简介:response.Header里常见Content-Type一般有以下四种:
application/x-www-form-urlencoded
multipart/form-data
application/json
text/xml
详解:
1.application/x-www-form-urlencoded
application/x-www-form-urlencoded是最常见的Content-Type,form表单默认提交方式对应的content-type.
当action为get时候,浏览器用x-www-form-urlencoded的编码方式把form数据转换成一个字串(name1=value1&name2=value2...),然后把这个字串追加到url后面,用?分割,加载这个新的url.
当action为post,且表单中没有type=file类型的控件时,Content-Type也将采用此编码方式,form数据将以key:value键值对的方式传给server.
表单提交:
<form action="/test" method="post">
<input type="text" name="name" value="zhangsan">
<input type="text" name="age" value="12">
<input type="text" name="hobby" value="football">
</form>
后台:
import java.io.Serializable;
public class Student implements Serializable {
private String name;
private String hobby;
private int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getHobby() {
return hobby;
}
public void setHobby(String hobby) {
this.hobby = hobby;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
@RequestMapping(value = "/test", method = RequestMethod.POST)
public String test(Student student) {
System.out.println(student.getName());
return "/test1";
}
2.multipart/form-data
当post表单中有type=file控件时content-type会使用此编码方式.
表单提交:
<form action="/test" method="post" enctype="multipart/form-data">
<input type="text" name="name" value="zhangsan">
<input type="text" name="age" value="12">
<input type="text" name="hobby" value="football">
<input type="file" name="file1"
</form>
后台:
@RequestMapping(value = "/test", method = RequestMethod.POST)
public String test(Student student,@RequestParam(value = "file1", required = false) MultipartFile file1) {
System.out.println(student.getName());
return "/test1";
}
3.application/json
随着json规范的流行,以及前后端分离趋势所致,该编码方式被越来越多人接受.
前后端分离后,前端通常以json格式传递参数,因此该编码方式较适合RestfulApi接口.
前端传参:
$.ajax({
url: ‘/test‘,
type: ‘POST‘,
data: {
"name": "zhangsan",
"age": 12,
"hobby": "football"
},
dataType: "json",
success: function (date) {
}
})
后台:
@RequestMapping(value = "/test", method = RequestMethod.POST)
public String test(@RequestBody Student student) {
System.out.println(student.getName());
return "/test1";
}
4.text/xml
XML-RPC(XML Remote Procedure Call)。它是一种使用 HTTP 作为传输协议,XML 作为编码方式的远程调用规范。
soapUI等xml-rpc请求的参数格式.
提交参数:
<arg0>
<name>zhangsan</name>
<age>12</age>
<hobby>footbal</hobby>
</arg0>
