在放心 post 调用中获取不受支持的字符集 \"ISO-8859-1\ 错误

Question

我试图使用 Best Buy api playground 进行 post 调用，我编写了常用代码来进行 post 调用，但我收到了 500 错误字符集不受支持“ISO-8859-1。我正在使用数据提供程序 class 将 json 有效负载传递给 post 调用

这是 swagger API 文档

这里是控制台日志：-

这里是 post 调用的代码

public class TC002_BestBuy_CreateProduct extends TestBase{

    private static String prodID;

    public static String getVariable(){
        return prodID;
    }

    public static void setVariable(String var){
        prodID = var;
    }

    @BeforeClass
    public void createProductData(){
        logger.info("----Create new product request test started----");

        TestBase.initialization();
    }

    @AfterClass
    public void tearDown(){
        logger.info("----Create new product request test completed");
    }

    @Test(priority = 1,dataProvider = "apiDataProvider",dataProviderClass = APIDataProvider.class,description = "post call and status check for create product")
    public void createProduct(String name,String type,String price,String shipping,String upc,String description,String manufacturer,String model,String url,String image){

        TestBase.response= given()
                .baseUri(property.getProperty("BaseURI"))
                .queryParam("name",name)
                .queryParam("type",type)
                .queryParam("price",price)
                .queryParam("shipping",shipping)

                .queryParam("model",model)
                .queryParam("url",url)
                .queryParam("image",image)
                .post(property.getProperty("createProductURL"));


        logger.info("The response for create product");
        TestBase.response.prettyPrint();

        String productId=TestBase.response.jsonPath().get("id");
        setVariable(productId);

    }
  }

这是 excel 实用程序 class 读取 excel 数据的代码

public static int getRowCount(String xlfile,String xlsheet) throws IOException
    {
        fi=new FileInputStream(xlfile);
        wb=new XSSFWorkbook(fi);
        ws=wb.getSheet(xlsheet);
        int rowcount=ws.getLastRowNum();
        wb.close();
        fi.close();
        return rowcount;
    }


    public static int getCellCount(String xlfile,String xlsheet,int rownum) throws IOException
    {
        fi=new FileInputStream(xlfile);
        wb=new XSSFWorkbook(fi);
        ws=wb.getSheet(xlsheet);
        row=ws.getRow(rownum);
        int cellcount=row.getLastCellNum();
        wb.close();
        fi.close();
        return cellcount;
    }


    public static String getcellData(String sheetname, int rowNum, int colNum) {

        row = ws.getRow(rowNum);
        cell = row.getCell(colNum);
        int index = wb.getSheetIndex(sheetname);

        if (rowNum <= 0) {
            return "";
        } else if (index == -1) {
            return "";
        } else if (cell == null) {
            return "";
        } else if (row == null) {
            return "";
        } else if (cell.getCellTypeEnum() == CellType.STRING) {
            return cell.getStringCellValue();
        } else if (cell.getCellTypeEnum() == CellType.NUMERIC || cell.getCellTypeEnum() == CellType.FORMULA) {
            String cellValue = String.valueOf(cell.getNumericCellValue());
            if (HSSFDateUtil.isCellDateFormatted(cell)) {
                DateFormat df = new SimpleDateFormat("dd/mm/yy");
                Date date = cell.getDateCellValue();
                cellValue = df.format(date);
            }
            return cellValue;
        } else if (cell.getCellTypeEnum() == CellType.BLANK) {
            return "";
        } else return String.valueOf(cell.getBooleanCellValue());
    }


    public static void setCellData(String xlfile,String xlsheet,int rownum,int colnum,String data) throws IOException
    {
        fi=new FileInputStream(xlfile);
        wb=new XSSFWorkbook(fi);
        ws=wb.getSheet(xlsheet);
        row=ws.getRow(rownum);
        cell=row.createCell(colnum);
        cell.setCellValue(data);
        fo=new FileOutputStream(xlfile);
        wb.write(fo);
        wb.close();
        fi.close();
        fo.close();
    }
}

这里是数据提供者class，从excel

读取后提供数据

public class APIDataProvider {

    @DataProvider(name = "apiDataProvider")
    public Object[][] getEmpData() throws IOException {

        String path=System.getProperty("user.dir")+"/TestResources/TestData.xlsx";
        int row=ExcelUtils.getRowCount(path,"Sheet1");
        int col=ExcelUtils.getCellCount(path,"Sheet1",1);

        String empdata[][]=new String[row][col];

        for (int i = 1; i <= row; i++) {
            for (int j = 0; j < col; j++) {
                empdata[i - 1][j] = ExcelUtils.getcellData("Sheet1", i, j);
            }
        }
      return (empdata);
    }
}

Answer 1

我大摇大摆地看到请求是 POST，而不是 Get，因此您应该更改如何设置 API 调用：更改 queryParam --> post 正文。阅读更多：https://github.com/rest-assured/rest-assured/wiki/Usage#request-body。示例：

@Test
void demo() {
    BestBuyProduct aProduct = new BestBuyProduct();
    aProduct.setName("apple");
    aProduct.setType("fruit");
    aProduct.setPrice(30);
    aProduct.setShipping(30);
    aProduct.setUpc("DF400");
    aProduct.setDescription("test");
    aProduct.setManufacturer("XYZ");
    aProduct.setModel("AB123");
    aProduct.setUrl("http://example");
    aProduct.setImage("/apple.img");
    
   given().contentType(ContentType.JSON)
           .body(aProduct)
           .post("to_your_api_endpoint");
}

要从 POJO 转换 --> json，不要忘记将 jackson 或 gson 添加到类路径。

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.10.3</version>
    </dependency>

顺便说一句，不是直接使用 Apache POI，而是可以使用 https://github.com/ozlerhakan/poiji 转换 excel --> POJO。这将有助于减少读取 excel 文件的复杂性，并减少测试用例的参数数量。
