多部分formdata POST请求对我而言在Cypress中不起作用

没有任何东西适合我。如果我使用cy.request(),则无法使用它发送包含文本和图像的formdata。因此,我必须通过XHR路线。因此,在我的command.js中,我使用了以下代码来创建命令:-

Cypress.Commands.add("formrequest", (method, url, formData, done) => {
  cy.window().then(win => {
    return new Promise((resolve, reject) => {
      const xhr = new XMLHttpRequest();
      xhr.open(method, url, false);
      xhr.setRequestHeader("accept", "application/json");
      xhr.setRequestHeader("access-token", accesstoken);
      xhr.setRequestHeader("client", client);
      xhr.setRequestHeader("expiry", expiry);
      xhr.setRequestHeader("token-type", tokentype);
      xhr.setRequestHeader("uid", uid);
      xhr.setRequestHeader("Accept-Encoding", null);
      xhr.onload = function() {
        done(xhr);
      };
      xhr.onerror = function() {
        done(xhr);
      };
      xhr.send(formData);
    });
  });
});

现在,当我调用它时,我将首先构造一个BLOB,然后在我的formdata中使用它,以便稍后发送XHR请求。像这样:-

it.only("Test XHR", () => {
    cy.AppLogin();
    cy.fixture("/images/clients/Golden JPEG.jpeg", "binary").then(imageBin => {
      // File in binary format gets converted to blob so it can be sent as Form data
      Cypress.Blob.binaryStringToBlob(imageBin, "image/jpeg").then(blob => {
        // Build up the form
        const formData = new FormData();

        formData.set("client[name]", "Test TER"); //adding a plain input to the form

        formData.set(
          "client[client_logo_attributes][content]",
          blob
          //"Bull Client.jpg"
        ); //adding a file to the form

        // Perform the request
        cy.formrequest(method, url, formData, function(response) {
          expect(response.status).to.eq(201);
        });
      });
    });
  });

请注意,cy.AppLogin()设置请求标头,如accesstoken,client,expiry,tokentype和uid。

请参考附件文件(XHRfromCypress.txt),以检查使用上面提供的代码生成的XHR请求。另外还附有一个文件(XHRfromCypressUI.txt),用于显示从应用程序UI运行cypress end-2-end测试时发出的XHR请求。

我不断收到405,方法不允许错误。

API测试

端到端测试有效,但是使用上述代码的API测试根本行不通。我也尝试了cy.request(),但是由于它没有显示在“开发人员”选项卡中,因此我不确定是否正确完成了操作。另外,我对在那里使用formdata的方式表示怀疑。表示cy.request()是否甚至可以接受dormdata。

我已经导出了(E2E和API)XHR,以防万一。

我需要添加任何库来发出XHR请求吗?我只是在项目设置中添加了赛普拉斯库。

将所有代码移入测试用例都无法解决任何问题

it.only("POSTing", () => {
    cy.fixture("/images/clients/Golden JPEG.jpeg", "binary").then(imageBin => {
      Cypress.Blob.binaryStringToBlob(imageBin, "image/jpeg").then(blob => {
        data.set("client[name]", "Test TER fails");
        data.set("client[client_logo_attributes][content]", blob);
        xhr.open(method, url);
        xhr.setRequestHeader("accept", "application/json");
        xhr.setRequestHeader("access-token", accesstoken);
        xhr.setRequestHeader("client", client);
        xhr.setRequestHeader("expiry", expiry);
        xhr.setRequestHeader("token-type", tokentype);
        xhr.setRequestHeader("uid", uid);
        xhr.send(data);
      });
    });
  });

感谢Eric。它遵循github.com/javieraviles/cypress-upload-file-post-form

中提到的Eric的建议和说明对我有用。
Cypress.Commands.add(
  "Post_Clients",
  (imagePath, imageType, attr1, attr2, attr1Val, done) => {
    cy.fixture(imagePath, "binary").then(imageBin => {
      Cypress.Blob.binaryStringToBlob(imageBin, imageType).then(blob => {
        const xhr = new XMLHttpRequest();
        xhr.withCredentials = true;
        const data = new FormData();
        data.set(attr1, attr1Val);
        data.set(attr2, blob);
        xhr.open("POST", "https://api.teamapp.myhelpling.com/admin/clients");
        xhr.setRequestHeader("accept", "application/json");
        xhr.setRequestHeader("access-token", accesstoken);
        xhr.setRequestHeader("client", client);
        xhr.setRequestHeader("expiry", expiry);
        xhr.setRequestHeader("token-type", tokentype);
        xhr.setRequestHeader("uid", uid);
        xhr.onload = function() {
          done(xhr);
        };
        xhr.onerror = function() {
          done(xhr);
        };
        xhr.send(data);
      });
    });
  }
);


it.only("API POSTing TEST", () => {
    cy.Post_Clients(
      "/images/clients/Golden JPEG.jpeg",
      "image/jpeg",
      "client[name]",
      "client[client_logo_attributes][content]",
      "Test Attr 1 Value is Hi!!!",
      response => {
        cy.writeFile(
          "cypress/fixtures/POST API OUTPUT DATA/Client.json",
          response.
        );
        expect(response.status).to.eq(201);
      }
    );
  });
