Overview
Next we will use a real-time update rate to view the program to illustrate the specific development process of the online widgets on the OPhone. Our instance is called exchange rate communication. We can view the exchange rate relationships between various mainstream currencies. Let's take a look at the overall effect.
Basic knowledge
To implement the Widget networking example, we need to know about Ajax and DOM in two aspects. Below we will briefly introduce the content we need to use

MS: in the past two to three years, what are the important improvements of browsers?
CM: the browser technology has been improved in many aspects: the huge increase in Javascript speed and capacity, and the enhanced compatibility between XHTML, CSS, and SVG. However, in the long run, WAI-ARIA technology plays an important role in the development of the Internet.
MS: Will browsers be innovative in the mobile field in the next few year

In our test of using business data, the serialization/deserialization performance of PROTOBUF is about three times times that of Json.NET, and the serialized volume is about One-second of JSON, which can improve the throughput performance of WEBAPI to a considerable degree.Disadvantages of ProtobufThe DTO layer must refer to Protobuf-net to add attributes, which in some way leads to code intrusion. Basically dtos belong to Poco, relying on third-party package of words always feel a bit
type is passed for the same reason, the time matching error is also caused by inconsistent milliseconds. The general solution is to use string transmission. However, this is because the remedies do not solve the problem from the root cause. Therefore, we should directly use protobuf for processing.
Disadvantages of protobuf
The DTO layer must reference protobuf-net to add features, which causes code intrusion to some extent. Basically, DTO belongs to POCO. If you rely on a third-party package,
