我如何從HTTP響應中獲取正文？

Question

嘿，我正在做的和Arduino的項目，我想從一個HTTP請求得到了身體，這裏是代碼：

// This will send the request to the server 
client.print(String("GET ") + url + " HTTP/1.1\r\n" + 
      "Host: " + host + "\r\n" + 
      "Connection: close\r\n\r\n"); 
delay(100); 
int liniea_info = 0; 
while(client.available()){ 
    String line = client.readStringUntil('\r'); 
    if(liniea_info == 13){Serial.print(line);} 
    Serial.print(liniea_info); 
    ++liniea_info; 
} 

這工作不錯，不整liniea_info返回我：

Requesting URL: /output/***.csv?colors=11 
HTTP/1.1 200 OK 
Access-Control-Allow-Origin: * 
Access-Control-Allow-Headers: X-Requested-With 
Content-Type: text/plain 
Transfer-Encoding: chunked 
Date: Sat, 17 Jun 2017 08:09:31 GMT 
Connection: close 
Set-Cookie: SERVERID=; Expires=Thu, 01-Jan-1970 00:00:01 GMT; path=/ 
Cache-control: private 

34 
colors,day,timestamp 
11,12,2017-06-17T07:48:10.619Z 

0 

我以爲用int liniea_info我只會得到我想要的那一行，即線條"11,12,2017-06-17T07:48:10.619Z"，但是不行，只打印第一行。

任何人都看到我在做什麼錯誤或如何做到這一點？

不要重新發明輪子。只需使用HTTPClient庫。這個庫處理請求和響應。

添加到包括：

#include <ESP8266HTTPClient.h> 

而乾脆：

HTTPClient http; 
http.begin("http://www.sample-videos.com/csv/Sample-Spreadsheet-10-rows.csv"); 
int statusCode = http.GET(); 
Serial.println(http.getString()); 
http.end();
