Arduino GSM Shield WebClient 302

我把arduino mega和Arduino GSM Shield与Fyve（vodafone） - Sim结合在一起。长期来说，我想添加一个GPS，通过GSM模块发送位置数据到data.sparkfun.com。为了让我的代码正常运行，我开始使用来自arduino的GsmWebClient示例。问题是，我经常得到“HTTP/1.1 302 Found - Error”。所以显然我会重定向。有这样的感觉，必须有一个非常简单的解决方案，但我无法弄清楚。基本上通读整个互联网。我真的不知道现在是否正在发生，感觉非常愚蠢。Arduino GSM Shield WebClient 302

如果我将APN更改为web.vodafone.de GSM和GPRS连接，但客户端没有。

这里谈到的代码，并从串行响应：

// libraries 
#include <GSM.h> 


// PIN Number 
#define PINNUMBER "****" 

// APN data 
#define GPRS_APN  "event.vodafone.de" // replace your GPRS APN 
#define GPRS_LOGIN  "" // replace with your GPRS login 
#define GPRS_PASSWORD "" // replace with your GPRS password 

// initialize the library instance 
GSMClient client; 
GPRS gprs; 
GSM gsmAccess; 

// URL, path & port (for example: arduino.cc) 
char server[] = "arduino.cc"; 
char path[] = "/asciilogo.txt"; 
int port = 80; // port 80 is the default for HTTP 

void setup() { 
    // initialize serial communications and wait for port to open: 
    Serial.begin(9600); 
    while (!Serial) { 
    ; // wait for serial port to connect. Needed for native USB port only 
    } 

    Serial.println("Starting Arduino web client."); 
    // connection state 
    boolean notConnected = true; 

    // After starting the modem with GSM.begin() 
    // attach the shield to the GPRS network with the APN, login and password 
    while (notConnected) { 
    Serial.println("connecting gsm"); 
    if (gsmAccess.begin(PINNUMBER) == GSM_READY) { 
      Serial.println("gsm connected"); 
      delay(1000); 
      Serial.println("connecting gprs"); 
      if (gprs.attachGPRS(GPRS_APN, GPRS_LOGIN, GPRS_PASSWORD) == GPRS_READY) { 
       Serial.println("gprs connected"); 
       notConnected = false; 
     } 
     else { 
      Serial.println("gprs Not connected"); 
      delay(1000); 
    } 
     } 
    else { 
     Serial.println("gsm Not connected"); 
     delay(1000); 
    } 
    } 

    Serial.println("connecting..."); 

    // if you get a connection, report back via serial: 
    if (client.connect(server, port)) { 
    Serial.println("connected"); 
    // Make a HTTP request: 
    client.println("GET /asciilogo.txt HTTP/1.1"); 
    client.print("Host: "); 
    client.println("www.arduino.cc"); 
    client.println("Connection: close"); 
    client.println(); 


    } 
} 

void loop() { 
    // if there are incoming bytes available 
    // from the server, read them and print them: 
    if (client.available()) { 
    char c = client.read(); 
    Serial.print(c); 
    } 

    // if the server's disconnected, stop the client: 
    if (!client.available() && !client.connected()) { 
    Serial.println(); 
    Serial.println("disconnecting."); 
    client.stop(); 

    // do nothing forevermore: 
    for (;;) 
     ; 
    } 
}

那么，你有它。我希望有人能帮助我，这东西让我疯狂。

我只是有感情，沃达丰检查HTTP数据包报头，如果有，他们认为可疑的东西，它们会重定向他们。也许你可以尝试添加信息到http-header，像用户代理？

// if you get a connection, report back via serial: 
    if (client.connect(server, port)) { 
      Serial.println("connected"); 
      // Make a HTTP request: 
      client.println("GET /asciilogo.txt HTTP/1.1"); 
      client.print("Host: "); 
      client.println("www.arduino.cc"); 
      client.println("User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; Trident/7.0; rv:11.0) like Gecko"); 
      client.println("Connection: close"); 
      client.println(); 
    }
