如何在使用HTTParty POST發送文件時設置Content-Length和Content-Type標題？

Question

我設置標題是這樣的： file所在的test.txt

size = File.size(file) 

h = { 
    "Content-Type":  'text/plain' 
    "Content-Length":  size.to_s, 
    "Other-Header":  'some-header'  
} 

b = File.read(file) 

HTTParty.post('/some/api/url', {headers: h , body: b}) 

頭獲取設置這樣的請求：

<- "POST /some/api/url\r\n 
Content-Type: text/plain\r\n 
Content-Length: 16\r\n 
Other-Header: some-header\r\n 
Connection: close\r\n 
Host: somehost.com\r\n 
Content-Length: 16\r\n 
Content-Type: application/x-www-form-urlencoded\r\n\r\n" 

的Content-Length和Content-Type添加並且複製，除了Transfer-Encoding被設置爲分塊。

如何設置Content-Length，Content-Type和Transfer-Encoding並避免HTTParty自行設置它們？

希望它很清楚。

Thx爲您的時間！

試試這個

HTTParty.post(END_POINT_URL, 
:body => data.to_json, 
:headers => { 'Content-Type' => 'application/json', 
'Content-Length' => content_length, 'Other-Header' => other_header, })
