bw16 http post报错
Body returned follows:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd">
<HTML><HEAD><TITLE>Length Required</TITLE>
<META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD>
<BODY><h2>Length Required</h2>
<hr><p>HTTP Error 411. The request must be chunked or have a content length.</p>
</BODY></HTML>
代码如下：
char post_content[]="{\"id\":1,\"mc_id\": \"AGV02\"}；
int str_length = sizeof(post_content)/sizeof(post_content[0]);
Serial.println("str_length:");
Serial.println(str_length);
http_post.sendHeader("Content-Length",str_length);
err2 = http_post.post(ip_addr2,kHostname_post,30200,post_kPath2,post_content);
Serial.println("err2:");
Serial.println(err2);
发送头信息不对，请给个示范呢，如何发送长度信息？感谢 |
