http請求頭 Content-Type 詳解（三）

摘要：用NodeJs request子產品模拟第一篇用html請求的http請求

一、Content-Type: application/x-www-form-urlencoded

代碼：

var request = require("request");
var url = "http://localhost/test/curl/service.php";
request.post({
    url:url,
    proxy:'http://localhost:8888'
}, function(err, response, body){
    console.log(response.headers);
    console.log(body);
}).form({
    "name" : "zhangtao",
    "address" : 
});
           

或者這樣寫：

request.post({
    url : url,
    proxy:'http://localhost:8888',
    form : {"name" : "zhangtao","address" : }
}, function(err, response, body){
    console.log(body);
});
           

http請求：

POST http://localhost/test/curl/service.php HTTP/1.1
host: localhost
content-type: application/x-www-form-urlencoded
content-length: 54
Connection: close

name=zhangtao&address=&encode=%E4%B8%AD%E6%96%87%26
           

注意請求體内容做了url_encode

二、content-type: multipart/form-data;

代碼：

var request = require("request");
var url = "http://localhost/test/curl/service.php";
var formData = {
    "name" : "lu",
    "node_buffer" : new Buffer([, , ])
};
request.post({
    url : url,
    proxy : 'http://localhost:8888',
    formData : formData
}, (err, response, body) => {
    console.log(body);
});
           

http請求：

POST http://localhost/test/curl/service.php HTTP/1.1
host: localhost
content-type: multipart/form-data; boundary=--------------------------159485793623903092889117
content-length: 314
Connection: close

----------------------------159485793623903092889117
Content-Disposition: form-data; name="name"

lu
----------------------------159485793623903092889117
Content-Disposition: form-data; name="node_buffer"
Content-Type: application/octet-stream


----------------------------159485793623903092889117--
（注意上面node_buffer裡面的值是二進制的，這裡複制到這裡不顯示了）
           

post檔案，代碼：

var request = require("request");
var fs = require("fs");
var url = "http://localhost/test/curl/service.php";
var formData = {
    "name" : "lu",
    "node_buffer" : new Buffer([, , ]),
    "node_file" : fs.createReadStream(__dirname + '/share-qq.png')
};
request.post({
    url : url,
    proxy : 'http://localhost:8888',
    formData : formData
}, (err, response, body) => {
    console.log(body);
});
           

http請求：

POST http://localhost/test/curl/service.php HTTP/1.1
host: localhost
content-type: multipart/form-data; boundary=--------------------------521008285990597015283124
content-length: 1598
Connection: close

----------------------------521008285990597015283124
Content-Disposition: form-data; name="name"

lu

----------------------------521008285990597015283124
Content-Disposition: form-data; name="node_file"; filename="share-qq.png"
Content-Type: image/png

三、Content-Type: application/json;

代碼：

var request = require("request");
var url = "http://localhost/test/curl/service.php";
var sendJson  ={
    a : "a",
    b : "b"
}
request({
    url: url,
    method: "POST",
    proxy : 'http://localhost:8888',
    json: true,
    headers: {
        "content-type": "application/json"
    },
    body: sendJson
}, function(error, response, body) {
    console.log(body);
});
           

http請求：

POST http://localhost/test/curl/service.php HTTP/1.1
content-type: application/json
host: localhost
accept: application/json
content-length: 17
Connection: close

{"a":"a","b":"b"}
