我使用PHP Slim框架为Android应用程序构建REST API。
我在app中发布了body,它运行良好并向MySQL添加数据。但我的回答很麻烦。
我的回答JSON模型很简单;
{success:'yes'}
当我尝试在添加数据后获得响应时,Retrofit可以使用故障方法。但添加数据效果很好。我不知道我错过了哪里。这是我的代码;
PHP Slim框架文件
$response->withHeader('Content-Type', 'application/json');
$response->getBody()->write("{success:'yes'}");
return $response;
} catch (PDOException $e) {
echo '{"error": {"text": ' . $e->getMessage() . '}';
}
Android响应模型
public class Response_Success {
@SerializedName("success")
@Expose
String success;
public Response_Success(String success) {
this.success = success;
}
public String getSuccess() {
return success;
}
public void setSuccess(String success) {
this.success = success;
}
接口类
public interface API_Service {
@Headers("content-type: application/json")
@POST("api/user/add")
Call<Response_Success> addFacebookUser(@Body UserFacebook userFacebook);}
MainActivity中的API调用
API_Service service = Client.getRetrofitInstance().create(API_Service.class);
Call<Response_Success> userFacebookCall = service.addFacebookUser(userNew);
userFacebookCall.enqueue(new Callback<Response_Success>() {
@Override
public void onResponse(Call<Response_Success> call, Response<Response_Success> response) {
Toast.makeText(MainActivity.this, ""+response.body().getSuccess(), Toast.LENGTH_SHORT).show();
}
@Override
public void onFailure(Call<Response_Success> call, Throwable t) {
Toast.makeText(MainActivity.this, "was wrong", Toast.LENGTH_SHORT).show();
}
});
android studio中的调试模式;我得到了MaltFormedJsonException,但我在try catch中添加了该异常。
答案 0 :(得分:0)
您的Json回复
{成功: '是'}
无效。键和(字符串)值必须是双引号。
要么确保您的回复是双引号:
{ “成功”: “是”}
或者试试这个:
public class Bug
{
private int position;
private String direction;
public void initialPosition(int position ) {
position=0;
}
public void initialDirection(String direction) {
direction="right";
}
public void setPosition (int position) {
this.position = position;
}
public int getPosition() {
return position;
}
public void setDirection (String direction) {
this.direction = direction;
}
public String getDirection() {
return direction;
}
public void move() {
position+=1;
}
public void reverseDirection() {
if (direction=="right") {
direction="left";
}
else {
direction="right";
}
}
public String toString() {
return "Position: " + position + " & Direction: " + direction;
}
}
