In ASP. NET Ajax,
SYS. Services. profileservice provides a client proxy class for the personalized configuration file service,
So the applicationProgramYou can access the properties of the personalized configuration file through JavaScript.
For some usage of profile, you can refer to my blog.
Just like the authentication service and role service,
Let's start with how to use profile,
To use profile, you must first register the database of the website, that is, the 11 data tables,
If you use profile to access profile attributes,
Of course, you must declare these attributes first. You can declare these attributes in Web. config,
Some of these knowledge points must be learned if you do not understand them. My blog post will explain this part in detail,
You can refer
The following section defines the profile in Web. config and adds multiple profile attributes,
How to enable this profileservice
The profileservice is enabled in Web. config.
Here we will explain two attributes: writeaccessproperties and readaccessproperties,
Writeaccessproperties indicates the writable profile attribute,
Readaccessproperties indicates the readable profile attribute,
The above two values are set to = "*", indicating that all defined profile attributes are readable and writable,
If you do not define this,
For example, I define a constellation that is readable and writable,
Gender is readable and non-writable, while phone numbers are non-readable,
The following describes the profileservice class,
First
SYS. Services. profileservice. Load (propertynames,
Loadcompletedcallback,
Loadfailedcallback, usercontext)
Propertynames is a string array as a parameter. It contains the profile attribute to be loaded,
If you do not provide the propertynames parameter or the parameter is null,
AllRead PermissionProfile attribute field,
I will not describe the other three parameters. If you do not understand these parameters,
Then you have to look back and learn from my previous blog posts,
After successfully loading the profile, you can directly use the field properties to access the loaded configuration file,
The following describes the properties field.
SYS. Services. profileservice. properties. fieldname
Fieldname indicates the name of your profile attribute field,
Such as address, address, phone number, etc,
This properties field contains the profile data loaded using the load method,
Note that if you define a group-type attribute group in the Profile section,
The elements in properties can also be represented. You can access its sub-attributes through the elements,
For exampleSYS. Services. profileservice. properties. Phone. Mobile phone
Next we will introduce a very important method.Sava
SYS. Services. profileservice. Sava (propertynames,
Savacompletedcallback,
Savafailedcallback, usercontext)
The propertynames is
The usage of propertynames during the above interpretation of the load method is the same,
I will not explain the other two parameters,
This Sava method is used to save the properties of the configuration file specified by propertynames.
In addition to the methods and attributes described above
Defaultfailedcallback, defaloadloadcompletedcallback,
But I will not introduce it here, because they are all the same. I mean, it's boring to say it's not,
If you do not know anything, refer to msdn.
Here is the demo.

ThisCodeNow, let's see the results.
If you directly run this page, since no user has logged on,
So it will automatically jump to the specified page of loginurl defined in Web. config
Log On With Xiaozhen
After successful logon, the system will automatically jump to the page written above,
Then, press the "read" button to asynchronously read the profile of Xiaozhen.
Then, enter the profile attribute value to be modified in the text box.
Then press "save ".
You can see that the changes just made have also taken effect.
Cut down the image in the database.
The demo above mainly completes the load and save methods of profileservice,
As well as the properties field and some settings for related web. config,
The defaultfailedcallback attributes are not used,
However, these attributes are very easy to use. If you have the opportunity in the future, you can use them in a unified manner !!!
