with the rapid development of "cashless society", more and more businesses begin to use various electronic payment platforms to collect money, which brings a lot of convenience to people
however, there are still troubles. One of them is that different electronic payment platforms must use different collection codes to collect money
can't this problem be solved? no, it isn't. Recently, the new code collection function of sesame two dimensional code has been fired up. It can easily merge the payment codes between Alipay and WeChat.
however, the security problems behind it can not be ignored
first of all, the combined QR code jump link has not been encrypted with HTTPS, which leads to a great increase in the possibility of tampering with the QR code or collection link
secondly, what we use here is a third-party platform service after all. The control of the server is not in our own hands, and it also involves money transactions, which inevitably makes people feel uneasy
in fact, you only need to understand the principle, and if you have your own server, you can build a server to provide QR code merging service, which is safe and convenient< First, let's understand the concept of user agent
user agent (hereinafter referred to as UA) can be understood as a browser telling the web server what browser (or software) it is currently using to access it. The following is an example of user agent:
Mozilla / 5.0 (Macintosh; Intel Mac OS X 10_ 12_ 6) Applewebkit / 603.3.8 (KHTML, like gecko) version / 10.1.2 Safari / 603.3.8
to put it simply, the combined QR code content is actually a common web link. When the client accesses the link, the web server determines the content returned to the client by identifying the UA field in the client request message. For example, after the user scanned the two-dimensional code with Alipay, Alipay used an embedded browser to access the link, and the web server recognized the receipt of Alipay's software and then returned to Alipay's collection link. The process is shown in the following figure:
through the access log of the web server (the process is brief), we can see that the UA of wechat contains the string micromessanger; Alipay's UA contains the AlipayClient string. < The link in the br />
Alipay payroll code uses the standard HTTPS protocol. https://QR.ALIPAY.COM/FKX09xxxxxxQWMZL3JT64C , support direct access to the link to jump to the payment interface
the link in wechat collection code uses wechat's own protocol (such as wxp://_ Ro07e) and not supported

The market value of Guizhou Maotai is close to 3 trillion yuan, and the banking stocks are strongly protecting the market. Affected by the pre Festival effect, the Shanghai composite index was still wandering around 3500 points yesterday (February 4), and there was no obvious signal of upward breakthrough
The downturn of theindex can not prevent Guizhou Maotai from reaching new heights. As of the close, Guizhou Maotai closed at 2320.85 yuan per share, up 5.98% in a single day. Since July 6 last year, Guizhou Maotai successfully hit the market value of 2 trillion yuan and the stock price broke through the 1600 yuan mark, its investment value has been recognized by the market continuously, and now it is only one step away from the market value of 3 trillion yuan
in addition to the frequent good news of Guizhou Maotai, "Yinmao" China Merchants Bank also broke new heights for two consecutive days. From the overall performance point of view, the bank's performance yesterday was also second only to food and beverage and comprehensive, becoming one of the only three instries with positive growth among the 28 Shenyi instry indexes. In the frequent fluctuations of the market, banks once again play the role of "protector" and "haven"
The fluctuation of
index indicates that the two camps holding shares and currencies before the festival have entered the final "war" stage. According to private paipai net's previous survey, 89% of private equity tend to hold shares
as a result, subscription free private placement network interviewed a number of private placement institutions, including potong investment, Rongzheng Chuangyuan, Honghan investment, Weno asset, Jianhong times
The short-term market changes rapidly because of the lack of specific answers and standing in line. On the whole, the current index is pushed to this position by the big market leader. The valuation of these big market companies is not low and fluctuates greatly. Recently, there have been some thunderbolts in the white horse stock market. Therefore, they are not very optimistic about the A-share index at this stage. They choose to long the Hang Seng Index with the core of financial sector and Internet leader, and short the CSI 300 index in a small amount According to Wang Xuhui, manager of Rongzheng Chuangyuan fund, the overall sentiment of the market is relatively cautious, and the two major variables of the market are liquidity and economy. At present, the market has certain expectations for the marginal tightening of liquidity, the prosperity of manufacturing instry is at a high level, and the marginal utility of economic boost is limited. However, the recurrence of the epidemic may have an impact on the recovery of exports and services. The risk preference before the festival is more likely to be sorted out, and it is more likely to rise after the festivalHonghan investment said in an interview with paipaipai.com: "we will adjust our positions before the festival and rece our holdings of the varieties that have increased too much. We don't think it's important to hold shares or currency itself. In terms of the outlook before and after the Spring Festival, there will be some adjustment pressure on the market. The liquidity factor is the main concern, and it is the appropriate choice to keep room in strategy. "
"you can hold shares for the holidays. At present, there is no big risk event ring the Spring Festival. Small trading volume before the Spring Festival will lead to greater market volatility. " Zhao Yuanyuan, fund manager of Jianhong times, believes that "the strength of currency after the festival depends on whether the epidemic is out of control, whether the RMB is greatly appreciated, and whether there is a credit default. This year's Spring Festival has a small number of inter provincial floating population. We believe that there will not be a new round of monetary stimulus e to the out of control epidemic
the graal normalization of European and American markets will rece the pressure on China's export and appreciation, and the central bank does not need to loosen the currency to restrain the appreciation speed. From the perspective of public opinion, the all-round tightening of real estate policy also reces the probability of loose currency. Therefore, I think there is no index market after the festival. The key is to choose stocks. It is suggested that investors choose professional investment institutions. "
liquidity is turning sharply? Dr007 index set a new high in 2015! 89% of private equity still hold shares

what is the role of leverage? It is to move a large object with a small force through a fulcrum, which requires a lever. Although the state has abolished leveraged trading, you can't say it doesn't exist. At present, this leverage mode is widely used in the foreign exchange trading platform provided by foreign regular foreign exchange dealers in China. It also provides us ordinary investors with a small and broad opportunity. In short, the threshold for foreign exchange investment is very low. As long as you have 500 US dollars, that is 3500 RMB. You can adjust your trading according to the ups and downs of the whole foreign exchange market. All funds are accumulated from less to more, which requires a healthy investment mentality and never give up the spirit of pursuing wealth
OK. Suppose you follow my advice and decide to invest 3500 yuan in foreign exchange. Let's analyze what problems you are facing and what worries you have. I'll answer for you one by one
What are the advantages of the first foreign exchange investment
Second, how to judge whether an investment company is formal
thirdly, how can you ensure that every penny you invest is safe and secure< How to open an investment account
fifthly, how to make profits from foreign exchange investment< First of all:
compare instrial and financial investment. Now it's hard to invest in instries. The country has excess capacity and its procts are unsalable. So many people adjust their direction to financial investment. Foreign exchange investment is a kind of financial investment. Financial investment has risks but high returns. It is Wenzhou People's belief that only when they dare to take risks can they get big gains. I also hope that successful Wenzhou people can become examples for us to learn from, and the belief and courage of Wenzhou people can also become the belief and courage of each of us. When investing in foreign exchange, you don't have to worry about whether the foreign exchange market will be affected by indivial, group or even country. The whole foreign exchange market is a global market. Any person or group who wants to interfere and manipulate the foreign exchange market is like an ant stirring the sea. No country with sound system will make fun of its own currency. Therefore, the rise and fall of the foreign exchange market is only affected by the global economy, not by a single indivial or event
when it comes to financial investment, we all know stocks, but stocks can only be bought up, not down. Foreign exchange is different. When you go up, you can buy at a low price and sell at a high price. When you go down, you can sell at a high price and buy at a low price to earn the difference between the two. This will greatly enrich our investment routines. The opening and closing time of the stock market is the time for everyone to go to and from work. Therefore, you may not have too much energy to pay attention to the stock market and seize the favorable profit opportunities. But foreign exchange is not the same, it is the global 24-hour uninterrupted market, domestic night comes, the United States and Europe just ring the day. Only on weekends, like the stock market, will the market be closed for two days. It's the 24-hour uninterrupted time that allows you to make the most wealth in your limited time< Second,
the formality of foreign exchange investment companies depends on whether the foreign exchange dealers behind them are formal. How to judge? Now a regular foreign exchange dealer must be supervised by the association of financial institutions, just as the domestic stock market is supervised by the China Securities Regulatory Commission, so as to protect the capital security and interests of every shareholder. So who is in charge of foreign exchange? As the foreign exchange market has not been fully opened by the domestic government, the domestic market is quite mature, which is mainly e to the credit of foreign dealers. At present, the foreign exchange market is mainly regulated by foreign authorities. NFA (National Futures Association), CFTC (Commodity Futures Trading Commission) and FSA (Financial Services Authority) are the main regulators in the United States. The United Kingdom is the most perfect country in the world with the most perfect financial services, and through the Financial Services Authority (FSA), it strictly supervises all the financial service institutions registered in its territory. When domestic banks set up subsidiaries and domestic and international banks in the UK this year, they also need to submit an application to the Financial Services Authority (FSA) and allow them to register and carry out business after approval. If the investment company you contact is a trading company, and one or more of the above three regulators supervise at the same time, Congratulations, your capital is safe, and the investment company you choose is no problem
