Arduino POST未能完成

我正在使用以太网shield在Arduino设备上发出发布请求。该服务器是一个Node.js服务器，并且我已经处理了发布请求服务器端，同样的结果都是福尔马林和强大的。 POST被处理，但它不能完成文件传输。Arduino POST未能完成

loadstart：{ “时间”：1339574854222} “与BytesReceived”：178， “filesCompleted”：0

这是发送后的代码：

String boundary = "--73249889599006000"; 
String URL = "/upload"; 
String contentType = "text/plain"; 
String fileName = "text.txt"; 

void sendData(){ 
    String thisFile = "This is not the contents of thisFile"; 
    Serial.println("connecting..."); 
    // If you get a connection, report back via serial: 
    if (client.connect(server, 80)) { 
     Serial.println("connected"); 

     // Make a HTTP request: 
     String postHeader = "POST " + URL + " HTTP/1.1\n"; 
     postHeader += "Content-Type: multipart/form-data; boundary="; 
     postHeader += boundary + "\n"; 
     postHeader += "Host: 192.168.3.78\n"; 
     postHeader += "User-Agent: Arduino\n"; 
     postHeader += "Referer: http://192.168.3.78/upload\n"; 

     String requestHead = "\n--" + boundary + "\n"; 
     requestHead += "Content-Disposition: form-data; name=\"upload\"; filename=\"" + fileName + "\"\n"; 
     requestHead += "Content-Type: " + contentType + "\n\n"; 

     String tail = "\n--" + boundary + "--\n\n"; 

     int contentLength = requestHead.length() + thisFile.length() + tail.length(); 

     postHeader += "Content-Length: " + String(contentLength, DEC) + "\n\n"; 

     char charBuf0[postHeader.length() + 1]; 
     postHeader.toCharArray(charBuf0, postHeader.length() + 1); 
     client.write(charBuf0); 

     char charBuf1[requestHead.length() + 1]; 
     postHeader.toCharArray(charBuf1, requestHead.length() + 1); 
     client.write(charBuf1); 

     char charBuf2[thisFile.length() + 1]; 
     postHeader.toCharArray(charBuf2, thisFile.length() + 1); 
     client.write(charBuf2); 

     char charBuf3[tail.length() + 1]; 
     postHeader.toCharArray(charBuf3, tail.length() + 1); 
     client.write(charBuf3); 
    }

我会尝试从计算机发送确切的有效负载，看看这是Arduino的问题还是您正在创建的有效负载的问题。 – Pawel

当然：[POST分析工具]（http://stackoverflow.com/questions/1087185/http-testing-tool-easily-send-post-get-put）我发现telnet是最好的，因为你得到的反馈线按行。从arduino粘贴串行输出到telnet lbl，冲洗，重复。 – J0hnG4lt

线结束和其他一些调整排序它。这是更新的代码，适用于福尔马林。

String boundary = "--73249889599006000"; 
String URL = "/upload"; 
String contentType = "text/plain"; 
String fileName = "text.txt"; 

void sendData(){ 
    String thisFile = "This is not the contents of thisFile\r\n\r\n"; 

    Serial.println("connecting..."); 
    // if you get a connection, report back via serial: 
    if (client.connect(server, 80)) { 
    Serial.println("connected"); 

    // Make a HTTP request: 
    String postHeader = "POST " + url + " HTTP/1.1\r\n"; 
    postHeader += "Content-Type: multipart/form-data; boundary="; 
    postHeader += boundary + "\r\n"; 
    postHeader += "Host: 192.168.3.18\r\n"; 
    postHeader += "User-Agent: Arduino\r\n"; 
    postHeader += "Referer: http://192.168.3.18/upload\r\n"; 

    String requestHead = "--" + boundary + "\r\n"; 
    requestHead += "Content-Disposition: form-data; name=\"upload\"; filename=\"" + fileName + "\"\r\n"; 
    requestHead += "Content-Type: " + contentType + "\r\n\r\n"; 

    String tail = "--" + boundary + "--\r\n\r\n"; 

    int contentLength = requestHead.length() + thisFile.length() + tail.length(); 

    postHeader += "Content-Length: " + String(contentLength, DEC) + "\n\n"; 
    Serial.print("Content-Length: "); 
    Serial.println(String(contentLength, DEC)); 

    char charBuf0[postHeader.length() + 1]; 
    postHeader.toCharArray(charBuf0, postHeader.length() + 1); 
    client.write(charBuf0); 
    Serial.print(charBuf0); 

    char charBuf1[requestHead.length() + 1]; 
    requestHead.toCharArray(charBuf1, requestHead.length() + 1); 
    client.write(charBuf1); 

    char charBuf2[thisFile.length() + 1]; 
    thisFile.toCharArray(charBuf2, thisFile.length() + 1); 
    client.write(charBuf2); 
    Serial.print(charBuf2); 

    char charBuf3[tail.length() + 1]; 
    tail.toCharArray(charBuf3, tail.length() + 1); 
    client.write(charBuf3); 
    Serial.print(charBuf3); 
    } 
    else { 
    // kf you didn't get a connection to the server: 
    Serial.println("connection failed"); 
    } 
}
