Google has a hard time understanding the content of the page. However, you can help us by providing Google with clear clues about what the page means by including structured data on the page. Structured data is a standardized format used to provide information about a page and to categorize the content of the page; for example, on the recipe page, what is the ingredient, cooking time and temperature, calories, and so on.
For an article, it has a title, author, release time, content, and possibly a cover image. These content can be displayed directly to search engines in a way that Google's crawlers can understand.
And when you decide to provide Google with more friendly data, Google will also provide a more friendly experience for your potential users. For example, a typical wordpress site like wordpress. When we test this Rest API endpoint, it return a bunch of unformatted json data, is it make you feel dizzy!
In this case, you can see one of the post is published atthe post title, the the post content and much more There are 2 major advantages: 1. Your data never transmitted in the Open Internet, so you know it's secure; 2.
It's much faster than doing all the work in the server side, because there is no Internet Delay.How To Format A JSON File in Notepad++

Such access is enabled through selective authorization, by the user.
The API provides a set of endpointseach with its own unique path. Authorization is via the Spotify Accounts service. In requests to the Web API and responses from it, you will frequently encounter the following parameters:. Rate limiting is applied as per application based on Client ID, and regardless of the number of users who use the application simultaneously.
To reduce the amount of requests, use endpoints that fetch multiple entities in one request. When this happens, check the Retry-After header, where you will see a number displayed. This is the number of seconds that you need to waitbefore you try your request again. Some endpoints support a way of paging the dataset, taking an offset and limit as query parameters:.
In this example, in a list of 50 total singles by the specified artist : From the twentieth offset single, retrieve the next 10 limit singles. Note: The offset numbering is zero-based. Omitting the offset parameter returns the first X elements. Check the documentation for the specific endpoint and verify the default limit value.
Requests that return an array of items are automatically paginated if the number of items vary. For example, tracks in a playlist. In such case, the results are returned within a paging object. Most API responses contain appropriate cache-control headers set to assist in client-side caching:. Note: To target changes to a particular historical playlist version and have those changes rolled through to the latest version, use playlist endpoints that also return a snapshot-id.
For further information, see Working With Playlists. Whenever the application makes requests related to authentication or authorization to Web API, such as retrieving an access token or refreshing an access token, the error response follows RFC on the OAuth 2.
Apart from the response code, unsuccessful responses return a JSON object containing the following information:. Here, for example is the error that occurs when trying to fetch information for a non-existent track:. All requests to Web API require authentication. This is achieved by sending a valid OAuth access token in the request header.
OK - The request has succeeded. The client can read the result of the request in the body and the headers of the response. Accepted - The request has been accepted for processing, but the processing has not been completed. Bad Request - The request could not be understood by the server due to malformed syntax. The message body will contain more information; see Response Schema.
Unauthorized - The request requires user authentication or, if the request included authorization credentials, authorization has been refused for those credentials.
Not Found - The requested resource could not be found. This error can be due to a temporary or permanent condition.This article will cover the following:. In a nutshell, it gives us a human-readable collection of data that we can access in a really logical manner.
This creates an object that we access using the variable jason. Inside the object, we can declare any number of properties using a "name": "value" pairing, separated by commas. To access the information stored in jasonwe can simply refer to the name of the property we need. For instance, to access information about me, we could use the following snippets:. A slightly more complicated example involves storing two people in one variable.
For instance, if I needed to include information about myself and my brother in one variable, I might use the following:. To access this information, we need to access the array index of the person we wish to access. For example, we would use the following snippet to access info stored in family :. NOTE: This is beneficial if it will be necessary to loop through stored information, as it lends itself to a for loop with an automatically incrementing value. Another way to store multiple people in our variable would be to nest objects.
To do this, we would create something similar to the following:. Accessing information in nested objects is a little easier to understand; to access information in the object, we would use the following snippet:. Because of the popularity and ease of social media, many sites rely on the content provided by sites such as Twitter, Flickr, and others. The ease of retrieving data will vary based on the site providing the data, but a simple example might look like this:.
This example would request the latest feed items in JSON format and output them to the browser. The request we need to send asks for the latest photos from the user in question, along with flags asking for a JSON-formatted response.
The request we need to send will look like this:. Our function will be called loadFlickr.It is easy for humans to read and write. It is easy for machines to parse and generate. These properties make JSON an ideal data-interchange language. These are universal data structures. Virtually all modern programming languages support them in one form or another. It makes sense that a data format that is interchangeable with programming languages also be based on these structures.
An array is an ordered collection of values.
An array begins with [ left bracket and ends with ] right bracket. Values are separated bycomma. A value can be a string in double quotes, or a numberor true or false or nullor an object or an array.
These structures can be nested. A string is a sequence of zero or more Unicode characters, wrapped in double quotes, using backslash escapes. A character is represented as a single character string. A string is very much like a C or Java string.
A number is very much like a C or Java number, except that the octal and hexadecimal formats are not used. Whitespace can be inserted between any pair of tokens. Excepting a few encoding details, that completely describes the language. Introducing JSON.
In various languages, this is realized as an objectrecord, struct, dictionary, hash table, keyed list, or associative array. An ordered list of values.
The co-founders agreed to build a system that used standard browser capabilities and provided an abstraction layer for Web developers to create stateful Web applications that had a persistent duplex connection to a Web server by holding two Hypertext Transfer Protocol HTTP connections open and recycling them before standard browser time-outs if no further data were exchanged.
In particular, the byte order mark must not be generated by a conforming implementation though it may be accepted when parsing JSON. JSON does not provide syntax for comments. For maximum portability, these characters should be backslash-escaped. Numbers in JSON are agnostic with regard to their representation within programming languages. While this allows for numbers of arbitrary precision to be serialized, it may lead to portability issues.
For example, since no differentiation is made between integer and floating-point values, some implementations may treat 42 The JSON standard make no requirements regarding implementation details such as overflowunderflowloss of precision, rounding, or signed zerosbut it does recommend to expect no more than IEEE binary64 precision for "good interoperability".
There is no inherent precision loss in serializing a machine-level binary representation of a floating-point number like binary64 into a human-readable decimal representation like numbers in JSONand back, since there exist published algorithms to do this exactly and optimally.
Comments were purposefully excluded from JSON. InDouglas Crockford described his design decision thus: "I removed comments from JSON because I saw people were using them to hold parsing directives, a practice which would have destroyed interoperability. While JSON provides a syntactic framework for data interchange, unambiguous data interchange also requires agreement between producer and consumer on the semantics of a specific use of the JSON syntax.
The growth of AJAX powered sites has ensured that sites are able to engage in data loading in a rapid and non-synchronous manner or within a background without any delay in the rendering of the pages. Transitioning contents of certain elements within the page layout without the use of refresh buttons translate into ease of use and greater convenience for site visitors.
So if you are a site developer or web administrator, JSON training will yield good results for you. Another big plus point of learning JSON training is that the ease and growing popularity of social media such as Instagram, Pinterest, Flickr, Twitter, and Facebook has added a new complication to developing and maintaining sites. This is because RSS feeds will only be loaded if they are requested from the same domain on which hosting has been carried out.
This cross-domain problem can easily be dealt with through a method referred to as JSON that comes equipped with a callback function for sending JSON data back to the domain. This is the unique functionality of JSON that opens up all the doors of certainty rather than just letting users access feeds through windows of opportunity.

JSON translates into the parsing of the data and its faster execution. While the syntax is small and lightweight, this also means a faster response time. Apart from this, schema support is another major plus with JSON training because it can support multiple browsers and OSs and coding with JSON courses are simple and easy so much so that developers provide different kinds of functionality using this massive tool.
JSON filename extension is. The basic functionality of JSON has to be developed through data interchange format. JSON is a lightweight easy to understand a language-independent data interchange format text notation system.
It can be used across multiple browsers. It can be used for reading multiple data types in a single document. This text notation system can be used across different types of programming languages such as Perl, Python, and Ruby.
