Question

我正在使用okhttp3将我的Android应用程序连接到我的mysql数据库，但是在使用FormBody.Builder()时我发现错误（我看到其他人使用此方法）。

我需要执行一个帖子请求。

OkHttpClient client = new OkHttpClient();

     RequestBody formBody = new FormBody.Builder() //this FormBody gives "Cannot resolve symbol FormBody"
            .add("name", reg_name)
            .add("pass", reg_pass)
            .build();

     Request request = new Request.Builder()
            .url(reg_url)
            .post(formBody)
            .build();

看起来你使用的是错误的okhttp版本。确保您的Gradle依赖关系指定如下：

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="container" ng-app="myApp">
        <div class="form-group">
            <div class="row">
                <div class="col-sm-8">
                    <div ng-switch="myVar">
                        <div ng-switch-when="dogs">
                            <div class="pricing-levels-3">
                                <p><strong>Which level would you like? (Select 3 Levels)</strong></p>
                                <input class="single-checkbox" type="checkbox" name="vehicle" value="Bike">Level 1<br>
                                <input class="single-checkbox" type="checkbox" name="vehicle" value="Bike">Level 2<br>
                                <input class="single-checkbox" type="checkbox" name="vehicle" value="Bike">Level 3<br>
                                <input class="single-checkbox" type="checkbox" name="vehicle" value="Bike">Level 4<br>
                                <input class="single-checkbox" type="checkbox" name="vehicle" value="Bike">Level 5<br>
                                <input class="single-checkbox" type="checkbox" name="vehicle" value="Bike">Level 6<br>
                                <input class="single-checkbox" type="checkbox" name="vehicle" value="Bike">Level 7<br>
                            </div>
                        </div>
                        <div ng-switch-when="tuts">
                            <div class="pricing-levels-2">
                                <p><strong>Which level would you like? (Select 3 Levels)</strong></p>
                                <input class="single-checkbox1" type="checkbox" name="vehicle" value="Bike">Level 1<br>
                                <input class="single-checkbox1" type="checkbox" name="vehicle" value="Bike">Level 2<br>
                                <input class="single-checkbox1" type="checkbox" name="vehicle" value="Bike">Level 3<br>
                            </div>
                        </div>
                        <div ng-switch-when="cars">
                            <h1>Cars</h1>
                            <p>Read about cars.</p>
                        </div>
                    </div>
                </div>
                <div class="col-sm-4">
                    <h1>Select a topic:</h1>
                    <select ng-model="myVar" class="form-control">
                      <option value="dogs">Dogs</option>
                      <option value="tuts">Tutorials</option>
                      <option value="cars">Cars</option>
                   </select>
                </div>
            </div>
        </div>
    </div>

（或最合适的版本号）

另外，请务必包含相应的import语句：

compile 'com.squareup.okhttp3:okhttp:3.9.0'

无法解析符号“FormBody” - okttp3错误
