exceptional.
Instead of using the IP address in the command line, use --resolve to use the right host name and make sure curl connects to the exact IP address of your choice.
Using -k completely disables curl's certificate check and you may then be subject for a MITM attack without being able to detect that.
QUESTION
I would like to implement a web application for a company in China. I need to use WeChat mini-APP to make the sign-up/login straight-forward.
Please correct my assumptions if I am wrong:
- To implement the login of the website from
WeChat, I need to use theOAuth2protocol - I also need to create a
WeChat developer accountunder a real name (need ID card or business registration stuff) if I want to diffuse the application - I also need to register a
domain nametoWeChatso that they can allowOAuth2 authenticationto this domain name
Question: can I still use my localhost virtual machine to develop my server? (I didn't try but I assume WeChat will reject to create an OAuth2 token for localhost 127.0.0.1)
Or do I need to have a development domain name with a development server available from the Internet so that I can debug the OAuth2 authentication?
EDIT 1: I tried to send a HTTPS POST request https://127.0.0.1:8080 and I got an error linking to this URL https://developers.weixin.qq.com/miniprogram/dev/framework/ability/network.html
EDIT 2: I tried to send a HTTPS POST request https://192.168.1.148:8080 which correspond to my dev computer and I got the error VM17415:1 Cannot send network request to localhost. (My test phone and computer both connected to network 192.168.1.x trough WiFi)
ANSWER
Answered 2020-Sep-24 at 03:04The documentation is available in English on the official WebSite [1]. It is written: network APIs allow communication with LAN IP addresses. So basically, if the phone is connected to the same network as the virtual machine (i.e. WiFi), one should be able to send any kind of HTTP/HTTPS request properly.
Note that the development environment WeChat DevTools block this feature by default. In order to enable it, the user should open the Project Settings and check the box 'Does not verify valid domain names, web-view (business domain names), TLS versions and HTTPS certificates.'.

QUESTION
I am trying to follow the WeChat Official Account tutorial to build an app.
In the step of
1.4 Basic Configuration for Developers
- After the restart is successful (python main.py 80), click the Submit button. If the prompt "token verification failed" appears, check the code or network link. If the token is successfully verified, you will be redirected back to the Basic Configuration page. Click Start.
However, based on the tutorial, there is no submit button related code. I cannot find the submit button.
When I open the pages through WeChat Official Account in the app WeChat, it just shows "hello, this is handle view".
Any guide? Thanks
main.py
import web
from handle import Handle
urls = (
'/wx', 'Handle',
)
if __name__ == '__main__':
app = web.application(urls, globals())
app.run()
handle.py
import hashlib
import web
class Handle(object):
def GET(self):
try:
data = web.input()
if len(data) == 0:
return "hello, this is handle view"
signature = data.signature
timestamp = data.timestamp
nonce = data.nonce
echostr = data.echostr
token = "xxxx" #Enter the value in **Basic Configuration ** at Official Accounts Platform.
list = [token, timestamp, nonce]
list.sort()
sha1 = hashlib.sha1()
map(sha1.update, list)
hashcode = sha1.hexdigest()
print "handle/GET func: hashcode, signature: ", hashcode, signature
if hashcode == signature:
return echostr
else:
return ""

ANSWER
Answered 2020-Mar-17 at 07:21I figured out the submit button here in the tutorial is referring the submit button at
开发 -> 基本配置 -> 服务器配置 -> 修改配置 -> URL
After you fill the URL, that submit (提交) button.
(Unfortunately, the WeChat Official Accounts settings panel only has Mandarin language not like the developer doc. But hopefully my screenshot will help locate it.)
QUESTION
so, I am trying to add a random element to my site with Font Awesome icons that change on reload. I found a helpful post, here, but I can't find a way to make the code work. I am getting the console log, but no icon is displayed. I've tried assigning my an id and having the Jquery add a random class to that, but that doesn't seem to work. Any ideas?
ANSWER
Answered 2020-Mar-06 at 21:49Your error description is not very precise, but I assume that the problem is that you are not adding the class (string), but its index.
Try replacing
$("#ranI").addClass("fas fa-", randIcon);
with
$("#ranI").addClass("fa fa-" + iconArray[randIcon]);
QUESTION
For example, I want to take a screenshot of this, but I'm only getting the following screenshot with the embedded code. What should I do?
import time
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
def test_fullpage_screenshot():
chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--start-maximized')
driver = webdriver.Chrome(chrome_options=chrome_options)
driver.get("https://mp.weixin.qq.com/s/cg4qHhta8nLx93PDaW1dHQ")
time.sleep(2)
height = driver.execute_script("return document.body.scrollHeight")
driver.set_window_size(1000, height) #the trick
driver.save_screenshot("screenshot1.png")
driver.quit()
ANSWER
Answered 2020-Feb-02 at 21:44This website is using lazy loading for images. Usually, it works by checking which images are in the viewport. It does it once on page load, and then on scroll.
So part of the solution would be to do this after you set the viewport :
driver.execute_script("window.scrollTo(0, 100)")
But it won't work as-is, since there is no space to scroll (your viewport includes the whole page).
Hence, you could:
- Set the viewport height to
height - 100 - Scroll down by 100px to trigger the lazy load
- Scroll back to the top
- Set the viewport height to
height
height = driver.execute_script("return document.body.scrollHeight")
driver.set_window_size(1000, height - 100)
driver.execute_script("window.scrollTo(0, 100)")
driver.execute_script("window.scrollTo(0, 0)")
driver.set_window_size(1000, height)
time.sleep(2) # new images need time to load
driver.save_screenshot("screenshot1.png")

Answered 2017-Jun-23 at 02:53Is it because of I didn't go through the wechat verification thus unable to obtain the user basic information?
Yes. To integrate wechat login, your wechat official account must be verified service account (subscribe account is not supported, even it is verified). Please refer to official document for more information.
How to get the wechat verification?
To get the wechat official account verified, you can follow the steps in the customer support document.
QUESTION
I am developing an APP with wechat login feature. After getting approval from wechat it will call a custom activity of my NativeScript APP. I am getting response correctly but how can I move to another page instated of the home page after doing some verification. I am using NativeScript + Angular.
getJSON("https://api.weixin.qq.com/sns/oauth2/access_token?appid=ID&secret=SECRET&code=" + res.code + "&grant_type=authorization_code").then((res) => {
console.dir(res);
// ===> here I want navigation
}, err => {
console.dir(err);
})
I tried like this:
frame.topmost().navigate("src/app/login/login.component");
but getting error:
JS: Unhandled Promise rejection: Cannot set property '_moduleName' of undefined ; Zone: ; Task: Promise.then ; Value: TypeError: Cannot set property '_moduleName' of undefined TypeError: Cannot set property '_moduleName' of undefined
Please give me some suggestions. Thanks in advance :)
ANSWER
Answered 2019-May-12 at 19:04A similar problem cost me an entire Weekend, without knowing how the companion controller .js or .ts files look like I can only recommend you go to the basics / source:
https://docs.nativescript.org/core-concepts/navigation#frame
it helped me find the problem in my code.
If you wrote a custom Page that does not start from a template chances are you wrote the controller too and it's easy to overlook some line that is present in the samples - even thou it looks like you don't need it.
If you paste your controller JS we could understand your context.
For instance, here is piece of code you should definitely include to help you debug:
in your page-you-navigate-to.xml
...
in your page-you-navigate-to.ts
import { EventData } from "tns-core-modules/data/observable";
import { Page } from "tns-core-modules/ui/page";
export function onPageLoaded(args: EventData): void {
const page = args.object;
var context = page.navigationContext;
page.bindingContext = context;
console.log("Target page Loaded.");
}
Start your debugger, and step through see where you have null values and read up on those method calls and their parameters.

ANSWER
Answered 2019-Feb-27 at 23:38According to the Chinese docs it would seem that you can no longer send more than 1 article.
图文消息条数限制在1条以内，注意，如果图文数超过1，则将会返回错误码45008 (Google Translate: The number of text messages is limited to one. Note that if the number of pictures exceeds 1, the error code 45008 will be returned.)

Unfortunately it looks like the English documentation has not yet been updated to reflect this change.
Curious to know if anybody has found a workaround / new message type that could be used similarly instead?
QUESTION
I'm trying to do a function which work with WECHAT API, Here is my code:
I use the code below to get a connection Token
internal static string Token(string CorpID, string Secret)
{
CorpID = CorpID ?? "wwe1f80304633";
Secret = Secret ?? "Ev7_oVN7RqD9k4yUy5pzkfcZ_QhX9l0VjZnAQ";
string token;
using (var wc = new WebClient())
{
token = wc.DownloadString($"https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid={CorpID}&corpsecret={Secret}");
}
if (token.Contains("access_token"))
{
return token.Split(',')[2].Split(':')[1].Replace("\"", "");
}
return "";
}
It's successful to get a valid token from WECHAT Server,
And the code below is I want to POST a request to WECHAT API and ask WECHAT to Send Message to selected Department Person.
internal static string SendMsg(string sendtext)
{
string ACTOKEN = "" + PDC.MSGTOKEN + "";
string CONTENT = "" + PDC.CONTENT + "";
string PostUrl;
using (var wc2 = new WebClient())
{
PostUrl = wc2.UploadString($"https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token={0}{1}", ACTOKEN, CONTENT);
}
return "";
}
public static void SendMsg2()
{
PDC.CONTENT = "Test Message";
string MsgContent = "{\"toparty\": \"" + PDC.DEPTID + "\",\"msgtype\": \"text\",\"agentid\": \"" + PDC.AGENTID + "\",\"text\": {\"content\": \"" + PDC.CONTENT + "\"},\"safe\":0}";
SendMsg(MsgContent);
MessageBox.Show("" + MsgContent + "");
}
And I Added a button on my WinForm and trying to make it work
private void BtnSendMsg_Click(object sender, EventArgs e)
{
string token = MSG.Token(null, null);
if (!string.IsNullOrEmpty(token))
{
PDC.MSGTOKEN = token;
MessageBox.Show("" + PDC.MSGTOKEN + "");
}
else
{
MessageBox.Show(" Invalid Token ");
}
MSG.SendMsg2();
}
However seems it doesn't work, and if I'm not wrong the problem on this part
internal static string SendMsg(string sendtext)
{
string ACTOKEN = "" + PDC.MSGTOKEN + "";
string CONTENT = "" + PDC.CONTENT + "";
string PostUrl;
using (var wc2 = new WebClient())
{
PostUrl = wc2.UploadString($"https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token={0}{1}", ACTOKEN, CONTENT);
}
return "";
}
