Question

我需要对发布请求进行翻新，但是我有一个我不太了解的问题。在尝试代码之前，我使用 Postman 测试了api调用，并请求如下所示：

这是我的android代码：

public class API {

private static <T> T builder(Class<T> endpoint) {

    return new Retrofit.Builder()
            .baseUrl(Utils.API_BASE_URL)
            .addConverterFactory(ScalarsConverterFactory.create())
            .addConverterFactory(GsonConverterFactory.create())
            .build()
            .create(endpoint);
}
public static AllRequests request() {
    return builder(AllRequests.class);
}
}

编辑请求：

@POST("api/android-feedback")
@Headers({"Content-Type: application/x-www-form-urlencoded", "Authorization: F#@3FA@#Rad!@%!2s"})
Call<String> sendFeedback(@Body FeedbackBody body);

FeedbackBody：

public class FeedbackBody{
private final String email;
private final String feedback;

public FeedbackBody(String email, String feedback){
    this.email = email;
    this.feedback = feedback;
}

}

最后我构造了请求并等待响应，问题是我在onFail方法中收到消息

   private void sendFeedbackRequest(){
    API.request().sendFeedback(new FeedbackBody("testmeil@meil.com", "test feedback").enqueue(new Callback<String>() {
        @Override
        public void onResponse(Call<String> call, Response<String> response) {
            goToMainActivity();
        }

        @Override
        public void onFailure(Call<String> call, Throwable t) {
            Toast.makeText(SplashScreenActivity.this, R.string.try_again_later, Toast.LENGTH_SHORT).show();
        }
    });

编辑： 仍然无法正常工作..我认为我想出了问题所在，因为服务器端等待简单的POST请求而没有Json格式，我认为Retrofit默认使用JSON格式，如果我发送POST请求并使用JSON格式化Body参数服务器将无法解析我的请求，是否有可能像在POSTMAN一样发送简单的POST请求而无需使用JSON格式化？

要发送的Php api等待请求：

$ _ POST ['feedback'] ='blabla'; $ _POST ['email'] ='blabla ..';

如果他收到Json格式的请求就无法解析它，因此我收到失败响应。

Answer 1

您正在使用Gson转换器工厂。创建代表您身体的单个对象，而不是使用所有单个参数，可能会更容易。这样，您应该能够简单地遵循Retrofit网站上的示例。enter link description here 还有许多站点可以让您为自己生成普通的旧Java对象，例如this one：

例如您的Api通话：

 #include "functs.h"



MODULE_LICENSE("GPL");

#define DRIVER_AUTHOR "projecter"
#define DRIVER_DESC "Some echo driver"
MODULE_AUTHOR(DRIVER_AUTHOR);
MODULE_DESCRIPTION(DRIVER_DESC);

int Major;
static int Device_Open = 0;
static char msg[BUF_LEN];
static char *msg_Ptr;


static struct file_operations fops = {
    .read    = device_read,
    .write   = device_write,
    .open    = device_open,
    .release = device_release
};



//init _module functions

int init_module(void){

Major = register_chrdev(0, DEVICE_NAME, &fops);

if (Major < 0){
    printk(KERN_ALERT "I have failed to load!\n");
    return Major;
}

printk (KERN_ALERT "I was assigned major number %d\n" , Major);
printk (KERN_ALERT "Please create device with name  \n mknod /dev/%s c %d 0 \n" ,DEVICE_NAME , Major );
return 0;


}


int device_open(struct inode * inode, struct file *file){

static int counter = 0;
if (Device_Open){
    return -EBUSY;

}
Device_Open++;

sprintf(msg, "Good morning Dave, I was opened %d times", counter++);
msg_Ptr = msg;
try_module_get(THIS_MODULE);
return 0;
}



int device_release(struct inode  * inode, struct file *file){
    Device_Open--;

    module_put(THIS_MODULE);
    return 0;
}


ssize_t device_read(struct file  * file,  char * buffer, size_t length, loff_t *offset){
    int bytes_read = 0;
    if(*msg_Ptr == 0){
        return 0;
    }

    while(length && *msg_Ptr){
        put_user(* (msg_Ptr++), buffer++ );
        length--;
        bytes_read++;
}
        return bytes_read;



}

char temp_str[20] = {};
ssize_t device_write(struct file * file , const char * buffer, size_t length, loff_t *offset){
    static int MAX = 20;



    if (buffer){
        if(copy_from_user(temp_str, buffer , MAX) !=0 ){
            return -EFAULT;
        }
    else{
        printk(KERN_ALERT "DATA: %s \n\n", temp_str);



      }
   }



    printk(KERN_ALERT "I am Sorry Dave, But I cannot Let you do that !\n");
    memset(temp_str, 0, 20);
    return 1 ; 
  // return -EINVAL;
}

还有您的FeedbackBody类：

@POST("api/android-feedback")
Call<String> sendFeedback(@Body FeedbackBody feedback);

Answer 2

首先，您需要创建请求（POJO类）

public class FeedbackRequest {
   public String email;
   public String feedback;
}

当您致电sendFeedbackRequest()时，像下面这样传递FeedbackRequest”

FeedbackRequest req = new FeedbackRequest();
req.email= "email";
req.feedback= "feedback"
sendFeedbackRequest(req)

之后，您的sendFeedbackRequest()应该像这样

  private void sendFeedbackRequest(FeedbackRequest request){
      API.request().sendFeedback(request).enqueue(new Callback<String>() {
      @Override
      public void onResponse(Call<String> call, Response<String> response) {
        goToMainActivity();
      }

      @Override
      public void onFailure(Call<String> call, Throwable t) {
        Toast.makeText(SplashScreenActivity.this, R.string.try_again_later, Toast.LENGTH_SHORT).show();
    }
});

您的改装要求应该是这样的

@FormUrlEncoded
@POST("api/android-feedback")
@Headers({"Content-Type: application/json", "Authorization: F31daaw313415"})
Call<String> sendFeedback(@Body FeedbackRequest request);

现在它应该可以工作了。随便问什么。

Answer 3

Java：

@POST("/api/android-feedback")
Call<String> sendFeedback(@Body FeedbackBody feedback);

科特琳：

@POST("/api/android-feedback")
fun sendFeedback(@Body feedback: FeedbackBody): Call<String>

此外，可能您忘记了端点中的斜杠。
