Question

我从我的arduino设备发送邮件请求到我的托管服务器它给我400错误请求错误。相同的代码在我的localhost中运行良好，但不在托管服务器上运行。我的arduino代码如果在下面给出。

    void callApi(String ID,String path,int comm,String message,int isResponseNeeded) {    
                  String serverPath="www.xyz.com";
                  String data = "{" ;
                  data = data + "\"id\": \""+ID+"\"," ;
                  data = data + "\"version\": \""+VERSION+"\"," ;
                  data = data + "\"command\": \""+comm+"\"," ; 
                  data = data + "\"message\": \""+message+"\"" ;
                  data = data + "}" ;
                  Serial.print("Send data...on=>");
                  Serial.println(path);
                  if (wifiClient.connect(serverPath,80)) {
                    Serial.println(data);
                    wifiClient.println("POST /abc/xyz HTTP/1.1");  
                    wifiClient.println("Content-Type: application/json");
                    wifiClient.print("Host: ");
                    wifiClient.println(serverPath);
                    wifiClient.print("Content-Length: ");
                    wifiClient.println(data.length());
                    wifiClient.print("\n");
                    wifiClient.print(data);
                    wifiClient.print("\n");
                    Serial.println("Data sent...Reading response..");
                    if(isResponseNeeded>0){
                       unsigned long timeout = millis();
                       while (wifiClient.available() == 0) {
                         if (millis() - timeout > 10000) {
                          Serial.println(">>> Client Timeout !");
                          break;
                         }
                      }     
                    String response;
                      while(wifiClient.available()){
                        String line = wifiClient.readStringUntil('\n');
                        response=line;     
                        Serial.println(response);   
                      }
                      Serial.println(response.length()); 

                }

=============================================== ============ 还有一件我观察过的事情。它运行GET请求很好。只有在托管服务器上发出POST请求时才会出现问题。

Answer 1

我想API服务要求POST内容和正文为application / x-www-form-urlencoded编码。

application/x-www-form-urlencoded or multipart/form-data?
