以下代码对我有用

try {
    await axios
      .get(uri.ApiBaseUrl + "AccountReport/GetTrialBalancePdfReport", {
        responseType: "blob",
        params: {
          ...searchObject,
        },
      })
      .then((response) => {
        //Create a Blob from the PDF Stream
        const file = new Blob([response.data], { type: "application/pdf" });
        //Build a URL from the file
        const fileURL = URL.createObjectURL(file);
        //Open the URL on new Window
         const pdfWindow = window.open();
         pdfWindow.location.href = fileURL;            
      })
      .catch((error) => {
        console.log(error);
      });
  } catch (error) {
    return { error };
  }
